永城煤电集团滤波装置改造的技术经济分析

Analyses on Technic Economy of Filter Set Remake of Yongcheng Coal-electricity Group

根据对永城煤电集团供电系统中存在的主要谐波情况,翔实分析了其所造成的附加损耗和经济损失。针对永城煤电集团用电负荷造成的谐波现状及现有的固定LC滤波装置的特点,经综合分析最后确定选用TCR型静止动态无功补偿装置与两矿现有的LC滤波装置并联,组成TCR+FC结构。从技术、经济两方面看,具有重大意义。

According to the main harmonic present conditions and the characteristics of yongcheng coal-electricity group power supply system, it has been analyzed in full and accurate for additional power and economy loss caused by harmonic. Through analyses comprehensively on harmonic present conditions caused by power load and having fix up LC filter set of yongcheng coal-electricity group, finally TCR static dynamic reactive compensation set has been chosen and makes up TCR+FC structure and apply to two mines of existing LC filter set. It has an important significance in two aspects of technique and economy.
