Publication number: 20240102388Abstract: A system for controlling a turbine valve is provided. The system includes a hydraulic pilot valve section being moveable in a first direction and a second direction; a main hydraulic valve section being moveable in a first direction to close the turbine valve and a second direction to open the turbine valve; a position demand indicating a desired position of the turbine valve; a first feedback indicating an actual position of the hydraulic pilot valve section; and aa second feedback indicating an actual position of the main hydraulic valve section. The system also includes a pilot valve error; a main valve error; a turbine valve error; and a pilot valve adjustment moving the hydraulic pilot valve section in response to the turbine valve error. The turbine valve error is repeatedly determined and the pilot valve adjustment repeatedly moves the hydraulic pilot valve section to minimize the turbine valve error.Type: ApplicationFiled: October 26, 2023Publication date: March 28, 2024Applicant: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller, Kevin Dowdell, Mark Wieland, Alan Majors

Patent number: 11898449Abstract: A turbine control system is provided for decreasing the response time between readings of the speed of the turbine and changing a valve position in response thereto. The speed control system includes a speed probe that detects the speed of the turbine and a turbine valve that controls the flow of fluid or gas from or to the turbine. A controller receives a speed signal from the speed probe and sends valve position commands to the turbine valve. The controller also sends support functions to the turbine valve. The controller sends the valve position commands at a faster rate than the support functions.Type: GrantFiled: November 9, 2020Date of Patent: February 13, 2024Assignee: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller

Patent number: 11814964Abstract: A control system is provided for a turbine valve. The turbine valve has a first coil and a second coil to control or sense movement of a mechanical valve positioner. Two valve positioners are provided with each valve positioner having two drive circuits to drive the first and second coils. Switches are provided such that only one drive circuit is connected to each coil at a time. The control system may also include a hydraulic pilot valve section and a main hydraulic valve section. Feedbacks are used to determine a pilot valve error and a main valve error which are combined to determine a turbine valve error. The turbine valve error is repeatedly determined to minimize the error.Type: GrantFiled: November 9, 2020Date of Patent: November 14, 2023Assignee: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller, Kevin Dowdell, Mark Wieland, Alan Majors

Patent number: 11773721Abstract: A turbine speed probe diagnostic system is provided. The turbine includes a speed probe and a speed reading circuit. A speed lead connects the speed probe and speed reading circuit together to transmit speed signals from the speed probe to the speed reading circuit. A speed probe diagnostic circuit is also provided for connection to the speed lead. An isolation switch is provided to isolate the speed probe diagnostic circuit during normal operation when the speed reading circuit is receiving speed signals from the speed probe. When no speed signals are being received, the isolation switch closes and the speed probe diagnostic circuit performs a test on the speed probe or speed lead.Type: GrantFiled: November 9, 2020Date of Patent: October 3, 2023Assignee: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller, Kevin Dowdell, Mark Wieland, Alan Majors

Patent number: 11486251Abstract: A speed control system and a power load balance detector for a turbine is provided. The speed control system includes a speed wheel with a plurality of teeth. A timer stores a time stamp when each of the teeth passes by a speed probe. A first speed estimate is determined for overspeed protection, and a second speed estimate is determined for operational speed control. The power load balance detector trips or shuts down the turbine when an unbalance is above a first threshold and the speed of the turbine is above a second threshold.Type: GrantFiled: November 9, 2020Date of Patent: November 1, 2022Assignee: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller, Kevin Dowdell, Mark Wieland, Alan Majors, Xudong Yang

Patent number: 11225867Abstract: A breaker between two electrical circuits is provided that is closed when electrical properties in both of the electrical circuits are matching. Two check circuits are provided for comparing electrical properties of the two electrical circuits. Each of the check circuits sets a corresponding authorization to close the breaker. The breaker is only closed if both check circuits set an authorization to close the circuit.Type: GrantFiled: November 9, 2020Date of Patent: January 18, 2022Assignee: ABB Schweiz AGInventors: Camilo Lopez, Mark Foltz, Steve Miller, Kevin Dowdell, Mark Wieland, Alan Majors
