Application Research on General Equipment of 35-750kV Substation of State Grid Corporation in China

In the past, substation construction faced many challenges such as various types of equipment, long equipment ordering period, poor universality of spare parts, repetitive design work, high cost of equipment manufacturing, and difficult operation and maintenance, which seriously restricted the progress of construction and the safe and stable operation of the grid. Since 2006, in order to improve the quality of power grid development, transform the development mode of power grids, promote standardization construction, improve the construction and management efficiency of power grid projects, the State Grid Corporation has organized the research and compilation of general equipment for power transmission and transformation projects. This paper will introduce the research and application of the general equipment of the 35kv-750kv substation of state grid corporation of China from the aspects of the research object, working principle, working process, achievement contents, achievement characteristics and application benefits of the general equipment of the state grid corporation of China, focusing on the research focus and related achievements of the general equipment of the state grid corporation of China in 2018.
