摘要
水电机组效率在线监测系统在水电厂运行中具有十分重要的意义,是水电站实现经济运行及机组状态检修的基础。介绍了利用AdLink NuDAM系列模块进行数据采集的方法,以及效率在线监测系统中参数监测、数据录入、处理、打印、报表、曲线绘制、参数设置等各项功能。介绍了NuDAM与微机通讯方式、数据保存以及利用最小二乘法绘制机组动力特性曲线的方法。运行实例表明该系统运行稳定可靠。
Online efficiency monitoring system of hydroelectric unit is very important for hydro power station operation, It is the basement of economical operation and condition based maintenance. This paper introduces the application of NuDAM models in ana log and switch data collcctioo in the efficiency monitoring system, and also the functions of the data monitoring, data inputting, processing, printing, reporting, curves drawing and parameters setting of the system. It presents the communication methods of Nu DAM models and computer, data storage and the method of least square in unit dynamic characteristic curves drawing. Practical operation shows that it is stable and reliable.
