Abstract

To solve the problem of the flashover risk assessment of contaminated insulator, a GIS-based region power grid polluted flashover precaution system is proposed in this paper. This system consists of two prediction models that the first is used to estimate contamination condition of insulator and the second is employed to forecast the probability of the flashover in complex weather conditions. The outdoor insulation level of operation insulator can be real-time mastered by using this system, which achieve the accurate flashover prediction and precaution. Then a technical support platform based on GIS is supplied in order to timely avoid the region power grid flashover accident. It is of important practical significance and application value for power grid disaster prevention and reduction.
基于GIS的区域电网污染闪络预防系统的构建
为解决污染绝缘子闪络风险评估问题,提出了一种基于gis的区域电网污染闪络预防系统。该系统由两个预测模型组成,第一个模型用于估计绝缘子的污染情况,第二个模型用于预测复杂天气条件下的闪络概率。利用该系统可以实时掌握运行绝缘子的室外绝缘等级,实现对闪络的准确预测和预防。为及时避免区域电网闪络事故的发生,提供了基于GIS的技术支持平台。对电网防灾减灾具有重要的现实意义和应用价值。
