DISTRIBUTED CONTROL SYSTEM APPROACH FOR A UNIFIED POWER SYSTEM

摘要

This paper presents an approach for applying distributed control system, DCS for a unified power system. It is well known that the distributed control system is usually serves to control, large-scale systems, such as unified power systems, production lines in factories, airplanes, and airport earth services. The proposed distributed control system consists of hardware software and a number of controllers connected through a communication protocol to develop high speed reliable data communications through the various processing elements. This goal can be evaluated by prediction of loading conditions before designing the distributed control system features. The hardware consists of digital input, digital output, analog input, and analog output devices. The software consists of process control, PC, and database systems. The proposed system is examined through a sample controller connected to Aswan hydraulic power plant to indicate it's effect on the studied system response through it's fastness and robustness performance. The results indicate the robustness, very fast response of the proposed distributed control system over the conventional one.
