“…Extensive research on the topic of automatic calculation of protection settings has been undertaken [8], which includes the use of topological analysis [9][10][11], optimisation theory [12,13] and artificial intelligence [8,14,15]. However, such systems performing automatic protection setting and coordination are not particularly suitable for settings validation, even though they provide very relevant functionality.…”

The reliable operation of protection systems depends on the correct settings of protective devices. The complexity of power networks and the large number of protection setting parameters make it extremely challenging to comprehensively validate the settings. This paper presents the design of a hybrid Rule-Based (RB) and Model-Based (MB) intelligent system termed Power system Protection Smart Tool (PPST), which is proposed as a solution for addressing the challenges associated with protection settings validation and performance checking. The RB element evaluates the settings using rules extracted from experts' knowledge and utility setting policies, while the MB element automatically interfaces with DIgSILENT PowerFactory to populate power network and protection system models to simulate and check the actual performance of the protection system under a variety of operational contexts. A case study is presented to demonstrate the operation of PPST, which shows that it is capable of effectively conducting the protection settings validation and performance checking task.

The work presented in this chapter addresses the problems encountered by the conventional digital distance relay used for the protection of transmission lines fed from one end. To observe its behavior during a high resistance single line-to-ground fault, a laboratory prototype of a three-phase transmission line using equivalent power system components has been developed by the authors. Thereafter, a new digital distance relaying algorithm is presented for the compensation of errors produced by the conventional digital distance relay during a high resistance single line-to-ground fault. The proposed algorithm is based on digital computation of impedance, which uses symmetrical components of three-phase currents and voltages measured at the local end only. The proposed algorithm has been tested using MATLAB/SIMULINK (The MathWorks, Natick, Massachusetts, USA) software for a single line-to-ground fault considering wide variations in fault resistance, fault location, power factor, and short-circuit capacity of the source.

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.
