Application of Three-Phase Power Flow Analysis to the Nigerian Distribution Networks

Single-phase power flow analysis is used to study most distribution networks in Nigeria. The use of single-phase-power assumes that the network balanced and conductor phases act identically. However, Nigerian are highly imbalanced because untransposed lines, irregularly distributed loads phases, mismatched sizes, spacing. Consequently, single-phase modeling fails reflect actual behavior, resulting an incorrect solution. This research presents three-phase radial for a three-phase-power networks. Olusanya's 54-bus Ajinde's 62-bus Nigeria were evaluated, both which very imbalanced. Without making any assumptions about components, these two properly modeled. Each network's was carried out MATLAB environment. solutions each demonstrated unevenness voltage profile phase, as well inequality real reactive losses indicating deployed mirrored underlying characteristics. Therefore, applying critical proper assessment performance.
