摘要
针对电网系统运行水平现状,提出基于省级电网运行数据的健康指数理论。基于能源保供的重要性,从运行可靠性与供电稳定性两个维度出发,提出负荷转供率、设备故障占比、重合成功率、故障恢复时间系数、故障电压等级系数五个指标。为确保指标权重计算的合理性,依次求取主观权重、客观权重,并用博弈论法求取综合权重。通过对湖南14个地市跳闸数据的分析与计算,给出不同地市的健康指数水平。最后,测算某地市全年电网健康指数水平情况,分析其健康指数变化与天气的相关性,为电网的实际运行提出建议。
The paper proposes a health index theory based on provincial grid operation data regarding the current operational status of the power grid system.Based on the importance of ensuring energy supply,starting from the two dimensions of safety and reliability and the importance of energy supply,the paper proposes five indexes including load transfer rate,equipment fault ratio,reclosing success rate,fault recovery time,and fault voltage level coefficient.In order to ensure the reasonableness of index weight calculation,the subjective weight,objective weight and comprehensive weight are obtained by game theory method.By analyzing and calculating the tripping data of 14 municipalities in Hunan,the health index levels of different municipalities are given.Finally,the paper measures the health index level of the grid in a local city throughout the year and analyzes the correlation between its health index changes and weather,and provides guidance suggestions for the actual operation of the grid.
