Description

Panoramic information platform based on grid regulation and control integration

technical field

The invention relates to a processing platform for various monitoring information and business information under the integration of power grid regulation and control, in particular to a panoramic information platform based on the integration of power grid regulation and control.

Background technique

"Integration of regulation and control" has broken the traditional scope of dispatching business, and the power grid dispatching center has expanded into a centralized monitoring and command and control center for power grids and equipment. Under the intensive management mode, the safety pressure and workload of the control center continue to increase, and the real-time and quasi-real-time information of various production operations is gradually collected to the dispatching platform. The collection point of information and management processes also undertakes the responsibility of monitoring real-time power grid production and operation status.

When a power dispatching alarm event occurs, the dispatching and monitoring personnel will determine the severity of the event, and obtain relevant business data (such as power grid operation status) and various System-related event records (such as SOE events, fault recording files, etc.), and then analyze the power dispatching alarm information, and notify various professionals for collaborative processing when necessary. This kind of power dispatching alarm information method based on manual judgment and manual request is the most common technical solution at present.

However, in addition to the EMS system, the power transmission and transformation monitoring systems in operation mainly include transmission online monitoring systems and power transformation online monitoring systems; network communications mainly include main network communication monitoring systems and distribution network communication monitoring systems; other systems include substation video ( Fire safety) auxiliary system, transmission line video auxiliary system, fault information system, weather information system, etc. These systems have independent interfaces, a large amount of information, and strong professionalism. It is difficult to efficiently obtain the required information only by manually switching interfaces and scanning and monitoring systems one by one.

In addition, the existing production and business systems, such as the online monitoring system for power transmission and transformation, comprehensive disaster reduction and prevention systems, etc., although they integrate data from multiple systems, they still basically integrate data by specialty and lack comprehensive analysis capabilities (such as Interval comprehensive analysis of multi-professional system data to form a brief result report function), making it difficult for non-equipment professionals (such as dispatchers) to use.

Contents of the invention

The purpose of the present invention is to provide a panorama information platform based on the integration of power grid regulation and control, which reduces the workload, improves the work efficiency and ensures the safe operation of the power system according to the shortcomings of the prior art.

The purpose of the present invention is achieved by the following approach:

② Import the full data model of the following source systems through the panoramic data platform: during the import process, the mapping relationship between the source system objects and the imported objects is established. The specific steps are:

First, the EMS system is the source system first imported into the platform. During the import process of the full data model, data description conversion is performed: first, according to the determined mapping logic, import object description data by class, create corresponding objects inside the platform, and Record the mapping relationship between the EMS system object and the newly generated platform object; while creating the object, the attribute value of the related object will be imported together; after all the platform objects are created, start the mapping import of the association relationship, this The process needs to use the EMS system object-platform object mapping determined in the previous stage: convert the relationship between the two objects described in the EMS system into the relationship between the two objects in the platform;

Then it is the import of substation equipment monitoring system. During the import process, first determine the mapping of common description objects, and then convert and import the data description;

Subsequent imported systems are the data of transmission line monitoring system, substation equipment auxiliary system video, main network communication system, distribution network communication system and transmission line video system, as well as new system data and old system data of protection information; each subsequent imported system For system data, the first thing that needs to be determined is to merge with other system data imported first. The merge strategy is to confirm the large container first, and then narrow down the scope of the mapping step by step; the judgment of whether the data description points to the same object is based on the The uniqueness of the type and name information of the converted object within the specified range;

③The import of incremental data adopts the method of firstly comparing the whole model, generating a difference, and then updating the difference to the platform; the comparison method is as follows:

First obtain the current object description of the source system, compare it with the last exported data, and generate a model difference: determine the addition, update, and deletion of objects; then generate and maintain the source system object-platform object mapping table according to the previous import process, which will be The model difference results of the first step are applied to the platform: create new object descriptions, update and delete original objects, modify and maintain source system objects-platform object mapping table;
