光伏电站送出线路电流互感器参数选择的研究

Study on Parameter Selection of Current Transformer for Transmission Line of Photovoltaic Power Station

本文根据光伏电站的实际运行状况,结合相关规范和设计手册,分别对光伏电站配套升压站保护用和测量用电流互感器的一次参数、二次参数选择原则进行分析,使其满足继电保护需要、测量和电能计量需要。最后以具体工程为例,应用选择原则对电流互感器的参数确定加以说明。

According to the actual operation of the photovoltaic power station,combined with relevant specifications and design manuals,this paper analyzes the selection principles of primary and secondary parameters of current transformers for protection and measurement of the supporting booster station of the photovoltaic power station,so as to meet the needs of relay protection,measurement and energy metering.Finally,taking a specific project as an example,the parameter determination of current transformer is explained by using the selection principle.
