摘要:
有效评估输电线路运行状态是保障输电线路安全、经济运行的主要工作,然而输电线路不同故障类型在各个季节造成风险等级的概率是一个不确定数据,而且需要同时考虑不同故障类型在同一个季节对输电线路风险的影响等级。 文中在对高压输电电路故障种类、原因分析的基础上,针对输电线路运行状态评估时数据的不确定性,建立了输电线路运行状态风险评估 Top-k Skyline 查询模型,应用不确定数据 Top-k 查询的理论建立输电线路运行状态风险等级不确定性数据模型,确定输电线路运行状态的首要风险因素,为输电线路正常运行和状态检修提供决策依据。
Abstract:
Effective evaluation of transmission line operation status is the main work to ensure the safe and economic operation of transmission lines. However, the probability of risk level caused by different fault types of transmission lines in each season is anuncertain data,and the impact level of different fault types on transmission line risk in the same season needs to be considered at the same time. Based on the analysis of fault types and causes of high-voltage transmission circuit,aiming at the data uncertainty of transmission line operation state assessment,the Top-k model of transmission line operation state risk assessment is established,Skyline query model, using the theory of uncertain data Top - k query, establishes the uncertain data model of transmission line operation state risk level,determines the primary risk factors of transmission line operation state, and provides decision - making basis for normal operation and condition based maintenance of transmission line.
