摘要:

结合电厂巡点检数据处理的发展现状和某热电厂的实际情况,以发电设备状态参数为研究对象,建立了基于灰色理论的数学模型,进行了状态参数的预测和评价;使用“改进灰色模型”通过引入m点均算因子,对具有波动性的原始发电设备运行参数序列进行m点均值处理,使原始数据满足灰色模型光滑性的要求。结果表明,使用改进的灰色模型能更加准确地预测和评价该电厂发电设备的运行状态,最终实现了对点检数据处理分析的目的。

Abstract:

Combining the development status of power plants spot check and actual situation of a thermal power plant, taking the state parameters of generation equipment as research object, a mathematical model based on Gray Theory is established, which can be used for state parameters prediction and evaluation. By introducing mpoint factor, the improved Gray Model can make m point average process on volatile operating parameters sequences of generation equipment, which makes the original data meet the the smoothness requirements of Grey Model. The results show that the improved Gray Model can predict and evaluate the operation status of power plants more accurately and achieve the purpose of processing of spot check data.
