| Abstract |
Owing to the need to accommodate the load variation, thermal power plants need a modern controller in order to achieve better frequency regulation, faster response and higher efficiency. For a successful development of the digital instrumentation and control system that can adopt advanced control algorithms, power plant simulator must be available for safe and convenient test. In this paper, a simple drum-type boiler model is proposed using Signal Flow Diagram that describes the system by a combination of basic time responses representing the relationships between cause and effect process variables. After verifying the model and thereafter building a simulator based on the proposed model, we tested the operation of the controller and stability or efficiency of the implemented control algorithms. |
