All these bring unprecedented challenges to the connecting system design of the converter station.

This paper probes into the voltage class and transmission capacity of the connecting system of gas power station,analyzes the influences of the generator on the system after being put into the electric network,and advances the requirements for the switch protection units for generator’s connecting the network.

Using Shaanxi Luneng Jingbian wind power connecting system project as example,the wind farm connecting system voltage level and possible problems that will be met during operation management are analyzed.

Application of one plant,two stations in access system of power plant;
