Description

Technical Field

[0001] The present invention relates to a method and device for maintaining dual-active models between a primary and a standby dispatching automation system, and belongs to the field of power dispatching automation. Background Art

[0002] The dispatching automation system is the core support system for power production dispatching. To enhance the disaster tolerance of the automation system, at present, power grids at all levels in China have generally built two sets of dispatching automation systems, namely, a primary dispatching system and a standby dispatching system. The standby dispatching system runs in parallel as the hot standby of the primary dispatching system. After the power grid model is maintained in the primary dispatching system, it is necessary to synchronize the power grid model data to the standby dispatching system in a timely manner to meet the requirement of model consistency between the primary and standby dispatching systems and avoid secondary maintenance of the model information in the standby dispatching system.

[0003] The current construction of the standby dispatching system can effectively improve the reliability of the dispatching automation system, but it can only achieve one-way maintenance and synchronization of the model and cannot achieve dual-active maintenance of the model.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a flowchart of the method of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and should not be used to limit the protection scope of the present invention.

[0023] A model dual-active maintenance method between a primary and standby dispatching automation system, comprising the following steps:

[0024] Step 1, in response to detecting that itself changes from the primary dispatcher to the standby dispatcher and there is model maintenance when itself is the primary dispatcher, send the model maintenance file to the current primary dispatcher;

[0025] Step 2, in response to detecting that itself changes from the standby dispatcher to the primary dispatcher and receiving the model maintenance file sent by the original primary dispatcher, perform model maintenance according to the model maintenance file.

[0026] The above method is applied to two sets of dispatching automation systems. When the primary and standby are switched, the original primary dispatcher sends the model maintenance file to the current primary dispatcher, realizing the dual-active maintenance of the primary and standby dispatcher models and improving the redundancy of the power dispatching system.

[0027] Define two sets of dispatching automation systems, A and B. Assume that originally A is the primary dispatcher and A enables the model maintenance function, and B is the standby dispatcher. When the primary and standby are switched, that is, A becomes the standby dispatcher and B becomes the primary dispatcher, A stops the model maintenance function and sends the model maintenance file (i.e., the file containing maintenance data) to B. After B receives the model maintenance file sent by the original primary dispatcher, it starts the model maintenance function and performs model maintenance according to the model maintenance file.

[0028] To facilitate the temporary storage and transmission of the model maintenance file, a model maintenance directory and a model transmission directory are pre-configured in the two sets of dispatching automation systems. Among them, the model maintenance file in the configured model maintenance directory is used for model maintenance, and the model maintenance file in the model transmission directory is used for transmission.

[0029] The specific process of the above method is as Figure 1 shown, including:

[0030] 1) Configure a model maintenance directory and a model transmission directory in the two systems respectively;

[0031] 2) When the original primary dispatcher becomes the standby dispatcher and the original standby dispatcher becomes the primary dispatcher:

[0032] 21) The current primary dispatcher checks its own model maintenance directory. If the model data file does not exist, copy the model data file in its own model transmission directory to the model maintenance directory and enable the model maintenance function;

[0033] If the model data file does not exist in its own model transmission directory, issue an alarm for abnormal dual-active synchronization of the model;

[0034] 22) The current standby dispatcher stops the model maintenance function, checks its own model maintenance directory. If the model data file exists, transmit the model data file to the model transmission directory of the current primary dispatcher.

[0035] Based on the above method, the present application discloses a corresponding software device, namely a device for dual-active maintenance of models between the primary and standby systems of dispatching automation, including:

[0036] Main standby module: In response to detecting that itself changes from the main controller to the standby controller and there is model maintenance when itself is the main controller, stop the model maintenance function and send the model maintenance file to the current main controller.

[0037] Standby main module: In response to detecting that itself changes from the standby controller to the main controller and receiving the model maintenance file sent by the original main controller, start the model maintenance function and perform model maintenance according to the model maintenance file.
