| 摘 要： | 提出了一种在考虑电压骤降对配网可靠性影响中负荷的处理方法。采用SCBEMA (SpecifiedComputerBusinessEquipmentManufacturerAssociation)曲线来表达电压骤降对各种负荷类型的影响 ,这种曲线可以通过CBEMA曲线来获得。最后 ,用模糊成员函数来分别表达电压骤降的幅值和时间对负荷停运的概率影响 ,形成几条典型的曲线。在可靠性分析中 ,计算得到电压骤降幅值和持续时间后 ,通过与这些曲线进行比较可决定哪些负荷会停运。

| Abstract: | A method of load-off in the distribution network taking into voltage sags is presented. The SCBEMA curve is prescribed the effects of voltage sags on different loads. This curve can be obtained by CBEMA curve. Then authors use sigmoid function to simulate the effect of the magnitude and duration of voltage sags on the interruption of the loads. Some curves can be obtained from this simulation, which loads are interrupted can be decided by comparing these curves with the result of the magnitude and duration of voltage sags in the reliability analysis of distribution network. |
