Title: Motor load transient process calculation method suitable for electromagnetic transient simulation
Inventor: LIAO WEIPING
IPC: G01R31/08
Filed: 2020-04-14
Abstract: The present invention relates to the technical field of power grid transient simulation calculations, and more specifically, to a motor load transient process calculation method suitable for electromagnetic transient simulation, comprising quickly calculating load transient characteristics of an induction motor under symmetrical and asymmetrical fault voltage sags of a power system: (1) first solving a first-order mechanical transient equation of a rotor to obtain changes in rotational speed and slip of the rotor after disturbance; (2) solving a transient potential differential equation in a vector form of the rotor to obtain a change in transient potential; and (3) obtaining current and power responses of the motor after disturbance. Compared with PSCAD/EMTDC electromagnetic transient simulation results, the present invention verifies the effectiveness of the algorithm. Compared with PSD/BPA electromechanical transient simulation results, the present invention shows the calculation advantages of the algorithm under asymmetrical voltage sags. An analytic method explicitly gives calculation expressions for mechanical and electrical parameters of the induction motor after disturbance, and in addition to being used for quickly evaluating the mutual influence between the induction motor and the voltage sags, the method can also be used in stability analysis of the power system.
