Stability Control Strategy for Isolated Operation of Power Grid in Turpan Area
Based on the grid structure of Turpan power grid at the end of 2022,this paper compares and analyzes the impact of damping on the oscillation characteristics of the power grid under different modes during the operation of a local isolated grid when the No.1 and No.2 main transformers in 750 kV Turpan substation simultaneously fail and trip.Based on the frequency domain simulation models by cutting off different proportions of wind and photovoltaic output,the optimal stability control strategy for the Turpan Power Grid under isolated grid conditions is proposed.At the same time,it is proposed to establish a 750 kV substation in the Tuokexun area to solve the dynamic stability problem of the local power grid caused by the simultaneous fault tripping of No.1 and No.2 main transformers of the 750 kV Turpan substation.
