In the paper a procedure of short-term measured power samples optimal averaging period tracking is proposed. Usually, short-term (in the scale of fraction of a second) power consumption fluctuates due to operation of variety of network connected switching mode loads. The aim of the suggested tracking procedure is to reduce averaged power measurements statistical deviation in AC electrical distribution...
In the paper a new method for remote wattmeter calibration is introduced. The implementation of such a type of calibration becomes possible if a remote and a reference wattmeter are connected to the same electrical grid and are equipped with data communication channel. This is a typical situation in smart grid. The main idea of the method is based on switching additional not necessarily precisely...
