Advanced Prediction of Technical Losses on Transmission Lines in Real Time

Active power losses occur during transfer of electricity through transmission grid from power plants to end users. This is a well-known consequence of the current flow through power system elements. The value of the losses on the transmission grid is a few percentages at each voltage level and the value increases with proximity to the grid users. Losses in the transmission network consist of losses on tie-lines and transformers. The paper presents an advanced model for loss monitoring that can provide solutions for verifying measured data and for isolating and analyzing the sources of errors. Monitoring system is based on measurements from electricity meters, SCADA system and PMU (Phasor Measurement Unit). Used equipment must provide measurement standard, assuring highest accuracy, reliability and repeatability.
