摘　　要：电力电容器对于改善功率因数、提高电压质量以及提高电力线路输送容量和稳定性等方面发挥着重要作用,同时电力电容器也是高压直流换流站的重要设备,因此对电力电容器进行测试尤为重要。桥式全谐波电流注入方式是电力电容器测试研究中最值得关注的一种方法,本文设计了基于PLC和触摸屏的可编程谐波电源监控系统,用于监控桥式全谐波电流注入法中的谐波电源。实验表明,该系统操作比较简单,实用性强,可以有效地实现数据监控。Power capacitor plays an important role in the aspects of improving power factor,voltage quality, transmission capacity of power line and stability etc. and, at the same time, is an important equipment of HV DC converter station, therefore the test of power capacitor is of particularly important. In the study of power capacitor test,bridge type harmonic current injection is a kind of method with most attention. In this paper,programmable harmonic power monitoring system based on PLC and touch screen is designed for monitoring harmonic power in the bridge type whole harmonic current injection method. The experiment shows that the system operation is simple, practical and can achieve data monitoring effectively.
