摘　　要：在国家提出节能减排要求的背景下,混合动力系统在工程机械上的应用研究正成为工程机械节能和环保研究的一个热点。采用以超级电容作为储能元件的工程机械环保节能新型混合动力系统,以D2LQ-25型轮胎起重机为例,利用Saber仿真软件作为工具,建立轮胎起重机新型混合动力系统仿真模型,主要包括柴油发电机组模块、超级电容器模块、DC-DC变换器模块以及异步电机变频调速模块等,通过对混合动力系统中柴油机输出功率谱图与未进行混合动力改造机型实测结果对比,分析起重机一次作业循环过程中的节能潜力,并且进行了混合动力系统中柴油机与超级电容器的功率分配分析、超级电容器的充放电过程的仿真分析,得出新型混合动力系统的节能结果,在理论上论证这种新型混合动力系统的实用价值。In the background of national requirements of energy-saving and emission control,application of hybrid power system in construc- tion machinery has become a hot point in the research of ener- gy-saving and environment protection for construction machinery. Super capacitor is utilized as energy-reserving part in new type hybrid power system of environment protection and energy-saving for construction machinery.Taking model D2LQ-25 wheel crane as an example,simulation model of the hybrid power system on wheel crane is estabhshed with the tool of Saber simulation soft- ware,including diesel generator module,super capacitor module, DC-AC transfer module and frequency speed control by asyn- chronous machine module and etc.Through comparison between output power spectrum chart of hybrid power system engine and actual test result of the original power system,energy-saving po- tentiality in one work cycle of the crane is analyzed.Power distri- bution between diesel engine and electric capacitor in the hybrid power system is analyzed and charging/discharging procedure of the capacitor is simulated and analyzed;energy-saving result of the new type hybrid power system is obtained.Application value of the hybrid power system is theoretically discussed.
