This dissertation presents a method of minimizing electrical losses in radial distribution feeders by the use of shunt capacitors. The engineering benefits of reducing peak electrical power and energy losses are compared to the costs associated with the current engineering practice of buying, installing and servicing capacitor banks in the distribution feeders. The present analysis defines this cost-benefit problem and the formulation of the problem of nonuniform feeders with different wire gauges at various feeder sections. Standard utility capacitor bank sizes are used to give a more realistic model. An original computer solution methodology based on techniques developed for this study determines: (i) Whether it is economical to install compensating capacitor banks on a particular radial distribution feeder or not. (ii) The locations at which capacitor banks should be installed. (iii) The types and sizes of capacitor banks to be installed. (iv) The time setting of switched capacitor banks. The techniques have been applied to a typical radial distribution feeder in Dar-es-Salaam, Tanzania. The results and the engineering implications of this work are discussed and recommendations for the engineering community made.
