摘要

光伏电站逆变器可发出无功功率

但考虑电站能为系统提供一定的无功储备容量

需配置无功补偿装置。光伏电站无功补偿容量应结合实际接入电网情况确定

其配置的容性无功补偿容量应为光伏电站额定出力时升压变压器无功损耗、线路无功损耗及线路充电功率之和

其配置的感性无功补偿容量应能够补偿全部线路的充电功率。针对光伏电站无功补偿容量配置问题

以实际并网光伏电站工程为例

给出了无功补偿容量的计算过程

并用PSD-BPA潮流计算程序搭建模型

校验了计算的正确性。

Abstract

The inverter in photovoltaic power station can supply reactive power.But considering that power station can provide a definite storage reactive power

the reactive power compensation equipment must be settled.The capacity of reactive power compensation for a photovoltaic power plant is determined by its connection condition to the power network.The arranged capacity of capacitive reactive power compensation is the sum of reactive power loss of step-up transformer

reactive power loss of lines and charging power of lines at rated output of photovoltaic power station.The arranged inductive reactive power compensation capacity shall be able to compensate charging reactive power of all power lines.For the problem of the reactive power compensation capacity arrangement of photovoltaic power station

the calculation process of reactive power compensation capacity is given by taking an engineering example of a grid-connected photovoltaic power station.The model is set up by the use of PSD-BPA flow software and the correctness of calculation is verified.
