    摘要:

    针对传统PI控制用于静止无功补偿器控制系统存在快速性和平稳性矛盾的问题,提出了一种改进型非线性度变换的PI控制器设计方法,分别在传统PI控制器的比例、积分环节之前加入不同非线性度的非线性变换环节以构成非线性PI控制,并将其应用于静止无功补偿器控制系统电压调节单元的设计。仿真结果表明,改进型非线性度变换PI控制可在一定程度上提高常规非线性度变换PI控制的响应速度和稳定性;与传统PI控制相比,基于改进型非线性度变换PI控制的静止无功补偿器控制系统具有响应速度快、超调量小、动态和静态稳定性好等优点。

    Abstract:

    Aimed at the problem of conventional PI controller with the contradiction between the rapid and smooth when it was used for the SVC control system, a design method of the improved nonlinear norm transformation PI controller was proposed. In front of the conventional PI controller’s proportion and integral, different nonlinear norm transformations were added to form nonlinear PI controller. Then, this nonlinear PI controller was used for the voltage regulator unit design in SVC control system. The simulation results showed that the improved nonlinear norm transformation PI controller has faster response speed and better stability than nonlinear norm transformation PI, in addition, the SVC control system based on improved nonlinear norm transformation PI controller has the advantages of faster response speed, smaller over-modulation, better static and dynamic performance comparing with conventional PI controller.
