中文摘要：
传统阻尼控制器参数设计方法依赖系统线性化模型，无法计及系统非线性因素的影响；信赖域法具备局部的超线性收敛性和总体收敛性。提出并实现了用于广域阻尼控制器结合参数设计的新方法，结合非线性时域仿真技术与信赖域方法。解决了优化目标函数构造、控制参数初值获取和信赖域法子问题模型获取3个子问题，实现了多运行方式下、多个广域阻尼控制器的参数协调优化。通过阻尼东北与华北、山东电网之间机电振荡的控制器参数优化验证了算法的有效性。对比单一方式下的优化参数，多方式下的联合优化参数对各种方式均有良好的控制效果。
英文摘要：
Traditional parameter design of damping controller depends on linear system model, without considering the impact of non- linear factor,however the trust region method has partial super-linear convergence and global convergence. The trust region method combined with non-linear time domain simulation technology is presented and implemented for the design of WADC （Wide -Area Damping Controllers）. The construction of optimal target function,the setting of control parameter initial valves and the establishment of trust- region sub- model are introduced to realize the para.meter coordination optimization of multiple controllers under different operating modes. The controller parameter optimization for damping the electromechanical oscillation among Northeast Power Grid,North China Power Grid and Sandong Power Grid verifies its effectiveness. Compared with mono- mode,the multi- mode parameter coordination optimization has better control effect for different operating conditions.
