THE PLANT-LEVEL AGC SYSTEM IN THERMAL POWER PLANTS BASED ON JOINT PROGRAMMING OF C LANGUAGE AND SYMPHONY DCS COMPOSER CONFIGURATION LANGUAGE

Directing against the programming of software in plant-level automatic generation control(AGC) system of thermal power plants,a joint programming scheme based on C language of coldfire compiler and Sympony DCS e Composer configuration language manufactured from ABB Corporation in USA has been put forward,solving the problem of limitations existing in complex algorithm of DCS configuration language,realizing complex operations in plant-level AGC system under DCS being developed.The said method is simple and effective,it can also be used in other control systems.
