Embodiment Construction

[0018] For better setting forth the advantages of the present invention, its embodiment is as follows:

[0019] Such as figure 1 The shown method for optimizing the virtual circuit design process of the smart substation includes the following steps:

[0020] (1) Standardized design of virtual terminals; manufacturers provide equipment model files to add standardized descriptions of signals. According to the main wiring mode and secondary equipment configuration mode in smart substations of different voltage levels, the manufacturer has already carried out standardized design specifications for corresponding virtual terminals. The definitions and descriptions of SV and GOOSE channels are all standardized to ensure that the descriptions of the same signals are completely consistent among the communication signals of all devices in the station.

[0021] (2) Smart substation summary virtual terminal table; smart substation equipment derives a virtual terminal table with signal s...

Abstract

The invention discloses an optimization method for virtual circuit design of smart substations. The optimization method comprises the steps of 1) performing virtual terminal standardization design: according to different primary wiring methods and secondary equipment configuration methods in smart substations at different voltage degrees, setting unified and specified relevant virtual terminal standardization design; 2) establishing a smart substation summarization virtual terminal table: combining the virtual terminal tables of various smart substation equipment to form a summarization table and adding interval description attributes; 3) correlating the virtual terminals with identical signal descriptions and interval descriptions and connecting the virtual terminals with consistent signals by using an auxiliary design tool. The optimization method for virtual circuit design of smart substations has the advantages that the virtual circuit design process of the smart substations can be optimized, the workload at a design stage is reduced, and the burdens and the potential hazards caused by substation information digitalization and networking to the current smart substation design work are avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent substations, in particular to an optimization method for virtual circuit design of intelligent substations. Background technique [0002] In conventional substations, information is exchanged between secondary equipment and primary equipment, and between secondary equipment and secondary equipment through a large number of cables. Smart substations realize the on-site digitalization of measurement and control of primary equipment through intelligent components, thereby A small number of optical cables replace a large number of cables, but the reduction in the number of optical cables and cables does not mean that the workload is reduced. The simplification of the hardware circuit and the dependence of the device on the digitization and networking of information, the configuration workload of various virtual circuits Dramatic increase. [0003] The number of virtual loop designs in smart subst...
