摘　　要：以内蒙古呼和浩特地区某典型接入光伏发电站为研究对象,充分调用光伏逆变器无功输出能力,针对光伏发电站及接入局部系统实际运行方式进行理论计算和仿真研究,按照现场运行实际电压控制需求,进行无功调节仿真分析和现场试验验证。结果为现场试验测试电压变化值与仿真无功调节电压控制值基本一致,验证了充分和优先调用逆变器无功能力可以在一定程度上满足调度对含光伏发电的局部电力系统电压调节需求。A typical photovoltaic power station in Hohhot was selected as the research object.The theoretical calculation and simulation study were carried out for the photovoltaic power station and actual operation mode of the photovoltaic power station access to local system under the reactive power output capacity of photovoltaic inverter full transfered.According to actual voltage control demand of field operatio,simulation analysis of reactive power regulation and field test verification were carried out.The measured value was the same as the simulation result,which verified that transfering the reactive power fully could satisfy the regulating requirement.
