Embodiment 1

[0048] Such as figure 1 As shown, a BPA model parameter maintenance system based on Web services includes: a database server, a Web server and a client for reading and maintaining model data;

[0049] Considering that the BPA model data is file-type data, the number of parameters of different model cards (that is, the data card corresponding to the equipment model in the BPA model data) is not the same, so the database uses a non-relational model with high reliability and throughput performance. Database MongoDB, all model card parameters are stored in the form of key-value pairs.

[0050] The data stored in the database server include: basic grid model data in BPA format, data in BPA model format, grid operation mode data, personnel and maintenance authority information.

[0051](1) Grid basic model data in BPA format. The basic model data is the model data with the most complete grid structure, the most complete power equipment, and the latest model parameters, including: ...

Embodiment 2

[0072] Such as figure 2 As shown, a method for maintaining BPA model parameters based on Web services includes steps:

[0073] Step 1. Write the power grid operation mode model data selected by the administrator to be delivered, the set maintenance authority, delivery date and maintenance deadline to the database by calling the web service interface, and set the data delivery flag in the database , if it is set to "11", reset the data submission status flag, if it is set to "00", the model data delivery is completed;

[0074] Maintenance permissions include: maintain user information, allow maintenance of data information, allow maintenance partition information, and permission types;

[0075] Maintenance permission settings include:

[0076] Set user information on the client that allows model data maintenance. User information includes user name, user role, department, contact information, etc. User roles include administrator and maintenance personnel. Administrators hav...

Abstract

The invention discloses a BPA model parameter maintenance method and system based on Web service, and the method comprises the steps of writing selected to-be-issued power grid operation mode model data and set maintenance authority into a database through calling a Web service interface, enabling a data issuing flag bit and a data submitting state flag bit to be reset in the database, and completing the issuing of model data; reading and analyzing to-be-maintained power grid operation mode model data from the database, and performing maintenance operation on the equipment model parameters according to the maintenance authority; and calling a Web service interface after data maintenance is completed, writing maintenance personnel, completion time and modification record information into adatabase, and marking a position bit of a submission state to complete submission of maintenance data. Through model data issuing, modification and submission, distributed maintenance of power grid basic model data and operation mode data is realized.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method and system for maintaining BPA model parameters based on Web services. Background technique [0002] PSD-BPA (BPA for short) is a set of electromechanical transient simulation software introduced and developed by China Electric Power Research Institute, and has been widely used in the field of power grid planning, design and operation analysis in my country. At present, most power companies have relatively complete BPA simulation software. model data. BPA model data adopts text file format to store power grid model data in the form of strings. Different types of power equipment models such as generators, transformers, and lines correspond to one or more rows of data cards, and the data in different position intervals in the cards correspond to different parameters of the equipment. [0003] For a provincial power grid, its jurisdiction can be divided into provincia...
