摘　　要：着重分析负扰动下发电机的功角静态稳定性。借助能量函数方程,推导出瞬态功角极限与稳态功角的解析式,从而可以确定发电机在任何负扰动下是否稳定。在负扰动引起发电机功角不稳定的情况下,本文还推导出瞬态功角与调整功角的解析式,并结合算例,对解析式进行应用和分析。本文解析式的提出,以便于相关的技术人员进行计算和分析,同时对发电机的稳定运行起到一定的指导意义。This article focuses on analyzing power angle static stability of generator under negative disturbance.With the energy function equation,we deduced the analytic expression of transient power angle limit and steady-state power angle,and then it could be confirmed whether the generator was stable or not under any negative disturbances.When the generator was unstable because of negative disturbance,we also deduced the analytic expression of transient power angle and adjusted power angle to analyze and apply for analytic expression by using case study.The analytic expression proposed not only facilitates the relevant technical personnel for calculation and analysis,but also plays a guiding significance for the stable operation of the generator.
