Bridging the gap between power quality and signal processing
This innovative new text brings together two leading experts, onefrom signal processing and the other from power quality. Combiningtheir fields of expertise, they set forth and investigate varioustypes of power quality disturbances, how measurements of thesedisturbances are processed and interpreted, and, finally, the useand interpretation of power quality standards documents.
As a practical aid to readers, the authors make a clear distinctionbetween two types of power quality disturbances:
* Variations: disturbances that are continuously present
* Events: disturbances that occur occasionally
A complete analysis and full set of tools are provided for eachtype of disturbance:
* Detailed examination of the origin of the disturbance
* Signal processing measurement techniques, including advancedtechniques and those techniques set forth in standardsdocuments
* Interpretation and analysis of measurement data
* Methods for further processing the features extracted from thesignal processing into site and system indices
The depth of coverage is outstanding: the authors present andanalyze material that is not covered in the standards nor found inthe scientific literature.
This text is intended for two groups of readers: students andresearchers in power engineering who need to use signal processingtechniques for power system applications, and students andresearchers in signal processing who need to perform power systemdisturbance analyses and diagnostics. It is also highly recommendedfor any engineer or utility professional involved in power qualitymonitoring.
