Control device and control method
A control device includes an interface module configured to supply electric power to a field device installed in a plant, an application executer configured to output a reset signal for resetting the field device, and a converter configured to convert the reset signal, which has been output from the application executer, into a format which is suitable for the interface module.
Motor control system, motor controller, and method for setting safety function
A motor control system includes a motor, and motor control circuitry that controls driving electric power for the motor based on a driving state quantity of the motor, and upon input of a safety request signal from outside the motor control circuitry, monitors a relationship between a driving state quantity and an operation monitor pattern selected from multiple kinds of operation monitor patterns using multiple simultaneously functioning safety function software modules.
Emergency shutdown system for dynamic and high integrity operations
Provided in some embodiments are systems and methods for emergency shutdown (ESD) systems. Embodiments provide for receiving, from a central logic solver (CLS) of an emergency shutdown (ESD) system for a plant via a first communication channel, a command indicative of a first state for an ESD valve, in response to receiving the command, controlling the ESD valve to operate in the first state, obtaining, from a central status monitor (CSM) of the ESD system via a second communication channel, current status information for the plant, determining a second state for the ESD valve based at least in part on the current status information obtained from the CSM, and controlling the ESD valve to operate in the second state.
Protective functions for parallel generators
A generator system may include two or more generators electrically connected through a generator bus. A controller receives operation data from a first generator. The operation data may describe a power flow from a second generator to the first generator. From the operation data, either a loss of speed control or a loss of voltage control may be identified at the second generator. The controller may generate a command for the second generator based on the loss of speed control or the loss of voltage control.
MOTOR CONTROL SYSTEM, MOTOR CONTROLLER, AND METHOD FOR SETTING SAFETY FUNCTION
A motor control system includes a motor, and motor control circuitry that controls driving electric power for the motor based on a driving state quantity of the motor, and upon input of a safety request signal from outside the motor control circuitry, monitors a relationship between a driving state quantity and an operation monitor pattern selected from multiple kinds of operation monitor patterns using multiple simultaneously functioning safety function software modules.
System and method for upgrading multivendor wind turbines
The present disclosure is directed to a system and method for controlling and/or upgrading aftermarket multivendor wind turbines. The system includes a turbine controller configured to control operations of the wind turbine, a safety device configured to provide a signal indicative of a health status of the safety device, and a secondary controller inserted between the safety device and the turbine controller. The secondary controller is configured to receive the signal from the safety device over a communication interface. As such, if the signal indicates a normal health status, the secondary controller is configured to send the signal to the turbine controller, i.e. maintain normal operation. Alternatively, if the signal indicates a poor health status, the secondary controller is configured to adjust the signal based at least in part on a signal bias to an adjusted signal and to provide the adjusted signal to the turbine controller.
SYSTEM AND METHOD FOR PLANT CONTROL BASED ON FLUID QUALITY
A distributed control system receives analysis data. The analysis data includes quality attributes of fluid samples and an indication of a plant location corresponding to the fluid samples. The system identifies one or more anomalies of fluid based upon the quality attributes of the plurality of fluid samples and attributes the one or more anomalies to one or more particular areas. The system triggers an alert, trigger control, or both, based at least in part upon the identified one or more anomalies and the attributed one or more particular areas.
