摘要：为节能减排，借鉴铁路电传动技术基础及大型客船、科考船上的电力推进技术并运用到拖网渔船上。为验证节能效果，通过选取船型相似的电力推进拖网渔船与常规推进的拖网渔船进行实船同航速、同拖力的燃油消耗对比试验。结果表明，电力推进拖网渔船在拖网作业中有一定的节能效果，较常规拖网节能5%左右，而在中高速航行中节能效果比较明显，航速也比较快，同比常规船能提高1节左右，节能30%以上。研究认为，在满足渔船工况复杂的情况下，使用电力推进拖网渔船，可以达到节能减排的目的。

Abstract: There are a large number of fishing vessels, and the fuel is also consumed in a huge amount every year in China. In order to conserve energy and reduce emissions, the electric propulsion technology was tried to apply in trawlers with the reference to basic theory of railway electric drive technology, and the electric propulsion technology in large passenger ship and scientific research ship. In order to validate the effect of technology on energy saving, an electric propulsion trawler and a conventional propulsion trawler were tested to compare the differences of fuel consumption at the same speed and drag force. The results showed that the electric propulsion trawler has the function of energy-saving in trawling operations, which can save energy of 5%, and the energy-saving effect is more obvious in middle and high speed, and speed is faster with an increase of 1 knot increase and energy-saving of more than 30% compared with the conventional ship. In conclusion, the goal of energy conservation and emission reduction can be achieved with the application of electric propulsion trawlers, under the satisfaction of various working conditions for the fishing vessels.
