[Abstract]:Energy crisis and environmental protection have become an important research topic in the world. In order to realize the national sustainable development, the industrial countries all over the world are actively researching and developing new energy sources and environmental protection and energy saving products. As a large energy user, port hoisting machinery has put forward the development direction of high efficiency and green. In view of the successful application of hybrid power technology in automobile, The research and application of hybrid power system in lifting machinery is more and more extensive. In this paper, the DC 90KW hybrid electric tire crane based on super capacitor developed by Wuhan University of Technology is taken as the research object. On the basis of analyzing the overall structure of the system and the working principle of each module, the mathematical model of each module is established, and the simulation model of each module is constructed by using SABER software, and the typical operating conditions of the system are simulated. Continuously optimize the control strategy of the system to achieve greater energy-saving effect. Firstly, the paper analyzes the related background of energy crisis and sustainable development, introduces the typical structure of hybrid power system and the corresponding control strategy of each structure, and analyzes the development of hybrid power technology in automobile industry and crane industry. The development of simulation technology is briefly introduced. Secondly, the composition and control system of 90KW DC hybrid tire crane based on super capacitor are introduced briefly, and the technical parameters of main power components of the system, including super capacitor, are analyzed.

Then, from the point of view of simulation, on the basis of analyzing the characteristics and working principle of each module of the system, we simplify each module reasonably, establish the mathematical model of each module, and in the SABER software, The simulation model of diesel engine model, super capacitor model, bidirectional DC/DC converter model and H-bridge chopper model, and the model of external excitation DC motor are constructed by using MAST language. Finally, the simulation model of crane hybrid power system is constructed by integrating all modules of the integrated system, and the simulation analysis of typical working conditions is completed. Through the comparison of simulation experiments, the fuel saving efficiency of the system is analyzed, and the optimization scheme of control strategy is put forward.
