综合气象指数对电力负荷的影响分析

Analysis of the Effect of Compositive Meteorology Index on Power Load

引入了生物气象学中的实感温度、温湿指数、寒湿指数、舒适度指数4个指标来综合衡量气象因素对电力负荷的影响.以重庆市区为例,分析了各综合指数与负荷的关系,并绘制出观测年内的电力负荷与综合指数的关系曲线.分析表明:负荷-舒适度指数比值曲线在整个坐标轴范围内比值很稳定,说明舒适度指数相对于温度能更好地反映电力负荷的变化.同时还定性地分析了降雨量对电力负荷的影响.

The four indexes sensory temperature, temperature-humidity index, cold-humidity index, amenity index in biology meteorology are introduced to compositive analyses the effect of meteorologic factor to power load. Take Chongqing for example, the relation between each compositive index and load is analyzed, and the relation curve of power load and compositive index in observation year is also drawn. The analysis indicates： the load amenity index ratio curve is very stable in all axis range, this indicates amenity index can better reflect the change of power load relative to temperature. At the same time, the effect of rainfall to power load is qualitatively analyzed.
