Implementation and evaluation of a labscale synchrophasor model and applications

Abstract

This paper presents a preliminary implementation of a Labscale Synchrophasor model, where one SEL-2402 (Satellite Synchronized Clock) and SEL-451 relay is installed and properly configured. The synchrophasor data is metered in realtime and displayed graphically. For the purpose of analysis and developing the backend applications, the Phasor Measurement Unit (PMU) data is archived using openPDC. An important backend power system application is then implemented which utilizes the archived synchrophasor data. The application implements an algorithm to screen the moving window of PMU data for event detection. The algorithm uses three different methods to screen for possible events viz., Min-Max method, Fast Fourier Transform method and Pencil-Matrix method. Each method is applied to a moving window of PMU data. The event detection algorithm is tested on the PMU data obtained from the Real Time Digital Simulator (RTDS)
