流体网络在线性能评估与故障诊断方法

摘要

在流体网络机理建模的基础上，研究了各种性能退化因素对流体网络特性的影响，通过对网络当前特征参数与理想状态的偏差分析，给出了量化的流体网络性能评价指标，然后以该指标为依据，结合网络的拓扑结构和动态数据，实现了在线性能评估、故障诊断和故障定位。将该方法应用于实际工程案例，并通过仿真结果和实际情况的对比，证明了该方法的实用性和诊断评估结果的准确性。%Based on the fluid network modeling mechanism,the influences of various performance deg-radation factors on the characteristics of the fluid network are studied.Through the variance analysis of current network characteristic parameters and ideal state,the quantitative indexes of performance evaluation of fluid network are given based on which it is possible to carry out an online performance evaluation,fault diagnosis and location in combination with the network topology and dynamic data. The comparison of simulation results and practical situations of applying the method to engineering proves the method to be feasible and the evaluation result to be correct.
