摘要
探讨了通用电能质量控制器的工作原理及其基本的系统联结方式,结合稳定直流侧电容电压调节器的控制策略,分析了在相同的电网和负载条件下,不同系统联结方式的通用电能质量控制器功率情况,包括电网和串联控制器、并联控制器、负载等输出和吸收的瞬时功率脉动分量、直流分量及其构成和作用。获得的结论能为UPQC系统联结方式的确定和容量估算及工程应用提供参考。
The basic operation principle of universal power quality controller （UPQC） and its two basic system connections are investigated. Combined with the control strategy for the conditioner to stabilize the dc side capacitor voltage, the powers on the two system connections of UPQC, under the same condition of electric power network and load, are analyzed, including the ac and the dc components in the instantaneous power exported by electric power network and the ones consumed by series controller, parallel controller and load. The constitution of the components and their actions are analyzed, too. The conclusion obtained can provide a reference for determining the system connections of UPQC and capacity estination, and it can also be used in engineering application.
