基于粒子群算法的常规水电站直接厂用电建模研究

分析了当前厂用电考核管理中存在的问题,提出了用直接厂用电率代替综合厂用电率考核电厂厂用电水平。采用经粒子群算法改进的最小二乘法,克服了常规方法拟合误差大的缺点,大幅提高了计算精度,有效地应用于某个西南地区的常规水电站用电量的考核中,取得了良好效果,表明了算法的有效性。

On the Direct Station Service Power Consumption Model for Conventional Hydropower Stations based on Particle Swarm Optimization Algorithm

With an analysis on existing problems in the assessment management of the station service power consumption in hydropower stations, a suggestion is given to replace the current assessment criterion based on the comprehensive pow-er consumption rate by the direct power consumption rate.Then, a calculation model of the direct station service power consumption rate based on the least square method and the particle swarm algorithm is proposed.The improved calcula-tion model is of higher accuracy than traditional methods.The effectiveness of the proposed model is demonstrated by a practical application example in a conventional hydropower station in Southwest China.
