600MW机组烟气脱硫系统供电方式的研究

Research on Types of Electric Power Supply of Flue Gas Desulfurization System for 600 MW Unit

针对脱硫高压电源的两种引接方式,以600 MW超临界机组设计为例,阐述了脱硫系统电气的接线形式、保安电源设置及电气设备布置,指出了脱硫系统供电方式中应注意的问题。通过分析及技术经济比较,推荐采用专用脱硫变压器的供电方式。

Aimed at two kinds of connecting method for HV source of flue gas desulfurization system, the connecting methods, locations of emergency power supply and electric equipment are stated, which takes the layout of 600 MW supercritical unit for example. Some problems are pointed out in supply methods of flue gas desulfurization system. It is suggested that special transformer should be applied to flue gas desulfurization system through economic comparison.
