Problems solved by technology

One is the bench-type simulation experiment device currently configured in the power electronics laboratories of various universities. The main and key electronic and electrical components are packaged behind the bench. What users see and operate are the plug-in holes, operation buttons, Knobs, indicator lights, etc., which prevent researchers and users from having a deep understanding of the structure and control of internal variables, and are only suitable for confirmatory undergraduate experiments; one is a single small-capacity experimental device, launched by Taiwan GW Inst The PTS-1000 power electronics training system is represented by the PTS-1000 power electronics training system. This kind of system has small capacity and single function; the other is the micro-grid and new energy power generation experimental system configured by many scientific research institutes. The hardware is not open, and the start-up operation and process adjustment are very complicated, which is not conducive to learning and mastering

Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] The upper monitoring layer communicates with the device layer through the communication network and exchanges data. The communication network is implemented in the form of Ethernet, serial communication, CAN bus, etc. This device uses CAN bus. CAN is the abbreviation of Controller Area Network (CAN). It is an ISO international standardized serial communication protocol. The device realizes internal multi-machine communication through the CAN bus, and obtains all variables such as telemetry, remote signaling, remote adjustment and remote control. There is a CAN interface on the control board of each converter unit at the equipment layer, and each unit communicates with each other through the serial port. The CAN node device sends a mode start command, each CAN node will receive the serial port data frame, and the bottom adjustment frame deframing part j...

The upper monitoring layer includes a monitoring unit and a measuring instrument, and the device layer includes a chopper converter unit and an AC and DC converter unit. The technical scheme provided by the invention allowspeople who are in contact with the electric power technology in the early stage to quickly understand the equipment composition and working principle of a power electronic converter, people engaged inrelated technological development can carry out secondary development and research based on a display platform provided by the invention and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power electronics, and specifically relates to a display platform for a transparent and open two-stage bidirectional multifunctional converter. Background technique [0002] Power electronic power converters are the basis of power systems such as AC-DC hybrid distribution networks, micro-grids, and new energy power generation. It is of great significance for practitioners who do not have a background in power electronics technology to quickly grasp related basic technologies and working principles. Experimental equipment that can meet this requirement can be divided into three categories. One is the bench-type simulation experiment device currently configured in the power electronics laboratories of various universities. The main and key electronic and electrical components are packaged behind the bench. What users see and operate are the plug-in holes, operation buttons, Knobs, indicator lights, etc., w...
