Problems solved by technology

However, in this environment, the electromagnetic transient simulation of the whole system has a huge amount of calculation, a long calculation time, and the complexity of modeling large-scale power systems is relatively high.
However, in practical engineering applications, when the power system is disturbed, the model is required to quickly and accurately study the stability of the power system, so the existing methods for analyzing the transient stability of the power system cannot meet the needs of actual engineering.

Abstract

The invention discloses a simulating method for an electric power system. The simulating method comprises the following steps: establishing an electromagnetic transient model for each load in the electric power system; performing load flow calculation on the electric power system; allocating the electromagnetic transient models for all loads in the electric power system to a plurality of calculating nodes of a parallel computer and detecting whether the electric power system has disturbance; and after the disturbance occurs, performing parallel electromagnetic transient simulation on each electromagnetic transient model in the electric power system and performing electromechanical transient simulation on the electric power system at next electromechanical transient moment by utilizing an electromagnetic transient simulation result, thereby obtaining an electric quantity parameter of the electric power system after disturbance. Compared with the prior art, the simulating method provided by the invention has the advantages that the accurate electromagnetic transient model is introduced into the electromechanical transient simulation, the calculation accuracy is effectively improved,and each electromagnetic transient model is allocated into each node of the parallel computer, thereby fully utilizing the characteristics of parallel calculation, greatly promoting the calculation efficiency and efficiently promoting the calculation accuracy.

Description

technical field [0001] The present application relates to the technical field of electric power systems, in particular to a method for simulating electric power systems. Background technique [0002] In recent years, my country's electric power industry has developed rapidly, and various power electronic devices such as wind turbines, energy storage devices, and electrified railways have been more and more widely used in power systems. The safe operation of power system has become a research hotspot in academia and engineering circles. [0003] At present, the method of the whole system mathematical model is usually used to analyze the transient stability of the power system, but in the stability analysis of the power system, the mathematical model adopted by each component is not only directly related to the correctness of the stability analysis results, but also has a great impact on the stability of the power system. The complexity of the analysis has a great influence, ...
