组合数学研究的主要内容是按照一定规律安排某些事物的数学问题。基本问题：存在问题；基本问题；构造问题：最优化问题-Combinatorics of the main contents of the arrangements in accordance with the laws of certain things, certain mathematical problems. Basic question: there is a problem basic issues structural

在风力发电的模拟系统中,风速模拟是一个重要的环节,正确的风速模型不仅能够很好的 反应实际风速变化情况,而且能够给风力发电系统研究提供正确的源参数。本文用 Matlab/Simulink建立了风速组合数学模型,该模型将风速分为基本风速、阵风、渐变风速和噪声风 速4部分,仿真结果表明该模型能够理想的反应实际风速 -Wind speed simulation is an important part in the simulation of wind power generation

组合数学（combinatorial mathematics），又称为离散数学。狭义的组合数学主要研究满足一定条件的组态（也称组合模型）的存在、计数以及构造等方面问题。-Combinatorial Mathematics (combinatorial mathematics), also known as discrete mathematics. Narrow combination of mathematical research configuration to meet certain
