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.
