Static Var Generator
The EasyPQ Static Var Generator (SVG) is composed of a core control unit that integrates an FPGA chip and Infineon's seventh-generation IGBTs. By detecting the reactive current of the load,it actively generates a compensating current that is equal in magnitude but opposite in direction within 10ms, ensuring that the compensated voltage and current remain in phase,thereby enhancing the Displacement Power Factor (DPF) to 1. The compensation method employed is an active current source output.


Bidirectional compensation with high compensation precision



■ It compensates for both inductive and capacitive reactive power

■ Achieve 0.1kVar stepless compensation

■ In a distribution system with a low load factor, the power factor can be sustained at unity

■ The system offers fixed reactive compensation mode

Buick response



■ Total response time < 10ms

 The total response process involves: load current detection, reactive current calculation, and SVG real-time output of compensating current.

■ Transient response time is 12 μs

Transient response time is 12 μs

Total response time < 10ms


Enhance the voltage stability of the power supply system



Under conditions of high load, long transmission lines, and lack of reactive power support, voltage at the end of the line tends to be low, potentially leading to voltage collapse. EasyPQ-SVG can rapidly adjust reactive power, reduce line losses, stabilize voltage on the load side, and thereby enhance the voltage stability of the power supply system.
