Based on the data of load and power consumptionin Shandong power grid, the authors analyzed the influences of various meteorological factors on power load and powerconsumption by use of statistics method and scatter diagram, and drew the conclusion that the main influencing factor was airtemperature. On this basis a kind of software to analyze thecorrelativity among meteorological factor, load and powerconsumption was developed. The obtained features and regular patterns on the influences of air temperature...
