摘要：为解决海上平台起重机高能耗、高排放的问题，提高能源利用效率，综合考虑动力电池成本较高和柴油机在安全可靠方面不可替代的典型优势，提出一种海上平台起重机用混合动力方案，通过监测电池荷电状态（state of charge，SOC）与起重机动力负载，设计协同控制策略，并进行起重机典型作业工况下的仿真验证。结果表明：柴油机-锂电池混合动力系统驱动的起重机燃油消耗和CO₂排放均明显下降；经过8 h典型作业循环，传统柴油机与混合动力驱动的起重机燃油消耗分别为141.0、120.2 kg，CO₂排放分别为435.7、371.3 kg，燃油消耗和CO₂排放均降低14.8%。

Abstract: In order to solve the problems of high energy consumption and high emissions of offshore platform cranes and improve energy efficiency, considering the cost of power batteries and the irreplaceable typical advantages of diesel engines in safety and reliability, a hybrid power scheme for offshore platform cranes is proposed, which monitored the state of charge(SOC) of batteries and the dynamic load of the crane, the collaborative control strategy is designed, and the simulation verification under the typical working conditions of the crane is carried out. The results show that the fuel consumption and CO₂ emission of the heavy duty diesel engine driven by the diesel engine-lithium battery hybrid system are significantly reduced. After 8 h typical operation cycle, the fuel consumption of the traditional diesel engine crane and the hybrid crane are 141.0 kg and 120.2 kg, with the CO₂ emissions are 435.7 kg and 371.3 kg, respectively, both the fuel consumption and CO₂ emissions are reduced by 14. 8%.
