GY-SVG-PLUS High-spec Static Var Generator
Product Features
Overview
Working principle of the high-configuration model Static Var Generator (GY-SVG-PLUS):
The device connects a voltage source converter (VSC) to the power grid via a filter in parallel. By adjusting the amplitude and phase of the output voltage on the AC side of the converter, it dynamically and accurately compensates for reactive power in the grid system. The transient response time is less than 50 μs, and the full response time is less than 10 ms, thereby avoiding over-compensation and under-compensation. In addition, the device’s neutral line zero-sequence current filtering capability can reach three times the phase line current. It also offers improved EMC electromagnetic compatibility performance and better stability.
Performance characteristics
1.DSP+CPLD full digital control core, three-level topology technology, advanced reactive power detection algorithm, and PWM control strategy.
2.Modular design, supports paralleling of multiple modules, small footprint, easy maintenance.
3.Independent air duct and independent board compartment structure design to ensure stable operation of the device.
4.Equipped with two external current sampling channels, supporting various compensation modes such as low-voltage side sampling with low-voltage side compensation, high-voltage side sampling with low-voltage side compensation, and reactive component compensation.
5.Supports selectable compensation modes: reactive power compensation, or reactive power compensation + three-phase unbalance compensation.
6.Reactive power compensation capability: compensation rate ≥ 99%.
7.Unbalance compensation capability: unbalance degree after compensation ≤ 5%.
8.Neutral line zero-sequence current filtering capability is three times that of the phase line current.
9.Dynamic response speed to load is millisecond level, enabling dynamic and accurate compensation for impact reactive power loads.
10.EMC electromagnetic compatibility: RE and CE items meet Class A test standard.
