【摘要】：隨著能源可持續(xù)發(fā)展概念的深入,風力機組發(fā)電作為可再生能源得到了飛速的發(fā)展。風電機組系統的仿真系統在風力發(fā)電機組整個系統的分析,在發(fā)電量的分析以及電網的總能量的分析過程中都起到了舉足輕重的地位。本論文首先介紹了一下開發(fā)工具和語言,開發(fā)語言首先是Fortran語言,來進行科學計算以及算法方面的代碼編寫。然后是C++,用C++語言在MFC的環(huán)境下進行Fortran語言代碼的調用,具體方法論文中會進行介紹。主要是運用VS2008這個開發(fā)平臺進行開發(fā)的。介紹完之后,從技術、操作和經濟方面對這個軟件進行了可行性的分析。接著分析風電機組的工作原理并根據原理進行了風力機的建模,這樣可以更加深刻的理解仿真軟件中涉及到的各個參數所代表的含義以及它們的作用。然后就對仿真軟件的整體開發(fā)進行了概要設計,對后處理軟件進行了詳細設計,從功能和結構的方面,并對后處理中涉及到的各個模塊也進行了詳細設計。最后,在MFC的環(huán)境下,對后處理軟件可視化界面的開發(fā),最后在系統的實現中將后處理軟件的工作結果呈現出來。仿真軟件中,結合GL標準對風況和波浪進行綜合分類,共分成了958種極限工況和68種疲勞工況,對相應的風況和波浪進行仿真研究,并對各個工況進行載荷和負載的仿真研究,盡力模擬出接近實際的風機載荷。這個部分的設計提供了一種計算海上以及陸上風電機組載荷相關的方法,并可以得到整個風機系統的載荷,為風機重要零部件的有限元分析和優(yōu)化設計提供了負載根據。最后,對仿真后的數據進行處理,實現圖形顯示。
[Abstract]:With the deepening of the concept of energy sustainable development, wind power generation as a renewable energy has been rapidly developed. The simulation system of wind turbine system is analyzed in the whole wind turbine system. It plays an important role in the analysis of power generation and the analysis of the total energy of power grid. This paper first introduces the development tools and languages, first of all, the development language is the Fortran language. Then C, using C language to call the Fortran language code in the MFC environment, Specific methods will be introduced in the paper. Mainly using the VS2008 development platform for development. After the introduction, from the technology, The feasibility of the software is analyzed in terms of operation and economy. Then the working principle of wind turbine is analyzed and the model of wind turbine is built according to the principle. In this way, we can have a deeper understanding of the meaning of the parameters involved in the simulation software and their functions. Then, the overall development of the simulation software is outlined and the post-processing software is designed in detail. From the aspects of function and structure, the modules involved in post processing are also designed in detail. Finally, in the environment of MFC, the visual interface of post processing software is developed. In the simulation software, combined with GL standard, the wind condition and wave are classified synthetically, and a total of 958 kinds of limit working conditions and 68 kinds of fatigue conditions are divided. The corresponding wind and wave are simulated, and the load and load are simulated. The design of this part provides a method for calculating the load correlation of offshore and onshore wind turbines, and the load of the whole fan system can be obtained. It provides the load basis for the finite element analysis and optimization design of the important parts of the fan. Finally, the simulation data are processed to realize the graphic display.
