Description
Technical Field
The invention relates to the technical field of power system automation, in particular to a method and a device for quickly positioning information errors of a distributed control system and a readable storage medium.
Background
Substation automation systems can be classified into centralized and distributed types according to structural form:
the centralized type is that a front-end processor is used for carrying out data exchange work on the acquisition and control equipment, and the information is transmitted to an upper computer. The front-end processor in such a configuration has a drawback of low response speed and poor reliability, because it needs to process a huge amount of data. Once the front-end processor fails, the whole substation automation system is affected, other units depending on the front-end processor cannot work, and risks are concentrated.
The distributed mode is a mode of combining three layers of structures: the 1 st layer is a monitoring layer and is used for monitoring, managing and controlling subordinate transformer substations and the like by a master station; the layer 2 is a communication processing layer and is used as an intermediate layer and is responsible for connecting the data of the main station and the substation and carrying out communication management, and meanwhile, certain processing is carried out on messages sent by the substation and sent by the main station, so that the data exchange efficiency is enhanced; and the 3 rd layer is a data acquisition layer and is responsible for data acquisition work of all equipment of the transformer substation, and the acquired data information is packaged and delivered to the communication management layer. By dispersing the risk of the whole system through the layered structure, the system can not cause all the equipment to fail due to the failure of the communication layer. Distributed control is a system architecture that is widely adopted by substation automation systems today.
Major errors in distributed control systems include: communication errors, which result in channel interruption due to configuration errors or damage of communication software or hardware, eventually cause data interaction failures. The association error generally occurs when the remote control point is configured to the wrong remote signaling point, and once the master station issues a remote control command, the device in the substation may malfunction. The error of the leakage point is possible to occur on the 1 and 2 layers, once the error of the leakage point occurs, the data acquisition point position cannot be aligned, and the data received by the master station finally is incomplete, so that the data monitoring effect is influenced.
In the prior art, a chinese patent publication No. CN107566171A discloses a hierarchical error location method for a publish/subscribe distributed system in 2018, 1 month and 9 months, and performs online error location when an error occurs during operation of the publish/subscribe distributed system. The method can automatically generate an error propagation model of the system according to the application logic relationship among the components during the operation of the system, decompose the error propagation model into error propagation models on a single component and across components, and implement a layered error positioning scheme that the single component uses the single component error propagation model to position and then the server uses the across component error model to position. Although the scheme realizes the layered error positioning, the scheme is applied to a web network system and is not suitable for an automation system of a transformer substation.
