optimisation; technical losses; transmissionnetwork; transmitted power

This paper deals with the methodology of softwareto promote optimised operation of the transmission network. Themethodology is based on the real data referring to operatingtemperatures and the power transmitted over 220 kV and 400 kVlines. This is an input database, formed by the values of powertransmitted at a real time temperature. The software designedhere offers a choice of the line to be observed with the option to set the temperature range. The outcome produced will comprise a graphic depiction of operation of the selected transmitter network line with respect to the power transmitted. The graphic depiction of operating course elps show the technical losses associated with the value referring to power transmitted. The methodology of this function has been simulated using an MS Excel sheet.
