Abstract

Abstract:

Construction of power plants with certain levels of informatization 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 cogeneration 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．

Key words: agriculture region, thermal power plant, DCS, DEH
