Avanços no desenvolvimento de projetos de proteção, automação e controle (PAC) de subestações a partir da aplicação do conceito de Engineering Information Modeling (EIM) pelo software Engineering Base

Abstract

In the context of the implementation of Smart Grids and the challenge of network interoperability, it is proposed in this work the register of the productivity improvements resulting from the use of the Engineering Base (EB) software with the Engineering Information Modeling (EIM) methodology for substations Protection, Automation and Control (PAC) design. In this way, an approach is developed in this work through a case study based on the arrangement of a database in the engineering platform for PAC design of a typical substation. The benefits that come from using the EIM concept for data modeling are demonstrated. For this purpose, the automatisms developed in the computational tool are presented, using the VBA (Visual Basic for Applications) programming language and the software's metalanguage. The possibilities of automatic execution of stages of the electrical design stand out, with the development of deliverables, and the minimization of the effort required for certain tasks. The defense of the technological evolution provided by the engineering and programming platform is carried out through a case study. The proposal for a typical case consisted of a 69 kV line connection problem in a typical substation. For the arrangement of the 69 kV sector of the substation, a main and transfer bus configuration was considered. The proposed system consists of 01 (one) autonomous unit containing 02 (two) Protection and Control Intelligent Electronic Devices (IED) for the event. The chosen IEDs are from the SIPROTEC 7SA86 line, from Siemens, which are digital distance protection relays specifically designed for line protection. Real models of outdoor equipment and devices were analyzed for the elaboration of the typical substation event PAC design. Indeed, the technical solutions related to the event are presented, through the PAC design deliverables. It is intended that these records prove the feasibility of using the Engineering Base to apply the EIM methodology. Adding to this, it is estimated that the developed automatisms qualify significant advances for the elaboration of PAC substation designs in an engineering platform
