Abstract

The definitions of multi-infeed short circuit ratio (MSCR) were analyzed in the paper, which were proved to be equal. The relation between MSCR and traditional short circuit ratio (SCR) was discussed, and it came to a conclusion that the traditional SCR is the particular case of MSCR. Then, the decoupled model of MSCR system was presented in the paper, and based on it, the index of multi-infeed critical short circuit ratio (MCSCR) was given, which could be used as a criteria for weighing the strength of the system. Simulation results show that it is effective to use MSCR for denoting the level of voltage stability.
