“…In his findings, Sazali utilized the hypothesis approach which consisted of different combinations of pre-prepared simulated events. This approach is relatively similar to the modelbased approach that had been discussed by Mc Arthur et al [32]. However, the disadvantage of this approach is that the system requires an ideal protection system without any relay mal-operations.…”

“…É responsável por simular o raciocínio mais superficial no problema do diagnóstico ( [8], [9]). Sendo assim, consiste em verificar qual relé atuou; o estado das variáveis digitais de trip e partida das funções de proteção, das variáveis digitais de abertura do disjuntor e dos alarmes do relé; e as magnitudes das correntes nas três fases, fornecendo então um primeiro grupo de resultados para identificar o evento ocorrido.…”

It is important that electrical networks have high levels of reliability in order to maintain the ideal agility and maintenance for better functioning. This fact combined with the increasing amount of information available in modern digital relays advances the idea of implementing systems that assist achieve fast and correct decisions on the protection system functioning. The purpose of this project was to implement a system that responds in an automated manner to protectionrelated events in distribution substations, providing a quick and complete diagnosis. The work has two foci. The first is the communication system based on an IEC61850/OPC server and the process automation through a client program. The second is an expert system that analyzes protection-related events based on data collected from the relays. An important result was the possibility of generating a correct diagnosis based on different data sets. This is extremely important, since one cannot expect exactly the same set of information for analysis, which should not prevent the delivery of a diagnosis. This system was installed in a substation of Companhia Paulista de Força e Luz, a Brazilian power distribution utility.

“…A large number of proposed areas of application have been developed and applied in recent years. Generally, there are four main application categories: protection performance analysis [4]; protection setting, and coordination [2,[5][6][7][8]; fault identification and location [9,10]; and service restoration and remedial action [11,12].…”

“…However, the method can only be applied to transmission system and is constrained to distance protection settings. Reference [4] introduces an expert system that applies a frame-based inference mechanism to achieve an efficient integration of frames and rules. It could successfully carry out basic settings for distance and over-current protection but lacks many practical functions and is constrained to certain relay types.…”

Due to many developments taking place within the electricity supply industry, the network and its operation has grown ever more in recent years, which brings significant challenges for power system protection engineers. Apart from the significant efforts that are required to ensure that the protection setting process is effective, work also needs to be carried out to check the validity of the settings after initial calculation and application. However, solely relying on personnel and procedures to assess the validity of the protection relay setting files may occasionally result in a hidden error (or errors) remaining undetected until an in-service mal-operation event is experienced. This may bring significant consequences, in terms of economic costs, potential safety hazards and damage to the reputation of the utility company. This paper will present the initial research of making use of artificial intelligence technology (expert system) to help protection engineers validate the protection settings. Existing expert systems for protection settings applications will be reviewed and a new intelligent system that can open a setting file and interrogate the protection functions and settings in the file will be introduced. The advantages of this novel intelligent tool over existing protection setting expert systems will be discussed.Index Terms-Artificial intelligence, expert systems, power system, power system protection, power system relaying.
