摘要:
针对海上风电场柔性直流输电(voltage source converter high voltage direct current,VSC- HVDC)系统传统矢量控制中,PI参数难以整定、需要调制器以及难以实现多目标优化等问题,提出 了一种基于有限控制集模型子贞测控制(finite control set model predictive control,FCS-MPC)的新型海 上风电VSC-HVDC并网控制策略。该方法结合并网逆变器的离散数学模型,通过电流误差构造价 值函数,以价值函数为优化目标,预测并网逆变器未来时刻的开关状态;为避免计算时间延时并实 现多目标优化,引入延时补偿和权重系数,产生最优开关组合触发并网逆变器。在Matlab/SIMU- LINK中建立风电并网系统的仿真模型,并采用FCS-MPC和传统PI控制两种方法实施并网控制, 通过对风电场功率波动及电网发生故障等多种运行环境进行仿真,结果有效验证了所提出的FCS- MPC方法应用于VSC-HVDC海上风电场并网系统对直流电压的控制能力和故障恢复能力。
Abstract:
To overcome the problems such as PI parameters tuning,modulator requirement and multi-objective optimization in traditional vector control strategy,a FCS-MPC strategy of grid-connected inverters for offshiore wind farm VSC-HVDC was proposed. Based on the discrete mathiematical model of grid-connected inverters,this strategy can predict the switching states of grid-connected inverters in future moments by considering the current error based value function as optimization objective. To avoid the computing
time delay and to achieve multi-objective optimization,delay compensation and weighting coefficients were introduced to generate optimal switch combinations to drive the inverters. Simulation models using FCS-MPCand traditional PI controller respectively for wind power integration were established in MAT-LAB/Simulink. By means of simulations under various situations such as wind power fluctuations, grid fault occurrences!etc,it validates the desirable performances of the offshore wind farm VSC-HVDC with the proposed FCS-MPC in DC voltage control and fault recovery.
