基于DCS汽轮机DEH控制系统的优化研究

摘要

Construction of power plants with certain levels of tnformatization and intelligence is required in Xinjiang agricultural region according to the local electric load characteristics. Digital Electric Hydraulic Pressure Control System ( DEH) is a typical form of Distributed Control System ( DCS) used in the steam turbine control. Its use in co-generation power plant improved the overall control unit and realized AGC control. Use of DCS not only effectively optimizes the control function and operation level of the power plant, but also fulfills the real-time balance of supply and demand and thus improves the rural power quality and operational efficiency.%新疆农业区须根据当地农网负荷的规律特性,建设具有一定信息化、智能化水平的电厂.数字电液控制系统(DEH)是现代分散控制系统(DCS)应用在汽轮机控制的典型形式,其在热电厂中的使用,提高了机组整体的可控性,实现了AGC控制,不但有效优化了电厂的控制功能和运行水平,而且满足电能供需实时平衡,提高了农网的电能质量和运行经济性.
