The Advantages of Metal Chips Briquetting Machines in Modern Manufacturing

2025-06-06

In the bustling environment of manufacturing and metalworking facilities, the generation of metal chips and shavings is inevitable. These byproducts, often seen as mere waste, can pose significant challenges in terms of handling, cost, and environmental impact. Enter the metal chips briquetting machine—a transformative solution that compresses loose chips into dense, manageable briquettes. This article explores the multifaceted benefits of adopting this technology, underscoring its role in enhancing operational efficiency and sustainability.

Streamlined Waste Management

Metal chips, when loose, occupy substantial space, complicating storage and transportation. Briquetting machines compress these chips into compact blocks, reducing their volume by up to 90%. This drastic reduction allows facilities to store waste more efficiently, minimizing the need for frequent disposal and lowering the number of storage containers required. Transport costs plummet as more material can be shipped in fewer trips, optimizing logistics and reducing carbon footprints.

Can Statcom control harmonics?

2025-06-06

STATCOM (Static Synchronous Compensator) can help control harmonics, but its primary function is not harmonic filtering. Here's how it relates to harmonics:

1. Primary Role of STATCOM:

Reactive Power Compensation: STATCOM provides fast and dynamic reactive power support to regulate voltage and improve power system stability.

Voltage Stability: It helps maintain grid voltage by injecting or absorbing reactive power as needed.

2. Harmonic Impact of STATCOM:

Self-Generated Harmonics: STATCOMs use voltage-source converters (VSCs) with high-frequency switching (e.g., PWM), which can introduce high-frequency harmonics into the system.

Mitigation Through Design: Modern STATCOMs employ:

Multilevel Converters (e.g., cascaded H-bridge, MMC) to reduce harmonic distortion.

PWM Techniques (Sinusoidal PWM, Selective Harmonic Elimination) to minimize harmonics.

Filters (Passive/Active) to suppress residual harmonics.

3. Can STATCOM Actively Mitigate Harmonics?

Limited Direct Harmonic Control: STATCOMs are not primarily designed as harmonic filters, but some advanced configurations (like hybrid STATCOMs with active filtering) can help mitigate harmonics.

Combined Solutions: STATCOMs are often paired with passive filters or active power filters (APFs) to address harmonics effectively.

While a STATCOM alone is not a dedicated harmonic filter, properly designed STATCOMs (with multilevel converters and filters) can reduce harmonic generation. For strong harmonic mitigation, a combination of STATCOM + Active/Passive Filters is typically used.

How should the power factor of single-phase be managed?

2025-06-06

The low power factor of a single-phase circuit will lead to a decrease in equipment efficiency and an increase in line loss. To control the power factor, we need to analyze the causes and take targeted measures. The following are common control methods:

I. Common causes of low power factor

1. Mainly inductive loads

Equipment such as fluorescent lamps, motors, transformers, etc., need to consume reactive power during operation, resulting in a low power factor (usually less than 0.8).

2. Light load or no load

When the actual load of the equipment is far lower than the rated power (such as "a big horse pulling a small cart"), the proportion of reactive power increases and the power factor decreases.

3. Harmonic influence

Non-linear loads (such as inverters, switching power supplies, LED lights) generate harmonics, resulting in voltage and current waveform distortion and deterioration of the power factor.

II. Power factor control measures

1. Reactive compensation (the most direct and effective)

Through parallel capacitors or dynamic reactive compensation devices, capacitive reactive power is provided to offset the reactive demand of the inductive load and improve the power factor.

a. Fixed capacitor compensation

Applicable scenarios: occasions with stable load and small changes in reactive power demand (such as household single-phase motors and small office equipment).

Advantages: low cost, simple structure, and easy maintenance.

Disadvantages: unable to track load changes, may over-compensate (causing power factor to advance).

Installation method: connect the capacitor in parallel at both ends of the inductive load or in the distribution box, and pay attention to the matching of the capacitor rated voltage with the circuit (such as 220V single-phase system).

b. Dynamic reactive power compensation (such as thyristor switching capacitor)

Applicable scenarios: occasions with frequent load changes (such as welding machines, frequency conversion equipment).

