STUDY AND ANALYSIS OF 220KV SUB STATION WITH SOLAR GRID INTEGRATION

Abstract

The worldwide increasing demand of agricultural products is very much dependent on the proper irrigation of crops. Now a day’s irrigation system is mainly driven by electric power and is operated using conventional resources. The main challenging problem in such system is that large amount of land is required for transmission of electricity through transmission lines, high KVA ratting transformers are required, higher conductor cost in AC transmission and large amount of protection equipment are required in A.C transmission. Now the limitations of such system using conventional resources can be alternatively handled by making systems using non-conventional resources (PV module), specifically targeted for rural areas of India where mainly agriculture and irrigation is major requirement. In our project work study and feasibility of PV power generation at rural area of western India is performed. For this purpose, a 220KV sub-station in Laxmangarh, Rajasthan is chosen to find out the electricity consumption by rural feeder. Firstly the power consumptions of the specified rural area is measured, thereafter, the solar radiations of this area are computed with the help of software and then the behavior of PV module is checked by the software output. The month wise I-V characteristics and DC voltages are computed and an analytical study is performed. Finally, a 2MW solar power plant and desired DC to DC converter are designed theoretically. Although few limitations and challenges are found while performing analytical study of power plant with solar grid integration, but various advantageous features are obtained and thus make this project beneficial for making power plants using renewable energy resources.
