Wavelet-based of electrical power measurement

الملخص EN

Power and power quality are of most importance in modern energy systems.

The analysis of electrical power measurement is an important consideration to electrical utilities and industrial customers so that diagnosis and mitigation of such disturbances can be implemented quickly.

This paper presents the development of a computer based data acquisition system that provides practical measurement of power components (apparent, active, and reactive) under sinusoidal, non-sinusoidal, stationary and non-stationary conditions by using continuous wavelet transform.

Wavelet transform measuring technique is the more accurate as it has a position analytic ability (analytic of a specified position from the signal of non-sinusoidal waveforms).

This method is fast, efficient and overcomes limitations of the current techniques.

The practical results of the mentioned technique have been compared with the practical results obtained using AC / DC clamp power meter device.
