抑制多馈入直流输电系统相继换相失败的协调恢复控制策略
Coordinated recovery strategy for inhibiting continuous commutation failures in multi-infeed HVDC transmission system
摘要
Abstract
A progressive and coordinated recovery control strategy is proposed for continuous commutation failures in multi-infeed HVDC transmission system.The index of Multi-Infeed Operating Effective Short Circuit Ratio consider-ing reactive power which representing the strength of receiving AC system and the extent of coupling between different DC systems, is used as a criterion to determine the order of different DC systems.From the perspective of improving the recovery ability of AC/DC interconnected system, the sequential recovery strategy is employed for multi-circuit DC system to decrease the reactive requirement during the recovery process, so that the continuous commutation failure of multi-circuit DC system can be avoided, and the system can operate safely and stably.The proposed recovery control strategy is implemented on a simple tri-infeed DC system with electromagnetic transient simulation and China Southern Power Grid with electro-mechanical transient simulation, experiment results demonstrate the proposed approach is ef-fective and feasible.关键词
