SVG plays four key roles in photovoltaic power plants: Grid Stability: Reactive power is essential for the stable operation of the grid. Both active and reactive power work together to maintain stable voltage and frequency. Reactive power acts as the “support force” for the grid, ensuring voltage levels remain steady.
Therefore, it is even more necessary to use SVG reactive power compensation devices reasonably to improve the transmission stability and capacity of the new power system, avoid voltage fluctuations and harm, and ensure low harmonic content, fast response speed, and high reliability in the output of photovoltaic power plants.
The core principle behind SVG is the use of power electronics technology to provide the required reactive power quickly and accurately to optimize power quality. SVG devices utilize power electronic converters, such as Insulated Gate Bipolar Transistors (IGBT), to control reactors connected to the AC side.
on device is required to be 2Mvar--3Mvar. Taking a 10MW photovoltaic power station as an example, a 10MW photovoltaic power station needs to be equipped with about 45 photovoltaic inverters (HT225kW), the reactive power compensation amount of a single inverter is ±148.5kVar, and the total reactive power compensat
