Power Loss Allocation of Balanced Radial Distribution Systems

Gundugallu Peddanna ^[2] | Y. Siva Rama Kishore

Abstract: The distribution system is the final end component of the power system. It holds number of power consumers. These consumers should get power with quality. But when power travels from power stations to consumers power loss occurs. Here two types of loss exist in the power system such as transmission loss and distribution loss. Due to high resistance to reactance ratio in distribution system, losses are high in distribution system in comparison to transmission system. The evaluation of power loss gives an idea of power quality of a system. This paper gives loss calculation using backward and forward sweep based load flow method. The basic aim of this work is to evaluate the power loss and voltage schedule in the distribution system. In this paper two conditions are mainly considered in case of radial distribution system nature. (1) The radial distribution system without laterals ( only main feeder) (2) The radial distribution system with laterals and sub laterals (main feeder along with laterals and sub laterals) The distribution system power flows are executed for both cases using simple equations. Here 10-bus, 12-bus, 15-bus, 28-bus, and 69-bus balanced radial distribution systems are analyzed.
