| 摘 要： | 介绍了关联测量分散控制基本原理,针对多馈入交直流系统,采用关联测量的分散协调控制原理推导直流线路的附加控制策略,提出基于关联测量矢量直流系统附加控制的分散协调控制策略.该方法只需要当地信号,控制结构简单,易于实现.算例结果表明,该方法能够充分利用HVDC的快速响应能力,实现多条直流线路的分散协调控制、功率支援和电压保持,具有很好的鲁棒性并能提高系统的稳定性.

| Abstract: | Based on correlative measured vector, in this paper, a new decentralized coordinated control method is presented for multi-infeed HVDC system. First, a correlative measured state space model of multi-infeed HVDC system is developed. Based on this model, correlative measured decentralized coordinated control law is derived, which only require local information and is a simple configuration. The simulation results show that the proposed control law can improve the performance of multi-infeed HVDC system by use of the fast response and short time over load capability of HVDC links. |
