Instalación de un Sistema de Monitoreo Sincrofasorial en una Red de Pruebas de Laboratorio del Instituto de Ingeniería UNAM

Abstract

The constantly growing of the power system’s infrastructure as a response to the development of different economics sectors (industry, transport, trading, among others), implying the necessity of guaranty the reliability in operation of power system in the face of natural phenomenoms or technical – operatives, avoiding outages and blackouts. Due to the fact that these can cause a hard impact to the economy of a country. For this reason, the industrial sector has focused hard efforts in the development of technology and systems more efficient, which allow a real time monitoring of power systems, giving advantages in reliability and energy quality. One of the available solutions proposed currently are the systems of synchrophasors measurement systems, composed by Phasorial Unit Systems (PMUs) distributed throughout of power systems supplying the measurements of voltage, current, frequency and the frequency’s derivative, among others; Phasorial Data concentrators (PDCs) used to correlate the measurements through a time stamp to accumulate and implement applications online or offline afterwards. The present investigation proposes the implementation of a monitoring system in real time in a grid of test of laboratory based in synchrophasorial measurements. This system consists in the installation of different kinds of PMUs, these transmit information to a PDC equipment denominated PDC UD-UNAM, through a Local Area Network (LAN) under TCP/IP protocol. With all the information centralized was developed an application in LabVIEW® to visualize the network test’s state. The processed information is registered in a storage system, which allows consult historic dates of electrical variables. On one hand, the validation of this monitoring system was realized in the grid of test of the electronic of power laboratory of Engineering Institute of National Autonomous University of Mexico (II-UNAM). On the other hand, was developed a state estimation using the PDC UD-UNAM database through a cooperation with a doctoral thesis in the II-UNAM. Finally, were designed two guides of laboratory using equipment and the laboratory of electric machines of the District University Francisco Jose de Caldas, in order to promote the using and future applications of synchrophasor technology in the investigations of the same university.
