[0053] The present invention will be further described below in conjunction with accompanying drawing.
[0054] A kind of power system transient stability simulation method based on implicit numerical integration proposed by the present invention comprises the following steps:
[0055] Step 1: Input the original parameters and information of the system, and perform power flow calculation to obtain the operating variable values under steady-state conditions , including the generator node voltage , the current injected into the network and generator electromagnetic power ;
[0056] Step 2: Calculate the initial value of the state variable power angle , the initial value of angular frequency , the initial value of the state vector subvector composed of the transient and subtransient potential of the generator, the state variables of each dynamic link of the excitation and speed control system ;
[0057] Step 3: Form differential equations and network algebraic equ...
