摘要

针对电力系统配电网中

当带负荷母线进行由分列运行方式转换至并列运行方式的倒闸操作时

会产生较大暂态冲击电流

严重威胁电网安全运行的这一问题

设计出一种基于FACTS（柔性交流输电）技术的新型电力系统柔性倒闸装置

通过分析其工作原理

提出电力系统柔性倒闸装置的拓扑结构、建立其数学模型

并运用交叉解耦控制策略和锁相环控制

通过仿真和模拟现场环境样机试验

最终验证了该装置可安全、可靠地实现无环流倒闸操作。

Abstract

In power distribution network

when separate operation mode is switched to parallel operation mode by the bus with load

great transient pulse current will be induced to seriously harm safe operation of the power grid.In this study

a new flexible switching device based on flexible AC transmission system（FACTS） technology is designed for power system. Its principle is analyzed

its topology is proposed

and its mathematical model is established. In this switching device

cross decoupling control strategy and phase-locked control are adopted. It is verified through simulation and field prototype experiment that this device can implement switching safely and reliably without circulating current.
