2.Application areas
Cogeneration:
In the cogeneration system,it is used to control the speed and output power of the steam turbine to meet the power generation and heating needs.
Power plant:
In traditional thermal power plants or nuclear power plants,as the core control component of the steam turbine,it ensures the stable operation and efficient power generation of the generator set.
Industrial field:
In industrial fields such as chemical,metallurgical,and papermaking,it is used to control the speed and output power of various rotating machinery.Especially in occasions where high-power drive is required,such as steel,petrochemical,cement and other industries.
Ship power system:
In large ships,it is used to control the speed of the ship’s main propulsion turbine engine to achieve the forward and stop of the ship,ensuring the safety and performance of the ship’s navigation.
Other applications:
It can also be used in generator control,pump control,fan control,compressor control,and conveyor control.

4.Use and maintenance
Installation and connection:
Install the speed governor to the control cabinet or operating platform near the 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 connect the speed governor to the host computer or monitoring system using the appropriate communication interface.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 and debugging:
Use supported programming languages(such as C++,C#,etc.)to write control programs,and implement control and operation of the speed governor according to actual control logic and algorithms.Ensure the correctness and stability of the control program.
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.
Operation and maintenance:
Start the turbine and control system and run the speed governor.During 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.
Regular maintenance and care are also important measures to ensure the normal operation and service life of the speed governor.
In summary,WOODWARD 9907-167 digital electronic speed governor has been widely used in many fields with its high-precision control,high stability and reliability,high anti-interference,easy to use and maintain,and multiple output voltage options.
