摘 要

随着科技的发展和需求的变化,移动式储能脉冲电源的研究和应用逐渐兴起。由于移动式储能电源对小体积、大功率的要求,飞轮储能技术逐步应用于脉冲功率电源,本文所要研究的基于感应子发电机的电容充电脉冲电源系统正是利用的感应子发电机作为飞轮储能装置。该脉冲电源系统具有功率高,体积重量小,可以重复频率充电的优良性能,能够很好地应用于野外移动式的工作环境。

第三章通过采用发电机、充电主电路以及电容负载联合仿真的方式,对比几种常见电容充电主电路的拓扑结构充电性能优缺点,并结合感应子发电机的特殊要求和系统性能的要求进行综合分析,最终确定三相半控整流的主电路拓扑结构。同时,本章还就充电回路中各参数对系统充电性能的影响进行了研究。

第四章对比方法,对感应子发电机带整流容性负载的充电过程进行了瞬态分析通过搭建数学模型,将换流过程分为了三种工作模态,进而通过对工作模态的进一步分析,得到了换流过程对电源系统充电性能的影响,为后期提升充电性能,发电机与充电器的一体化设计提供了理论支撑。

第五章根据设计,确定了系统主要开关器件的参数和型号,通过对小型样机系统进行了实物试验,对不同条件下,电源系统的工作性能进行了仿真研究。通过对比分析发现实验结果与前文中的仿真结果和理论分析的结果相差不大,表明了前文理论分析和数学计算的正确性。

通过以上内容,本文完成了对高功率重频快速充电电源中主电路的设计和研究,搭建了仿真模型,并进行了实物试验的验证。

Abstract

With the development of science and technology and changes in demand, mobile energy storage pulse power research and application gradually rise. Due to the small size and high power requirements of the mobile energy storage power supply, the flywheel energy storage technology is gradually applied to the pulsed power supply. In this paper, pulse-CCPS system with a high-voltage generator-homopolar inductor alternator (HIA) is a flywheel energy storage device.The pulse power system has a high power, small size, can repeat the frequency of charging the excellent performance, can be well applied to the field of mobile work environment.

In this paper, the main part of the charging circuit of the capacitor charging pulse power system based on the induction generator is studied by means of simulation. The determination and design of the topology of the charging circuit are closely related to the performance of the charging power supply. Different topologies are used to influence the charging efficiency and design difficulty.

The second chapter analyzes the working principle and mathematical model of the induction generator. Because of the analysis of the motor flux linkage model in this chapter, it is found that the special cogging structure of the induction sub-motor makes the inductance matrix harmonic component negligible. Therefore, the model of the sensor generator with harmonic components is constructed. By discussing the induction generator The simplified equivalent model of the induction generator is obtained by using the condition of double reaction theory.

In the third chapter, the advantages and disadvantages of the topological structure charging performance of the main circuit of the main capacitor are compared with the requirements of the special requirements of the induction generator and the performance of the system by using the generator, the charging main circuit and the capacitor load combined simulation. Comprehensive analysis, and finally determine the three-phase semi-rectifier rectifier main circuit topology. At the same time, this chapter also studies the influence of the parameters of the charging circuit on the charging performance of the system.

In the fourth chapter, the transient process of the charging process with the rectified capacitive load of the induction generator is analyzed. By constructing the mathematical model, the commutation process is divided into three working modes, and then through the further analysis of the working mode , The effect of the commutation process on the charging performance of the power supply system is obtained, which provides theoretical support for the later charging performance and the integrated design of the generator and the charger.

In the fifth chapter, the parameters and models of the main switching devices are determined according to the design. Through the physical test of the small prototype system, the working performance of the power system under different conditions is simulated. Through the comparative analysis, it is found that the experimental results are not the same as those of the previous simulation results and the theoretical analysis, which indicates the correctness of the previous theoretical analysis and mathematical calculation.

Through the above contents, this paper completes the design and research of the main circuit in the high power recharging fast charging power source, builds the simulation model, and carries on the physical test verification.
