Multiprocessor based generator module for a real-time power system simulator

摘要

A novel generator module for a real-time power system simulator was developed. In this simulation module, a multiprocessor and an analog three-phase sinusoidal oscillator are used to simulate the generator behavior. A multiprocessor consisting of four microprocessors solves the differential equations in parallel to lessen the simulation time interval, and uses floating-point arithmetic to obtain high accuracy of the simulations. Any type of generator can be simulated using the developed module, since the parameters of the generator are easily modified by simply changing the data of the multiprocessor program. The initial condition of the power system simulator is automatically set up by a host computer. The accuracy of the generator module is validated by comparisons with the offline simulation program EMTP (Electromagnetic Transients Program).
