摘要:
混合高压直流输电技术将传统高压直流输电技术的经济性与柔性高压直流输电技术的安全性和稳定性相结合,无疑将成为未来高压直流输电技术的研究热点。 VSC站直流侧故障的快速检测和隔离技术一直是混合直流电网发展的主要技术瓶颈之一。高压直流断路器是解决这一问题的重要手段,也是当前研究的热点。根据高压直流断路器的工作过程,分别对高压直流断路器的故障检测和限流控制进行了分析,提出了基于ROCOV(电压变化率)故障检测方法以及分步投入避雷器的限流策略,减少了断路器的动作时间和故障电流峰值。最后,在PSCAD/EMTDC上进行仿真分析,验证直流断路器保护方案的可靠性和快速性。
Abstract:
Hybrid HVDC transmission technology has become the research focus of HVDC technology in the future because it combines the economy of traditional HVDC technology and the security and stability of flexible HVDC technology. Fast detection and isolation of DC side faults in VSC stations is always one of the main technical bottlenecks in the development of hybrid DC power grid. High-voltage DC circuit breaker is an important device to solve this problem, and it is also a hot spot of current research. According to the working process of high voltage DC circuit breaker, this paper analyzes the fault detection and current limit control of high voltage DC circuit breaker respectively, and proposes the fault detection method based on ROCOV (rate of change of voltage) and a current limiting strategy of operation of arresters by sequence. The strategy can reduce the action time and fault current peak of the circuit breaker. Finally, the simulation analysis is carried out on PSCAD/EMTDC to verify the reliability and speed of the DC circuit breaker protection scheme.
