摘要
风电作为新能源发电技术,具有清洁无污染、分布广泛、能源可再生等优点得到广泛应用,对构建以新能源为主的新型电力系统具有重要意义。由于风能的波动性和随机性,风电大规模接入增大了电网系统净负荷波动幅值和速率,影响电网频率稳定性。以传统永磁直驱风电系统为基础,基于飞轮储能技术,建立一种具有高功率密度的直驱式风电调频系统,并基于MATLAB/Simulink系统搭建仿真模型进行测试,验证了系统的可行性。
As a new energy power generation technology,wind power is widely used because of its advantages of clean and pollution-free,wide distribution and renewable energy,which is significant to the construction of a new power system based on new energy.However,due to the volatility and randomness of wind energy,the large-scale access of wind power will increase the amplitude and rate of net load fluctuation of the power grid system,affecting the stability of the power grid frequency.Based on the traditional permanent magnet direct drive wind power system and combined with flywheel energy storage technology,a direct drive wind power frequency modulation system with high power density is established,and the simulation model is built in MATLAB/Simulink system for testing,verifying the feasibility of the system.
