Abstract

The invention discloses a method and system for determining the voltage operation range of a converter bus, and belongs to the technical field of safe and stable operation of a large AC and DC hybridpower grid. The method comprises the following steps: selecting a to-be-checked initial operation mode of a direct current system, and determining an upper limit / lower limit of steady-state voltage ofa converter station bus; according to the initial operation mode, selecting a maximum under-compensation operation mode to determine the steady-state voltage rise of the bus of the DC converter station after the DC bipolar lockout fault; according to the initial operation mode, selecting a direct current restart strategy to determine the steady-state voltage drop of the bus of the direct currentconverter station after the direct current bipolar lockout fault; and determining the voltage operation range of the converter bus during the DC normal operation period. The method is simple and easyto implement, the calculation efficiency can be obviously improved by adding the method in direct current debugging calculation, manpower and material resources are saved, and obvious economic benefits are created.

Description

technical field [0001] The present invention relates to the technical field of safe and stable operation of a large-scale AC / DC hybrid power grid, and more specifically, relates to a method and system for determining the operating range of a commutation bus voltage. Background technique [0002] The basic national conditions of my country's extremely uneven distribution of energy resources and economic development determine that energy resources must be optimally allocated across the country. In order to optimize the allocation of energy resources in my country and meet the economic growth needs of the eastern region, it is necessary to use UHV AC or DC for power transmission. The UHV DC system has the characteristics of large capacity, controllability and flexibility. At present, there are 14 UHV DC projects put into operation in China, namely ±800kV Chusui, Fufeng, Jinsu, Puqiao, Tianzhong and Binjin , Lingshao, Jiuhu, Xitai, Zhaoyi, Yanhuai, Zhaqing, Lanshang and ±1100kV...
