摘要

近年来光伏电站建设飞速发展，光伏电站涉网试验是确保光伏电站能够安全、稳定并入电网并正常运行的一系列重要测试。本文以某光伏电站发电单元高电压穿越试验过程为例，介绍了高电压穿越试验方法及试验过程，分析了有功功率异常跌落的原因，为同类试验中类似情形提供参考，也为光伏电站建设期间变压器选型提供借鉴。

Abstract

In recent years

the construction of photovoltaic power station has developed rapidly and the grid - connected test of photovoltaic power station is a series of important tests to ensure safe and stable connection of the photovoltaic power station to the power grid as well as normal operation. In this paper

the high-voltage ride -through test process of a certain photovoltaic power station is taken as an example

the high voltage ride -through test method and process are introduced and the reasons for the abnormal drop of active power is analyzed

which provide reference not only for similar situations in same type of tests

but also for type selection of transformer during the construction of photovoltaic power station.
