摘要
分析了350 MW燃煤火电机组引风机高压变频调速改造方案和变频器电气系统接线,针对引风机变频改造后系统中存在的问题,提出了引风机启停逻辑和炉膛负压控制回路的改进方法和建议。
The reconstruction program of high voltage frequency converter of 350 MW coal-fired unit and frequency converter electrical system wiring is introduced. As to the problems of distributed control system after induced draft fan frequency reconstruction, suggestions to improve induced draft fan start/stop control logic and furnace pressure control loop are analyzed. The electricity saving effect is good.
