SIMPLIFIED APPROACH FOR COMPUTATION OF SEQUENCE IMPEDANCES OF RADIAL PRIMARY DISTRIBUTION SYSTEMS
Publication Date : 01/02/2009
The paper discusses analytical:procedures for computing sequence impedances of radial primary distribution systems. The analysis is based on two approaches. First is the Carson's approach while the second approach, developed by the author, is derived from the capacitive reactance and the inductive reactance of transmission lines and which, for the purpose of this paper, is called the InCap technique. The two techniques were applied to the Gaskiya/Town 11 distribution systems in Zaria town, Kaduna State of Nigeria. The results of the two approaches were comparatively analysed and were found to be consistent with those obtained when the techniques were applied to another distribution system. Conclusions were drawn based on the results and recommendations proposed.
