一种用于配电网的综合补偿限流措施

A new integrated compensation and fault current limit methodfor distribution power system

针对目前应用于配电网的补偿和限流方法存在的问题,提出了一种基于有源加压(ActiveVoltageInjec tion)原理的新型综合补偿限流措施.首先对AVI限流的暂态过程进行了分析;然后尝试将限流和补偿两种功能用同一装置完成,给出了主电路结构以及软硬件的设计思路和PWM方式的选择,通过仿真验证了此方法的可行性.

Based on existing problems of compensation and current limit methods for distribution power system, a new integrated compensation and fault current limit method based on Active Voltage Injection (AVI) theory is proposed. Transient process of AVI current limit is analysed at first; then this paper tries to achieve compensation function and current limit function by one device, main circuit structure, hardware/software design methods and choice of PWM mode are given. The feasibility of this technology is validated through simulation.
