Description

Technical Field

[0002] A microprocessor-based relay protection device is a comprehensive relay protection device that integrates both inverse-time and definite-time relay protection. Relay protection devices are often used to provide safety protection for power equipment, such as transformers, motors, generators, and transmission lines in power distribution systems, against short circuits and ground faults. Relay protection devices primarily utilize changes in electrical quantities caused by short circuits or abnormal conditions within power system components to trigger relay protection. Other physical quantities, such as the large amounts of gas and oil flow or increased oil pressure generated by faults within transformer tanks, are also used. In most cases, regardless of the physical quantity being detected, a relay protection device consists of a measurement section, a logic section, and an execution section. Parameters in power system operation differ significantly between normal operation and fault conditions. Relay protection devices utilize these parameter changes to detect and assess the nature and extent of power system faults, enabling them to respond and address them accordingly.
