A Graph Theoretical Approach for the Analysis of Cost in Thermal Power Plant

Power crisis has been a long clamour in India and this seems to persist for the coming decade too or so. Cost analysis of power plant can help in improving the efficiency as well as reducing the power plant running cost. The present study puts forward the cost based analysis of the coal based power plant as the way to approach the analysis of a power plant. This thesis present a methodology to evaluate the cost analysis using diagraph and matrix method for Operation and Maintenance cost and Fuel cost in a coal based power plant. Variable Performance Function (VPF) or Performance index is obtained for the Operation and Maintenance and Fuel cost from the attributed matrix. Factors affecting the Operation& Maintenance Cost and Fuel Cost and their interactions are analyzed. For a energy deficient country like India it is important to carry on cost analysis of the coal based power plant which account more the electric power produced than other type of power plant so that their efficiency can be improved to meet the energy requirement in future in India.
