To achieve the timely response for the potential disturbances in protection relay systems, this paper establishes anomaly detection method for warning and analyzing such disturbances.
Protective relay
OverviewRelays by functionsOperation principlesTypes according to constructionPower source
The various protective functions available on a given relay are denoted by standard ANSI device numbers. For example, a relay including function 51 would be a timed overcurrent protective relay. An overcurrent relay is a type of protective relay which operates when the load current exceeds a pickup value. It is of two types: instantaneous over current (IOC) relay and definite time overcurrent (DTOC) relay.
Design of an adaptive identification method for faulty operating states
Traditional relay protection systems are designed based on electrical principles and mechanical transmission. Although they provide basic protection functions, they suffer from
Power Consumption-based Anomaly Detection for Relay Protection
As a critical monitoring and control device, the protection relay helps improve safety, reliability, and simplify of the smarter grid. However, due to the lack of effective anomaly detection and protection
Protective Relays: Types, Working Principle & Uses
What Is a Protective Relay? A protective relay is a control and measurement device used in power systems to detect faults, unsafe operating conditions, or abnormal electrical behavior.
