Application of FGI Static Var Generator in 60MW fish-light complementary power supply in Fengruitang

1.Overview

The project is located in Fenglitang, Ertang Township, Jinxian County, Jiangxi Province, which is a village in Jiangxi Province. The photovoltaic area of the project covers an area of 1211 mu, and it is planned to build a 110 kV booster station, and is equipped with a 60 megavolt-ampere main inverter.

After the completion of the project, the annual power generation can reach 75 million KWH, can save 22,600 tons of standard coal, 59,200 tons of carbon dioxide, 192 tons of sulfur dioxide, 167 tons of nitrogen oxides, 2,329 tons of soot, 2,216 tons of ash, thereby improving the regional air quality and energy conservation and emission reduction level.

2. Implementation plans

This project uses 15 Mvar static Var generator (SVG) to realize the whole network voltage and power factor compensation and control. Through the implementation of this scheme, the quality of power supply after the unit is connected to the grid is ensured, and the impact on the grid is reduced.

3.Application advantage

The FGI Static Var Generator provides faster compensation with a reactive response time of less than 5ms, enabling accurate and fast compensation for load changes on site.

FGI Static Var Generator has a variety of compensation modes to compensate reactive power, voltage, power factor and other indicators.

The FGI Static Var Generator operating efficiency of the device can reach more than 99% and the loss is small.

The FGI Static Var Generator has the function of automatic switching of time-sharing control. It can automatically switch the operation mode according to the time, reduce the operation and maintenance cost and improve the compensation efficiency.
