双馈风力发电系统模拟实验平台的研制

摘要

The wind energy is one of the fastest growing and most competitive new energy now,it’s quite necessary to develop an experimental platform which can be used for the scientific research and teaching on wind power technology in the laboratory environ-ment.This paper analyzes the characteristics of different wind velocities and wind turbines,proposes a physical model which fit the sci-entific research and teaching,developes a simulated doubly -fed wind power system experimental platform and the capacity of the mod-el is 10kW,The platform can run independently or connect with the power system dynamic simulation system,and can be connected to the WDT -III power system comprehensive experimental teaching system which is widely used in the national universities.The experi-ment results show that the dynamic characteristic of the model is consistent with the theory characteristic of the wind turbine,and can be used for the research and teaching experiment,the experimental platform has been applied in more than ten scientific research insti-tutions and colleges.%风能是目前发展最快、最具竞争力的新能源之一。开发一种在实验室环境下进行风电技术研究和教学的实验平台是非常必要的。该文分析研究了多种风速和风力机特性，提出了一种适合科研和教学实验的物理模型，研制了一套10 kW模拟双馈风力发电系统实验平台。该平台可以独立运行，也可以与电力系统动态模拟系统相连接，还可以接入到全国高校广泛应用的 WDT －III 电力系统综合实验教学系统中进行实验。实验研究结果表明，该模拟系统的动态特性与风机的理论特性相吻合，可用于风力发电技术研究和教学实验。该实验平台已在全国10多所科研院所和大专院校得到了应用。
