Comparison on Technical Regulations of China and Other Countries for Grid-Connection of Wind Farms

With large-scale development of wind power generation in China,the problems related to grid-connection of wind farms and that of power grid to accept the electric power generated by wind farms come to the fore,however,existing technical standards for grid-connection of wind farms cannot meet the demand of large-scale development of wind power generation and it has been affected on the development of wind power generation and related industries in China.The development of wind power generation in other countries,where the power generation technology is matured,is presented in detail,and characteristics of technical regulations for grid-connection of wind farms in different countries are analyzed,especially the requirements related to active power control,reactive power control and low voltage ride through,which are specified in technical regulations for grid connection of wind farms in these countries,are emphatically researched.On this basis,the differences between the exiting domestic technical regulation for grid-connection of wind farms and technical regulations of other countries are compared and analyzed,and the newly promulgated domestic technical regulation for grid-connection of wind farms is discussed.It is pointed out that the newly promulgated domestic technical standard in this field is not so strict as those in other countries,so that it should be improved in future.
