Medición de la frecuencia frente a variaciones de carga utilizando un prototipo de generación

In the research carried out, the basics of Powerfrequency control in a synchronous generator were addressed in order to know the behavior of the frequency before load variations of the generation system in real time; By using these principles, a visualization, monitoring and data acquisition module was developed for the measurement of frequency, speed and voltage, using an Arduino Nano board and the Nextion screen to evaluate the effects produced in the system. To do this, the voltage wave behavior was studied to determine the duration of each cycle, by using a reducing transformer and an electronic circuit which allows converting the sine wave into a square wave capable of being processed, allowing to obtain the duration time of each cycle and through the crossings by zero, obtain the linear graph of the frequency and in turn measure the duration time of the transients. Because the frequency varies with any disturbance of the load, it was necessary to make a practice model to understand the variables that are immersed in the control P.F. that is why in the experimental stage when injecting a resistive load in the generating group of the LabVolt module it was found that the frequency decreases by 60% of its nominal value and stabilizes in a time of 10 seconds in said value, due to the load increase directly affecting the frequency.
