摘要

无功自动补偿装置直接关系到电网的可靠运行

研究自动补偿过程中出现的问题对系统优化有重要意义。本文通过对一起安装无功自动补偿装置后

系统出现异常运行情况进行模型简化及数据分析

得出有载调压变压器在不同档位并列运行时

其产生的循环电流会影响对低压侧功率因数测量的结论

并依据规程提出了运行相关建议。

Abstract

Reactive power automatic compensation device is directly related to the reliable operation of power system

study of problems arising during automatic compensation period has important significance to system optimization.In this paper

the abnormal operating condition in the system is subject to model simplification and data analysis after installation of reactive power automatic compensation device

and such conclusion that when the on-load tap-changing transformer is at parallel operation in different tap positions

the circulating current generated can effect power factor measurement at low voltage side are made.And according to the procedure

the relevant operation suggestions are proposed.
