Abstract :
The reclosing time of a transmission line has a distinct influence on system stability. A new method of calculating the optimal reclosing time based on the transient energy function (TEF) is presented in this paper. It is shown that an optimal reclosing time can be used to set the autoreclosing device so that the system stability or power transfer capability can be significantly improved. Though power system TEF is based on classical models, the results from simulation studies of a real system (46 generators and 230 buses) with complex models show that the optimal reclosing time calculated using TEF can be used effectively.
