Abstract

The invention discloses a method and system for establishing a steady state of a large-scale power grid full-electromagnetic transient simulation model. When the calculation converges, the stable value of the calculation result of the power flow calculation is assigned to the generating set, and the initialization of the simulated power grid model is completed; the simulation is started for the initialized simulated power grid model; when the simulated power grid model is started to run stably When , the simulated power grid model is used as the determined simulated power grid model.

Description

technical field [0001] The present invention relates to the technical field of large-scale power grid electromagnetic transient simulation, and more specifically, to a method and system for establishing a steady state of a large-scale power grid full electromagnetic transient simulation model. Background technique [0002] In recent years, my country has actively developed and utilized clean energy, continuously optimized the energy consumption structure, and achieved remarkable results in energy transformation. With the further acceleration of my country's energy transformation, the pattern of power supply, power grid and load will undergo profound changes. With the large-scale and rapid development of wind energy and solar energy, and the extensive application of new transmission equipment such as UHV DC, flexible DC, and large-capacity FACTS, the characteristics of the power system are becoming increasingly complex, and the development is facing major challenges.
