Short-circuit current level and it's limited measures for hubei power grid in 2007

With the expanding of the Hubei power grid and the augmentation of its capacity,an effective measure to limit the unceasingly growing short-circuit current of the power grid becomes an important research topic.According to the Hubei power grid's development plan,based on the short-circuit current calculated with PSASP program,the structure for the power grid,the reasons and the impacts for the short-circuit current's growth are analyzed in the paper.And some effective measures to limit the short-circuit current are also proposed.
