摘要
Abstract
Deblock performance of converters is an important ifidex to examine the control strategy of HVDC power transmission project. A well behaved deblock can make the starting process of DC system smoothly and mitigate the disturbance in AC system. The ±660 kV DC power transmission project from Ningdong to Shandong is the first DC power transmission project operated in ±660 kV voltage grade in the world, and the Kick Start strategy from SIMSDYN D teclnique is applied to the deblock of this ±660 kV DC transmission project. The deblock strategy is analyzed and compared with the deblock strategy MUCH2, and the deblock strategy is simulated by physical model of HVDC and tested on actual control and protection platform for the ±660 kV DC power transmission project. When the reference value of current of deblock logic is released to 0.1 pu, the phenomenon of current overregulation in the direction of zero-axi is modified to make the deblock current more smoother.关键词
