| Summary: | The objective of this project is to develop a power quality assessment procedure on a
plant distribution system. This project focuses on identifying and differentiating
features of two voltage sags waveforms caused by fault and large load starting
respectively by using one of the digital signals processing technique, wavelet
analysis. Power quality has become an important issue for electricity consumers at all
levels of usage. It can be defined as the quality of voltage that results in proper
operation of power quality sensitive equipment. It has very wide aspects and elements
and will be discussed further in this report. Wavelets analysis is a windowing
technique which can determine different frequency component of a signal with
different resolutions. Wavelet analysis is very useful in analyzing non-stationary
signals whose characteristics change with time. Then by using the Wavelet Toolbox,
the two waveforms can be analyzed and differentiated. |
