|
摘要
配电台区电力电子化趋势对台区稳定性与供电可靠性提出更高要求,固态故障限流器凭借其控制灵活、动作迅速的特点,更加适应未来电力电子化台区的发展需求。本文在总结典型固态故障限流器的发展与研究现状的基础上,详细推导了桥型固态限流器的数学模型和工作模式,基于PSCAD软件搭建含桥型固态限流器的电力电子化配电台区模型进行仿真研究,仿真结果表明桥型固态限流器具有良好的限流效果,满足电力电子化台区的发展需求。
The power-electronized trend in distribution network will put forward higher requirements about the stability and reliability of the power system. Solid-state fault current limiter can overcome some inherent defects of the traditional fault current limiter by virtue of its flexible control and fast response, which is more suitable for the future distribution network. The state-of-art and development prospect of typical solid-state fault current limiter are summarized in this paper, and the mathematical model and working model of the bridge solid state fault current limiter are deduced in detail. Based on PSCAD software, the model of distribution network with bridge type solid state fault current limiter is constructed. The simulation result shows that the solid state fault current limiter has good current limiting effect and meets the development demand of the power-electronized distribution network.
