Problems solved by technology
[0005] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned manual drawing of existing engineering personnel, and provide a method for automatically generating the wiring diagram of the primary system based on the description model of the substation system specification, so as to solve the problem that the primary system cannot be obtained in the current intelligent substation automation system. The wiring diagram must rely on manual drawing; after automatic drawing, it can also realize the automatic association configuration of graphics and models, reduce the possibility of errors due to manual configuration, and improve the configuration efficiency of substation automation system

Embodiment Construction
[0036] The present invention is an automatic drawing method for primary system wiring based on substation specification description, and its steps are as follows:
[0037] 1. A system topology analysis
[0038] By analyzing the key primary equipment inside the SSD middle bay and its topological structure in the primary wiring, the bay type is identified. According to the functional logic, it is divided into: busbar interval, line interval, transformer interval on each side, main transformer body interval, capacitive reactance interval, bus coupler and section interval, circuit breaker interval, etc.
[0039] Different wiring methods correspond to different layout settings. All wiring methods are composed of the following four types of wiring, namely, single-female wiring, segmented wiring, double-female wiring, and three-half wiring. The identification methods are as follows:
[0040] a. Traverse the number of buses busCount under the current voltage level;
[0041] b. If bu...

The invention discloses a primary system wiring diagram automatic generation method based on substation specification description. According to existing engineering schemes, a system specification description file is analyzed, a corresponding model is generated in a database, a primary wire diagram is drawn manually by an engineer, and diagram-model association configuration is performed. According to the method, types and wiring modes of all intervals of a substation are automatically recognized based on a substation system specification description file, and a primary system wiring diagram is automatically generated according to a primary system topological structure and relevant element types obtained through recognition in combination with a multi-scale iterative placement algorithm containing a voltage grade scale, an interval scale, a primary equipment scale and a connecting wire scale. Through the method, the problem that a primary system wiring diagram cannot be acquired in a current intelligent substation automatic system and must depend on manual drawing is solved; automatic association configuration of the diagram and the model is also realized after automatic diagram generation, the possibility that an error occurs due to manual configuration is lowered, and the configuration efficiency of the substation automatic system is improved.
Description
technical field [0001] The invention relates to the field of intelligent substation automation systems in power systems, in particular to an automatic drawing method for primary system wiring based on substation specification descriptions. Background technique [0002] The IEC 61850 standard is the only standard adopted by smart substations. IEC 61850 is a standard based on object-oriented modeling, applying object-oriented modeling technology, and formulating Substation Configuration Language (SCL). Unified configuration modeling of equipment and equipment can easily describe the basic functions and accessible information models of equipment in the substation, as well as the organizational structure and function distribution of the entire system. [0003] SSD (System Specification Description), as the only system specification description file in the whole station, is mainly used to describe the smart substation model. Its model feature is the object hierarchy based on the ...
