摘要:
A turbine and method for determining turbine maintenance. The method for determining hot gas path turbine maintenance comprises recording a number of part load starts (79), base load starts (89), fast starts (141), full speed no load trips (231), and load trips (237); forming a weighted equivalent starts as a weighted summation of part load starts, base load starts, fast starts, full speed no load trips, and load trips; comparing the weighted equivalent starts to a predetermined threshold; and initiating the maintenance procedure. The method for determining rotor parts turbine maintenance comprises recording the number of fast starts, normal starts (143), and elapsed time starts (135) from shutdown to restart; forming a weighted equivalent starts as a weighted combination of fast starts, normal starts, and elapsed time starts from shutdown to restart; comparing the weighted equivalent starts to a predetermined threshold; and if a weighted equivalent starts exceeds the predetermined threshold, initiating the maintenance procedure.
