Abstract: This paper describes a mathematical model and computational package appropriate for the solution of reactive power compensation problems in industrial networks taking into account all relevant reactive power sources including harmonic power filters. In order to apply the efficient linear programming optimization technique the model has been linearized and a corresponding programming package developed and tested on a real industrial network. The approximation introduced due to linearization has been maintained in acceptable limits through a heuristic correction of optimal reactive injections based on the comparison of voltages and currents obtained on linearized model with results calculations made by the standard Newton-Raphson method. The overall package performances are very promising not only for study purposes but also for possible on-line applications.
Key words: Reactive pover, industrial network, linear programming, optimization.
