Item Solar PV- diesel hybrid energy system for rural applications(2010) Mandi, R.P.; Yaragatti, U.R.This paper describe sizing of solar PV, DG set and battery bank for different configurations for share of solar power. Different configurations for integration of solar with diesel energy systems are explained in detail. The energy availability and reliability of the integrated energy system are highlighted The economics for implementation of different configurations are dealt with detailed discussion in this paper. ©2010 IEEE.Item Enhancing energy efficiency of auxiliary power system in a 210 MW coal fired power plant through energy efficiency(2010) Mandi, R.P.; Seetharamu, S.; Yaragatti, U.R.This paper describes the results of energy conservation measures in various thermal power plants spread over the country. Energy savings in various major auxiliaries are summarized here with improved performance. Staggering of auxiliary loads, reduction in hydrodynamic resistance of pipes and ducts, adoption of new energy efficient technologies, efficient control techniques, reduction in furnace ingress and monitoring of coal size at mill inlets will lead to substantial amount of energy savings. The energy conservation schemes are economically attractive with a break even period of 1 to 5 years. ©2010 IEEE.Item Energy efficiency improvement of auxiliary power equipment in thermal power plant through operational optimization(2012) Mandi, R.P.; Yaragatti, R.Y.This paper describes the results of energy conservation measures for 210 MW coal fired power plant in various thermal power plants spread over the country. Energy efficiency improvement of major auxiliary equipment with different plant load factors are summarized here with improved performance. The effect of plant load factor on all major auxiliary equipment and suggestions for improving the performance of auxiliary equipment are discussed in this paper. Operation of the plant at improved plant load factor reduced the auxiliary power from 12.05 % at 70 % PLF to 8.74 % at 100 % PLF that reduced the net auxiliary power by 9.1 MU/year and CO2 emission is reduced by about 9,500 t/year. Operating the plant at optimum excess air, controlling the furnace ingress, improving the performance of individual equipment by proper maintenance, etc., improved the plant capacity and reduced the overall auxiliary power by about 1.5-2.1 % of gross energy generation. © 2012 IEEE.
