提出了一种 HVDC 转换器的电压控制方案，该方案使用连接到变压器次级绕组上的分接点的旁路晶闸管阀。具有良好的操作特性和低无功伏安吸收值，可以快速、连续地控制直流电压。研究了双向和单向潮流方案的应用，包括换流变压器上没有传统有载分接开关的情况下运行的可行性。
A voltage control scheme for an HVDC convertor is proposed which uses bypass thyristor valves connected to tapping points on the secondary windings of the transformer. Fast and continuous control of the DC voltage is possible with good operational characteristics and low values of reactive volt-ampere absorption. The application to bidirectional and unidirectional power-flow schemes is examined, including the feasibility of operation without the conventional onload tap changer on the convertor transformer.
