Quality meter of electric power systems based on IEEE Standard 1459-2000

Abstract

This paper proposes a new method with a new platform for the measurement of the electric power quantities defined in the IEEE Standard 1459-2000 for single-phase, three-phase three-wire and three-phase four-wire power systems. The method consists on the implementation of a SIMULINK algorithm based on the real time domain, which obtains the fundamental positive sequence magnitudes to solve the problem. The platform selected was an embedded PC (Target) that runs the code in the MATLAB xPCTarget environment, with a PCI data acquisition card, which takes the samples of the current and voltage sensors. It can be controlled and monitored by any other PC (Host) via TCP/IP with a COM application installed, specifically created with VISUAL BASIC. The hardware and software unity creates a power quality analyzer called QUAME (QUAlity MEter). Experimental tests and results in a low voltage distribution grid are included to test the platform performance.
