| description | The invention provides a method for calculating a transient stability domain boundary of a power system, which is used for solving the value of a variable parameter of the transient stability domain boundary and comprises the following steps of: establishing a power system transient model according to a power system state variable vector, a power system algebraic variable vector and a power system variable parameter vector; approaching the transient voltage in the transient model of the power system by using a collocation method to obtain an approximated transient voltage track; acquiring a change rate index of the approximated transient voltage track about a variable parameter; and calculating the value of a variable parameter of the transient stability domain boundary according to the change rate index. According to the method, the workload and time of calculating the transient stability domain boundary can be reduced, and the efficiency of calculating the transient stability domain boundary is improved.
