Abstract

A system includes a secure data interface system. The secure data interface system includes a one-way communications interface configured to communicatively couple to a monitoring and protection system to receive data transmitted by the monitoring and protection system, and a processor configured to derive at least one measurement based on the data. The secure data interface system further includes a two-way communications interface configured to communicate the measurement to an external system, wherein the monitoring and protection system is configured to monitor operations of a machinery.

Claims

1. A system comprising:

a secure data interface system comprising;

a one-way communications interface configured to communicatively couple to a monitoring and protection system to receive data transmitted by the monitoring and protection system;

a processor configured to derive at least one measurement based on the data; and

a two-way communications interface configured to communicate the at least one measurement to an external system, wherein the monitoring and protection system is configured to monitor operations of a machinery.

2. The system of claim 1, wherein the processor is configured to emulate the monitoring and protection system to derive the at least one measurement.

3. The system of claim 1, wherein the at least one measurement comprises a keyphasor measurement, a vibration measurement, an axial position, a radial position, a casing velocity, a casing acceleration, a temperature, a differential expansion, an overspeed detection, a rotor wheel acceleration, an actuator position, a shaft eccentricity, rolling element bearing activity monitor data, a speed measurement, a clearance measurement, a pressure measurement, or a flow measurement.

4. The system of claim 1, wherein the secure data interface comprises a rack-mountable card configured to couple with a backplane included in a rack of the monitoring and protection system.

5. The system of claim 1, wherein the secure data interface comprises a standalone system communicatively coupled to the monitoring and protection system.

6. The system of claim 1, wherein the processor is configured to apply a configuration data to maintain a synchronization between the secure data interface system and the monitoring and protection system, and wherein the configuration data is applied manually, automatically, or a combination thereof, based on changes to the monitoring and protection system.

7. The system of claim 1, wherein the two-way communications interface is configured to use a plant data highway to communicatively couple to the external system, and wherein the external system comprises a human machine interface (HMI), a distributed control system (DCS), a decision support system (DSS), or a combination thereof.

8. A tangible non-transitory machine readable medium storing instructions configured to:

receive, via a one-way communications interface, data related to turbomachinery operations;

provide an emulated monitoring and protection system;

derive at least one measurement by providing the data as input to the emulated monitoring and protection system, wherein the at least one measurement comprises an output of the emulated monitoring and protection system; and

communicate the at least one measurement to an external system.

9. The tangible non-transitory machine readable medium of claim 8, wherein the data comprises a sensor data representative of the turbomachinery operations.

10. The tangible non-transitory machine readable medium of claim 8, wherein the at least one measurement comprises a keyphasor measurement, a vibration measurement, an axial position, a radial position, a casing velocity, a casing acceleration, a temperature, a differential expansion, an overspeed detection, a rotor wheel acceleration, an actuator position, a shaft eccentricity, rolling element bearing activity monitor data, a speed measurement, a clearance measurement, a pressure measurement, or a flow measurement.

11. The tangible non-transitory machine readable medium of claim 9, wherein the sensor data comprises a thermocouple data, a proximity sensor data, an eddy current sensor data, an ultrasonic sensor data, a velocity sensor data, a vibration sensor data, a pressure sensor data, a clearance sensor data, an accelerometer data, a gyroscope data, a chemical sensor data, an optical sensor data, or a combination thereof.

12. The tangible non-transitory machine readable medium of claim 8, comprising instructions configured to receive an indication of a change in a configuration of a monitoring and protection system, wherein the emulated monitoring and protection system emulates the monitoring and protection system.

13. The tangible non-transitory machine readable medium of claim 12, wherein the indication comprises a configuration version ID.

14. The tangible non-transitory machine readable medium of claim 12, wherein the indication is encoded as a voltage level, a frequency, a pulse stream, or a combination thereof.

15. The tangible non-transitory machine readable medium of claim 12, wherein the change in configuration comprises a parameter, a variable, a program, a firmware, or a combination thereof.

16. The tangible non-transitory machine readable medium of claim 12, comprising instructions configured to update the emulated monitoring and protection system based on the indication to maintain a synchronization with the monitoring and protection system.

17. The tangible non-transitory machine readable medium of claim 12, comprising instructions configured to alert a user after receiving the indication of the change.

19. The method of claim 17, comprising synchonizing a configuration data between the monitoring and protection system and the secure data interface system.

18. A method comprising:

monitoring operations of a machinery by using a monitoring and protection system;

operating using the monitoring and protection system to only transmit a first data via a one-way data flow;

operating using a secure data interface system to receive the first data via the one-way data flow;

processing the first data to derive a machinery measurement by emulating the monitoring and protection system if the first data comprises a raw sensor data; and

transmitting the machinery measurement to an external system via a two-way data flow.

20. The method of 17, comprising querying the secure data interface system for a second data by using the two-way data flow.
