Abstract

The invention relates to an flexible DC engineering electromechanical-electromagnetic hybrid simulation method comprising the following steps of: acquiring operation parameter data and technical parameter data of a flexible DC project for simulation; The hybrid simulation network of flexible HVDC engineering is divided into regions, the AC power network is divided into electromechanical transientcalculation regions, the DC power network is divided into electromagnetic transient calculation regions, and the position of simulation interface is set. Editing Power Flow Data File and Transient Data File of AC Power Grid Based on Electromechanical Transient Analysis Program; Based on electromagnetic transient simulation program PSD-PSModel, establishing the electromagnetic transient model; combining electromechanical transient model with electromagnetic transient model, a hybrid simulation example of flexible HVDC project is constructed. According to the tidal current result file obtained from the tidal current data file, the key parameters are read to the primary system file of the electromagnetic transient model for initialization setting, and the simulation conditions are set according to the simulation requirements for hybrid simulation calculation.

Description

technical field [0001] The present invention relates to the technical field of power system simulation and control, and more specifically, to an electromechanical-electromagnetic hybrid simulation method and system for flexible direct current engineering. Background technique [0002] As my country's power system enters a new pattern of large-capacity long-distance power transmission, large-scale new energy access, and asynchronous grid interconnection, my country's power grid has gradually formed a complex structure of large-scale AC-DC hybrid connection, which has a great impact on the stability and stability of the entire power system. Control responsiveness makes better demands. As a new generation of advanced DC transmission technology, the flexible DC transmission technology based on modular multilevel converters (MMC-HVDC) has the advantages of independent control of active power and reactive power, no risk of commutation failure, and flexible and independent adjustmen...
