Problems solved by technology

[0004] After reviewing the literature, there are quite a lot of literature on line loss calculation that considers unilateral factors, but there are very few line loss calculation methods that comprehensively consider multiple factors such as multiple power sources, measurement information, and international standards. Research literature on online line loss calculation of network is published, but it is basically of an exploratory nature and does not have more practicality

Embodiment Construction

[0018] The present invention will be further described below.

[0019] With the development of technologies such as communications, computers, and smart devices, the use of on-site collection terminals is gradually expanding. The use of these data reflecting the real-time operation of power distribution networks can improve the accuracy of line loss calculations. The data used for real-time theoretical line loss calculation of the distribution network, such as substation voltage, active and reactive power, distributed power point voltage, active and reactive power, etc., may be stored in different databases of different systems, so it is necessary to consider The solution for the data interface between the distribution network line loss calculation system and the SCADA (data acquisition and monitoring) system and other related systems.

[0020] On the basis of the public information model in the IEC61970 series standards, the object-oriented analysis method is used to analyze ...

Abstract

The invention discloses a power distribution network line loss on-line computation method, and belongs to the field of power distribution network line loss computation. The method includes the steps that efficient refining line loss calculation and equivalent rapid calculation under a normal operation mode are carried out at first; then modeling is conducted on a power distribution network line loss computation system on the basis of the IEC61970 / 61968 international standard, and theoretical line loss computation and actual line loss computation are carried out in real time; at last, real-time measurement data of insufficient load points are processed to achieve unified measurement data real-time line loss computation of the whole network. An off-line line loss computation mode in the past is changed, the problems of off-line analysis and data repeated recording are avoided, and real-time computation and analysis of power distribution network line loss changes are effectively achieved.

Description

technical field [0001] The invention relates to an online calculation method for distribution network line loss, in particular to an online calculation method for distribution network line loss considering multiple factors such as multiple power sources and measurement information, and belongs to the field of distribution network line loss calculation. Background technique [0002] Distribution network line loss management is an important content of power enterprise management. Through the real-time theoretical line loss calculation of the distribution network, so as to grasp the weak link and line loss composition of the actual operation of the distribution network, the power enterprise can take targeted and reasonable loss reduction measures to improve the utilization rate of electric energy. [0003] For the calculation of line loss, most of the current research focuses on the analysis of line loss and the study of loss reduction measures, such as: distribution network re...
