Electrical Energy Auditing in Electricity Distribution Network of Rwanda

The developing country like Rwanda faces High Electricity Distribution Losses within its Network. Electricity Power distribution utility in Rwanda is facing many problems like commercial loss due to various reasons including inefficiencies, and high technical losses. This has a very bad effect on the economic growth of our country. Power system losses in Rwanda comprises of technical losses, non-technical losses & revenue losses. So, there is a need of proper energy accounting and audit in the power distribution system that helps the Utility to compute the energy losses. This paper provides the methodologies used to carry out the proper energy audit including deployment of SMART meters at every Network Grid Object, strengthening the Network extensions, N-1,2.... For this, the calculation of technical losses for HT feeders, power transformers, and secondary distribution system using the SMART meter data approaches. Keywords: technical losses, non-technical losses, Load Imbalances, power transformers, loss load factor, HT feeder), secondary distribution etc.
