IV.Operation and maintenance

Installation and connection:Install the speed governor to the control cabinet or operating platform near the steam turbine,and connect the sensors and actuators according to the instructions to ensure correct signal transmission and action execution.

Power supply and communication:Provide the required power to the speed governor,and use the appropriate communication interface to connect the speed governor to the host computer or monitoring system.Ensure the correct configuration and parameter setting of the communication interface.

Parameter setting:Set the control parameters of the speed governor,such as target speed,start and stop speed,acceleration and deceleration,etc.,according to the turbine model,operation requirements and control system requirements.

Control program writing:Use supported programming languages(such as C++,C#,etc.)to write the control program,and realize the control and operation of the speed governor according to the actual control logic and algorithm.Ensure the correctness and stability of the control program.

Program download and debugging:Download the written control program to the speed governor,and debug and test it to ensure that the speed governor can operate normally according to the preset control logic and parameters,and can correctly respond to the state changes and operation requirements of the turbine.

Operation and maintenance:Start the turbine and control system,and run the speed governor.During the operation,pay close attention to the operating status and parameter changes of the speed governor,and adjust and control the speed and output power of the turbine in time.At the same time,regular maintenance and care are also important measures to ensure the normal operation and service life of the speed governor.
