光伏电站高电压穿越能力测试分析

Test analysis on high voltage ride through capability in photovoltaic power station

为保证光伏发电站在高电压穿越期间能够持续运行,基于高电压穿越测试装置阻抗/阻容升压原理,开展了单台逆变器现场高电压穿越能力测试。测试结果表明,光伏发电站单台逆变器在实际运行中具有高电压穿越能力,可为开展大规模光伏电站集中接入电网的高电压穿越能力评估提供参考依据。

In order to guarantee the continous operation of the photovoltaic power station during the high voltage ride through,based on the resistance-capacitance voltage boost principle of high voltage ride through test device,the high voltage ride through field test of the single inverter is carried out.The test resuluts show that the single inverter of the photovoltaic power station has high voltage ride through capability,which can provide the reference basis for high voltage ride through evaluation of the integration of the large scale photovoltaic power station with the power grid.
