ANALYSIS OF TRANSIENT SYNCHRONIIATION STABILITY OF POWER SYSTEM WITH GRID-FORMING/GRID-FOLLOWING NONSYNCHRONOUS-MACHINE SOURCES
The transient synchronization stability mechanism of the grid-forming converter and the grid-following converter is studied,and the simulation verification is completed based on the actual power grid scenario.Firstly,according to the control strategy of the nonsynchronous-machine sources,the key factors influencing its transient synchronization stability are analyzed.Then,the time domain simulation model of 500 kV equivalent AC system of Zhejiang Jinhua is built in PSCAD/EMTDC.Based on this model,the transient instability characteristics after short-circuit faults of the actual power gird with nonsynchronous-machine sources are studied,and the key factors influencing the transient stability are verified by simulation.
