Instantaneous Active and Reactive Power Measuring Method in Three Phase Power System
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2005, Vol 4, Issue 6
Abstract
This paper describes an electronic means of measuring the instantaneous active and reactive power absorbed by any electrical equipment. The measurements are based on the Clark (a-b) and Park (d-q) transformations. The system is useful to teach electrical machines in Park’s coordinates and it allows also the study and control of some power electronics converters that are connected to three phase power network, such as static VAR compensator. The principle of the measuring method of the active and reactive power is described, and analyzed for different tests. The effectiveness of the proposed measuring method is confirmed by experimental investigation employing a test system.
