Relay protection and measurement integrated apparatus with multiple communication interfaces integrated

Abstract

The invention provides a relay protection and measurement integrated device which integrates a plurality of communication interfaces, in order to solve the problem that the single-typed communication interface in the existing relay protection and measurement integrated device can not satisfy the networking requirements of different users and on different application occasions. The integrated device comprises a microprocessor, an RS-485 interface, a CAN bus interface and an Ethernet interface, wherein a UART serial port, an address bus, a data bus and a control bus are integrated in the microprocessor; the RS-485 interface, the CAN bus interface and the Ethernet interface are respectively connected with the microprocessor. The relay protection and measurement integrated device is provided with a plurality of communication interfaces, and has rich, diverse and flexible networking modes, thereby satisfying the networking requirements of different users and on different application occasions to the greatest extent.

Description

technical field [0001] The invention belongs to the field of power systems, in particular to a relay protection and measurement integrated device applied to power systems. Background technique [0002] In the electric power industry, relay protection and integrated measurement devices are important secondary equipment in the power system. Relay protection devices working in medium and low voltage power systems generally have measurement functions. Usually, such relay protection devices with both protection functions and measurement functions are called integrated relay protection and measurement devices, or comprehensive protection devices for short. It can respond to the faults and abnormal working conditions of electrical equipment, and automatically, quickly and selectively act on the circuit breaker to remove the faulty equipment from the system, so as to ensure that the non-faulty equipment continues to operate normally, limit the accident to a minimum, and improve the ...
