Medium voltage dynamic reactive power compensation device

SDrHTC series high-voltage dynamic reactive power compensation devices can adopt instantaneous reactive power theory, harmonic analysis, dynamic measurement and calculation, combination prediction and reasonable action according to the actual reactive power demand of the system and the grouping mode of capacitor banks. All-digital intelligent control system adopts imported high-power thyristors in series to form high-voltage AC non-contact switches. The response time is less than 20ms, and no contact and no inrush current can be realized, quickly change its reactive power to provide dynamic capacitive reactive power for the power system. Reduce reactive power loss, improve the power factor, increase the transmission capacity of the line, adjust the system voltage, balance the three-phase load, improve the power quality, suppress the bus voltage change caused by the fluctuation impact load operation, which is conducive to transient voltage recovery, improve the stability level of the system voltage, improve the production efficiency of users and improve the quality of products.
