A method for realizing partition definition and pre-check of provincial and regional model splicing boundary equipment

Abstract

The invention relates to a method for realizing partition definition and pre-verification of provincial and regional model splicing boundary equipment. The method comprises the following steps: 1) establishing a transmission service module of a scheduling modeling system data file and establishing a client module of the scheduling modeling system data file; 2) defining and transmitting upper and lower level boundary definition file formats; 3) formulating a boundary equipment pre-check rule; 4) the local dispatching side sends a request to the provincial dispatching, a boundary definition fileis obtained, and the file comprises existing boundary definition and newly-added boundary information; 5) finishing modification on the newly-added boundary part by the local dispatching side; 6) after the local dispatch exports the model, verifying the boundary equipment according to the pre-verification rule in the step 3), and if the boundary equipment is correct, uploading the model and the modified boundary equipment definition file to the provincial dispatch; And 7) the provincial dispatching client receives the model uploaded by the provincial dispatching and the maintained boundary definition file, updates the provincial dispatching database boundary equipment mapping table, and splices the provincial dispatching model after updating is completed. The provincial dispatching maintenance work is reduced, the model accuracy is ensured, and the model splicing exchange efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power system modeling, and in particular relates to a method for realizing the definition and pre-verification of border equipment partitions for land-saving model splicing based on the JMS protocol when splicing power grid models. Background technique [0002] The characteristics of the wide-area distribution of the interconnected grid have determined the distributed system of power dispatching management. In order to ensure the safe and stable operation of the interconnected grid, each dispatching center must have a comprehensive and accurate understanding of the system. Then, there must be some form of mutual communication and coordination between dispatching centers in order to timely and accurately grasp the real-time operating status of the entire power system. The power grids of each layer and district respectively establish their own models, and merge them into the whole network model through real...

Problems solved by technology

The power grids of each layer and district respectively establish their own models, and merge them into the whole network model through real-time model splicing. The traditional model splicing boundary definition method requires the provincial survey to provide the boundary equipment on the ground survey side and the name of the plant station to which the boundary equipment belongs. Then the provincial dispatching automation personnel fill in the local database. Due to the rapid change of the power grid model, the boundary equipment often changes. The automation personnel not only need to maintain the provincial dispatching boundary change information, but also maintain the definition of the bordering equipment on the ground dispatching side. Information, accuracy and real-time performance cannot be guaranteed, and the efficiency is relatively low
