| 摘 要： | 宝钢电厂4号机组是世界上首台可最大燃用1031 km3/h流量BFG的发电机组,燃料系统配置3台双速BFG增压风机。供应方原设计BFG增压风机高低转速切换时,通过电磁阀回路实现风机进口调节档板50%/100%开度的快速切换控制,来确保BFG压力稳定受控。通过调试试验发现切换方案原始设计存在缺陷,工程人员突破原设计思想,摒弃电磁阀切换技术,采用模拟量指令切换的"两步法",成功实现了风机高、低速自动切换及BFG压力的稳定控制。

| Abstract: | Baosteel Power Plant Unit 4 is the first one in the world that has a BFG generator with the maximum flow rate of 1 031 km3/h.It is equipped with three dual-speed BFG booster fans.When the supplier designed the switching program for the BFG booster fans,it was to use the solenoid valve circuit to attain the stability and controllability of the BFG pressure through fast switching the valve position at the fan inlet,either half opened or fully opened.In the debugging process,it was found that there were some d... |
