Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in detail as follows:

[0022] 1. Define the functions to be realized by the target substation automation system;

[0023] 2. Decompose the functions required by the whole station into IEC61850 standard logical nodes from the perspective of the system, such as: a typical 220kV substation (construction scale: 2 sets of 180MVA main transformers, 2 circuits of 220kV outgoing lines, 8 circuits of 110kV outgoing lines, 24 circuits of 10kV outgoing lines; 220kV part of double busbar wiring, 110kV part of double busbar wiring, 10kV part of single busbar double section wiring) is broken down as follows:

[0024] 1) Protection function:

[0025] 220kV line: line current differential protection (PDIF), distance protection (PDIS), overcurrent protection (PTOC), zero sequence overcurrent protection (PIOC), remote tripping (PSCH)

[0026] 220kV busbar: busbar differential protection (PDIF), overcurr...

Abstract

The invention discloses a method for realizing an automatic system of an intelligent transformer station. The method is characterized by comprising the following steps of: (1) determining a function to be realized by the automatic system of a target transformer station; (2) decomposing the function into IEC61850 standard logic nodes according to the requirements of equipment in the station on protection, measurement and control; (3) classifying the logic nodes according to a station level, a spacing level and a procedure level specified in a standard; (4) giving an intelligent transformer station system framework represented by the formation of the logic nodes; (5) configuring the logic nodes according to an optimal rule; (6) determining the function and the network structure of an IED (Intelligent Electronic Device); (7) verifying a system configuration file and comparing the file with an expected requirement; and (8) downloading a corresponding IED configuration file. Due to the adoption of the method, blanks on the aspects of implementation methods and flows in an intelligent transformer station design standard are filled, and a plurality of problems existing in the design of the automatic system for the conventional intelligent transformer station are solved.

Description

technical field [0001] The invention belongs to the field of electric power engineering, and in particular relates to a method for realizing an automatic system of a substation in a power system. Background technique [0002] Smart substation is an important part of smart grid. "Technical Guidelines for Smart Substations" (Q / GDW383-2009) describes the development goals of smart substations as follows: high-reliability equipment is the strong foundation of substations, comprehensive analysis and automatic collaborative control are the key to substation intelligence, equipment information digitization, Functional integration, compact structure, and state-of-the-art maintenance are the development directions, and efficient operation and maintenance is the ultimate goal. [0003] "Smart Substation Technical Guidelines" (Q / GDW 383-2009) divides the smart substation system architecture into three layers according to the substation functions: station control layer, interval layer ...
