摘要： In the present invention, in a case where a stable equilibrium point calculation is not calculable by using a Newton method, a damping factor of a mechanical system differential equation of a generator is set to be greater than an actual value of the generator of the power system. By applying pseudo-transient simulation to the nonlinear differential algebraic equation of the power system including the mechanical system differential equation of the generator, in which the damping factor is set, a norm of a mechanical system equation is found. If the found norm meets a predetermined condition, variable values of the power system at a time when the norm is found are set as initial values of the nonlinear differential algebraic equation of the power system. A stable equilibrium point is determined by applying the Newton method to the nonlinear differential algebraic equation in which the initial values are set.
