Abstract
A method for estimating an amount of damage sustained by a component operating in an energy system includes generating a transfer function that is dependent upon at least one operating condition of the component, receiving data from at least one sensor coupled to the component, wherein the data relates to the at least one operating condition of the component, inputting the received data into the transfer function to calculate at least one of a crack-initiation time and a crack propagation for the at least one critical region, and recording at least one of the crack-initiation time and the crack propagation on a memory storage device.
Claims20
A method for estimating an amount of damage sustained by a component operating in an energy system, the method comprising:
- generating a transfer function that is dependent upon at least one operating condition of the component;
- receiving data from at least one sensor coupled to the component, wherein the data relates to the at least one operating condition of the component;
- inputting the received data into the transfer function to calculate at least one of a crack-initiation time and a crack propagation for the at least one critical region;
- and
- recording at least one of the crack-initiation time and the crack propagation on a memory storage device.
A method of operating an energy system including a component that has at least one critical region which may develop a crack therein, said method comprising:
- developing a transfer function for the at least one critical region, wherein the transfer function is based upon at least one operating condition;
- receiving data from at least one sensor coupled to the component, wherein the data relates to the at least one operating condition;
- applying the data to the transfer function of the at least one critical region to calculate at least one of the crack-initiation time and the crack propagation for the at least one critical region;
- and
- determining at least one of an operating schedule and an operating parameter for the energy system based on at least one of the crack-initiation time and the crack propagation.
A method in accordance with claim 7 further comprising monitoring the operation of at least one globe valve and that includes a plurality of critical regions.
A control system for operating an energy system, said control system comprising:
- a component comprising a predetermined transfer function based on at least one operating condition of the energy system;
- at least one sensor coupled to said component for monitoring said at least one operating condition of said component;
- and
- a processor programmed to:
- receive data from said at least one sensor, said data relating to at least one operating condition of said component;
- apply said data to said transfer function to calculate at least one of a crack-initiation time and a crack propagation within said at least one critical region;
- and
- record at least one of said crack-initiation time and said crack propagation of at least one critical region on a memory storage device.
