摘　　要：以往的 HVDC系统控制研究采用的模型不够详尽 ,为了更真实地考察 HVDC系统的控制特性 ,文中采用详细模型模拟了直流线路动态及触发延迟。采用此详细模型后微分几何方法及逆系统方法不便应用 ,为此提出了非线性输出跟踪控制器设计的关联度方法 ,这种方法物理意义明确 ,数学推导简单 ,适用范围广。应用此方法设计了详细模型下 HVDC系统的非线性输出跟踪控制器 ,数字仿真表明所设计的这种 HVDC系统控制器效果良好 ,关联度方法是有效的。HVDC systems have not been simulated in detail in earlier studies on control of HVDC systems. In order to study the control characteristics of HVDC systems more practically, this paper simulates the dynamics of DC lines and firing delay in detail. Because it is difficult to apply differential geometry method and inverse system method to the detailed models of HVDC systems presented here, a new method RMD, namely the relation extent method, is presented. RMD is physically clear, mathematically straightforward and can be employed widely. By applying RMD, a nonlinear output-tracked controller for detailed models of HVDC systems is designed. Digital simulations indicate that the performance of this kind of controller for HVDC systems is pleasing and RMD is effect.
