摘要:

针对由于灾害性事故频发,配电室应急工作面临严峻挑战的现状,文中对配电室电力灾害事故情景推演技术进行研究。在分析配电室电力灾害的突发性、多变性和演变路径的不明确性、复杂性基础上采用“情景-应对”分析法分析配电室电力事故的构成要素以及其作用关系,将处置措施约束时间引入情景构成要素,基于动态贝叶斯网络构建配电室电力灾害情景推演模型。基于时效性原则进行演练效果评价,通过某矿业公司一起6 kV配电室火灾事故进行实例分析,分析结果表明,推演结果与实际灾害发展情形相吻合,表明了配电室电力灾害事故情景推演模型的可行性。

Abstract:

In view of the situation that the emergency work of the distribution room is facing severe challenges due to frequent disasters,this paper conducts a study on the power disaster accident scenario inference technology of power distribution room.Based on the analysis of the suddenness and variability of the power distribution room disasters, the uncertainty and complexity of the evolution path, the "scenario-response" analysis method is used to analyze the components of the power distribution room accidents and their relationships, and the scenario rehearsal model of the power distribution room disasters is constructed based on the dynamic Bayesian network. The effect evaluation of drill is carried out based on the principle of timeliness. A 6 kV power distribution room fire accident in a mining company is conducted case analysis. The results show that the simulation results are consistent with the actual disaster development situation, which indicates the feasibility of the power distribution room disaster scenario model.

Key words: power distribution room, emergency work in the power distribution room, scenario projection, electrical disasters, scenario-response, dynamic Bayesian networks, timeliness, extrapolation model
