风电场升压站继电保护死区分析及电流互感器优化配置

Relay Protection Dead Zone and Current Transformer Optimization of Wind Farm Substations

风电场升压变电站继电保护装置的有效保护范围取决于电流互感器的配置。当电流互感器配置不够完善时，就会出现主保护的“死区”。本文对升压站保护“死区”的产生进行分析，并论述通过优化配置电流互感器消除主保护“死区”。

The effective range of relay protection in wind farm booster substations depends on the configuration of current transformers. Dead zone occurs when current transformer configuration is not perfect. This thesis analyzes the protection dead zone of wind farm station and optimization of current transformers to eliminate dead zone.
