Abstract
Due to the seriousness of oceanic environmental pollution and the strict restrictions imposed by marine pollution protocol, the photovoltaic (PV) system has been tried to be implemented in traditional ships that use fossil fuel for power generation. This paper investigates the impacts of a large PV system on the ship power system. The installation of PV system of various operation modes on ship power system will significantly affect the power quality of ship grid. In this paper, one practical ship-PV power system of the COSCO TENGFEI vehicle carrier is selected for study. Various power quality issues like the voltage unbalance factor, voltage deviation, frequency deviation, harmonic ratio as well as total harmonic distortion (THD) are investigated and calculated by the calculation methods suggested by the International Electrotechnical Commission (IEC) and ship classification societies. The results will be compared with the relative standards to demonstrate the feasibility of the PV system to be installed in the ship power system.
