Abstract

Se proporciona un sistema y método para monitorear la rotación de un rotor generador y calcular un ángulo de energía utilizando un monitor de desplazamiento de rotor óptico. El monitor utiliza un haz de luz dirigido hacia el rotor para detectar una marca en el mismo, y genera un pulso eléctrico cuando se detecta la marca. El tiempo entre el pulso y un punto de referencia (tal como un cruce de curvas en punto cero) de la forma de onda de señal desde las terminales del generador se utiliza para calcular el ángulo de energía del generador El sistema es adaptable en la medida en que toma en consideración marcas nuevas en el rotor. El sistema se puede conectar a una red de manera que los ángulos de energía de diversos generadores en la red eléctrica se pueden comparar. El sistema e puede conectar adicionalmente a una fuente de tiempo común de manera que se pueda aplicar una marca de tiempo a los ángulos de energía desde diversos generadores.A system and method is provided to monitor the rotation of a generator rotor and calculate an energy angle using an optical rotor displacement monitor. The monitor uses a beam of light directed towards the rotor to detect a mark on it, and generates an electric pulse when the mark is detected. The time between the pulse and a reference point (such as a crossing of zero-point curves) of the signal waveform from the generator terminals is used to calculate the generator energy angle. The system is customizable to the extent. in that it takes into account new marks on the rotor. The system can be connected to a network so that the energy angles of various generators in the power grid can be compared. The system e can additionally connect to a common time source so that a time stamp can be applied to the energy angles from various generators.
