Features

SVG cabinet checks the load current through the external CT and performs computing through the external DSP to analyze the reactive content of the load current. After that, it controls the PWM signal generator based on the settings to send control signals to the internal IGBT. In this way, it generates reactive compensation current to implement dynamic reactive power compensation.

1.Three-level inverter technology, high energy efficiency,
2.Integration of load balancing, power factor compensation, harmonics filtering into one module.
3.Built-in RS485 interface to control intelligent capacitor.

4.High-speed response, Overall response time <7.8ms
5.Load balancing and unloading of neutral wires
6.Flexibility and modularity.

Product display

The static var generator cabinet adopts the hardware structure of FPGA, and the components are of high quality. Thermal simulation technology is used for thermal design of the system, and multi-layer PCB circuit board design ensures reliable isolation of high and low voltage, which provides guarantee for system safety.

Application

Where there is a low-voltage transformer installed and next to large electrical equipment should be equipped with reactive power compensation devices svg static var generator(this is the provisions of the national power department), especially those with low power factor industrial mines, enterprises, residential areas must be installed. Large asynchronous motors, transformers, welding machines, punches, lathes, air compressors, presses, cranes, smelting, steel rolling, aluminum rolling, large switches, electric irrigation equipment, electric locomotives, etc. In addition to incandescent lighting in residential areas, air conditioning, refrigerators, etc., are also reactive power consumption objects that can not be ignored. The rural electricity situation is relatively bad, most areas lack of power supply, voltage fluctuation is very large, power factor is especially low, installing compensation equipment is an effective measure to improve the power supply situation and improve the utilization rate of electric energy. Svg static var generator must the most ideal reactive power compensation device.
