介绍了并联融冰运行方式的拓扑结构，分析了现有并联融冰运行方式的控制策略，基于成熟的单阀组控制理论和策略，提出了一种将两个并联的换流器进行统一控制的新型控制策略，详细阐述了该控制策略的实现方法。全面梳理了并联融冰运行方式对直流保护功能的影响，分析了相关保护功能的应对策略，然后对关键保护功能提出了新的保护判断逻辑。新的控制保护策略通过了实时数字仿真器(RTDS)仿真试验和现场调试试验，验证了其可行性和可靠性。

The topology of parallel de-icing operation mode is described,and the existing control strategy of parallel de-icing operation mode is analyzed.Then a new unified control strategy of two parallel converters is proposed based on mature single converter control theory and strategy,with the implementation of the new control strategy elaborated.A comprehensive overview about the influence of the parallel de-icing operation mode on DC protection is given,and the coping strategies of the relevant protection are proposed.The new protection criterion logic on the key protection function is put forward.The new control and protection strategies have passed the real-time digital simulator (RTDS) test and on-site tests as proof of its feasibility and reliability.
