The integrated monitoring and control system for the combined cycle power plant

In this paper, the open and standardized integrated monitoring and control system for the combined cycle power plant was developed and verified. The developed integrated monitoring and control system is monitoring and controlling mainly for the boiler called HRSG (heat recovery steam generator) and BOP (balance of plant) and turbine in the thermal power plant. There were various operating modes frequent start-up and shut-down operations for operating the thermal power plant. Accordingly, the control for the various operating modes and the advanced control for the critical equipments was achieved and developed for the integrated monitoring and control system. As a advanced control algorithm, we adopted a MPC (model predictive controller) MIMO control method. For the integrated monitoring and control system we developed the standardized and open interface APIs (application program interface) to connect to other system efficiently and the function of web monitoring system to manage the remote monitoring and real time historical system. The developed system was verified in the real power plant environment.
