火电机组热工控制系统改造与人机界面安全

国内首批成套引进的火力发电机组及控制系统服役已超过25年,当时主流的以组装组件式仪表为核心辅以计算机监视及少量计算机DDC、SPC控制,并以BTG模拟盘为人机监控界面的系统,由于存在各种问题,重新规划改造成当前主流的分散控制系统(DCS)是大势所趋。从宝山钢铁股份有限公司电厂的生产实践中,探索新老系统特征及安全可靠性,以使该控制系统顺利运行。

Reconstruction of the Thermal Control System for the Generating Unit and Safety of the Human-computer Interface

It is more than 25 years since the first complete set of generating units and the control system were introduced into China.During that period of time,it was the mainstream to take electronic module assembly instruments as the core with few monitors,DDC and SPC controls as accessory devices.The BTG simulation panel was the system of the human-computer-monitoring interface.As there were a lot of problems in the original control system,it has been a general trend to plan to reconstruct the old system into the...
