Abstract

The invention discloses an electromagnetic transient simulation analysis system of an electric power system. The system can set multiple fault conditions by a fully graphical user operating mode, automatically traverse simulation fault models by taking an ATP (Array Transform Processor) as a tool, and selectively save general standard data, a verification filtering algorithm, protection principle, a ranging algorithm and a user-defined algorithm, so as to achieve multiple functions such as harmonic analysis, sequence component analysis and effective value calculation for transient data. The electromagnetic transient simulation analysis system disclosed by the invention has modular and extensible performance, can be used for single setting, process control and data transfer of mass simulation, the design and verification of the user-defined algorithm, as well as multi-angle analysis of transient data in the electromagnetic transient field.

Description

technical field [0001] The invention relates to a power system electromagnetic transient simulation analysis system. Background technique [0002] In power system relay protection, the electrical quantity after a fault is affected by many factors such as fault type, fault location, fault initial angle, transition resistance value, and grid operation mode. For the design and verification of the protection principle, the verification of the distance measurement principle, and the digital simulation verification of the protection device, distance measurement device, wave recording device and other devices, transient data under various combinations of fault conditions and operation modes are required. and corresponding data processing. Comprehensive and effective calculation and verification requires thousands of simulations. If manual intervention is required for each simulation setting and startup, it will take a lot of time and manpower, and there is no guarantee of zero err...
