Embodiment 1

[0034] Such as figure 1 As shown, a multi-interval integrated digital measurement and control device 10 includes: HSR (High-availability Seamless Redundancy, high-speed reliable seamless redundancy) interface plug-in 110, optical communication plug-in 210, DSP plug-in 120, CPU plug-in 130, HTM bus 180 And controller local area network (CAN) bus 190; Described optical communication plug-in 210, DSP plug-in 120, CPU plug-in 130 are all connected with HTM bus 180 and / or CAN bus 190 of completing data transmission; Wherein,

[0035] HSR interface plug-in, used to receive multiple intervals of HSR ring network data, decode the HSR ring network data into IEC-61850 standard 9-2 sampling data, GOOSE input data and forward it to the optical communication plug-in; receive data from the optical communication plug-in Control commands and send them to corresponding intervals;

[0036] Specifically, the HSR interface plug-in 110 can use an optical fiber interface to access the process laye...

Embodiment 2

[0061] A multi-interval integrated digital measurement and control device switching method between master and backup, such as figure 2 shown, including the following steps:

[0062] The multi-interval integrated measurement and control device in the station adopts dual configuration and parallel monitoring. Two measurement and control devices are configured as the main and standby machines, and the main and standby machines are connected to each other to exchange their respective operating states;

[0063] Multi-interval integrated measurement and control devices realize dual data collection through the process layer communication of the HSR interface plug-in and the station control layer communication of the CPU plug-in. The principle of dual data processing is that the GOOSE signal received by the station control layer is the main criterion, and the GOOSE signal received by the process layer is used as the auxiliary criterion;

[0064] The signal of dual data collection re...

Abstract

The invention discloses a multi-interval integrated digital measurement and control device and a main and standby machine switching method thereof. The multi-interval integrated digital measurement and control device comprises an HSR interface plug-in, an optical communication plug-in, a DSP plug-in, a CPU plug-in, an HTM bus and a CAN bus. The optical communication plug-in, the DSP plug-in and the CPU plug-in are all connected with the HTM bus and / or the CAN bus which completes data transmission, and the heartbeat signals between the mutual standby measurement and control sub-machines are used for the diagnosis switching of a main machine and a standby machine. According to the invention, the substation multi-interval measurement control function supporting the HSR looped network data access and data forwarding can be realized, and the substation automatic operation and maintenance convenience, the operation safety and the economic reliability are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of measurement and control of digital substations, and in particular relates to a multi-interval integrated digital measurement and control device and a method for switching main and standby machines. Background technique [0002] With the construction of the power grid and the new construction, expansion, and transformation of substations, especially the construction of the third-generation smart substations, the requirements for the integration of power devices are getting higher and higher. At present, the measurement and control devices of the power system are mostly configured separately according to electrical intervals. In this way, not only a large space is required to place such a large number of devices, but also the economic cost is high. However, at present, there is no measurement and control device in the industry that integrates measurement and control functions of multiple intervals. Multi-i...