Advantages: capacitors can be automatically switched according to real-time reactive power demand to avoid over-compensation.

Disadvantages: high cost and need to be equipped with a controller.

2. Choose high power factor equipment

a. Replace inefficient equipment: replace traditional equipment with energy-saving inductive loads (such as high power factor fluorescent lamps and permanent magnet synchronous motors).

For example: the power factor of ordinary fluorescent lamps is about 0.5, while energy-saving fluorescent lamps with electronic ballasts can reach more than 0.95.

b. Give priority to resistive or capacitive loads: such as electric heating equipment and LED lamps (high power factor models need to be selected to avoid harmonic products).

3. Reasonably match the load to avoid light load operation

a. Adjust the capacity of the equipment: select equipment with appropriate power according to the actual load to avoid "a big horse pulling a small cart".

Example: If the actual power of a single-phase motor is 0.5kW, select a model with a rated power of 0.75kW instead of 1.5kW.

b. Parallel operation or time-sharing use: For light-load equipment, multiple low-power devices can be connected in parallel to replace a single high-power device, or no-load operation can be avoided (such as turning off idle electrical appliances in time).

4. Harmonic control (for non-linear loads)

a. Install harmonic filters: Install LC filters or active power filters (APF) at the front end of non-linear loads (such as inverters and switching power supplies) to suppress harmonic currents and improve power factors.

b. Isolate non-linear loads: Power non-linear loads and inductive loads separately to avoid mutual influence of harmonics.

c. Select low-harmonic equipment: Give priority to electrical appliances that meet harmonic limit standards (such as IEC 61000-3-2), such as switching power supplies with PFC (power factor correction) circuits.

5. Optimize line layout and maintenance

a. Shorten power supply distance: Reduce line impedance and reduce reactive power loss in the line.

b. Regularly maintain equipment: Clean dust from motors, transformers and other equipment to ensure their operating efficiency and reduce reactive power loss caused by equipment aging.

Single-phase power factor control needs to be combined with load characteristics, with reactive compensation as the core, supplemented by equipment upgrades, harmonic control and load optimization. For ordinary users, priority is given to simple and easy capacitor compensation and replacement of high-efficiency equipment; for industrial or complex scenarios, professionally designed dynamic compensation and harmonic suppression solutions are required to achieve safe and economical governance effects.

Low voltage capacitor banks and filter banks

2025-06-06

Both capacitor banks and filter banks are used in low voltage (LV) power systems for reactive power compensation and power quality improvement, but they serve different primary purposes.

1. Low Voltage Capacitor Banks

Purpose:

Reactive power compensation (power factor correction)
Voltage support (reduces line losses and improves efficiency)

Components:

Capacitors (fixed or switched)
Contactors/thyristor switches (for step control)
Protective devices (fuses, overload relays)
Controller (measures PF and switches steps)

Applications:

Industrial plants with inductive loads (motors, transformers)
Commercial buildings to avoid utility power factor penalties
Solar/Wind farms for grid compliance

Limitations:

Can amplify harmonics if system has existing distortion (risk of resonance).
Not designed for harmonic filtering (unless detuned).

2. Low Voltage Filter Banks

Purpose:

Harmonic filtering (reduces THD—Total Harmonic Distortion)
Reactive power compensation (secondary benefit)

Types:

Passive Filters: LC circuits tuned to specific harmonics (e.g., 5th, 7th, 11th), mainly used for factories with VFDs, arc furnaces
Detuned Reactors + Capacitors Series reactors prevent resonance (e.g., 7% or 14% impedance), mainly used for systems with moderate harmonics
Active Power Filters (APF) Electronic compensation (injects opposite harmonics), mainly used for dynamic loads with varying harmonics

Applications:

Data centers (prevent harmonic overheating)
Hospitals (clean power for sensitive equipment)
Industrial facilities with VFDs, UPS systems, etc.
Advantages Over Plain Capacitor Banks:
Prevents harmonic resonance issues.
Reduces voltage distortion and equipment overheating.

3. When to Use Which?

Use a Capacitor Bank if:

Your main issue is low power factor (not harmonics).

