摘　　要：本文以云南电网历史负荷数据为基础,对云南省电网日负荷特性变化规律进行了分析,总结了主要影响因素,定性及定量分析了各因素对日负荷特性指标的影响程度,计算了日负荷特性指标与影响因素的相关系数,建立了日负荷特性与影响因素的回归模型。研究成果为开展负荷预测、制定负荷调控措施等电网规划提供了有效参考依据。Based on the historical load data of Yunnan power grid,analyzes the changes in daily load characteristics of Yunnan power grid, proposes the main influencing factors, uses qualitative and quantitative analysis methods to study the degree of influence of each factor on daily load characteristics indicators, calculates the correlation coefficient between daily load characteristics indicators and influencing factors, and establishes a regression model between daily load characteristics and influencing factors. The research results provide effective reference basis for carrying out load forecasting, formulating load regulation measures and other power grid work.
