摘要:近年來隨著經(jīng)濟(jì)的不斷發(fā)展和人們生活水平的不斷改善，在世界范圍內(nèi)石油、煤炭這些不可再生資源的使用量已經(jīng)大大超過環(huán)境所能承受的范圍，燃燒發(fā)電廠產(chǎn)生的污染物也對地球環(huán)境產(chǎn)生了負(fù)影響。然而風(fēng)能是一種清潔、可再生的能源，在發(fā)電這一領(lǐng)域具有巨大的開發(fā)潛力和商業(yè)活力。隨著科技的不斷進(jìn)步，計算機(jī)和可編程控制的科研水平在提升，這對于風(fēng)電控制的研究又提供了新的途徑。針對風(fēng)能具有隨機(jī)性、不確定性的特點，本文用西門子可編程控制器S7-200來對風(fēng)力發(fā)電進(jìn)行控制。主要內(nèi)容包括電氣原理圖和設(shè)計流程圖的繪制，PLC、電氣元件的選型，發(fā)電機(jī)組啟動控制、偏航控制、溫度控制和變壓器控制等。在論文中給出詳細(xì)的控制原理解釋和各模塊的功能介紹，并配有每一模塊的控制程序。最后進(jìn)行相關(guān)調(diào)試和仿真，利用STEP7-Micro/WIN32編程軟件對PLC程序進(jìn)行調(diào)試、仿真運(yùn)行和在線診斷等，使仿真結(jié)果滿足設(shè)計要求。 關(guān)鍵詞：風(fēng)力發(fā)電；可編程控制器；偏航；溫度控制
Abstract:In recent years, with the continuous development of the economy and people’s living standards continue to improve, in the scope of world petroleum, oil and coal these non-renewable resource consumption was significantly more than the environment can stand. Combustion power generation of pollutants generated also produced negative effect to the environment of the earth. However, the wind energy is a clean, renewable energy power generation, it has tremendous development potential and business activity in this area. With the progress of science and technology, computer and programmable control of the level of scientific research in ascension, for wind power control research provides a new way. In this paper, aiming at these characteristics of uncertainty and randomness wind energy, we can use Siemens programmable controller S7-200 to wind power control. The main contents include drawing the corresponding electrical schematic diagram and the flow chart, selecting the PLC and electrical components, turbine start-up control, yaw control, temperature control, transformer control and so on. In this paper, it gives detailed explanation of the control principle and the function of each module and control program. Finally, it needs testing and simulation, using of STEP7-Micro/WIN32 programming software for the PLC program debugging, simulation and online diagnosis and so on, so that the simulation results meet the design requirements. Key words：wind power generation; programmable controller; yaw; temperature control