Your system has low harmonic distortion (THD < 5%).

Use a Filter Bank (Passive/Active) if:

You have high harmonics (e.g., from VFDs, rectifiers).

You need both power factor correction and harmonic mitigation.

Hybrid Solution: Some installations use detuned capacitor banks (with reactors) to avoid resonance while still improving PF.

1. Overview of the development of the power quality optimization and management equipment industry

Power quality refers to the nature and characteristics of the power provided to users by the power supply system, including voltage fluctuations, frequency stability, harmonic content, voltage flicker, power interruption and other aspects. Good power quality is the basis for ensuring the normal operation of power equipment and the power demand of users.

From the perspective of optimization and management equipment to solve power quality problems, it can be divided into power quality monitoring products, power quality management products, power quality software and services, etc.

In recent years, with the acceleration of my country's industrialization and urbanization process, and the popularization and application of various electronic equipment, the market demand for power quality optimization and management equipment has increased year by year.

Transformer and photovoltaic use at the same time

2025-06-06

Analysis of the situation where the system load exceeds the transformer capacity configuration when the transformer and photovoltaic are used at the same time.

Phenomenon and cause

1. Power fluctuation superposition: The power generation power of the photovoltaic system is affected by factors such as light intensity and weather conditions, and fluctuates significantly. When there is sufficient sunlight during the day, the power generation power may increase significantly in a short period of time; while on cloudy days, cloudy days or in the morning and evening, the power drops sharply. If the system load itself is also in an unstable state at this time, such as the frequent start and stop of large equipment in industrial production, resulting in a large fluctuation in load power, the superposition of the two can easily cause the total system power to exceed the rated capacity of the transformer instantly. For example, in an industrial park equipped with a certain scale of photovoltaic power stations, when clouds suddenly appear in the afternoon to block the sun, the photovoltaic power drops sharply. At the same time, large equipment in several factories in the park starts at the same time, and the system load that was originally close to the upper limit of the transformer capacity is instantly overloaded, causing the transformer temperature to rise rapidly and emit abnormal sounds.

2. Unreasonable planning of photovoltaic installed capacity: When promoting photovoltaic projects, some regions have not fully combined the actual capacity of local transformers and future load growth trends for scientific planning. In order to pursue more photovoltaic power generation benefits, some users or enterprises blindly expand the scale of photovoltaic installations and connect a large number of photovoltaic equipment without in-depth evaluation of the original power supply system. For example, in some old communities, the transformer capacity has not been upgraded for many years. As residents' enthusiasm for photovoltaic power generation increases, they install photovoltaic panels on their roofs, and the total amount of installation far exceeds the transformer's tolerance, resulting in frequent instability in the community power supply, and even frequent tripping during peak power consumption in summer.

3. Insufficient load growth estimation: With economic development and the improvement of people's living standards, various types of electrical equipment are increasing. Whether it is the rise of emerging industries in the industrial field or the popularization of high-power electrical appliances in residents' lives, the demand for electricity continues to rise. If the future load growth estimation is too conservative in the planning stage of the transformer and photovoltaic system, and sufficient capacity margin is not reserved, when the actual load growth rate exceeds expectations, coupled with photovoltaic access, it is very easy to cause the system load to exceed the transformer capacity. For example, in recent years, new stores have been set up in a certain commercial area, and the catering, entertainment and other industries have brought a large amount of new electricity demand. At the same time, photovoltaic systems have been installed on the roofs of some buildings in the area. The capacity of the transformer originally designed can no longer meet the total demand of the existing and new loads and photovoltaic access, and power supply tension often occurs.

Impact

1. Transformer overheating or even damage: When the system load exceeds the transformer capacity, the current of the transformer winding increases. According to Joule's law Q=I2Rt (where Q is heat, I is current, R is resistance, and t is time), the heat generated by the winding increases significantly. Being in this overloaded and heated state for a long time will accelerate the aging of the transformer insulation material and reduce the insulation performance. In severe cases, it may cause a short circuit in the winding, causing damage to the transformer and leading to a large-scale power outage. For example, in a rural distribution network connected to a photovoltaic power station, due to the large number of electrical equipment such as air conditioners turned on during the high temperature period in summer, coupled with the instability of photovoltaic power generation, the transformer was overloaded for a long time, and the insulation material eventually burned out, and the transformer was completely damaged, affecting the normal power supply of many surrounding villages.

