| 中文摘要 | 针对山东电网,提出了一种广域控制系统的设计和分析步骤。首先,需要对山东电网进行振荡稳定分析;然后,用伪随机二元信号探测和预测误差方法对系统进行降阶辨识,根据降阶辨识得到的主模比和留数指标来分别选择反馈信号和控制器地点;最后,控制设计问题就转化为带约束的非线性规划,可对多个控制器参数进行协调和优化。用山东电网仿真数据对广域阻尼控制系统进行验证的同时,也分析了它对本地模式的影响。仿真结果表明,该方法在阻尼山东电网的区间振荡和提高传输容量上均有效。; This paper proposes a systematic design procedure for wide-area damping control(WADC) system in Shandong power grid.In the first place,the oscillatory stability of the system is thoroughly analyzed.The low-order system models are identified using PRBS and PEM for the design and control purpose.Then the feedback signals and controller locations are properly determined based on the dominant mode ratio and the transfer-function model residues,respectively.Finally coordinated and optimized tuning of the multiple controllers' parameters is achieved via constrained nonlinear programming.The developed wide-area control scheme has been tested on the Shandong power grid.Its influence on local modes has also been analyzed.The simulation results have well demonstrated its effectiveness in damping inter-area oscillations and increasing across-region transfer capabilities for Shandong power grid. |
