自适应灰关联算法的动力装置故障诊断

Fault Diagnosis for Power Plant Based on Adaptive Gray Relation Algorithm

动力装置在长期运行后,其部件性能会逐渐衰退,容易导致各种故障发生。因此,对装置进行一定的气路数据测量,进而对装置进行诊断、预测具有重要意义。提出一种自适应灰色关联算法的动力装置故障诊断算法,通过对故障数据的关联计算处理,实现了动力装置故障模式的诊断。

Components in a power plant may degrade during operation,leading to serious faults.It is therefore essential to monitor gas-path measurement in a power plant,and carry out fault diagnosis for its components.For this purpose,a fault diagnostic method for power plant based on adaptive gray relation algorithm is proposed.By correlating calculation of the gas-path measurement,accurate recognition of fault patterns can be achieved.
