The receiving module is used for receiving the alarm information and storing the alarm information in the storage module. The mapping module is used for determining whether the alarm object library has the alarm information corresponding to the mapping method. The reasoning module is used for generating event information according to the reasoning knowledge base.
Specifically, the storage module stores an alarm object library and an inference knowledge library, and when the receiving module receives various alarm information, the receiving module stores the alarm information in the storage module. The mapping module determines whether the corresponding mapping method corresponds to the specific alarm information in the alarm object library, and if the corresponding mapping method corresponds to the specific alarm information in the alarm object library, the inference module generates corresponding event information according to the inference knowledge base.
By the scheme of the embodiment, the efficiency of generating the information event can be greatly improved, and the power grid fault monitoring full-service system has stronger adaptability by updating the inference rule in the inference knowledge base so as to adapt to new alarm information generated by upgrading the power grid system.
As shown in fig. 1, in this embodiment, the grid fault monitoring all-service system in the regulation and control integration mode includes a storage module, a receiving module, a mapping module, and an inference module. The storage module stores alarm information, an alarm object library and an inference knowledge library. The alarm information refers to abnormal information of the power grid system, such as voltage abnormality of a certain line in a certain area. The alarm object library comprises various mapping methods of alarm information, and the inference knowledge library comprises inference rules. The receiving module is used for receiving the alarm information and storing the alarm information in the storage module. The mapping module is used for determining whether the alarm object library has specific alarm information corresponding to the mapping method. And the reasoning module is used for generating the event information according to the reasoning knowledge base.
It should be noted that the alarm object library and the inference knowledge library can be updated in time to deal with new alarm information corresponding to new power grid technologies and equipment.
As shown in fig. 4, the specific process is that the receiving module receives the alarm information from the power grid system or other prior art approaches, and the mapping module receives the alarm information and determines whether the alarm object library has a mapping method corresponding to the alarm information.

In addition, the power grid fault monitoring all-service system provided by the embodiment can also enable the power grid fault monitoring all-service system to have adaptability by updating the alarm object library and the inference knowledge library so as to adapt to new alarm information generated by upgrading the power grid system, and has good practicability.

As shown in fig. 2 and 3, the steps of converting the alarm information into the standard typical information by the alarm information module are as follows:
s201: dividing the alarm information into a plurality of typical intervals according to the voltage level;
s202: dividing each typical interval into a plurality of typical devices according to the device names;
s203: finally, each representative device is subdivided into a number of base information objects by base object name.
The typical interval types are divided into a plurality of typical intervals such as a typical interval A, a typical interval B, a typical interval C and the like; each typical interval is divided into a plurality of typical devices, for example, the typical interval A is divided into a typical device AA, a typical device AB, a typical device AC and the like; each representative device is further divided into a plurality of basic information objects, for example, the representative device AA is divided into a basic information object AAA, a basic information object AAB, a basic information object AAC, and so on.
For example, typical interval types are 110kV lines, 220kV lines, 35kV and below, and so on. Wherein, the typical interval of 35kV and below can be divided into typical equipment such as a circuit breaker, a protection and measurement integrated device, an operation box and the like. The circuit breaker can be classified as a specific switch.
Through the embodiment, the alarm information can be converted into the standard typical information quickly and efficiently, so that the mapping module can quickly correspond various alarm information to a specific mapping rule.
In addition, in the embodiment, the inference knowledge base contains inference rules for the inference module to generate the event information. And when the alarm object library is determined to have the alarm information corresponding to the mapping method, the inference module infers and obtains the event information according to the specific inference rule corresponding to the mapping method. The inference rule can be updated to adapt to new alarm information generated by upgrading of the power grid system.
In addition, in this embodiment, the inference knowledge base further includes a supplementary rule, and if it is determined that the inference knowledge base does not have the inference rule corresponding to the alarm information, it is determined whether the inference knowledge base has the supplementary rule corresponding to the alarm information. And if the inference knowledge base has the alarm information corresponding to the supplementary rule, generating the event information by inference according to the supplementary rule.
In addition, in this embodiment, the grid fault monitoring all-service system in the regulation and control integration mode further includes a display module, and the display module is configured to display the generated event information. Specifically, the display module comprises a display screen, the display module of the application can realize different delay window-entering strategies and display methods for the event according to the grade of the event, and the specific display rules of the display screen are as follows:
first, the top left corner window is a to-do event window for showing events that need to be handled immediately, wherein accident events are only displayed in this window.
Second, the lower left corner is a prompt events window for showing the returned events that need to be processed.
Third, the top right corner is a window event window for presenting generated events, but does not need immediate processing, where notification-like events are only displayed in this window.
Fourth, the lower right corner is an alarm information window that shows the original unprocessed alarm signal.
