Abstract

The original dynamic model of the synchronous round-rotor generator also known as synchronous turbo-generator (STG) in stand-alone mode of operation is developed and presented in the paper. The model is based on Winding Function (WF) theory and as such it is derived in the natural frame of reference. Depending on the presence or absence of a damper winding on the rotor two independent mathematical models are derived. The presented model provides an accurate description of the real spatial distribution of all windings in the machine, including the short-circuited damper cage winding. Currents in all windings of the machine over time, including all bars of the damper winding, are output from the model. Moreover, the time required to run the model on a computer of average performance is measured in minutes, which is unimaginably fast compared to similar models based on the Finite Element Method (FEM). On the other hand, the results obtained with a completely different and independent time stepping FEM based model largely confirm the validity of the results obtained with the proposed model.

带阻尼器绕组的独立同步涡轮发电机绕组功能模型

本文开发并介绍了同步圆转子发电机（又称同步涡轮发电机（STG））在独立运行模式下的原始动态模型。该模型基于绕组函数（WF）理论，因此是在自然参照系中推导出来的。根据转子上是否存在阻尼绕组，可推导出两个独立的数学模型。该模型准确描述了机器中所有绕组的实际空间分布，包括短路阻尼笼绕组。该模型可输出机器所有绕组的电流随时间变化的情况，包括阻尼器绕组的所有条形绕组。此外，在性能一般的计算机上运行该模型所需的时间以分钟计，与基于有限元法（FEM）的类似模型相比，速度快得难以想象。另一方面，使用基于有限元法的完全不同且独立的时间步进模型所获得的结果在很大程度上证实了使用所提议的模型所获得结果的有效性。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
