中文摘要	随着风力发电的飞速发展，在实验室搭建风力发电模拟平台已成为研究风力发电运行特性的重要方法，对研究风力发电和微型电网都有着重要的意义。风力机软件模拟器为风电模拟平台的重要组成部分，风电模拟平台由上位机、原动机、发电机、并网装置构成，原动机用来模拟风速经过风力机、低速轴、齿轮箱到达高速轴的转矩，转矩值的大小由上位机软件模拟器实时计算得到。风电模拟平台的模拟准确性取决于风力机软件模拟器的准确性，因此，风力机软件模拟器的建模方法、数值计算流程和软件设计方案需要准确可靠。 本文围绕风力发电系统的建模展开，对风电系统的各个组成部分分别建立了数学模型，建立的模型包括风速模型、风力机稳态模型、风力机动态模型和传动系统模型，其中风力机模型的建模理论依据为动量叶素理论(Bladed Element Momentum)。运用Visual C++开发工具，以理论模型为基础，对各模块进行开发测试和集成，编写出完整的风力机模拟软件，并利用SQL Server建立数据库以存储软件运行中需要用到的数据，将软件的运行结果与风力机商业软件Bladed的运行结果进行了对比，误差较小，验证了本文建模方法和计算流程的可行性和准确性，软件集成通信模块后用于风电模拟平台的实验，实验结果表明，软件运行稳定可靠，能模拟多种风速、不同模型下的风力机运行特性。 With the rapid development of wind power production, establishing platform for wind power characteristics and performance research in laboratory has become an important method, and has great significance for both wind power research and micro-grid research. Wind turbine software is an important part of wind power simulation platform. The wind power simulation platform includes upper computer, prime mover, generator and cut-in device. The prime mover provides the torque in simulation, which is calculated by upper computer wind turbine software real-timely. The simulation accuracy of platform depends on the accuracy of wind turbine software, so the modeling methods and the software design scheme need to be accurate and reliable. In this paper, including wind speed model, steady model of wind turbine, dynamic stall model of wind turbine, transmission system model. The wind turbine model established in this paper based on bladed element momentum (BEM) theory. With the Visual C++ development tool, based on those theory models, it has achieved development; test and integration of the wind turbine software. SQL Server is used to establish database which store data that needed in this software. Compared the software developed in this paper with GH Bladed, an integrated software package for wind turbine performance and loading calculations. The results show that the models developed in this paper is quite accurate compared with the commercial software. Integrated the communication module, the wind turbine software can be used in the wind power simulation platform experiments, the experimental results show that the wind turbine software is stability and reliability, and can simulate wind power characteristics and performance of different wind power systems.
