Abstract

The invention relates to a load switching experimental system based on a power line carrier AD hoc network and an operation method of the load switching experimental system. The load switching experimental system includes a core controller, a core power line carrier, a student machine, a mobile power line carrier, a single-phase AC220 power supply and a plurality of load switching experimental tables; the core controller is connected to the single-phase AC220 power supply through the core power line carrier; the student machine is connected to the single-phase AC220 power supply through the mobile power line carrier; each load switching experimental table is directly connected to the single-phase AC220 power supply; each load switching experimental table includes a three-phase motor and aRLC loader, and the three-phase motor and the RLC loader are correspondingly connected to the single-phase to three-phase transformer after passing through a three-phase inverter, a three-phase circuit breaker and a three-phase power meter in sequence; the single-phase to three-phase transformer is connected to the single-phase AC220 power supply; and the three-phase inverter, the three-phase circuit breaker and the three-phase power meter are further correspondingly connected to the single-phase AC220 power supply through the power line carrier. According to the load switching experimental system based on the power line carrier AD hoc network, the AD hoc network among the experimental tables is realized by a power circuit.

Description

technical field [0001] The invention relates to a teaching experiment device, in particular to a power system experiment device, in particular to a load switching experiment system based on a power carrier ad hoc network and an operation method thereof. Background technique [0002] At present, most of the experimental teaching devices of strong current class are powered by three-phase three-wire AC power supply, and all of them operate independently. Multiple experimental devices cannot communicate with each other through the MODBUS protocol, and the scalability is poor. A small number of experimental platforms that can communicate with each other through the MODBUS protocol are also implemented through wired communication lines or wireless data transmission stations. The wired communication line method requires a lot of additional wiring; the signal of the wireless data transmission station may be interfered, resulting in instability. Contents of the invention [0003]...
