Brazilian Utilities experience in Acceptance, Commissioning and Maintenance Testing Techniques for Protection and Automation Systems based in IEC-61850

摘要

The paper will address the changes and new practices from the point of view of electricutilities, with respect to testing procedures in various stages of implementing protection andautomation systems based on IEC-61850. This work is the result of the contributions made bythe Brazilian mirror group of WG B5.45: Acceptance, Commissioning and Field TestingTechniques for Protection and Automation Systems.It will examine various aspects of the conformance tests (including interoperability tests),homologation or qualification tests, factory acceptance tests (FAT including interoperabilitytests), site acceptance tests or commissioning, and maintenance tests.Also presented will be a flowchart typical of the practices adopted in various stagesconsidering: How the tests are defined, who defines the tests, who validates the testsprocedures, who executes the tests, how are the tests documented, and who validates theresults of the tests.In addition to the theoretical aspects, there will also be presented practical difficultiesencountered by companies to adequately perform in each step, and the strategies thatcompanies adopt to overcome problems and achieve deadlines and costs, and guarantee safetyand quality from the point of view of operating and maintenance of protection and automationsystems. Also management and integration of legacy systems will be presented especiallyconsidering the difficulty of the execution of tests.
