摘要
Abstract
Aiming at the problems of small steady-state short-circuit capacity,weak anti-disturbance ability and insufficient transient overvoltage suppression ability of the clean energy base in"Shagehuang"and the near-area system of UHV DC transmission,this study proposes a solution to improve the transient stability and new ener-gy absorption capacity of the system by supporting the natural and regulation characteristics of pumped storage units and large hydropower units in the near area.The power system analysis software package(PSASP)de-veloped by China Electric Power Research Institute is used for simulation calculation,and the influence of sup-porting hydropower units on the new energy absorption capacity under the condition of DC transmission power of 6 000 MW is emphatically analyzed.The results show that the hydropower units can significantly improve the transient stability of the system by increasing the steady-state short-circuit capacity and enhancing the dynamic reactive power support(including deep leading-phase absorption of surplus reactive power,fast voltage regula-tion via automatic voltage regulation(AVR),oscillation suppression using power system stabilizer(PSS)).Under the mode of ring opening and ring closing of Qingxiang—Qingta electromagnetic ring network,the sup-porting three units can improve the new energy absorption capacity by about 1 150 MW and 1 900 MW respec-tively.The research results verify the supporting effect of hydropower units(including pumped storage units)on the transient stability and clean energy absorption of the large base system in"Shagehuang".关键词
