基于统计综合法的分时建模研究

The Research of Load Modeling by Online Survey in Different Time Based on Componentbased Method

针对传统统计综合法难于统计,工作量大,模型无法随时间变化调整的问题,文中将负荷按运行时间和运行方式分类,对负荷用户进行抽样调查统计;提出利用营销部门负荷控制系统采集的用户侧功率信息,对日负荷曲线构成进行分析整理,结合调查统计信息,实现在线分时建模,由于日负荷曲线随实际用电情况更新,所以负荷模型参数也可随之调整,并给出了该方法在重庆某站的实际应用情况。

Because of the heavy workload and the model can not change over time based on statistical synthesis method,this paper proposes the use of load control system for marketing department collected power information at user side,analysis the composition of daily load curve,and then combined with the sample survey of users＇ load,the load modeling by online survey in different time is achieved. This paper gives practical application of the method at a station in Chongqing.
