Diseño y simulación de un sistema de protección para generación con los equipos SEL-700G, 751, RTU RTAC SEL-3530 Y CMC 356 integrados en un sistema de monitoreo SCADA

Abstract

The technical project focused on the simulation of a generation SEP. With the IEC 61850 communication protocol, the same one that was integrated into a SCADA environment, which showed us the generation SEP digitally. Where several practices were carried out to validate the settings loaded in the protection system, which are applied in a generation SEP. The settings set in the 751 meters were focused on measurement and the 700G meter was focused on SEP protection. The proposed simulation practices were designed under the IEEE standard, which requires the LAN _ IEC 61850 communication protocol, the same one that allowed us to integrate the IEDs 751 and 700G to the RTU_RTAC 3530, through the GOOSE messaging protocol, allowing the exchange of data between the IEDs and the RTU. Within the structure of established two types of data that were treated, digital type as buffer and analog without buffer, they were declared in the Architect software, and defined as type variables: ST = status data, MX = measured data, CO = check data. In the same way, the RTU was parameterized with the MMS protocol, through logical control and protection nodes with the type variables: CF = MX, FC=ST. Through this parameterization we managed to modulate the different proposed practices, with the existing equipment in the electrical protection laboratory, this implementation allowed us to know the functionality of the IEC 61850 protocol, as well as the GOOSE and MMS connection that they use as a LAN connection to exchange data between the IEDs, the RTU and the SCADA. In the simulation it was possible to simulate faults that were adjusted in the IEDs 751 and 700G as the protection: 50P, 50N, 51P, 51N, 87, 27, 59…etc.
