New concept of rated transient power factor related to an EHV controlled reactor is presented in this paper. The relation between generated harmonics and overvoltage limitation characteristics of the controlled reactor is discussed based on numerical computations. Recommendation of a proper range of rated transient power factor chosen for the benefits of both the harmonics and overvoltage limitations is proposed.

Simulation analysis is carried out for transient power transfer capability of South China Electric Power Grid (SCEPG) in 2005 to research on the influences of various serious disturbances on transient power transfer limit of power transmission from West China to East China. The simulation results show that the monopolar/bipolar block faults in DC system can hardly impact on transient power transfer capacity of SCEPG. Among three DC links, Guizhou-Guangdong DC block impacts on SCEPG most seriously. When single fault occurs in AC system, using a series of the measures, such as reasonably generation scheduling of the generating units in Yunnan and Guizhou province, decreasing critical generators power output and installing SVC in some key buses, can obviously improve transient power transfer limit of power transmission from West China to East China under transient condition.
