Inventor: BRAVO DE LAS CASAS MARTA
IPC: H02H3/38
Filed: 1988-04-07
Abstract: Esta invención se relaciona con la protección y automatización de sistemas electroenergéticos y en particular con la protección de distancia polifásica. El objetivo de la invención es lograr el esquema electrónico de manera simplificada, de un órgano que discrimina los diez tipos de cortocircuitos presentes en una línea, y realice las conmutaciones necesarias para que a la unidad de medida lleguen las senales correspondientes al tipo de cortocircuito que ocurrió. La esencia de la invención consiste en lo siguiente: se conocen teóricamente las características técnicas del órgano, el cual debe discriminar si el cortocircuito involucra tierra o no, y a partir de ésto y por medio de la comparación de fase de las senales de entrada, corriente de secuencia positiva, negativa y cero, con lo cual se decide el tipo de cortocircuito; se anade el diseno de todos los circuitos electrónicos que sean capaces de realizar la función deseada, así como la formación de las senales de entrada al mismo. Todos los circuitos fueron disenados con amplificadores operacionales, compuertas lógicas, monoestables y transistores de efecto de campo. La invención puede utilizarse como base para construir relés de distancia polifásicos, utilizados en la protección de los sistemas electroenergéticos, los cuales presentan una serie de ventajas sobre la versión electromagnética. Este a su vez tiene la ventaja de que conjuntamente con él se puede utilizar una unidad de medida con altos requerimientos en lo que respecta a los procesos transitorios y además evita la carrera de contactos y la falsa medición de la impedancia de los relés ordinarios y conmutados.
