In Tuticorin Thermal Power Plant, the thermal energy is converted to mechanical energy and it is converted to electrical energy. The thermal power plant operates on modified rankine cycle with reheating and regeneration. This cycle is a closed cycle. In order to circulate the de-mineralized water in the rate of 700 tons per hour at 175 Kg/Cm2. The de-mineralized water is circulated by boiler feed pump it is coupled with the constant speed motor. In this operation, 15 years back the throttle control was used to control the circulation of de-mineralized water to boiler drum. This throttle control method is inefficient method. To overcome this throttle control is replaced by speed control. The variable speed turbo coupling is used for speed control. The transmission efficiency is more at same percentage of speed. By analyzing the performance curve of the variable speed turbo coupling the most efficient power transmission scoop position is identified. Our project is based on; (1) Analysis of the scoop position at which the power transmission is high by using the performance curve. (2) Analysis of the scoop position at which the boiler feed pump is operating on maximum period in any one unit (TTPS). (3) Analysis to the maximum duration-operated scoop position by which avoiding energy losses due to operating at inefficient energy transmission efficiency position (scoop position) using optimization method genetic algorithm (GA).
