静止无功发生器的特性仿真

Characteristic simulation of static var generator

无功功率的存在,使得电力输配电系统和重工业应用领域面临着各种各样的问题和挑战。电力输配电面临电压波动、低功率因数以及电压失稳等问题;重工业应用,特别是快速、冲击性负荷,可能导致供电网络的电压不平衡、电压波动和闪变等电能质量问题。本文采用Matlab/Simulink软件搭建仿真模型,并对仿真结果进行分析,得到在投入SVG调节下的电压能够处于更加平稳的状态,达到实际无功补偿的根本需求。

Theexistence of reactive power makes electric power transmission and distribution systems and heavy industry applications face various problems and challenges Electric power transmission and distribution faces problems such as voltage fluctuations,low power factors,and voltage instability:heavy industrial applications,especially fast and impulsive loads,maycausepower quality problems such as voltage imbalance,voltage fluctuations,and flicker in the powersupply network.This paper uses Matlab/Simulink software to build a simulation model and analyzes the simulation results It is obtained that the voltage under the SVG adjustment can be ina more stable state,which can meet the fundamental requirements of actual reactive powercompensation.
