中文摘要: 提出一种由静止同步补偿器(DSTATCOM)和微网构成的无功电压联合控制系统。在该系统中,微网作为离散子系统提供较大容量的分级无功功率,较小容量的DSTATCOM 作为连续子系统,进行快速连续无功调节,二者协同工作实现无功电压的迅速调整。仿真结果表明,该联合控制系统能较好的平抑电压波动,进一步提高了供电质量,降低了原有电力装置的容量,同时微网无功功率能够实时调度,DSTATCOM 则增加了微网的生存能力,使分布式发电在供能的同时发挥了电能质量调节的作用。
Abstract:A reactive voltage collaborative control system consisting of DSTATCOM and micro-grid is proposed. In this system, small-capacity DSTATCOM as a continuous subsystem for rapid continuous reactive power regulation and micro-grid as discrete subsystem to provide large-capacity graded reactive power. Rapid adjustment of reactive power is realized by their collaborative work. Simulation shows that combined running system could effectively suppress voltage fluctuation. Power supply quality is further improved and original power devices capacity is decreased. At the same time, micro-grid reactive power can be real time scheduled. Micro-grid takes responsibility to regulate power quality, not only provide power supply. It could be more easily accepted by distribution network.
