Abstract

Nowadays, energy efficiency and its various aspects are quite important than before in marine application. Also in modern cruise ships, energy consumption of hotel load is as crucial as propulsion load and should be permanently provided without even short term interruption. This study has concentrated on hotel lighting load and its harmonic contents influence on marine cast-resin transformer in ship electric system. Advantages and disadvantages of conventional and recent developed lighting systems are debated. Harmonic contents of incandescent, fluorescent, Compact Fluorescent (CF) and Light Emitted Diode (LED) lamps are measured and discussed. THD level of each and every lamp is also calculated. The influence of non-linear load on hot-spot temperature rise of cast-resin transformer is discussed. Finally, distribution cast-resin transformer de-rating and its aging rate under non-sinusoidal condition initiated by lighting load is simulated and influence of each load on transformer is discussed.

酒店照明负荷对船用铸造树脂配电变压器老化率的影响

如今，能源效率及其各个方面在船舶应用中比以往更加重要。同样，在现代游轮中，酒店负荷的能耗与推进负荷一样重要，应该永久提供，即使是短期中断。本文主要研究了酒店照明负荷及其谐波含量对船舶电气系统中船用铸造树脂变压器的影响。讨论了传统和最近开发的照明系统的优点和缺点。对白炽灯、荧光灯、紧凑型荧光灯和LED灯的谐波含量进行了测量和讨论。并计算每盏灯的THD电平。讨论了非线性载荷对铸树脂变压器热点温升的影响。最后，模拟了非正弦状态下由照明负荷引起的分布型铸造树脂变压器的劣化和老化速率，并讨论了各种负荷对变压器的影响。
