Design and Development of Integrated Data Acquisition System to Replace Power Analyser for Power Quality Measurement and Analysis

There are significant fast paced developments within the renewable energy industry and having the ability to efficiently monitor, report and further analyse power quality during prototype testing, which can aid in accelerating the development stages more efficiently, is beneficial for both commercial and research projects alike. Due to the limitations of using a power analyser (PA) for advanced signal processing and storage of raw signal data, a data acquisition (DAQ) system with an embedded real-time controller is proposed as an alternative solution. As such, the application of real-time advanced signal processing is possible for defining developments in innovative technology during testing. Therefore, using a DAQ system as an alternative to a PA allows more flexibility with processing and analysing data during and after testing. This paper presents design, development and initial validation activities for such an alternative.
