Control Logic Simulation for Distribution Control System (DCS) used in Power Generation

Abstract

Over the last decade, Automation technologies give important changes in the power generation process. These changes have led to significant advances in instrumentation, protection, controllers, I/O modules and other plant automation components. The Distributed Control System (DCS) plays a role of brain for Automated power generation process. The control of large scale generating units is very complicated andit includes the estimation and control of no. of parameters so as to build the general plant efficiency. DCS is in charge of overseeing basic frameworks working in these condition. When the power generation process is large and the control aspects are complex, it is difficult to install DCS directly in real system. For this reason direct implementation on real systems requires big efforts and time investments. Sometime system implementation failure would result in the high asset, time and economical loss. It is also necessary to update DCS because of changes in plant requirement to improve system efficiency and stability. Till now we directly test the real system by trial and error for satisfactory result. Major disadvantage of this method is to shut down the plant process and it will also result in to revenue loss. However, the Simulation of actual Distributed Control System (DCS) is still missing. To overcome this problem, the work presented in this dissertation report describes the Control Logic simulation of the devices used in Distribution Control System (DCS) in Power Generation Simulation tools. It will be helpful to installing / Updating the Distributed Control System (DCS) system in actual application without any problem. So, after satisfactory results we can apply it in actual system. The results for these simulations will be embedded and discussed in the thesis.
