陆上风电场升压站继电保护配置

On the Relay Protection Configuration of Booster Station in Onshore Wind Farm

随着陆上风电场装机容量越来越大,为提高陆上风电场环境复杂情况下的运行安全稳定性,基于陆上风电场升压站电网的系统相关性能,结合被保护对象的特点对继电保护进行合理配置,应具有选择性、速动性、灵敏性与可靠性,能有效切除故障或控制故障范围,尽可能地减少短路故障所带来的损失,进而确保整个风电场安全运行。

With the increasing of the installed capacity of onshore wind farms,the relay protection configuration of booster station is of great importance to ensure the operation safety and reliability of wind farms under complex environment.Considering the relevant performance of the connected power grid system,the relay protection should be configured reasonably according to the characteristics of the protected objects.It should be selective,fast-moving,sensitive and reliable.It should be able to effectively cut off the fault or control the fault range to reduce the loss caused by short circuit as far as possible,and thus ensure the safe operation of the whole wind farm.
