| 中文摘要 | 应用能量整形 IDA PBC方法设计了针对电力系统大干扰的可控制动电阻(TCBR)的闭环暂态稳定控制器, 能量整形IDA PBC方法直接使用系统能量作为存储函数, 物理意义明确, 较其它非线性控制器结构简单, 并避免了可能产生的不期望的高增益问题。由于设计中完整地保留了系统非线性结构, 不需进行任何线性化处理, 较各种线性化设计方法具有更强的鲁棒性, 适应系统模型和参数不精确程度效果较好。建立了适合能量整形和考虑系统调节动态的简化TCBR三阶模型, 首次提出了用于求解能量整形匹配 PDE的待定系数法用以有效设计 TCBR 闭合连续暂稳控制器,并详细探讨了求解匹配 PDE待定系数法的理论基础, 文中给出的仿真算例表明所提出的控制器有效可行。; In this paper, a novel TCBR controller is presented for power system transient stability improvement via energy-shaping IDA-PBC method. The proposed IDA-PBC passive stabilizer uses the real energy function of power system as the close-loop Hamiltonian function and in simple structure. Since the system nonlinear characteristics are completely preserved, the proposed TCBR IDA-PBC controller is more robust than linear control method. Also a feasible scheme is proposed to employ the control strategy after considering the physical structure of power system. The main contributions include the establishment of a three-order simplified TCBR model,which is more suitable for energy-shaping method and a consideration of the dynamic effect of TCBR regulation as well. Furthermore, a novel IDA-PBC match PDE solution method is applied to derive the close-loop control law for TCBR. Based on the introduction of a virtual coupling between the electrical and the mechanical dynamics of the power system and the derivation of a new Lyapunov function. The OMIB model is applied in this paper and the multi-machine case will be presented on the next paper. The proposed strategy and method are proved to be effective by the results of digital simulation research done in this paper.; 国家重点基础研究基金 (G1998020315); 国家杰出青年科学基金资助项目 (59825104) |
