摘要
就电力系统分岔控制进行了探讨,介绍了鞍结点分岔、跨临界分岔和叉形分岔等与电力系统电压不稳、电压崩溃以及功角不稳和低频振荡等现象密切相关的静态分岔的判别理论和控制方法,分析了它们的理论基础和算法体系,为如何有效地控制这些分岔现象以确保电力系统安全经济地运行提供了理论依据。最后通过一个示例系统说明了电力系统分岔控制的具体操作步骤和闭环控制系统的稳定性分析方法。
The field of Power systems bifurcation control (PSBC) is explored, the discrimination theory and control methods for the steady state bifurcations, i.e., saddle node bifurcation, transcritical bifurcation and pitchfork bifurcation, which are closely related to voltage unstability, voltage collapse, angle unstability and low frequency oscillation, are introduced and their theoretical base and algorithm system are analyzed, so the theoretical basis of how to effectively control these bifurcation phenomena to ensure the power system to operate securely and economically is provided. Finally, the concrete operating procedures of power system bifurcation control and stability analysis method for closed-loop control system are stated by a typical system.
