Wide area synchronized HVDC measurement using IEC 61850 communication

摘要

HVDC-Technology is assuming ever greater importance in the transmission of electric power. This requires development of equipment that takes highly precise and time synchronized measurements in DC systems. The data acquisition, the data transfer and a standardized communication interface are important factors to fulfill the requirements for secure and safe power system operation. This paper describes the development of one such system for HVDC measurement with communications interfaces compliant with IEC 61850. Taking the system modeling as the starting point, the finished measurement system and some initial results of the equipment's operation are presented.
