| 摘 要： | 提出基于虚拟阻抗的动态等效模型在线修正方法。首先，指出等值过程中不合理的聚类算法、对时变系统的定常化假设是误差主要来源。接着，提出通过等效模型的在线修正以克服系统时变性所导致的误差。由于等效模型可调参数过多，难以对所有参数进行调整。为此，在等效发电机、等效电动机节点引入附加虚拟阻抗，应用蚁群优化算法进行调节，以实现边界点最佳功率匹配，并利用广域测量系统(wide area measurement system，WAMS)提供的实测数据对动态等效模型进行定时修正。最后，IEEE 10机39母线系统的等值计算结果表明：算法较好地改进了动态等效模型的静态精度与暂态精度，提高了模型的强壮性。

| Abstract: | A novel method of online adjustment of dynamic equivalent model was proposed in this paper.Firstly,it was pointed out that the unreasonable aggregation algorithm and constant hypothesis of the time-varying system were main sources of equivalent error.Then,online adjustment was put forward to overcome the error caused by the time-varying characteristics of the system.Parameters in the equivalent model were too many to adjust directly.And the additional fictitious impedances were introduced to overcome this d... |
