Problems solved by technology

However, a typical feature of IEC61850-based communication services in smart substations is a self-describing object-oriented mode, while the current communication between substations and IEC61970-based dispatching master stations mostly uses the IEC60870-5 series of communication protocols for information points. There is a considerable difference in the construction of the communication model between the two, and at the same time, the digital substation model cannot be directly connected with the dispatching master station IEC61970CIM. It is an urgent problem to be solved at present to provide scalable, seamlessly coordinated model and data integration communication for the dispatching master station

Embodiment Construction

[0025] In order to describe the present invention more specifically, the dynamic modeling method of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0026] Such as figure 1 As shown, a dynamic modeling method of a conventional substation based on the IEC standard includes the following steps:

[0027] (1) Establish an object-oriented model.

[0028] Model the equipment and power system operation information in the conventional substation based on the IEC 61850 standard to obtain the object-oriented model of the conventional substation;

[0029] The primary and secondary equipment of the substation have their own division of labor. The former is responsible for completing its power transmission and distribution tasks, and the latter equipment is responsible for monitoring the operation of the primary equipment. Therefore, taking primary equipment as the object and combining the IEC 61850 standard to model equ...

Abstract

The invention discloses a dynamic modeling method of a conventional substation based on the IEC standard, which includes the steps as follows: firstly, building an object-oriented model; secondly, obtaining an entity model through mapping and supplementation; thirdly, building a UCIM model of a master station system as per the entity model; and fourthly, updating the UCIM model. The method effectively solves the problems of communication collision and efficiency between communication of an information point oriented dispatching master station and communication of an object-oriented substation, improves the efficiency of technology upgrade and innovation of a great amount of conventional substations, and reduces working pressure of substations and management maintenance staff for dispatching automatization.

Description

technical field [0001] The invention belongs to the technical field of power system modeling, and in particular relates to a dynamic modeling method of a conventional substation based on IEC standards. Background technique [0002] With the rise of the power market and the expansion of the power system, the amount of information is increasing, requiring fast and accurate integration, consolidation and dissemination of real-time information within various automation systems; [0003] As a new thing, the IEC 61850 standard is significantly different from the past substation automation technology, so it is impossible to fully realize the application of the IEC 61850 standard within a certain period of time, and there is no need to complete such a replacement process overnight. Therefore, non-IEC 61850 systems (and IEDs) and IEC61850-based systems (and IEDs) will coexist within a certain period of time. [0004] The IEC 61850 standard is a popular research topic at home and abr...
