【摘要】：風(fēng)能本身就是一種清潔資源,在使用時(shí)不會(huì)對(duì)環(huán)境帶來任何污染,并且風(fēng)力發(fā)電設(shè)施的建設(shè)工期較短,占地面積也較少,無論從哪種效益類型來看,該能源都具有非常明顯的優(yōu)勢(shì),正因?yàn)閮?yōu)勢(shì)較為明顯才受到了世界上多個(gè)國家的關(guān)注和發(fā)展。西方的一些發(fā)達(dá)國家在風(fēng)力發(fā)電這一領(lǐng)域做出了大量的研究,并投入了大量的人力與物力,經(jīng)過長時(shí)間的發(fā)展,已經(jīng)取得了一定的研究成果,建立了預(yù)測(cè)風(fēng)能的專業(yè)系統(tǒng),針對(duì)風(fēng)力發(fā)電在運(yùn)行過程中可能會(huì)存在的問題,提出了具體的解決措施,并采用了新型的材料,研究出了具備專業(yè)技術(shù)和能力的發(fā)電系統(tǒng),同時(shí)對(duì)控制系統(tǒng)進(jìn)行了完善,改變了原有的單一控制的模式,將自動(dòng)化技術(shù)引入其中,最大程度上提升了發(fā)電的效率和能力。變槳距風(fēng)力發(fā)電機(jī)組是通過其內(nèi)部的結(jié)構(gòu)運(yùn)行對(duì)功率進(jìn)行調(diào)節(jié),調(diào)節(jié)的主要是機(jī)組的額定功率,當(dāng)機(jī)組在運(yùn)行時(shí),功率過大或過小時(shí),內(nèi)部結(jié)構(gòu)都會(huì)自動(dòng)地進(jìn)行調(diào)整。從世界上所研發(fā)的風(fēng)力機(jī)組來看,主要運(yùn)用的技術(shù)有兩種,變槳距技術(shù)和定槳距技術(shù),而具體采用哪種技術(shù)則是由機(jī)組的實(shí)際容量決定的。風(fēng)力發(fā)電的發(fā)展前景是非常廣闊的,大型風(fēng)力發(fā)電裝置的應(yīng)用能夠提升風(fēng)力發(fā)電的功率,必將引領(lǐng)世界風(fēng)力發(fā)電產(chǎn)業(yè)的主潮流,風(fēng)力發(fā)電技術(shù)的研究也成為世界新能源研究的焦點(diǎn)而被重視。本文主要通過對(duì)風(fēng)力發(fā)電機(jī)組控制技術(shù)分析了解的基礎(chǔ)上,比較分析了兩種典型控制技術(shù)并重點(diǎn)研究變槳距風(fēng)力發(fā)電機(jī)組的變距控制、最優(yōu)轉(zhuǎn)速控制和最大功率點(diǎn)跟蹤控制。
[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.