2. Power quality degradation: On the one hand, overload operation will reduce the transformer output voltage, resulting in excessive voltage deviation. For some equipment with high requirements for voltage stability, such as precision electronic equipment, industrial automation production lines, etc., low voltage may cause the equipment to fail to work properly or even damage the equipment. On the other hand, the harmonics generated by the photovoltaic system and the load interact when the transformer is overloaded, which may further amplify the harmonic content, affect the power quality of the power grid, and interfere with the normal operation of other electrical equipment, such as causing additional vibration and noise in the motor, reducing the service life of the equipment. For example, in a factory power grid with both photovoltaic access and a large number of industrial equipment, the voltage deviation reached ±10% because the system load exceeded the transformer capacity, causing multiple imported precision processing equipment in the factory to frequently alarm and shut down, and harmonic pollution caused some lighting fixtures to flicker.

3. Reduced power supply reliability: The system load exceeds the transformer capacity configuration, which will increase the risk of power outages. Once the transformer stops operating due to an overload fault, it will directly cause a power outage in the area it supplies power to, affecting residents' lives, industrial production and commercial operations. Even if the transformer is not completely damaged, frequent overload warnings and protection actions will cause intermittent power supply, seriously affecting power supply reliability. For example, in an old neighborhood of a city, due to insufficient transformer capacity and excessive photovoltaic access, there are multiple power outages every week during the peak period of summer electricity consumption, which brings great inconvenience to residents' daily life and also causes economic losses to commercial activities in the neighborhood.

Countermeasures

1. Reasonable planning and capacity expansion: Conduct a comprehensive survey of the existing power grid and load conditions, combine the distribution of photovoltaic resources with future development plans, use big data analysis and load forecasting models to accurately predict the load growth trend. On this basis, scientifically determine the scale of photovoltaic access according to the transformer load rate and remaining capacity. For areas with great load growth potential and rich photovoltaic resources, if the existing transformer capacity cannot meet the demand, the transformer capacity should be expanded and upgraded in time. For example, during the planning stage of a new industrial park, through detailed load research and forecasting, it is expected that the load will increase by 50% in the next 3-5 years. At the same time, considering that a large number of roofs in the park can be used to install photovoltaics, it is finally decided to upgrade the original 1000kVA transformer to 2000kVA, and reasonably plan 500kW photovoltaic access capacity to ensure the stability and sustainability of power supply.

2. Install adjustment equipment: Install a maximum power point tracking (MPPT) device in the photovoltaic system to adjust the working state of the photovoltaic panel in real time so that it always outputs at maximum power and reduces power fluctuations caused by changes in light. At the same time, configure a dynamic reactive power compensation device (SVG) to compensate in real time according to the reactive power demand of the system, stabilize the voltage, improve the power factor, and reduce the load pressure of the transformer. For example, in a rural power grid connected to a 1MW photovoltaic power station, after installing MPPT and SVG devices, the fluctuation range of photovoltaic power was reduced by 30%, and the output voltage deviation of the transformer was controlled within ±5%, which effectively improved the power quality and transformer operating conditions.

3. Optimize operation management: Establish a smart grid monitoring system to monitor the operating status of transformers, photovoltaic systems and loads in real time, including parameters such as voltage, current, and power. Through data analysis, predict possible overload risks in advance and take timely adjustment measures, such as adjusting the output power of photovoltaic inverters and guiding users to use electricity at off-peak times. For example, a city's smart grid monitoring center uses big data analysis technology to conduct real-time monitoring and analysis of transformer and photovoltaic system operating data throughout the city. When it finds that the transformer load rate in a certain area is close to 80% and has a trend of continuing to rise, it sends peak-shifting electricity consumption reminders to large commercial users in the area through a mobile phone APP, successfully avoiding the occurrence of transformer overload.
