【摘要】：风能本身就是一种清洁资源,在使用时不会对环境带来任何污染,并且风力发电设施的建设工期较短,占地面积也较少,无论从哪种效益类型来看,该能源都具有非常明显的优势,正因为优势较为明显才受到了世界上多个国家的关注和发展。西方的一些发达国家在风力发电这一领域做出了大量的研究,并投入了大量的人力与物力,经过长时间的发展,已经取得了一定的研究成果,建立了预测风能的专业系统,针对风力发电在运行过程中可能会存在的问题,提出了具体的解决措施,并采用了新型的材料,研究出了具备专业技术和能力的发电系统,同时对控制系统进行了完善,改变了原有的单一控制的模式,将自动化技术引入其中,最大程度上提升了发电的效率和能力。变桨距风力发电机组是通过其内部的结构运行对功率进行调节,调节的主要是机组的额定功率,当机组在运行时,功率过大或过小时,内部结构都会自动地进行调整。从世界上所研发的风力机组来看,主要运用的技术有两种,变桨距技术和定桨距技术,而具体采用哪种技术则是由机组的实际容量决定的。风力发电的发展前景是非常广阔的,大型风力发电装置的应用能够提升风力发电的功率,必将引领世界风力发电产业的主潮流,风力发电技术的研究也成为世界新能源研究的焦点而被重视。本文主要通过对风力发电机组控制技术分析了解的基础上,比较分析了两种典型控制技术并重点研究变桨距风力发电机组的变距控制、最优转速控制和最大功率点跟踪控制。
[Abstract]:Wind energy itself is a kind of clean resource, it will not cause any pollution to the environment when it is used, and the construction period of wind power facilities is shorter and the area is less, no matter what kind of benefits, This energy source has very obvious advantages, which have attracted the attention and development of many countries in the world because of its obvious advantages. Some developed countries in the West have done a lot of research in the field of wind power generation. And has invested a lot of manpower and material resources, after a long period of development, has made certain research results, established the professional system of wind energy prediction, aiming at the possible problems in the operation of wind power generation, The concrete solution is put forward, and new materials are used to study the power generation system with professional technology and capability. At the same time, the control system is perfected, and the original single control mode is changed. The introduction of automation technology can improve the efficiency and ability of power generation to the maximum extent. The variable pitch wind turbine regulates the power through its internal structure operation, the main regulation is the rated power of the unit. When the unit is in operation, if the power is too high or too small, the internal structure will be automatically adjusted. From the point of view of the wind turbines developed in the world, there are two main technologies used: variable pitch technology and fixed pitch technology. The actual capacity of the unit determines which technology to adopt. The development prospect of wind power generation is very broad. The application of large-scale wind power generation equipment can enhance the power of wind power generation. It will lead the world wind power industry, and the research of wind power technology will become the focus of the new energy research in the world. Two typical control techniques are compared and analyzed, and the variable pitch control, the optimal speed control and the maximum power point tracking control of the variable pitch wind turbine are studied.
