摘要

研究构网型、跟网型非同步机电源并网系统的暂态同步稳定性,并在实际电网场景下进行仿真验证。首先,根据构网型、跟网型非同步机电源的控制策略,分析影响其暂态同步稳定性的关键因素。随后,在PSCAD/EMTDC中搭建实际电网场景500 kV等值交流系统的时域仿真模型。基于此模型,研究非同步机电源接入实际电网系统的暂态失稳故障表现特征,并验证暂态同步稳定性影响因素的正确性。

Abstract

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.
