大数据时代基于全工况的机组稳定性分析

Stability Analysis of Hydraulic Generator Set based on All Working Conditions in the Era of Big Data

本文对比了几种对机组稳定性数据解析的方法,针对各方法的优劣,创造性地提出用Matlab对水布垭积累的大数据进行挖掘、整理、分析,完善了对数据的可视化,以寻找运行规律。同时,讨论了机组稳定性问题的根源,就机组的调度控制提出建设性的意见,从而有力提升运行管理水平。

This paper compares several methods for analyzing the stability of generating units. Aiming at the strengths and weaknesses of various analytical methods,it creatively puts forward the use of Matlab classification mining,sorting,statistical analysis of the big data which accumulated of shuibuya hydropower station in nearly ten years. Then it improves the visual operation of the data to find the running law. At the same time,this paper discusses the root causes of the stability of the unit,puts forward the constructive suggestion of the unit dispatch control,effectively improves the operation management level of power plant.
