摘    要:状态估计在DMS中具有重要作用,它是配电网络分析的数据之保证。由于配网量测装置配置量极其有限,单靠实时量测难以进行状态估计。通常需引入伪量测,实时负荷数据模型可有效地实现伪量测。日渐发展和完善的负荷管理系统和用电营业系统提供了大量负荷信息,因而该文充分利用负荷管理系统提供的数据和历史用电信息,提出了一种用于实时状态估计的实时负荷数据模型。并根据当前计算机网络技术和供电公司组网的实际情况,制定了实现实时负荷数据模型的网络连接和数据流程。仿真分析表明,该算法具有一定精度,在实际中是可行的,

关 键 词:配电网 状态估计 实时负荷数据模型 负荷管理 电力系统

Abstract:State estimation is an important role in DMS,it is a guarantee to obtain correct data for distribution net analysis.Because of the limit of measuring equipments quantity arranged in distribution net,it is difficult to state estimate only by real time measurement,normally,the pseudo measurement is introduced,the real time load data model can be used to realized pseudo measurement effectivelly.Ever developing and reforming load management system and power supply business system may supply with a large amount of load information.By using the data and historical demand information supplied by the load management system,a real time load data model for real time state estimation is given and according precent computer net technique as well as net forming technique application situation of power supply company,the net connection and data flow of the model is determinated.Simulation shows that the algorithm used possess definite accuracy,which fulfils the practical need.
Keywords:distribution net  real time load data model  load management  state estimation.
