Abstract

APPLICATION OF SOLAR PHOTOVOLTAIC SYSTEM FOR OPERATING A STEAM POWER PLANT

Dr. Kamaljyoti Talukdar*

ABSTRACT

In this work the thermal energy required by a boiler is obtained by passing high amount of direct current (DC) generated by solar photovoltaic (SPV) modules after passing through a fixed resistance. Also current required by pump in steam power plant is obtained from solar photovoltaic modules after converting into alternating current(AC) by an inverter and the excess current is supplied to rechargeable battery for operating steam power plant during non sunshine hours. In this work boiler pressure is assumed to be 15 MPa, entry temperature of steam to steam turbine (ST) to be 6000C, condenser pressure to be 0.01MPa with dryness fraction of steam 0.8041.The power produced by ST is 1 MW and a supply of 0.68 kg/s of steam is needed to produce 1MW power by boiler. For production of 0.68kg/s,178.256 A current is required considering 100 ohm resistance and for pumping power (10.294 kW), 62.35 A current is required and for that 963 SPV modules in parallel and 2 modules in series of Central Electronics Limited Make PM 150 for January and May in Kolkata city, India. The amount of charge stored and discharged by battery in January and May are 17823 Ah, 3113 Ah and 29084Ah, 3113 Ah respectively.
