Embodiment Construction

[0030] Such as figure 1 As shown, the present invention provides an embedded device for real-time monitoring of substation relay protection and fault recording equipment, including: a serial port card 1, a network port card 2, a core board 3, and a common backboard 5. These boards are accommodated in the housing 4 of the embedded device.

[0031] The serial port board 1 and the network port board 2 are pluggable and provide multiple expansion slots. The common backplane 5 adopts the PCI bus mode. The serial port card 1, the network port card 2 and the core board 3 are inserted into the common backplane 5 in the form of a bus. The core board 3 is provided with a processor to analyze and manage the obtained information data.

[0032] For example, each serial port card 1 can be configured with 8 RS485 / RS232 serial ports, and RS485 and RS232 can be switched through the dial; each network port card 2 can be configured with three 10M / 100M independent network ports; the core board...

Abstract

The invention discloses an embedded device for monitoring relay protection and a fault recording device of a transformer substation in real time, and also provides an information interconnection system suitable for the embedded device mentioned above. The embedded device is connected with a protection device supporting a serial port through a serial port card; the protection device supporting thenetwork port and a fault recording device at a site at the level and a protection device at a site at the next level are connected through a network port card and perform interconnection and intercommunication of information with a main station system at the previous level; a processor of a core board is configured to perform analysis and management of the obtained information data; and the serialport card, the network port card and the core board are inserted into a common back board in a bus mode. The embedded device is simple in structure, low in cost, low in power consumption, convenientto install, simple to operate and high in expandability, can adapt protection devices and fault recording devices with different voltage levels, different types and different factories which have beeninstalled in the transformer substation and can provide system support for the remote maintenance, fault intelligent analysis and mobile operation of the protection devices.

Description

technical field [0001] The invention relates to an embedded device for real-time monitoring of substation relay protection and fault recording equipment. Background technique [0002] Relay protection devices are important equipment related to the safe and stable operation of the power grid, and are an indispensable and important part of the power system. Therefore, the daily management of relay protection devices has become one of the reusable tasks of the power system. Due to the wide variety of relay protection devices and the variety of manufacturers and models, great pressure has been placed on device management. For example, in addition to meeting the consistency requirements in terms of functions, different manufacturers have great differences in internal principles, fixed value management, and communication transmission. Moreover, the manufacturers themselves also have devices of different periods, and the technical means and software versions will also be different...
