automated maintenance of protective relays12099

Project TitleProject Area of Specialization Electrical/Electronic EngineeringProject Summary

Power systems rely on protective relays to monitor critical electrical quantities and initiate emergency shutdown on the detection of out-of-limit conditions.

Instrument transformers, such as potential transformers (PT) and current transformers (CT), reduce the power system currents and voltages to levels usable by protective relays and other control and metering devices.

Instrument transformers for metering purposes must have a high degree of accuracy to ensure precise billing while those used for protection must react correctly during fault events.

Protective relays are an essential component of the protection system of a power system; they monitor critical electrical quantities and initiate emergency shutdown when they detect out-of-limit conditions.

The relays must correctly detect abnormal conditions, shut down the appropriate equipment, and must not operate incorrectly or unnecessarily.

All relay settings must be kept up to date and any changes must be documented and verified.

Project Objectives

To develop a framework for automated testing of protection devices i.e., protective relays, current transformers (CT) and potential transformers (PT) in real-time using multiple sensor inputs.

An algorithm will be developed that detects the fault and identifies the required corrective action as per the severity of the fault.

Project Implementation Method

Primary automated maintenance procedures required for this challenge are verifying relay settings,

relay analog to digital inputs, and PT and CT signals at the relay (magnitude and phasing).
