Embodiment 1

[0044] refer to figure 1 As shown, the telecontrol device point-to-point system of the present invention includes a client point-to-point module (client), a telecontrol device (telecontroller) and a plurality of protection measurement and control device point-to-point modules (measurement and control protection devices); the client point-to-point The module is connected to the point-to-point module of each protection measurement and control device through the telecontrol device;

[0045] Client-to-peer modules include:

[0046] The real-time data acquisition unit acquires the data of the measuring points of each protection measurement and control device in the real-time database of the telecontrol device;

[0047] The communication enable command sending unit sends the communication transmission enable command to the protection measurement and control device through the telecontrol device, so that the writing function of the communication transmission enable point of the prot...

Embodiment 2

[0057] In this embodiment, after the remote control device obtains the measuring point signal message returned by the protection measurement and control device: for the state type measuring point, the remote control device updates the real-time database according to the measuring point data in the measuring point signal message, and sends the measuring point signal The message is forwarded to the point-to-point module of the client; for the measuring point, the telecontrol device only updates the real-time database according to the measuring point data in the measuring point signal message, and does not forward the measuring point signal message. This real-time database refreshing and forwarding mechanism is because the protection measurement and control device in normal operation often has small fluctuations, and forwarding reports every time fluctuations will cause a large number of useless reports and affect normal communication.

[0058] Correspondingly, when the data analy...

Embodiment 3

[0064] In this embodiment, the remote control device automatic point-to-point method based on the aforementioned remote control device point-to-point system includes the following steps:

[0065] S1, confirm that the communication between the client, the telecontrol device and the protection measurement and control device is normal;

[0066] S2, the client point module obtains the measurement point data of the protection measurement and control device in the real-time database of the telecontrol device;

[0067] S3, the point-to-point module of the client sends a communication transmission enable command to each protection measurement and control device through the telecontrol device; the corresponding protection measurement and control device point-to-point module makes the protection measurement and control device enter the communication transmission enabling state according to the communication transmission enabling command;

[0068] S4. The point-to-point module of the cli...

Abstract

The invention discloses a telecontrol device comparison system and an automatic comparison method. The telecontrol device comparison system comprises a client comparison module, a telecontrol device and a plurality of protection and monitoring device comparison devices; and the client comparison module is connected with each protection and monitoring device comparison device through the telecontrol device. When in comparison, the client comparison module controls the value writing function of a communication transmission enabling point of an enabling protection and monitoring device through the telecontrol device, so as to write a measuring point FCDA index message and a test value to the communication transmission enabling point; the protection and monitoring device generates a measuringpoint signal message and sends the message to the telecontrol device, the telecontrol device updates the measuring point data in a real-time database according to the measuring point signal message, the measuring point signal message is transferred to the client comparison module according to the measuring point type, the client comparison module compares the current real-time measuring point datawith the measuring point data in a test value writing instruction, so as to judge whether comparison success of each measuring point is achieved or not and output a comparison result message. According to the comparison system and the comparison method in the invention, comparison between a telecontrol device SCD model and an associated protection and monitoring device ICD model can be achieved,and the comparison efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electric power system automation, in particular to a telecontrol device point-to-point system and an automatic point-to-point method. Background technique [0002] IEC61850 has been widely used in the field of power system automation, in which the remote control device is used as a connecting layer, and several protection measurement and control devices are associated with the lower layer. Each protection measurement and control device has an ICD (IED Capability Description) file, and the telecontrol device has an SCD (Substation Configuration Description) model, which manages the ICD models of several protection measurement and control devices (the CID model is formed after SCD configuration). The telecontrol device converts the SCD model into a real-time database structure, and communicates with the protection measurement and control device through the 61850 protocol. When the ICD model of a single pro...
