Ajuste y validación de funciones complementarias en voltaje, frecuencia y corriente de las protecciones SIEMENS IED’S 7SJ85 y 7SA86

Abstract

This work develops and validates a technical guide for the parameterization of Siemens 7SA86 and 7SJ85 intelligent electronic devices (IEDs) in distributed generation environments. The methodology, based on applied research, defines adjustment criteria for complementary protection functions according to international standards and IEEE standards, considering actual electrical system conditions. Through simulations in DIgSILENT PowerFactory, adjustment values and operating times were determined and validated, then implemented in equipment at the electrical protection laboratory of the Salesian Polytechnic University. Practical verification with OMICRON’s CMC 356 equipment confirmed the reliability of the proposed parameters and provides a replicable guide for the validation of these protection functions.
