摘要

针对潮流控制器在短路故障工况下易损坏进而影响供电可靠性的问题,为保证其在暂态过程中运行安全的同时实现功能复用,提出一种适用于柔直配电网的双级限流式潮流控制器。该装置具备潮流控制及双级限流功能,稳态工况下可实现线路潮流灵活调节,故障时能快速切换工作状态并根据故障类型实现自适应限流,适用于网络结构复杂的柔直配电网。最后,在PSCAD/EMTDC建立六端环状柔直配电网模型进行仿真分析,验证了所提潮流控制器在潮流控制、多线路协控、故障限流、退控转限等多种工况下的有效性,且满足实用性与经济性。

Abstract

Aiming at the issue that power flow controllers are vulnerable to damage under short-circuit fault conditions, thereby compromising power supply reliability, this paper proposes a two-stage current-limiting power flow controller tailored for flexible DC distribution networks. The proposed controller is designed to ensure safe operation during transient processes while enabling functional reuse. It integrates both power flow control and two-stage current-limiting capabilities: under steady-state conditions, it allows flexible adjustment of line power flow; during faults, it can rapidly switch operational states and implement adaptive current limiting based on fault types, making it suitable for flexible DC distribution networks with complex topologies. Finally, a six-terminal ring-shaped flexible DC distribution network model is established in PSCAD/EMTDC for simulation analysis. The results verify the effectiveness of the proposed power flow controller under various operating scenarios, including power flow control, multi-line coordinated control, fault current limiting, and transition from power flow control to current limiting mode, while also satisfying practicality and economic requirements.
