Design Expert System to Simulate Control System of Gas Generating Stations

Abstract

The use of computer technology to support technical decisions and training is now widespread and pervasive across a broad range of technical areas. Accordingly, computer-aided diagnosis has become an increasingly important area for intelligent computational systems. The objective of project research is to design an expert system able to  provide the way to simulate the technical crew training , technical crew evaluating, testing of station parts, fault diagnosing of gas turbine power plant which uses natural gas to help the technical  maintenance crew and others trainees to reduce the error of the technical crew as minimum as possible and significantly reduce the cost of the training technical crew ,and  in same time can be applied this proposed system in all generating stations which work in ministry of electricity and private sector stations. The proposed system contains two main modules first one is the System Information and the second model is Expert system. Those two models creates our system simulators. The Information System of proposed system contains the static information about different malfunctions of the gas turbine power plant field which is used for training crews by showing pictures and videos about affected part of the station and giving the correct action,  and containing exam question for evaluating technical crew level to give the correct decision about them such as an increase training period of the crew,  and containing testing procedure steps of the station parts with given correct action to start  up  the station or wait according  to test result ,and containing fault diagnosing of the station with advice and required solution, and containing information related to monitoring and remote control the station with given correct action using visual Basic 6.0, and can make the prediction and warning  according to environment information and received parameters from station compared with the standard level which is stored in system and giving the required advice to protect the system from damage .The second model of proposed system is Expert system of which performs the program, so this system represents a computer program design to simulate human ability to solve the problem, and it consists of knowledge base which contain all knowledge and information which are collected from experts (engineers) about specific problems in specific domain and inference machine to search for knowledge base to find the solution of the problem in this restricted domain, this research clearly also  describes  how the  neural computing system designed to support the technical decision process to save the station from damage and continuously prepare good technical crew and develop their capability . The most prominent feature of our proposed system is simplicity, flexibility and friendly user interface with high speed of the execution.
