具有改进的操作的电压源换流器
Abstract:
本发明涉及一种电压源换流器(10)，该电压源换流器在两个DC端子(DC1，DC2)之间具有与波形形成器相位脚并联的导向器阀相位脚，其中该导向器阀相位脚和该波形形成器相位脚包括交替操作的上相位臂和下相位臂(V1A，V2A，V1B，V2B，V1C，V2C，WS1A，WS2A，WS1B，WS2B，WS1C，WS2C)，以在该换流器的AC端子上(ACA1，ACA2，ACB1，ACB2，ACC1，ACC2)形成波形，由此允许多个波形形成器相位臂(WS1A，WS2A，WS1B，WS2B，WS1C，WS2C)可以用于其他目的，其中该可用相位臂中的至少一个相位臂被控制成对换流器操作的除了波形形成的其他方面做贡献。
Abstract(English):

A voltage source converter has director valve phase legs in parallel with waveshaper phase legs between two DC terminals. The director valve and waveshaper phase legs include upper and lower phase arms alternately operated to form waveshapes on AC terminals of the converter, thereby allowing a number of waveshaper phase arms to be available for use for other purposes. At least one of the available phase arms is controlled to contribute to other aspects of converter operation than waveshaping.
