基于STATCOM/BESS的风火打捆系统次同步振荡抑制研究
|
摘要
基于高压直流输电(HVDC)技术将风电与火电打捆运行已成为解决远距离输电需求的一种可行方案。为解决风火打捆经直流送出系统的次同步振荡问题,提出了一种基于储能型静止同步补偿器(STATCOM/BESS)的抑制方法。首先对STATCOM/BESS抑制次同步振荡的机理进行了分析;其次,基于广域测量系统(wide area measurement system,WAMS)设计出STATCOM/BESS关于风火打捆系统的次同步振荡抑制方法,在STATCOM/BESS电流内环控制回路上附加阻尼控制抑制多模态振荡,并采用改进粒子群算法(particle swarm optimization,PSO)对附加阻尼控制器参数进行协调优化。最后,基于PSCAD/EMTDC平台搭建了含STATCOM/BESS接入的风火打捆经直流送出系统仿真模型,对所提抑制方法的有效性进行仿真验证,结果表明该方法能有效抑制风火打捆系统中的次同步振荡问题,提高系统的稳定性。
Wind-thermal power bundled system with HVDC external transmission technology has become an ideal solution for long-distance transmission. To suppress the multi-modal sub-synchronous oscillation problem generated by the wind-thermal power bundled system,a suppression method based on the STATCOM/BESS is proposed. Firstly,the mechanism of STATCOM/BESS for suppressing SSO is analyzed. Secondly,based on wide area measurement system(wide area measurement system,WAMS),the STATCOM/BESS suppression method for the SSO of the wind-thermal power bundled transmission system is designed,adding damping control to suppress multi-mode oscillation on the STATCOM/BESS current inner loop control loop,and the parameters of the controller are coordinated and optimized using the improved particle swarm algorithm for additional damping. Finally,on the basis of PSCAD/EMTDC platform,the simulation model of the wind-fighting baling system with STATCOM/BESS access is established. The effectiveness of the proposed suppression method is verified by simulation. It is shown by the result that the suppression strategy can effectively suppress SSO of the DC delivery system and improve the operational stability of the system.
