In one embodiment, a system is provided. The system includes a combustor configured to combust a fuel, and a three-way valve fluidly coupled the combustor and disposed upstream of the combustor. The system also includes a fuel circuit comprising a fuel supply, wherein the fuel circuit is disposed upstream of the three-way valve and is configured to provide the fuel to the three-way valve. The system additionally includes a fuel conduit section fluidly coupling the fuel circuit to the combustor. The system further includes an inert fluid supply configured to provide an inert fluid to the three-way valve and a compressor discharge (CPD) fluid source configured to provide a purge fluid to the three-way valve. The three-way valve is configured to purge the fuel from a first portion of the fuel conduit section by using the purge fluid.

A monitoring system for use with a turbine engine is described herein. The turbine engine includes a compressor and at least one compressor bleed valve coupled to the compressor. The monitoring system includes at least one sensor that is for sensing an operational parameter of the compressor bleed valve, and a controller that is coupled to the sensor and the compressor bleed valve. The controller is configured to determine an operating mode of the turbine engine and receive a monitoring signal indicative of the sensed operational parameter. The controller is also configured to calculate at least one operational value of the compressor bleed valve based at least in part on the sensed operational parameter. The controller is further configured to determine a condition of the turbine engine based at least in part on the calculated compressor bleed valve operational value.

System and method of monitoring turbine engines

Systems and methods for prediction of gas turbine trips due to component failures such as thermocouple failures. Exemplary embodiments include prediction of gas turbine trips due to component failures, including collecting raw gas turbine operational data and using the raw gas turbine operational data to generate a prognostic indicator for the prediction of a turbine trip due to the failed thermocouples.

A system and method are provided for monitoring the operation of a plurality of turbines in respective operating locations. The method includes inputting operation data from each of the turbines and processing the operation data to generate secondary operation data. Further, the method also includes generating at least one report based on the secondary operation data.

System and method for processing operation data obtained from turbine operations

A machine protection system and method for rotating equipment introduces new alarming features and makes use of full proximity probe sensor information, including amplitude and phase. Baseline vibration amplitude and phase data is estimated and tracked according to operating modes of the rotating equipment. Baseline vibration and phase data can be determined using a rolling average and variance and stored in a unit circle or tracked using short term average and long term average baselines. The sensed vibration amplitude and phase is compared with the baseline vibration amplitude and phase data. Operation of the rotating equipment can be controlled based on the vibration amplitude and phase.
