ieee paper automatic transformer distribution and load sharing system - renjith - 10-04-2017 Transformer is the vital component in the electric power transmission and distribution system. The problem of overloads, voltage variation and heating effects is very common. It takes lot of time to its repair and also involves lot of expenditure. This work is all about protecting the transformer under overload condition. Due to overload the efficiency gets reduced and the secondary winding gets overheated or it may be burnt. So, by reducing the extra load, the transformer can be protected. This can be done by operating another transformer in parallel with main transformer through comparator and change over relay. The comparator compares the load on the first transformer with a reference value. When the load exceeds the reference value, the second transformer will automatically be connected in parallel with first transformer and share the extra load. Therefore, two transformers work efficiently under overload condition and the damage can be prevented. For home appliances, commercial and industrial loads, the transmitted voltage must be steeped down to a distribution level. This may happen in several phases. In sub-stations the voltage gets stepped down from transmission level (in the tens or hundreds of thousands of volts range) to the distribution level (typically less than 10,000 volts). In this work, a slave transformer shares the load of master transformer in the case of over load and over temperature. A sensor circuit is designed to log the data from master transformer and if it is found to be in overload condition, immediately the slave transformer will be connected in the parallel to the master transformer and the load is shared. Initially when we switched ON the load that load will be shared by the first transformer. Once load has been increased on first transformer above its rated capacity then the stand by transformer (second) will share the load automatically. Here, we used regulated 12V, 500mA power supply, 7805 three terminal voltage regulator is used for voltage regulation. Bridge type full wave rectifier is used to rectify the AC output of secondary of 230/12V step-down transformer. ieee paper automatic transformer distribution and load sharing system - mitshan4u - 10-04-2017 HI am katare sarala i would like a iee paper for load shering by using plc(automation)system..pleas give me the iee paper.i need help on..thanking u.. |
