Automatic load sharing of distribution transformer for overload protection (KEY IJP************465)

Abstract

Load variation is a major problem in power system which affects the supply system adversely. Load fluctuation may damage the supply equipment's partially or permanently in a distributed generating system. The load variation at the receiving side of power system is not in our hand, but by using some techniques we can overcome this problem. Load Sharing is an excellent choice for the transformation of load from surplus zone to deficient zone. Load sharing is necessary for a distribution substation when a transformer is overloaded due to rapid increase in electrical load it might be damaged, also the overloading in 3-phase system makes the system unbalanced. With the help of fuzzy logic we can switch the power supply corresponding to the appropriate available load. This project report describes Automatic Load Sharing of Transformer to protect the transformers under overload condition and makes sure the supply is uninterrupted. When load on transformer one exceeds above its capacity then the Secondary transformer that is slave transformer will automatically turn ON. Our main purpose of this project is to give us uninterrupted power supply Our power distribution system works on Transformer, it is main component in the system it it gets overloaded then the supply will stop
