Research on the Digital Measurement System for Marine Electric Network Power Quality

This paper analyzes the characteristics of marine electric network and its parameters representing power quality; then elaborates the importance of measuring voltage distortion of the marine electric network and suggests that conventional analog measurement should be replaced by digital measurement. In addition, a digital measurement system suitable for marine applications is designed to measure voltage harmonics. The experimental results prove the applicability of this system in measuring parameters concerning marine electric network power quality, after the system is used to measure the voltage harmonics distortion of a marine electrical propulsion physical simulation experimental system.
