摘要
为大机组火电设备进行外围系统改造,实现全面的自动控制和集中监视的操作功能,提升生产管理的水平与质量,以西门子S7-400PLC系统、工业以太网、HMI为核心的全集成TIA为技术架构,对神头二电厂的两台500 MW机组的循环泵、燃油泵和空压机控制等辅助与公用系统,综合运用S7-400PLC、ET200M远程I/O、WinCC、Profibus总线等技术进行了全面改造,改造效果良好,达到了预期目标。为同类型火电机组的改造提供了参考。
In order for the reconstruction of peripheral system of the high-capacity thermal equipments, the realization of operation functions of overall automatic control and centralized monitoring,and the improvement of production management level and quality, taking Siemens S7400 PLC system and totally integrated TIA as technological framework. , Reconstructions to some auxiliary and public systems were carried out with the application of S7-400PLC, ET200M longdistance I/O, WinCC, Profibus technologies. The result showed good transformation effects, has achieved the expected goal and provided reference for same type units.
