Power system computer protection comprehensive training device

  Product name

  Power system computer protection comprehensive training device

  Model (Type)



  1. The core equipment of the training device - microcomputer circuit measurement and control device, microcomputer transformer measurement and control device, and has a physical simulation primary system, so that students can intuitively understand the changes in power parameters when various short-circuit faults occur in the power system. The training device has an upgrade interface, and users can expand the relay protection and secondary circuit training projects based on the simulated primary system.

  2. Communication networking: The training device has an RS-485 bus interface, which can realize the SCADA of the power system based on the microcomputer measurement and control device.

  3. Laboratory remote management system software (in order to avoid intellectual property disputes, the bidding site needs to provide computer software copyright certificates and demonstration videos)

  The system integrates the power management system of the remote laboratory bench, monitors and queries the power switch status of the student laboratory bench through a mobile phone or other mobile terminal system; turns on and off the power of the student laboratory bench individually; turns on or all off the power supply function of the laboratory bench; regularly turns on and off the power supply function .
