【摘要】 随着经济的增长,全球各国对能源的需求也日益增加,同时人们对环境保护也日益重视,人们迫切需要可再生能源。本文根据风光互补发电系统的结构特点,结合代理控制技术,完成风光互补发电的控制。采用DSP2821为控制器,通过PWM开关电源进行电压变换,满足系统各部分供电需求。整个系统工作正常、稳定。论文首先介绍了风光互补发电系统的整体结构,并分别阐述了风力发电、太阳能发电和蓄电池充放电原理及相应的电路拓扑的选择,提出了系统追求的目标。然后,介绍了代理的概念、结构和求解方式。最后,分别对风力发电、太阳能发电和蓄电池充放电三部分建立了代理结构模型。进而,对太阳能发电选择的Boost电路拓扑,进行了电路参数的设计、连续小信号模型的建立,并建立传递函数,然后进行电路补偿的设计。对风力发电选择的Buck-Boost电路拓扑,进行了电路参数的设计并根据传递函数进行了电路补偿的设计。接着,又阐述了铅酸蓄电池的特性及蓄电池的充电方法,并对充放电部分选择的Buck-Boost双向变换电路进行了介绍,并对Buck电路进行了电路参数和电路控制方法的设计。由于补偿的是模拟控制器,文中又给出了模拟控制器的数字化方法。最后,阐述了在代理控制下的软件设计流程,给出了部分辅助电路和波形图,经过波形的分析表明系统工作稳定、可靠。本论文详细论述了小型风光互补发电系统的整个设计过程,引入了代理机制,为新能源发电开拓了新思路。其中,代理模型的建立为多风机、多太阳能板联合发电提供了框架结构。更多还原

【Abstract】 With economic growth, countries around the world demand for energy urgently. At the same time, it is also increasing emphasis on importance of environmental protection. Renewable energy sources are urgently needed. According to the structural characteristics of wind&PV power supply and agent control technology, it completes the control of wind&PV power supply.In this paper, first it introduces the overall structure of hybrid power systems, and then expounds wind power generation, solar power generation and battery charging and discharging principles. It proposes the aims of system and corresponding choice of circuit topology. Then, it introduces the concept, structure and solution methods of agency. Finally, it establishes the agent model of the three parts.Furthermore, it chooses Boost circuit topology to meet the demand of solar power generation, and designs the circuit design parameters, establishes continuous small-signal model, and establishes the compensation circuit design.It describes the characteristics of lead-acid batteries and battery charging method, and introduces Buck-Boost circuit. It also designs the Buck circuit design parameters, and establishes the compensation circuit design. Because operation is an analog controller, this paper introduces digital simulation method of the controller.At last, it elaborates the software flow pattern on the agent control, and Parts of the auxiliary circuit. After waveform analysis it shows that system is stable and Reliable.This paper discusses the design process of small-scale wind&PV power supply systems, and introduces of the agent mechanism. It develops a new way for energy power generation. The agent model provides a framework structure for the coordination power supply of more fans and more solar panels.更多还原
