基于日负荷曲线的云南电网负荷特性分析

Daily Load Curve-based Load Characteristic Analysis of Yunnan Power Grid

随着我国电力市场的发展和电力技术水平的不断提高,负荷特性调研、分析和预测作为电力市场分析的一项基础工作,对于电力企业的经营和规划发展越来越重要。云南电网具有电源分布不均匀、丰枯电源出力差距大、负荷增长迅速等问题,随着大批水电资源的开发,这些问题会更加突出。此文在详细分析了云南电网历史负荷特性数据的基础上,对影响负荷特性的主要因素做了相应讨论,并对未来云南电网的负荷特性进行了展望。

With developing of power markets and updating of power technique in the country, survey, analysis and forecasting of load profiles become more and more important in opomtion and planning and developing of power enterprises, taken as a basic work for power market analysis. The Yunnan power grid is characterized by uneven distribution of power sources, large difference in power source output between wet season and dry season and rapid increase of load. Along with development of a great quantity of hydropower resources these problems would be even more conspicuous. Having made a detail analysis of historic load characteristics of Yunnan power grid, the paper gives a discussion on the major factors which have influence on load characteristics and forecasts the future load characteristics of Yunnan power grid.
