【摘要】 为了进一步改善新型直流输电系统的控制性能,本文通过总结采用新型换流变压器及其相应感应滤波方式的直流输电系统的控制特性,在此基础上,将非线性控制理论中逆系统方法设计控制器的理论引入到新型直流输电系统的控制策略中,提出了采用基于逆系统方法的新型直流输电系统换流器一般非线性控制方式,并相应地设计了基于逆系统方法的整流侧定电流控制器及逆变侧恒定越前角控制器。通过对一具体的新型直流输电模拟系统控制性能进行仿真实验,将所设计的控制器与传统的直流输电PID控制器相比较,以验证新型直流输电系统采用基于逆系统方法的一般非线性控制器所具有的良好的控制性能。更多还原

【Abstract】 In order to further improves the new direct current transmission system the control performance,this article uses through the summary new trades changes the depressor and its the corresponding induction filter way direct current transmission system control characteristic,in this foundation,the counter system approach designs the non-linear control theory in the controller the theory to introduce the new direct current transmission system in the control strategy,proposed uses based on the counter system approach new direct current transmission system converter general non-linearity control mode,and correspondingly designed has decided the electric current controller and the contravariant side constant lead angle controller based on the counter system approach rectification side.Through carries on the simulation experiment to a concrete new direct current transmission analogous system control performance,will design the controller and the traditional direct current transmission PID controller will compare,will confirm the new direct current transmission system to use the good control performance which will have based on the counter system approach common non-linear controller.更多还原
