Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] like figure 1 As shown, it is the communication network interface diagram of the relay protection and measurement comprehensive device integrating multiple communication interfaces of the present invention. The microprocessor in the figure is a 32-bit microprocessor LPC2292 of Philips, which integrates a 16Byte transceiver FIFO inside (First-in-first-out register) serial port UART1 and UART2, also integrates CAN controller 1 and CAN controller 2 with powerful acceptance filtering function. The comprehensive protection device shown in the figure has three types of interfaces, and each type of interface includes two i...

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 ...
