Solar Power Charge Controller using LM 324
The demand of renewable energy (alternative energy sources) is increasing day by day as our non renewable sources have started depleting. The other reason for increased demand is that it has a cleaner, easy setup and has a very low cost of maintenance during its operation. Due to which, solar powered equipments and appliances are making its way into various sectors of our day to day life. This research paper deals with the scenario that a storage or battery is needed in order to harness the solar energy when the sunlight is available and supply it in vice versa conditions. For this, a cost effective system is built which charges a battery with the help of solar panel and protection is given to the battery in case of overcharge, deep discharge and under voltage condition. The block diagram, circuit diagram, hardware design are discussed in the paper.
Three Phase Fault Analysis of Power System
The demand of electrical power is increasing day by day for households, agricultural, commercial, industry sectors etc. This paper is developed in order to maintain that electrical power required by these sectors, as in an electrical system, due to line to ground (L-G), line to line fault (L-L), three lines (LLL) various fault occurs. In this paper it has been discussed how to overcome this problem and for this a system is built, which has an auto reclosing mechanism of disconnecting the supply to avoid large scale damage to the control gears, load or manpower in the grid sub-stations. In this way a tripping mechanism is made in order to curb temporary and permanent faults.
