Method of Noise Reduction for High-Voltage Systems Applied in Subsea Plants

This paper is conducted a research of the cable and filter design considering the deep sea floor environment. The electric architecture which is being used in the subsea plant is comprised of the power supply unit of the high voltage, high-capacity drive system, long cable, and electric motor in the sea area. Conducted emission is occurred by the rapid voltage change at the moment of switching at high speed of inverter for driving motors. The more the length of the cable is lengthened, the worse the motor is influenced by transient voltage. Thus, the over voltage occurred in the drive motor was confirmed by designed wire which is considered R, L, line-to-line C, line-to-gnd C of long cable used in the subsea plant. A guide line of the subsea plant model is also suggested by using a filter to reduce conducted noise of PWM inverter drive-system.
