Use of graph theory simplifies representation of complex bus arrangements in power system stations. This paper presents a new method, based upon graph theory, for selecting bus protection zones in microprocessor-based relays. We use a typical bus arr

A comprehensive list of nondirectional overcurrent relays would include thermal overload, inverse-time, definite time, and instantaneous relays. The list could be further classified by operating quantities including individual phase, residual, and ne

This paper discusses the goals of routine maintenance testing for protective relays. The paper advances a Markov probability model that predicts the optimum test interval for protective relays with and without self-testing capabilities. The model use

Negative-sequence overcurrent elements do not respond to balanced load and can thus be set to operate faster and more sensitively than phase overcurrent elements for phase-to-phase faults. It is demonstrated that on a radial distribution system negat

To date, synchronized phasor measurements have been used mainly for power system model validation, post-event analysis, real-time display, and other similar activities. However, synchrophasors have a greater potential than monitoring and visualizatio

Increasing demands on electricity supply, with the need for system economic optimization and power system growth limitations, have a significant impact on power system reliability. When the system operates in extreme conditions, load shedding, genera

Traditional protective equipment does not adapt readily to distribution system reconfiguration. If new settings are needed they have to be manually changed: there are no settings in reserve. The time to make or enter and test new settings slows down

The authors identify filtering requirements or criteria for different relays. They limit the discussion to relays needing precise measurements of the system-frequency component of the signals, such as distance relays. Many different filtering methods
