Embodiment 1

[0062] A schematic flow chart of an operation and maintenance system master-substation interaction method provided by the present invention is as follows: figure 1 shown, including:

[0063] Step 1: When the master station receives one or more requests for obtaining operation and maintenance signals sent by the requesting sub-stations, according to the pre-generated forwarding table, obtain the signal-providing sub-stations corresponding to each request;

[0064] Step 2: The master station feeds back the operation and maintenance signal obtained from the signal providing sub-station to the corresponding request initiating sub-station;

[0065] Wherein, the forwarding table includes a signal list selected according to the substation-wide configuration description file sent by the sub-station.

[0066] Specifically, the process of the interaction method between the master and substations of the operation and maintenance system includes:

[0067] Step 101: The operation and mai...

Embodiment 2

[0100] A specific embodiment of the master-substation interaction method of the operation and maintenance system is given below.

[0101] The secondary equipment operation and maintenance system is an application system that provides inspection personnel with monitoring the operation status of the secondary system of the smart substation, and is deployed in the security zone II. The operation and maintenance system consists of two parts: the operation and maintenance sub-station and the operation and maintenance main station. The sub-station is responsible for the monitoring in the substation and provides technical means for maintenance in the station for the on-duty personnel or operation and maintenance personnel. The main station is deployed in the operation and inspection department to provide remote centralized The monitoring function supports operation and maintenance management. The monitoring content includes power grid operation status information, secondary equipment...

Embodiment 3

[0109] Based on the same inventive idea, the present invention also provides a master-substation interaction system of the operation and maintenance system. Since the principle of these devices to solve technical problems is similar to the interaction method of the master-substation of the operation and maintenance system, the repetition will not be repeated.

[0110] The basic structure diagram of the system is shown in Figure 7 shown, including:

[0111] Provide substation acquisition module and signal acquisition feedback module;

[0112] Wherein, a substation obtaining module is provided, which is used for obtaining the signal providing substation corresponding to each request according to the pre-generated forwarding table when the main station receives the request for obtaining the operation and maintenance signal sent by one or more substations;

[0113] The signal acquisition feedback module is used to control the main station to feed back the operation and maintenan...

Abstract

The invention provides an interaction method and system for a master station and sub-stations of an operation and maintenance system. The method includes the following steps: when the master station receives one or more requests for obtaining operation and maintenance signals sent by a request initiation sub-station, acquiring a signal providing sub-station respectively corresponding to each request according to a pre-generated forwarding table; and enabling the master station to feed back the operation and maintenance signals acquired from the signal providing sub-station to the correspondingrequest initiation sub-station, wherein the forwarding table includes a list of signals selected according to a transformer substation total station configuration description file sent from the sub-station. By adopting the method, the communication with the master station and the sub-stations of the system does not need to select a signal telecontrol data communication gateway forwarding table, artificial peer-to-peer is also not required between the master station and the sub-stations, the debugging efficiency that the operation and maintenance sub-stations access the master station can be greatly improved, and a plug and play function of the operation and maintenance system can be realized.

Description

technical field [0001] The invention belongs to the technical field of substation automation systems, and in particular relates to a master-substation interaction method and system of an operation and maintenance system. Background technique [0002] Since the large-scale construction of smart substations, the operation and maintenance department of secondary equipment in substations will be under enormous pressure on operation and maintenance. In this case, the regular inspection mode cannot meet the needs of intelligent equipment operation and maintenance, and the secondary equipment operation and maintenance system is established to realize the remote operation and maintenance of secondary equipment. The secondary equipment operation and maintenance system monitors the operation status of the smart equipment in real time, analyzes the health status and fault conditions of the equipment, and uploads the operation status information of the smart equipment to the remote oper...
