| 摘 要： | 针对配电网中电能质量低的问题,在无功补偿系统中运用新型静止无功发生器(ASVG)实现无功补偿;在分析单周控制(OCC)技术和单周控制新型静止无功发生器(ASVG)工作原理的基础上,利用单周控制形成的PWM波,对单相ASVG进行控制;设计单周控制的数字控制器,达到系统所需的无功补偿效果.对单相ASVG进行建模以及闭环控制的Matlab/Simulink的仿真,并进行实验验证.实验结果表明该装置在单周控制下,直流侧电容电压在工作过程中波动较小,动态响应速度较快,稳态补偿精度能够满足工程中无功补偿的需要.

| Abstract: | For the problem of low power quality in distribution network,advanced static var generator(ASVG)is studied for reactive power compensation;Based on the analysis of one-cycle control(OCC)technique and the principle of advanced static var generator(ASVG),using the PWM which generated by OCC controlled the single phase ASVG.Digital controller to achieve reactive power compensation which the system needs is designed.The modeling and simulation for the single phase ASVG in closed-loop control are completed with Matlab/Simulink software and validated by experiment.The experimental results show that the device in one cycle control,the DC capacitor voltage fluctuation in the working process,the dynamic response speed,steady compensation accuracy can meet the need of wattless compensation in engineering. |
