3. Brand History
Woodward, Inc., founded in 1870 and headquartered in Fort Collins, Colorado, USA, is a global leader in energy control systems. The company has a long history of innovation in turbine control, engine management,
and power generation systems.
Woodward products are widely recognized for their reliability and precision in demanding industrial and power generation applications.
4. Applications in Industrial Automation
The 9905-763 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
3. Control accuracy
Control accuracy refers to the motor operation accuracy that the driver can achieve, including speed control accuracy and position
control accuracy. High precision drivers can ensure the stability and repeatability of motor operation, which is particularly important for precision control applications.
4. Response time
Response time refers to the speed at which the driver responds to control signals, which directly affects the dynamic performance
of the system. Fast response time can improve the system”s response speed and stability.
5. Protection function
Drivers usually have multiple protection functions, such as overload protection, overheating protection, short circuit protection, etc.,
which can protect motors and drivers from damage.
Control method of the driver
1. Voltage control (V/f control)
Voltage control is a fundamental control method that adjusts the speed of a motor by changing its supply voltage and frequency.
This control method is simple and easy to implement, but the control accuracy and dynamic response are relatively poor.
