摘 要:水轮发电机轴线分析对水电厂水轮发电机组运行具有重要意义,本文分析了机组日常检修轴线测量存在的弊端以及机组运行过程中轴线监测的重要性,提出一种基于各摆度波形动态研究机组轴线的方法。根据机组实际运行动态,360°采集各方位的摆度值及其相位,采用数学向量合成分析的方法,借助计算机实时计算分析,进行机组轴线动态监测并判断其是否存在曲折以及曲折的方位,从而指导机组检修时的轴线调整。通过对机组实际摆度的采集数据进行举例计算分析,验证了本文所提方法的有效性,对水轮发电机组运行监测以及状态分析具有良好的指导意义。The axis analysis of hydro-generator is of great significance to the operation of hydro-generator unit in hydropower plant.This paper analyzes the disadvantages of the axis measurement in the daily maintenance of the unit and the importance of axis monitoring during the operation of the unit,and puts forward a method for dynamically studying the axis of the unit based on each swing waveform.According to the actual operation dynamics of the unit,the swing value and phase of each azimuth are collected at 360°.Using the method of mathematical vector synthesis analysis,with the help of computer real-time calculation and analysis,the dynamic monitoring of the unit axis is carried out to judge whether there are twists and turns,as well as the orientation of the twists and turns,so as to guide the axis adjustment during the maintenance of the unit.Through the calculation and analysis of the actual swing data of the unit,the effectiveness of the method proposed in this paper is verified,which has a good guiding significance for the operation monitoring and condition analysis of the hydro-generator unit.
