Title:
DIRECT CURRENT POWER QUALITY MONITORING DEVICE USED IN DIRECT CURRENT DISTRIBUTION, AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/075102
Kind Code:
A1
Abstract:
Disclosed are a direct current power quality monitoring device and an operation method thereof, the device comprising: a first control unit which receives input/output voltage and current values of an A/D converter connected to a power source and calculates power quality data for the direct current power of the A/D converter on the basis of the received voltage and current values; a second control unit which is functionally connected to the first control unit and processes time synchronization for the power quality data calculation; first memory which is functionally connected to the first control unit and stores the calculated power quality data; and a communication interface circuit which transmits at least a portion of the calculated power quality data to an external higher-level server.
