Diseño e implementación del TMPG, STDI y un sistema automatizado para el control y monitoreo remoto de cargas de la red eléctrica del laboratorio de producción industrial.

Abstract

The Panel of Measuring and General Protection(TMGP) was designed and implemented, as well as the Sub Board of Internal Distribution (STID) and an automated system for the remote control and monitoring of loads from the electric network of the Industrial Production Laboratory, Science Faculty, at Escuela Superior Politecnica de Chimborazo. For the design phases and system implementation the basis phases of the scientific method was taken into account. The design is formed by the electric network, a board which has a general breaker, a sequence phase sensor, that enables the system operation, but only when the sequence is correct (RST); in addition to a power meter which is responsible for electrical variables collecting information and sending them to a Programmable Logic Controller (PLC) which transmits in real time, using a wireless network communication protocol to the central computer enabling the control ON/OFF of the equipment. The human machine interface (HMI) developed in the LabView software contains the absolute control of the board, produces consumer reports, allows the visualization of electrical variables and generates alarm messages from unexpected system failures. Additionally, there is the generation of alarms ant the control of the equipment by using text messages. A study was carried out and the electrical system and automation were compared with the previous state of the laboratory, with the results the lack of main elements of an optimal electrical installation and based in the Ecuadorian Regulations Work Safety against the risks in installations of Electric Energy, it was concluded that, there was a level of maximum risk and a priority of critical intervention of level I, besides the absence of alarms and monitoring of electrical variables. With the implemented system the efficiency achieved a 100% at the times of data collection and generation of alarms to avoid serious damage to the Laboratory Industrial Production equipment. It is recommended that the personnel, responsible for the Laboratory of Industrial Production should not manipulate the physical board directly, but only through the mainframe to safeguard their physical integrity.
