ABSTRACT:The second 750 kV transmission channel project interconnecting Xinjiang Grid with northwest China main grid is one of the key construction projects of State Grid Corporation of China during China’s 12th Five Year Plan. This project, which relates to seven 750 kV substations and twelve 750 kV transmission lines, is an important constituent of 750 kV main network frame of Northwest China power grid and is also an important outward transmission channel of power generated by thermal plants, wind farms and photovoltaic generation stations located in Xinjiang and Northwest China. Through the implementation of this project, a new type of power electronic equipment group for flexible AC transmissions system (FACTS) composed of 750 kV bus-type magnetic-controlled shunt reactor, 750 kV line-type thyristor-controlled shut reactor, 66 kV high-capacity SVC and so on is formed and is the first FACTS equipment group in the world. The research on the system commissioning for this project solves such technical difficulties as the starting-up and voltage control strategy of new equipment located in long-distance weak power grid, the security pre-control of DC transmission system from Qaidam to Lhasa and new energy resources, systematic commissioning of new-type of FACTS equipment and multi-objective security control strategy for grid frame and so on, thus the system commissioning and implementation can be successfully completed. In this paper, the general situation of system commissioning for this project, the research on the system commissioning and the determination of commissioning scheme, main results of on-site commissioning are presented, and these contents are available for reference to putting this project into operation and for the construction of follow-up projects.
