摘要
由于在三相交流系统中各种复杂、精密、对电能质量敏感的用电设备的不断普及,导致出现了许多电能质量问题,为了改善电能质量问题而出现了各种无功补偿装置;但随着电网结构和电力负荷成分的日益复杂,几种电能质量问题在同一配电系统中同时出现的情况越来越多,若针对每一种电能质量问题都分别采取一种类型的调节装置,会大大增加治理措施的成本,也会影响联合运行的可靠性,由此应运而生出了统一电能质量调节器(UPQC);本文介绍了统一电能质量调节器的基本原理和特点,以及公司首套UPQC设备的基本构成。
Due to the continuous popularization of various complicated,precise and power quality sensitive electrical equipment in the three-phase ac system,many power quality problems have arisen.In order to improve the power quality problems,various reactive compensation devices have appeared;But with the increasingly complex power grid structure and composition of power load,several kinds of power quality problems appeared in the same power distribution system at the same time,more and more for each power quality problems respectively adopt a type of conditioning,will greatly increase the cost of control measures,will also affect the reliability of the joint operation,emerged out of the unified power quality conditioner(UPQC);This paper introduces the basic principle and characteristics of the UPQC and the basic structure of the first UPQC equipment.
