| 摘 要： | 在基于当地测量量的电压稳定估计方法的基础上,提出了一种低电压减载的计算方法,只需要利用本地的电压和电流,就能够实时判断本地的电压是否失稳,并能准确计算出为使电压恢复而需要的切负荷量.算例表明用该方法可以进行电压稳定的实时监测和控制.

| Abstract: | An undervoltage load shedding method is put forward in this paper based on voltage stability estimation method by local measurements. In this method, only local voltage and current are used to judge whether the local voltage is unstable or not, and the exact amount of load shedding to keep voltage stability can be calculated. Simulations show that it can provide realtime monitoring and control of voltage stability. |
