Abstract

The paper presents an algorithm which allows to reduce measurements’ inaccuracy of an instantaneous values of currents and voltages in electrical networks. The considered approaches are used in the prototype stand for the non-sinusoidal power flows modeling based on LabVIEW programming environment using the facilities of modules NI-9225 and NI-9227. Experiment was performed to model non-sinusoidal load flow on the prototype stand for a simple AC 10 kV closed network.

Keywords
