补给船电站功率因数改善方案

Power-factor Improvement Solution for Replenishment Ship Power Station

海上航行横向补给是目前较为先进且广泛应用于大型综合补给船的一种补给方式,由于横向补给装置使用工况的特殊性,其接入船舶电网会引起电站功率因数下降,影响船舶电力系统正常运行。文章分析了横补装置引起电站功率因数下降的原因,阐述了改善船舶电网功率因数的必要性,并从船舶总体设计角度出发,在不改变原有设备技术状态的前提下,提出使用有源动态无功补偿装置(SVG)对补给装置进行就地补偿的方案,理论计算并校核了补偿装置容量,验证其满足船舶电网的设计要求。

The underway alongside replenishment ＆ an advanced supply method and widely used in naval replenishment ship. Due to the special working condition of the replenishment equipment, the power-factor is decreased when the replenishment equipment is powered on, which brings many disadvantages to the ship power station. The cause of power-factor decreasing and the necessity of improving the power-factor are analyzed in this article. Making reactive compensation to the replenishment equipment locally with Static Var Generator （SVG） is introduced from the overall design perspective without changing the existing technical state. The capacity of the reactive compensation is calculated and also verified to meet the power station requirements.
