Abstract :
This study investigates the effects of network-induced delay of fieldbus networks on the performance of the distributed control of power systems. Profibus and IEC/ISA fieldbus are selected as candidate fieldbus protocols for the distributed computer control of power systems. An integrated discrete-event/continuous-time simulation model of fieldbus networks and super-heater temperature-spray control system of power plant is developed for the performance evaluation of network-integrated control systems. Simulation results show that the performance of control system is heavily dependent upon the traffic load of the network system. The simulation model developed in this study can be very effectively utilized in the design, implementation and operation phases of fieldbus network for the distributed computer control of power systems
