Load flow analysis of unbalanced radial distribution systems

Naik, Biswajit and Mudgal, Nikhil and Behera, Somanath (2014) Load flow analysis of unbalanced radial distribution systems. BTech thesis.



A thru tactic for unbalanced three-phase distribution load flow solutions is presented in this work. The distinctive topological characteristics of distribution networks have been fully exploited to make the direct solution possible. For unbalanced distribution system backward sweep is used for calculation of branch current and forward sweep is used for bus voltage. Due to the distinctive solution techniques of the approached method, the time-consuming Lower and Upper decomposition and forward or backward substitution of the Jacobian matrix or Y admittance matrix required in the traditional load flow methods are no longer necessary. Therefore, the approached method is robust and time efficient. Test results demonstrate the validity of the approached method. The approach shows excessive prospective to be used in distribution automation applications.
