为提高电力系统稳定器的动态性能及鲁棒性，提出一种基于协同控制理论的分散非线性电力系统稳定器(power system stabilizer based on synergetic control theory，SPSS)设计方法。首先针对同步发电机及励磁系统模型，根据协同理论，构造出合适的流形，然后推导出SPSS的控制规律，进一步实用化后，得到一种基于协同控制理论的实用的SPSS，由于SPSS的所有输入信号均为本地易测量信号且与网络参数无关，从而能实现分散控制。最后，将所设计的SPSS用于3机6节点电力系统进行小扰动和大扰动仿真验证。仿真为提高电力系统稳定器的动态性能及鲁棒性，提出一种基于协同控制理论的分散非线性电力系统稳定器(power system stabilizer based on synergetic control theory，SPSS)设计方法。首先针对同步发电机及励磁系统模型，根据协同理论，构造出合适的流形，然后推导出SPSS的控制规律，进一步实用化后，得到一种基于协同控制理论的实用的SPSS，由于SPSS的所有输入信号均为本地易测量信号且与网络参数无关，从而能实现分散控制。最后，将所设计的SPSS用于3机6节点电力系统进行小扰动和大扰动仿真验证。仿真结果表明，与常规的相位补偿型的PSS相比，所提出的SPSS能够在较大的运行范围内向系统提供充分的阻尼，并对模型误差不敏感，具有很好的鲁棒性。“,”A novel decentralized nonlinear power system stabilizer based on synergetic control theory (SPSS) was proposed in order to improve dynamic performance and robustness of the power system. A manifold was established according to the model of synchronous generator and excitation system firstly. Then the control law of the proposed SPSS was deduced using synergetic control theory and a practical SPSS was obtained subsequently. Since all of the input signals of SPSS were local measurements and independent of the parameters of the power network, the decentralized control strategy could be achieved. Simulation on a three-machine six-bus power system under small and large disturbances demonstrates that the proposed SPSS can provide stronger damping to the system than conventional PSS in a wide range of operating conditions. Moreover, the proposed SPSS has excellent robustness because its performances are insensitive to the accuracy of the system parameters.
