中文摘要：
面对低频振荡阻尼控制器和输入信号多样化的复杂局面,如何优化协调阻尼控制器的输入信号和安装地点值得研究。为此,通过理论推导得出控制敏感因子指标用以指示阻尼控制器最优安装位置和输入信号;进一步提出了基于控制敏感点的电力系统稳定器（PSS）与直流附加阻尼控制的协调优化策略,给出了不依赖系统精确数学模型的实用化计算步骤。通过川渝电网多种运行方式验证,理论计算结果与仿真结果一致,结果表明控制敏感因子能够正确指示阻尼控制器的最优安装位置和输入信号,PSS与直流附加阻尼控制通过相互协调可以全面抑制低频振荡,提高系统运行稳定性。
英文摘要：
In the face of diversity of low frequency oscillation damping controller and the input signal, it is worthy of studying optimal input signal and installation place of damping controller. Consequently, we obtained a control sensitive index by theoretical derivation to indicate the optimal damping controller installation position and the input signal, put forward a coordination optimization strategy of power system stabilizer（PSS） and HVDC damping low frequency oscillation based on control sensitive points, and presented calculation steps which do not depend on the accurate mathematical model of the system. Through verification under a variety of Sichuan Chongqing power grid operation modes, the theoretical results are in agreement with the simulation results. The results show that optimal control sensitive factor can indicate the damping controller installation position and the input signal correctly. Coordination optimization control strategy between PSS and HVDC can fully inhibit low frequency oscillation and improve stability of the system.
