摘要： A system and method for monitoring the operating conditions of a steam turbine and developing an adaptive inspection interval includes access to a digital data storage archive containing information relating to use and operation of comparable steam turbines and plant/service events, one or more turbine operational condition sensors for monitoring steam quality in real time during operation of the steam turbine. A processor calculates a steam quality value based upon cation conductivity of the steam used to operate the steam turbine as measured by the sensors. The processor uses the calculated steam quality information either alone or together with other acquired operational and parametric data to determine an adapted inspection interval for the steam turbine. The processor produces an output which includes the determined adapted inspection interval and may additionally include updated maintenance and repair schedules. A method for adapting an inspection interval for a particular steam turbine at a particular plant involves considering a calculated steam quality of the steam provided to the turbine, considering any available corrosion diagnostics data obtained during any turbine stand-still lay-off times, considering any relevant turbine fleet information and historical plant/service event information, and evaluating these parameters and informations to determine an adapted maintenance interval for the steam turbine. The method includes calculating a steam quality value in accordance with a predetermined formula based on a real-time measured conductivity of the steam provided to the turbine during operation and generating a output specifying an inspection interval adapted to the particular steam turbine and plant of operation.

摘要： A system includes a controller including a memory storing instructions and a processor that executes the instructions. The instructions cause the controller to control a steam turbine system coupled to a power generation system to release steam during deceleration of a gas turbine. The instructions cause the controller to receive a first temperature of the gas turbine and a rotational speed of the gas turbine. The instructions cause the controller to calculate an exhaust flow rate of the power generation system based on at least the first input signal and the second input signal. The instructions cause the controller to control the power generation system to isolate a fuel source from the gas turbine at a portion of normal operating speed of the gas turbine sufficient to achieve a predetermined purging volume during coast down of air flow through the power generation system based on the exhaust flow rate.
