An rtds-based power system multi-fault type conversion and time-domain control simulator

Abstract

The invention discloses an electric power system multiple fault type conversion and time domain control simulator based on RTDS. The simulator comprises a fault trigger angle selection module, a fault trigger main channel module, a dual fault trigger channel module, a fault type selection module, a single or dual fault selection module and an operating button interface, wherein faults are applied to different trigger angles according to the requirements so that single or dual fault setting can be realized; the single or dual fault duration and the interval time between dual faults can be controllable; and through a function switch, a phase-to-phase fault, a relative fault and an off-line fault for arbitrary single-phase or multi-phase can be realized in an electric power three-phase system. The electric power system multiple fault type conversion and time domain control simulator based on RTDS can effectively reduce the model scale and save the RTDS computing resource, and has no need for realizing setting of multiple fault types through frequent model modification so that the workload of an operator is reduced and the simulation efficiency is improved.

Description
