Abstract By the way of BPA short circuit fault simulation of power plant sent line,the paper analyzes the stability conditions of the bus voltage for typical power plants. Combined with transient voltage deviation index and low voltage sustainability indicators, the rule is obtained for the effects of different plant, different types of grid fault on power plant bus voltage. And the method for the bus voltage stability assessment is found, which can be effectively used to evaluate the stability of the power plant bus voltage, and the results shows practical value in engineering.
