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)
