A Procedure To automate the assessment of generator protection

Abstract The evaluation of protection performance after a generator shutdown is mandatory to assess if all automatic actions resulted in system security and safety to its users. Nowadays, however, the number of digital fault recorders and protection devices with oscillographic functionalities has intensely increased, making traditional manual analysis excessively time consuming. In this context, the contribution of this work is to propose a procedure to automate the evaluation of generating units’ protection, making it possible for the engineers to focus on the most important data. The proposed procedure was evaluated through the development of a prototype designed using the multi-agent paradigm, taking advantage of its main computational benefits. The implemented prototype generated correct assessments for a large set of real disturbances, proving to be a very efficient and accurate tool for assessment and decision support to operators.
