摘　　要：继电保护装置在变电站二次设备中起着不可或缺的作用,保护着电网安全、稳定运行。交流采样插件主要用于继电保护装置二次回路系统的电压、电流模拟量数据采集,继电保护装置利用采集到的数据进行逻辑运算,控制继电器动作、告警等,其结果的准确性直接影响到整个继电保护装置的功能实现以及电力系统安全。为此,设计了一种交流采样插件自动测试系统,测试时可计算交流采样插件各通道比差系数补偿值、角差补偿值,提高了采样值精度,同时大大提高生产测试效率。Relay protection devices play an indispensable role in the secondary equipment of substations,safeguarding the safe,stable,and reliable operation of power grid.AC sampling plugins are mainly used for voltage and current analog data acquisition in the secondary circuit system of relay protection devices.The relay protection device uses the collected data for logical operations to control relay actions,alarms,etc.,and the accuracy of these results directly impacts the functional realization of the entire relay protection device as well as the safety of the power system.This paper designs an automatic test system for AC sampling plugins,which can calculate the compensation values of the ratio coefficient and angle difference of each channel of the AC sampling plugins during testing,improving the accuracy of sampling values and greatly enhancing production testing efficiency.
