REAL-TIME COST ESTIMATION OF THERMAL POWER STATIONS USING MATLAB
The cost generated per unit in a thermal power station is dependent on fixed cost and variable cost. The duty of an electrical engineer is to generate the power without outage of a power and at the same time the cost of power generated per unit is as low as possible. An engineer can able to reduce the cost of generated power only when the engineer knows on what factors the cost of a generated power depends. Hence the engineer must know on what factors the fixed cost and variable cost may depend. The Central Electricity Regulatory Commission (CERC) has the power of deciding the tariff or electricity generated by various power stations [1]. Tariff is calculated on the basis of fixed cost and variable cost. The power plants have fixed and variable costs. The fixed cost dependent on return on equity, interest on capital loan, depreciation, interest on working capital, operation& maintenance cost, cost of secondary oil. The variable cost dependent on primary fuel costs, secondary fuel oil consumption and auxiliary energy consumption In the Availability Tariff mechanism, the fixed and variable cost components are treated separately.. Cost index is a useful parameter to monitor and compare cost of energy for specific products manufactured by the industry. In the event of an increase or decrease (due to perhaps a conservation measure) in cost index, the particular source can be investigated immediately. In this paper, a case study of three Power Stations namely Simhapuri Thermal Power Station, Nellore, Andhra Pradesh and Koradi thermal power station, Koradi, Nagpur and Sri Damodaram Sanjeevaiah Thermal Power Station, Muthukur, Nellore, Andhra Pradesh has been considered and Tariff calculations, Cost Index of thermal power plants have been implemented with MATLAB Environment and the effectiveness of the work will be verified and compared with real time analysis. The generated program in MATLAB can be applicable for any capacity of Thermal power station and any number of power stations.
