SGS static VAR compensation device

Product Description:

1. The reactive current output can be constant within a large voltage variation range, and can still provide strong reactive power compensation when the voltage is low, and can be continuously adjusted in the full range from inductive load to capacitive load, making its reactive power compensation equivalent. 1.4 times to 2 times the same capacity;

2. Continuous and efficient reactive power compensation can be achieved, and the power factor after compensation is >0.98 without overcompensation;

3. The response is faster and can completely replace the original low-voltage reactive power compensation equipment;

4. Active equipment has a wider operating range; it can provide active power within a certain range;

5. Strong ability to suppress specific harmonics; electromagnetic wave noise is significantly reduced;

6. Low power loss and significant power saving effect; it can solve the problem of three-phase unbalance.

The static reactive power compensation device uses dual digital signal processors (DSP) as the core. The self-commutated bridge circuit is connected in parallel to the power grid through the reactor. It uses real-time data acquisition technology and dynamic tracking technology to continuously monitor the voltage and voltage of the power grid and system. Current, while quickly and continuously compensating and adjusting the system's reactive power, can also significantly improve the power quality at the point of continuity between the load and the public grid, improve the power factor, overcome three-phase imbalance, eliminate voltage flicker and voltage fluctuations, and suppress Harmonic pollution, etc., can increase the power factor to a level close to 1.
