摘　　要：多用途重吊船具有装载灵活和装卸能力强等特点,船用起重机是其核心设备。探讨船用起重机对重吊船电站设计的影响,主要包括电站容量配置、电站管理系统设计、电缆及保护电器选型和逆功率处理等。通过需要系数法和概率计算法确定起重机的功率,确保发电机容量满足实际需求。为功率管理系统设计重载问询和功率限制功能,保证系统安全运行。针对逆功率问题,提出逆功吸收电阻、功率限制和电池吸收等处理方案,为电站设计提供系统性指导。The electric power system for a multi-purpose heavy lift vessel needs special design effort because it has to ensure the operation of the cranes onboard,which cause great surge loading.This paper explores the impact of cranes on the design of power plants on multi-purpose heavy lift vessels,focusing on the power station capacity configuration,the power management,reverse power handling,and the selection of cable and protection devices.The power requirements of the cranes are determined based on demand coefficients and probability calculation to ensure that the generator capacity meets actual needs.The design includes heavy load request and power limitation functions in the power management system to ensure safe operation.Various solutions for reverse power handling are investigated,including reverse power absorption resistors,power limitation,and battery absorption.
