Abstract Calculation stability and precision is one of important index of an excellent numerical calculation algorithm. With the development of power system higher request about the stability and calculation precision of transient stability calculation is put forward. Implicit higher-order Taylor series method has good computing precision, but stability is poorer. In order to improve the implicit Taylor series method numerical stability and can't reduce the calculation precision, a new method that setting the proper values of the parameters is put forward. The method can not only keep the implicit higher-order Taylor series method A-stability but also keep the calculation precision reach 2N order when the Taylor's expansion reaches N order. Calculation speed was analysis in this paper. Simulation experiments show that the method can still maintain the good stability and precision when expanded high order. Otherwise, the method is also suitable for the longer time step size and has the ability for long time dynamic stability simulation.

Key words： Transient stability calculation A stability implicit integration stable region calculation precision
