220kV银城站主变经济运行水平分析与提高

The Analysis and Improvement about Economical Operation of the Main Transformer in 220kV Yincheng Substation

对220kV银城站主变损耗偏高现象进行详细分析,结合对银城变负荷情况分析,通过电网经济运行专家系统软件对两台主变技术特性优劣进行判定,并在此基础上对运行方式进行优化,提高了银城站主变经济运行水平。

This thesis develops detailed analysis about high loss of the main transformer in 220kV Yincheng substation. Comhining analysis about the load of Yincheng substation, this paper judges operation difference hetween the two mains transformers by ＂SOFTWARE OF POWER SYSTEM ECONOMICAL MOVING＂, go a step further, the paper improves operation mode of the main transformers. The practice proves that the measure promotes economical operation of the main transformer in Yincheng substation actually.
