| Automation in thermal power plant is in coal-fired power road slowly in developed, meanwhile, automation development also for our country electric power industry to provide effective basis. In this background, designed and developed a set of DCS system structure based on the opening of the thermal optimization control platform system, and power plants existing DCS software connected to extract from existing DCS production data by complex and intelligent optimization arithmetic, back to the original DCS system, optimize DCS effect.In order to achieve this goal, based on DCS thermal optimization control platform system in the beginning of design is required DCS basic functions, possess and other DCS communication of basic skills, good in custom senior algorithm, can realize the characteristics of thermal as open structure optimization control platform system function. On this basis, the system applied in the power plant in the field production process.Based on the thermal optimization control platform of DCS system configuration, monitoring system based on Windows platforms, realized the friendly user interface and reduce the use of difficulty, But as the site optimization control system core stood using America wind river corporation VxWorks real-time operating system platform, not only can improve the system reliability, stability and maintainability, but also can simplify procedures structure, reduce the complexity of the development, shorten the development cycle.Nowadays, many power plants adopted OVATION system as the main control system, based on DCS, thermal optimization control platform system has the real-time communication ability with OVATION system. Only by optimizing system and optimize the system establishment real-time communication, to realize the good optimization effect, including thermal optimization based on DCS control platform system custom algorithm blocks and complicated algorithm block function, must be based on that can realize complete function. |
