Abstract
According to the planned data of Hunan power grid for the year of 2015, the influence of transmitting power via ±800 kV HVDC transmission line from Jiuquan to Hunan power grid on transient voltage stability of Hunan power grid is simulated by power system analysis software package (PSASP) Simulation results show that under the power transmission from Jiuquan to Hunan via ±800 kV HVDC transmission line the number of being operated generating units in Hunan power grid as well as the capacity of switched over capacitor banks are reduced correspondingly, however the reactive power loss of 500 kV electromagnetic looped network in East Hunan will increase, and after the disturbance the ±800 kV HVDC system will absorb large amount of reactive power from 500 kV electromagnetic looped network in East Hunan, thus the ability of voltage recovery of Hunan power grid after the disturbance will be weakened and the transient voltage stability level of Hunan power grid will be decreased.关键词
