Low-voltage transformer district simulated practice training system based on rural power grid intelligent low-voltage distribution box

Abstract

The invention discloses a low-voltage transformer district simulated practice training system based on a rural power grid intelligent low-voltage distribution box. The system comprises an intelligent low-voltage management master station system in a practice training room, and a simulated intelligent distribution transformer district and an intelligent ammeter of a low-voltage electric power user which are in the practice training room, wherein the intelligent low-voltage management master station system comprises a data storage server, a data processing server, a preposition server, a Web server, a gateway server, a database server and a management terminal. According to the low-voltage transformer district simulated practice training system based on the rural power grid intelligent low-voltage distribution box, the rural power grid intelligent low-voltage distribution box is served as a basic unit, real-time monitoring system simulation of electric power parameter simulating, controlling and managing is carried out on distribution transform and the low-voltage electric power user which are matched with the rural power grid intelligent low-voltage distribution box. Through the intelligent low-voltage management master station system in the practice training room, the distribution transform parameter monitoring, measuring, the electricity information collecting, the communicating, the dynamic reactive power compensation controlling, the harmonic restraining and the three-phase imbalance governing on the simulated intelligent distribution transformer district can be achieved, and the integrated application function of the electricity safety and the electric power facility protection real-time monitoring and early warning can be achieved.

Description

technical field [0001] The invention belongs to the technical field of rural power grids, in particular to a low-voltage station simulation training system based on an intelligent low-voltage distribution box of the rural power grid. Background technique [0002] China's rural power grid has already established a certain foundation after large-scale rural power grid transformation, but there are still generally insufficient infrastructure investment, unreasonable grid structure, and relatively backward technological means. It is economical, practical and effective, and will be constructed in stages. [0003] At present, the teaching and training of the rural grid intelligent power distribution system based on the intelligent low-voltage distribution box of the rural grid and the relevant skills of user load and measurement at home and abroad are only on-site education and operation demonstration in the way of masters and apprentices. Due to the singleness of the on-site sit...

Problems solved by technology

[0002] China's rural power grid has already established a certain foundation after large-scale rural power grid transformation, but there are still generally insufficient infrastructure investment, unreasonable grid structure, and relatively backward technological means. The characteristics of economic benefits, practical results, construction in stages

[0003] At present, the teaching and training of the rural grid intelligent power distribution system based on the intelligent low-voltage distribution box of the rural grid and the relevant skills of user load and measurement at home and abroad are only on-site education and operation demonstration in the way of masters and apprentices. Due to the singleness of the on-site situation, the master cannot demonstrate the failure of the intelligent low-voltage distribution box of the rural power grid, the problems and solutions of the single-phase and three-phase metering users and the main station software system, and can only adopt the teaching method of solving problems when they arise, so that there are It is impossible to reproduce the possible fault phenomena that may occur in the operation of the intelligent low-voltage distribution box of the rural power grid. At the same time, the test operation data of the intelligent distribution transformer terminal software of the rural power grid is single, and it is impossible to carry out personalized assessments for multiple students. This kind of teaching The method is not conducive to students' understanding and learning, and has been criticized a lot in teaching practice

With the development of smart grid, especially after the large-scale promotion of intelligent upgrading and transformation of rural power grid, there are people who are not familiar with new equipment and new products. problem
