摘要
目前国内外立式水轮发电机组轴线调整均采用等相位定点盘车、人工架表测量、人工计算调整的方式,不仅盘车周期长、人工测量和计算工作量大,而且因定点盘车测点数少、调整方案主观性强,导致计算和调整精度不高,工作效率普遍较低。本文提出了一种适用于立式水轮发电机组的轴线智能调整系统,采用连续盘车轴线调整工艺,实现了盘车数据的自动采集、无线通信、自动计算分析,并自动给出轴线调整方案。该系统已在葛洲坝电站成功应用,可大幅提升机组轴线调整工艺的智能化水平。
To date,the axis adjustment of a vertical hydro-generator unit in China and abroad has adopted the method of constant-phase fixed-point turning,manual table measurement,and manual calculation adjustment.Not only does this require a long turning cycle and a heavy workload of manual measurement and calculation,but its work efficiency and the accuracy of calculation and adjustment are relatively low due to the lack of sufficient measurement points and strong subjectivity in adjustment schemes.This paper develops an intelligent axis adjustment system for vertical hydro-generator units.By using the continuous turning axis adjustment process,we have achieved automatic data collection,wireless communication,and automatic calculation and analysis of the turning data.This system can generate axis adjustment schemes automatically.Its successful application at the Gezhouba hydropower station proves that it can greatly raise the intelligent level of axis adjustment process.
