High Voltage Dynamic Reactive Power Compensation Device SVG reactive compensation device SVG also known as high voltage dynamic reactive power compensation generating device or static synchronous compensator, which is an equipment providing dynamic reactive power compensation through the self-commutated of the power semiconductor bridge converter. High Voltage Automatic Compensator is widely used in petroleum chemical industry, metallurgy, electric power, coal, electric railway, wind power station, as well as some other industrial fields with or near the impact load and large capacity motor. And plays an important role in saving energy and reducing consumption, improving power grid security and stability, increasing power grid power factor, improving power quality, etc. Providing concentrated compensation to improve the power factor for 3~10KV power supply network Based on DSP full digital control system, fast dynamic response time and high control precision Adopt photo electric trigger mode, high potential plate and high voltage-energy, thyristor switched capacitor protection, and strong anti-interference ability
