Research On Comprehensive Control Of Shunda Substation Power Quality

In recent years, due to equipment and nonlinear load in power system exists,the power quality problem has always been a serious problem in Wuhai power network. Long term effects of power quality problems, nearly two years netmain equipment especially the main change due to the impact of a rising trend of damage accident. Before using the traditional static compensationand method of reactive power optimization software to some extent improve the power quality, frequent but a large number of high load start stop and thecompensation capacitor switching has great impact on substation primary equipment, causing a damage caused by equipment, relay protection andautomatic device misoperation and load line power factor is low, poor power quality problems still exist, affecting the safety and stable operation of the grid and the normal production. This paper studies the characteristics of non-linear loads, using FC + TCR reactive power compensation device in substation 35 kV side compensation method for centralized governance. By analyzing the power quality comprehensive control project management on issues arising from. Improvement of power quality are very important to the security and stability of power grid and the user normal production. After study, improve Shunda variable power quality,can reduce a damage of equipment accident, achievement transformation in Wuhai area "after the power has popularizing significance" pollutiongovernance...
