“Diseño, Instalación y Operación del Sistema de Control de Velocidad para las Unidades a Vapor Tv-2 y Tv-3 de la Central Térmica Ing. Gonzalo Zevallos”

Abstract

At the Gonzalo Cevallos power plant, older systems needed manual functions for startup, increase and decrease of load, machine stop, etc. it was difficult for operating personnel. Spare parts for these systems were very costly because they were made to order. The manufacturer no longer had experienced technical staff for maintenance of the different systems. Therefore, it was necessary to implement a new system of control and charging speed turbines. The speed control system and the load are to ensure that the speed of the turbine generator can be automatically kept constant and can be adjusted during operation after synchronization. To this effect, the purpose of the project was to modernize these systems Mechanical-Hydraulic MHI (Mitsubishi Heavy Industries) by an electro-hydraulic system. The new system focuses on Allen-Bradley ControlLogix controller type mark, based on the universal concept of control and respecting the philosophy of the manufacturer. It also is designed to receive commands via a Human Machine Interface (HMI). Finally able to achieve a more reliable and secure in the transient responses caused by faults in the electrical system operation, obtaining information for operational analysis and ease of maintenance by parameterization to vary the set point or block unwanted shots.
