摘要
提出应用系统控制参数与系统负荷裕度之间的灵敏度关系、对电力系统电压稳定进行控制的方法。首先建立了系统控制参数与系统负荷裕度之间灵敏度的数学模型,在此基础上对系统的各种控制参数的灵敏度值进行计算和排序,最后给出了预防电压失稳的控制方法。仿真结果证实了本方法计算控制参数灵敏度值排序的快速性、准确性以及控制的有效性。
This paper describes the application of sensitivity of the loading margin with respect to parameter on control for voltage stability. The mathematical model of sensitivity is proposed, and then the calculation and the ranking of sensitivity of the parameters are done. And then the control method to avoid voltage instability is given. At last, the approach is illustrated with New-England 39-bus system. The results show the effectiveness of ranking and the very fast computation of the linear estimates and it is helpful to enhance transmission transfer capability of interconnected transmission systems.
