Method and system for automatically identifying bypass replacement state on basis of GOOSE information

Abstract

The invention provides a method for automatically identifying bypass replacement state on the basis of GOOSE information. The method comprises the following steps of: step one, acquiring real-time data information of a main connecting wire and a bypass of a safety automatic device through a GOOSE network; step two, according to the real-time data information, judging whether a circuit / transformeris in the bypass replacement state; and step three, when the circuit / transformer is in the bypass replacement state, setting the working mode of the safety automatic device as a bypass replacement state mode. The invention also provides a system for automatically identifying the bypass replacement state on the basis of the GOOSE information. Through the technique in the invention, a digitized transformer safety automatic device can realize the automatic identification of the bypass replacement state, reduce the workload of site operation, and avoid risks caused by misoperation and operation forgetting, so the time for inconsistent operation is theoretically close to 0, and the running reliability of the device is improved.

Description

technical field [0001] The invention relates to a method and system for automatically identifying the state of a bypass generation based on GOOSE information, belonging to the technical field of electric power systems and automation. Background technique [0002] During the operation of the power system, the circuit breaker of the line / transformer needs to be repaired in a timely manner. At this time, the line / transformer needs to be hung on the bypass bus to achieve the purpose of no power failure of the line / transformer, such as figure 1 as shown, figure 1 It is a schematic diagram of the power supply line structure of the power system. When the main power supply line is overhauled, it is necessary to supply power from the bypass to the bypass bus, and at the same time switch the line / transformer to be powered by the bypass bus. [0003] When the safety automatic device is running, it is necessary to judge the bypass state of the line / transformer. When it is in the bypass...

Problems solved by technology

[0005] The following disadvantages are difficult to overcome with the use of "bypass pressure plate": ①Because manual operation is required for the bypass pressure plate, there must be inconsistencies between the operation and the actual operation during operation. switch operation, or the operation operator completes the switching operation first, and then puts in / out the pressure plate; ②There is a risk that the on-site operation operator forgets to operate, if this happens, it will lead to long-term inconsistency, and the reliability of the safety device Low
