摘要

组合式直流断路器(ASCB)能有效地处理直流侧故障。针对传统控制策略的不足,提出了两种协调控制策略。其主要思想是采用直流侧过流作为预操作的判据,满足过流时ASCB提前合闸。在提出的策略中,流经主断路器的电流将被减少,以及从邻近变流器向ASCB注入的电流。仿真结果表明了该策略的有效性和可行性。

Optimized Coordinated Control Strategy of Assembly HVDC Breakers for MMC Based HVDC Grids
The assembly HVDC breaker (ASCB) can handle the dc-side fault efficiently. To overcome the shortcomings of the traditional strategy, two coordinated control strategies are proposed. The main idea is adopting the overcurrent in the dc-side as the criterion of pre-operation, and the ASCB will close in advance when it is satisfied. In the proposed strategies, the current that flows through the main breaker will be reduced, as well as the injecting current towards the ASCB from neighboring converters. The simulation result shows that the strategy is valid and feasible.
