Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola

Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola was established on 20th October, 1969 with its head-quarter at Akola. This Agricultural University was named after the illustrious son of Vidarbha Dr. Panjabrao (alias Bhausaheb) Deshmukh, who was the Minister for Agriculture,Govt. of India. The jurisdiction of this university is spread over the eleven districts of Vidarbha. According to the University Act 1983 (of the Government of Maharashtra), the University is entrusted with the responsibility of agricultural education, research and extension education alongwith breeder and foundation seed programme. The University has its main campus at Akola. The instructional programmes at main campus are spread over in 5 Colleges namely, College of Agriculture, College of Agricultural Engineering & Technology, College of Forestry, College of Horticulture and Post Graduate Institute. At this campus 4 degree programmes namely B.Sc.(Agri.) B.Sc. (Hort.), B.Sc. (Forestry) and B.Tech. (Ag. Engg.) , two Master’s Degree Programmes viz. M.Sc.(Agri.) and M.Tech. (Agri.Engg.) and Doctoral Degree Programmes in the faculties of Agriculture and Agril. Engineering are offered. The University has its sub-campus at Nagpur with constituent College, College of Agriculture which offers B.Sc.(Agri.) and M.Sc.(Agri.) degree programmes. The Nagpur Campus is accomplished with a garden, surrounded by its natural beauty and a well established Zoo which attract the general public and visitors to the city. A separate botanic Garden is being maintained on 22 hectares with a green house for the benefit of research workers. In addition there are 2 affiliated grant-in-aid colleges and 14 private non-grant-in-aid colleges under the umbrella of this University A Central Research Station is situated at the main Campus which caters to the need of research projects undertaken by Crop Scientists of the principle crops of the region are Cotton, Sorghum, Oilseeds and Pulses.

    PERFORMANCE ASSESSMENT OF 195 kWp GRID CONNECTED SOLAR PHOTOVOLTAIC POWER PLANT
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2019-08-29) FASEELA, O. A.; Kalbande, Dr. S. R
    The project entitled “Performance assessment of 195 kWp grid connected solar photovoltaic power plant” was installed on the roof top of College of Agricultural Engineering and Technology and Department of Agronomy, Post Graduate Institute, Dr. PDKV Akola and monitored during November 2018 - May 2019. Solar photovoltaic power plant is very good option to generate electricity from a free space like roof top of buildings, barren land etc. The performance analysis was done to understand the working capacity of the power plant. The entire electricity generated by the system was fed into the state grid. The different parameters of the system studied include PV module efficiency, exergy efficiency, reference yield, array yield, final yield, inverter efficiency and performance ratio of the system. The yearly average reference yield, array yield and final yield of the present system were 5.1, 4.5 and 4.4 kWh/kWp/day respectively. The photovoltaic system generates both electrical and thermal energy from solar radiation. Therefore an energy and exergy analysis of the system carried out. Exergy is the maximum work potential which can be obtained from energy. The experimental data were used for the calculation of energy and exergy efficiencies of the PV system. The average photovoltaic efficiency and exergy efficiency were 12.4% and 10.4% respectively. It was observed that the module temperature had a great effect on the exergy efficiency, could be improved by maintaining module temperature close to ambient and that could be achieved by removing heat from the PV module surface. It was concluded that the exergy losses increased with increasing module temperature. Multiple regression analysis was carried out to predict the power output and showed significant results. The average inverter efficiency was found to be 97.1%. The annual mean of monthly energy generation comes to be 26061.5 kWh and total energy injected to grid was 182430.8 kWh during the monitored period. The overall system efficiency was found to be 12.1% with annual supply of 3,12,738 kWh to the grid. The highest performance ratio of 0.91 was observed during March 2019 and the lowest PR of 0.75 obtained during December 2018 due to lowest final yield of 2.9 kWh/kWp/day. The average capture losses and system losses were 0.5 and 0.2 kWh/kWp/day and the losses in the site can be theoretically analyzed were cable losses, energy loss due to grid failure, defective parts, effect of module temperature and wind speed, and energy loss due to dust deposits and bird droppings. The annual mean performance ratio was found to be 0.85 which was found to be satisfactory. The economic analysis was carried out in terms of net present worth, benefit cost ratio and payback period of SPV power plant was found to be Rs. 615089.5, 1.06, and 8 years, respectively. On the basis of techno economic evaluation of the SPV power plant was a good investment for a high initial capital cost which requires less maintenance and a shift to green energy.
