摘要
针对动态负荷比例和初始转差率对暂态功角失稳和暂态电压失稳耦合程度的影响,以及互联电网出现功角失稳和电压失稳耦合时,初始转差率和感应电动机比例对主导失稳模式的影响进行了仿真比较研究.仿真结果表明,与初始转差率相比,感应电动机比例对暂态功角失稳和暂态电压失稳耦合程度影响更大,而初始转差率则对主导失稳模式有直接影响.
The influence of dynamic load ratio and initial slip on the coupling degree of transient power angle instability and transient voltage instability,and the influence of initial slip ratio and induction motor ratio on the dominant mode of power angle instability and voltage instability coupling of interconnected power grid are simulated and compared.The simulation results show that the ratio of the induction motor with higher initial slip has a greater influence on the coupling degree of transient power angle instability and transient voltage instability,while the initial slip has a direct influence on the dominant instability mode.
