Problems solved by technology

The status information of secondary system equipment is more and more diverse. The occurrence of faults is not only related to its own operating parameters, but also has a direct or indirect relationship with many factors such as its operating environment and peripheral equipment. How to sort out a large number of operation and maintenance information to establish secondary For the sub-system operation and maintenance business model, it is still difficult to analyze and dig out the causes of equipment failures from a large amount of multi-dimensional related data
[0003] In the current smart substation, the description and modeling of the secondary system data information of the substation is not comprehensive enough; the system specification file (SSD) covers the description information of the primary system of the substation, but SSD is not used in the current operation and maintenance system of the substation. Moreover, there is no suitable mathematical method to describe the correlation model of the primary system interval and the description model of the primary system interval; in order to realize the correlation of the operation mode of the primary and secondary systems, and to treat the operation and maintenance of the secondary system from the perspective of power grid operation risk management and control, it is necessary to configure the primary system of the substation. The association relationship of the secondary system, and establish the corresponding operation and maintenance business model and association relationship model, completely describe the data information of the secondary system of the substation, and realize the standardization of data information

Embodiment Construction

[0030] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings of the description.

[0031] Such as figure 1 As shown, the operation and maintenance business model modeling method based on primary and secondary system correlations disclosed in this application, the modeling steps of this method are as follows:

[0032] (1) Establish a primary system interval correlation model, using a matrix to describe the correlation between intervals and intervals in the primary system;

[0033] The primary system interval association model describes the association relationship between intervals and intervals in the primary system, and the primary system interval association model uses the matrix X(p) k×k Describe the relationship between intervals and intervals in the primary system, where k represents the number of intervals.

[0034] (2) Establish a primary system bay description model according to the IEC...

Abstract

A modeling method of an operation and maintenance business model based on an association relation of primary and secondary systems is disclosed. The method includes the steps of firstly, modeling for a primary system; secondly, modeling for a secondary system; thirdly, classifying secondary operation and maintenance information, establishing a primary and secondary association relation, and associating primary equipment with logical nodes of secondary equipment; and fourthly, establishing an IEC61850 data model including a primary model, a second model and the primary and secondary association relation and being capable of supporting the operation and maintenance business. According to the invention, the method is provided with a data basis for comprehensively managing and controlling operating risks of the secondary system of a transformer substation in real time and ensuring safe and reliable operation of the secondary system, and is capable of executing risk management and control right for the transformer substation; and after accumulation of a certain amount of data, statistics can be conducted for system historical data and the causes of the equipment failure can be excavated so as to realize the whole life cycle management of the equipment, improve the efficiency of intelligent operation and maintenance and reduce the maintenance cost of the equipment at the same time.

Description

technical field [0001] The invention belongs to the field of electric power system automation, and in particular relates to an operation and maintenance business model modeling method based on the correlation relationship between primary and secondary systems of substations. Background technique [0002] The development of smart substations has moved from pilot projects to popularization and application in many places. Under the background of smart substation technology, the structure and operation mode of the secondary system have undergone fundamental changes, and the risk points of the secondary system need to be re-understood and recognized. The status information of secondary system equipment is more and more diverse. The occurrence of faults is not only related to its own operating parameters, but also has a direct or indirect relationship with many factors such as its operating environment and peripheral equipment. For the sub-system operation and maintenance busines...
