基于实时系统数据的电网综合线损分析方法及其应用

为了解决传统线损计算缺少及时性和准确性的问题，提出利用调度自动化系统和管理信息系统的实时系统数据．在线分别生成基于潮流计算的理论线损值、基于状态估计的理论线损值和基于电能计量系统的统计线损值。对计算得到的三种线损数据进行对比分析，提出了综合分析法，并应用于泉州电网。结果表明，综合分析法在提高线损计算的及时性和降损措施的实效性的同时得到更接近于实际线损率的综合线损率。

Line loss comprehensive analytical method based on real-time system data and its application

Line loss comprehensive analytical method based on real-time data of dispatch automation system and management information system is put forward to overcome the main disadvantages of traditional line loss calculation in in-time performance and accuracy. It obtains three kinds of online line loss,i.e. the theoretical value based on power flow,the theoretical value based on state estimation and the statistic value based on power measuring system,and compares them. It is applied in Quanzhou power system,and results show that the comprehensive line loss rate is closer to the actual one while the in-time performance of line loss calculation is improved and the effectiveness of loss reducing is enhanced.
