基于单位指标法的辽宁省“煤改电”工程电力需求预测及对电网影响

Power Demand Forecast and Impact on Power Grid of Liaoning Province "Coal to Electricity" Project Based on Unit Index Method

随着辽宁省“煤改电”项目地快速发展,为了科学开展农村电力需求预测及统筹农网规划,保证电力系统的稳定运行,提出了运用单位指标法对铁岭地区工程负荷及农网改造前后负荷进行分析,并对比了“煤改电”工程实施前后农网的负荷特性变化情况,实例计算结果表明“煤改电”工程可改善电网在冬季出现的一些常见问题。

With the rapid development of"coal to electricity"project in Liaoning province,it provides the basis and reference for scientifically carrying out rural power demand forecast and overall planning of rural network to ensure the quality of heating and the stable operation of power system.In this paper,unit index method was selected to analyze the engineering load and the load before and after the transformation of rural power grid in Tieling area,and the load characteristics of rural power grid before and after the implementation of the"coal to electricity"project were compared,and the adaptability of rural power demand was analyzed.The results show that the coal to electricity project can improve the common problems in winter.
