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.
