Back-to-back direct current transmission engineering converter station energy consumption monitoring device, system and method

The invention provides a back-to-back direct current transmission engineering converter station energy consumption monitoring device, system and method. A DSP chip and an ARM chip are included. The DSP chip collects an alternating current or direct current original sampling value and sends the value to a data acquisition module, and the data acquisition module transmits the collected data to the ARM chip through a data interaction module. The ARM chip includes a parameter management module, a statistical analysis module, and a record storage module, and the parameter management module, the statistical analysis module, and the record storage module are connected to a communication unit through a communication interface of the ARM chip. The parameter management module, the statistical analysis module, and the record storage module are connected to a display unit through a display interface of the ARM chip, and the record storage module is further connected to a storage unit. A power supply unit is used to suppl
