摘要

近年来随着风电大规模接入，系统静态失稳模式由功角失稳主导转向电压失稳主导。基于奇异摄动理论的多时间尺度降阶建模方法，建立了适用于机理分析的风火打捆送出系统简化模型。结合系统功角失稳和电压失稳的判据，利用小扰动法分析了风火打捆送出系统静态安全域边界性质，由功角失稳边界、功角-电压混合失稳边界以及电压失稳边界组成，并提出了3种失稳模式分界点的求解方法。识别风火打捆送出系统静态安全域边界的失稳模式有利于调度员分析系统失稳的主导因素，并有针对性地采取控制措施将系统拉回到安全状态。

Abstract

In recent years, wind power is connecting to the grid on a large scale, and the static instability mode of the system is moving from angle instability to voltage instability. Based on the singular perturbation theory and multi time scale reduced order modeling, a simplified model of wind-thermal-bundled system is established for mechanism analysis. According to the criterions of power angle instability and voltage instability, the boundary properties of the steady-state security region of wind-thermal-bundled system are analyzed with the small disturbance method, which is composed of angle instability boundary, hybrid angle-voltage instability boundary and voltage instability boundary. The solution process of breakpoints of three instability modes are proposed. The results are helpful for the dispatch department to analyze the leading factors of instability and take targeted measures to pull the system back to the safe region.
