| 摘 要： | HVDC系统的常规控制普遍采用PI控制策略,该策略是基于固定增益的稳定运行状态进行控制器设计的.由于HVDC系统的响应随运行状态的变化而改变,使得PI控制器的性能很难实现最优.本文基于计算智能理论(Computational Intelligence,CI),将粗糙集理论与粒度计算技术相结合,提出了一种新型的高压直流输电自适应控制器,该控制器可根据HVDC系统运行参数的动态变化对增益大小进行调节,从而使系统的控制性能得到优化,仿真试验结果证明了这一结论.

| Abstract: | A proportional integral(PI) control strategy is commonly used for constant current and extinction angle control in an HVDC system.A PI control strategy is based on a static design where the gains of a PI controller are fixed.Since the response of a HVDC plant dynamically changes with variations in the operating point,a PI controller's performance is far from optimal.The contribution of this paper is the presentation of the design of a Computational Intelligence based control scheme.Experimental results that compare the performance of the adaptive control and PI control schemes are also given. |
