The revival of the old synchronous condenser (SC) technology is presently occurring. Hence, this study is proposed on the electromagnetic design and evaluation of turbo wound-field flux switching machines (WF-FSMs) for SC operation, for the first time. Unlike classical wound-field rotating machines, WF-FSMs do not need brushless exciters while possessing a robust topology. A design process based on the frozen permeability technique in static 2-D finite element analysis script-based package, which enhances both iterative and analytic adjudications, is proposed to accurately predict the SC operation. To attain the specific design requirements (~300 MVAR, 16 kV), a global-optimized model (GOM) of the SC machine is obtained through a stochastic optimization process involving multiple objectives. Based on the GOM, simple torque ripple minimization techniques are implemented, from which a final benchmark design is selected. The proposed SC analytical design procedure is then tested and the expected V-curves clearly obtained. The whole design approach is further verified by experimenting on a small-scale prototype, which when synchronized to the grid, confirms the novelty and feasibility of the proposed SC design and operation.

基于绕场磁通切换机设计的透平同步调相机电磁性能预测


旧的同步调相机（SC）技术目前正在复兴。因此，本研究首次提出用于 SC 运行的涡轮绕线磁通开关机 (WF-FSM) 的电磁设计和评估。与传统的绕线磁场旋转电机不同，WF-FSM 不需要无刷励磁机，同时拥有稳健的拓扑结构。提出了一种基于静态二维有限元分析脚本包中的冻结渗透率技术的设计过程，该过程增强了迭代和分析裁决，以准确预测 SC 操作。为了满足特定的设计要求（~300 MVAR，16 kV），通过涉及多个目标的随机优化过程获得 SC 机器的全局优化模型（GOM）。基于 GOM，实施了简单的扭矩纹波最小化技术，并从中选择了最终的基准设计。然后测试所提出的 SC 分析设计程序，并清楚地获得预期的 V 曲线。通过在小型原型上进行实验，进一步验证了整个设计方法，当与电网同步时，证实了所提出的 SC 设计和运行的新颖性和可行性。
