110 kV NETWORK TECHNICAL LOSSES ASSESSMENT. REAL DISTRIBUTION SYSTEM CASE STUDY

The paper is focusing on evaluating the technical losses within a real distribution network. The study was conducted for a distribution system operator within the Romanian Power System. The analysed area is represented by a real part of the Romanian Power System. It is modelled in a computer aided power system analysis tool. Several power system operating conditions are analysed. Power system optimization measures are provided having as a goal to reduce the technical losses' value. Values obtained based on the field measurement are compared to the ones provided by computer simulations. These conclusions are very useful for the distribution network operator.
