摘要
依据大坝发电有限责任公司#1机组谐波测量的结果,分析研究了发电机中的三次谐波电压的变化规律,得出了升压变压器高压绕组的三次谐波零序电动势,是影响发电机定子接地保护三次谐波电压的主要因素的结论。
According to the result of Unit 1 harmonic measurement in Daba Electric Power Generation Co., Ltd., analyzes the changing rule of thrice harmonic voltage in the generator, draws the conclusion that the thrice harmonic zero-sequence electromotive force of high -voltage winding in step-up transformer is the main factor affecting thrice harmonic voltage of stator grounding protection in the generator.
