高压谐波补偿对负载谐波的影响分析与仿真

Analysis and Simulation of the Impact of High Voltage Harmonic Compensation on Load Harm onics

高压静止无功发生器(SVG)为现阶段电力系统最先进的无功补偿技术,通过改进控制算法可实现谐波补偿功能。在现场应用过程中发现有些现场在补偿谐波时,虽然系统侧的电流谐波和电压谐波都在减小,但是负载侧的电流谐波会明显增加。根据现场应用过程中发现的问题进行了分析、建模、仿真,为谐波补偿现场推广应用积累了经验。

High voltage static var gen erator(SVG)is the most adva need reactive power compe nsation tech no logy in the current power system,and harmonic compensation function can be achieved through improved control algorithms.During the on-site application process,it was found that in some sites,although the current and voltage harmonics on the system side are decreasing when compensating for harmonics,the current harmonics on the load side will significantly in crease.Based on the problems discovered duri ng the on-site applicati on process,an a lysis,modeli ng,and simulati on were con ducted,accumulati ng experience for the on-site promotion and applicati on of harm onic compe nsati on..
