Abstract: In this paper we are focusing on the power flow, harmonic, transient analysis& reduce the power losses by using different techniques in the GIS TRANSCO network in which the transmission done from 400KV to the distribution of 66KV. With the help of power flow analysis we are able to know about the buses voltage either it is suffer from over voltages or under voltage, it also gives the idea of the ratings of all the equipment and the power flow direction as well as the losses created in the system in megawatt (MW). With the help of ETAP we can also determine the value of current in every branch of the network and also give the idea of flow of reactive power in the system.In this paper we are reducing the loss by changing the taps of the transformer used in the whole system.By changing the taps of the transformer we also increase the load capacity of the whole system as well as reduce the power loss in the system.Transient stability analysis & harmonic analysis has been done to reduce the losses in the system by ETAP.
