光伏发电站无功系统设计

Research on Reactive Power System Design of Photovoltaic Power Station

大规模光伏发电站接入电网,受交直逆变的影响,对电网运行有极大的影响。为保证电能质量,需进行无功补偿。依据国家规程,结合工程实例,论述实现光伏电站利用逆变器发出无功计算,以减少电容器配置,降低工程造价,保证电网安全、稳定运行。

It has great influence on the operation of power grid which Large scale photovoltaic power station connected to the grid and affected by the AC DC inverter. In order to ensure the quality of electric energy it requires reactive power compensation. According to national regulations and combining with the engineering example, the realization of photovoltaic power station reactive power compensation scheme is discussed. The effect of low drop on the grid ensures network security and stable operation.
