Diseño y construcción de un control electrónico de carga para regular la frecuencia en una micro-central hidroeléctrica

Abstract

In this work, it is presented the design, construction and implementation of an Electronic Load Controller to regulate the frequency and an Automatic Voltage Regulator to regulate the voltage of a Micro-Hydroelectric Plant by keeping these variables into their constant nominal values when there are load variations caused by the customer of the system. Also, it is implemented a supervision and alarm system which allows identifying the main dangers or possible failure events considering all the time the current normative of the Consejo Nacional de Electricidad about the Quality of the Distribution´s Electric Service and the Procedures of Operation and Delivery. The hardware is formed by sensors of frequency, voltage, current and power factor with their respective reconditioning circuits. Also it has the protection and handling elements needed to protect the Micro-Hydroelectric Plant. The frequency and voltage regulation is done through PI digital controllers designed based in the mathematic models obtained and proved with the experimental data from the plants of frequency and voltage.
