Abstract

The invention discloses a digital simulation of an electric power system which is deep in the fields like planning, designing, running and researching of the electric power system. The simulation result of the digital simulation becomes the main foundation for the decisions in the fields. A load is used as the important composition part of the electric power system; the model and the parameters of the load have important effects on the digital simulation result of the electric power system. Building an accurate load model is a universal difficulty due to the composition complexity of the load. The digital simulation carries out simulation analysis on a plurality of running modes and a plurality of failure modes of a northwest power network and carries out comparison analysis on the wave recording result of a plurality of failures based on a synthesized load model (SLM) which more reasonably considers the line of a distribution network in structure.

Description

technical field

[0001] The invention relates to a simulation and calculation of a power system, in particular to a modeling method of a load model of the power system. Background technique

[0002] There are three ways of load modeling: statistical synthesis method, overall measurement and identification method and load modeling method based on accident simulation. Fault fitting is a load model modeling method based on power system accident simulation. The "accident" here refers to both occasional power system accidents and artificial disturbance tests such as short circuits; load "modeling" based on accident simulation is usually not "from scratch" load modeling, but often through The accident simulation verifies the original load model, and if necessary, the load model parameters need to be adjusted according to the accident simulation results.

[0003] A common situation in engineering practice is: when a power system starts to perform simulation calculations in the ear...
