摘　　要：根据相间功率控制器(IPC)功率控制特性,通过对比调谐型IPC与非调谐型IPC调节功率的灵敏度,说明了调谐型IPC对联络线功率的调节能力比非调谐型IPC强。基于微分几何仿射非线性控制理论,推导出调谐型可控相间功率控制器(TCIPC)仿射非线性系统模型,并根据状态反馈精确线性化方法,设计了调谐型TCIPC非线性控制器。以单机无穷大系统中串入调谐型TCIPC为例进行仿真。结果表明:采用所提出的控制方法设计的调谐型TCIPC控制器,在系统发生大干扰后具有良好的阻尼性能,可以起到提高系统暂态稳定性的作用。Based on the active power control characteristic of IPC（Interphase Power Controller） , the sensitivity of power regulation is compared between tuned IPC and non-tuned IPC,which shows the tieline power regulation capability of tuned IPC is better than that of non-tuned IPC. The model of tuned nonlinear system is derived based on the theory of affine nonlinear control for the TCIPC（Thyristor Control lnterphase Power Controller） and the single-machine infinite-bus system with serial tuned TCIPC is simulated,which shows the tuned TCIPC designed has excellent damping performance during serious system oscillation,improving the system transient stability remarkably.
