摘要
风电机组存在随机性、波动性等问题给电网带来的安全隐患,因此随着风电机组并网规模的不断加大,如何更为准确快速地实现风电机组频率控制,实现风电机组并网稳定性成为亟待解决的问题。为了使学生更为准确地理解风电机组的调频控制策略,设计了以双馈风电机组(doubly-fedinductiongenerator,DFIG)为例的一次调频控制实验。首先,通过下垂控制方法对DFIG进行一次调频控制;其次,采用稳态及暂态调频相结合的方法,提高频率响应特性;最后,采用RT-LAB半实物仿真平台搭建DFIG控制实验架构,通过仿真分析与实验验证相结合的方法,验证所提方法对风电机组调频的响应能力。
Wind power generation has the safety risks brought by the randomness, volatility and other problems to the grid. Therefore, with the increasing scale of wind turbines, the question of how to control the frequency of wind turbines more accurately and quickly and realize the stability of grid connected wind turbines has become an urgent problem to be solved. In order to make students understand the frequency control strategy of wind turbine more accurately, a primary frequency control experiment is designed, which uses doubly-fed induction generator(DFIG) as an example. Firstly, the droop control method is used to control the primary frequency modulation of DFIG. Secondly, the combination of steady-state and transient frequency modulation is adopted to improve the frequency response characteristics. Finally, the RT-LAB hardware in the loop simulation platform is used to build the DFIG control experimental framework, and the response ability of the proposed method to wind turbine frequency regulation is verified by combining simulation analysis with experimental verification.
