A new software for power flow solution computing using LabVIEW

In this paper we present a new program for solving the power flow problem using the graphical programming environment of LabVIEW as a virtual instrument. This program is used for computing power flow using Newton-Raphson algorithm and DC power flow. Or this latter greatly simplifies the power flow by making a number of approximations. Hence the DC power flow reduces the power flow problem to a set of linear equations. The effectiveness of the method developed is identified through its application to a 6 buses test system. The calculation results show excellent performance of the proposed method, in regard to computation time and quality of results.
