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

technical field [0001] The invention relates to the field of power system fault type conversion and time domain control, in particular to an RTDS-based power system multiple fault type conversion time domain control simulator. Background technique [0002] With the rapid development of my country's power system construction, the emergence of RTDS, or real-time digital simulation system, meets the needs of real-time simulation of power systems. RTDS is a computing system specially designed for real-time research on electromagnetic transient phenomena. The real-time simulation of the system consists of hardware and software systems. RTDS hardware part is based on DSP structure, and adopts advanced digital signal parallel processing technology, so as to achieve the purpose of real-time simulation. RTDS can run on the step size of 50μs level, and simulate the large-scale power system in real time. The software system includes accurate models of almost all physical power system ...
