60Hz汽轮发电机励磁电流分析与计算

Calculation and Analysis of Field Current for 60 Hz Turbo Generator

利用电磁场有限元方法对660 MW 60 Hz发电机进行空载特性、短路特性计算分析,得到空载磁密、波形、空载特性和短路特性曲线,以此进行额定励磁电流计算。与传统磁路计算结果及试验值比较,计算结果比较合理。

This paper provides calculations and analyses of no-load eharac, teristie and short-circuit characteristic of 660 MW turbo generator （60Hz） by using electromagnetic field finite element method, arriving at results of no-load flux density, waveform, no-load and short-circuit characteristic curves. The rated excitation current is further calculated based on the said results with values which are more reasonable as compared with the conventional magnetic calculations and experimental method.
