WOODWARD 9907-167 Steam Turbine digital governor
WOODWARD 9907-167 Steam Turbine digital governor
INTRODUCTION
WOODWARD 9907-167 Steam turbine digital governor by collecting the speed signal of the steam turbine, according to the preset control logic and parameters, automatically adjust the gas intake, exhaust and other parameters of the steam turbine, in order to achieve the stable operation of the steam turbine and the accurate control of the output power. It has the characteristics of high precision, high stability and fast response, and can adapt to different types of steam turbines and operating environments.
WOODWARD 9907-167 The use of the Woodward Turbine digital governor consists of the following steps:
Installation and connection: Install the governor to the control cabinet or operating platform near the steam turbine, and connect the sensor and actuator according to the instructions to ensure correct signal transmission and action execution.
Power supply and communication: Provide the required power supply for the governor, and use the appropriate communication interface to connect the governor to the upper computer or monitoring system. Ensure correct configuration and parameter Settings of communication interfaces.
Parameter setting: According to the turbine model, operation requirements and control system requirements, set the control parameters of the governor, such as target speed, start/stop speed, acceleration/deceleration, etc.
Control program writing: The use of supported programming languages (such as C++, C#, etc.) to write control programs, according to the actual control logic and algorithm to achieve the control and operation of the governor. Ensure the correctness and stability of the control program.
Program download and debugging: the written control program is downloaded to the governor, and debugging and testing are carried out to ensure that the governor can operate normally in accordance with the preset control logic and parameters, and can correctly respond to the state changes and operational requirements of the turbine.
Operation and maintenance: Start the steam turbine and control system and run the governor. During operation, it is necessary to pay close attention to the running state and parameter changes of the governor, and adjust and control the speed and output power of the turbine in time. At the same time, regular maintenance and maintenance is also an important measure to ensure the normal operation and service life of the governor.
Technical features
High immunity: Highly immune to electrical disturbances on the power supply and able to maintain stable performance in complex electromagnetic environments. This feature enables it to operate reliably in a variety of industrial environments.
Highly efficient and durable design: It adopts a rugged design and uses high-quality components to operate reliably in harsh environments. Its wide operating temperature range of -40°C to +85°C and anti-vibration, dustproof and waterproof ratings up to IP67 ensure that the device can work properly under various extreme conditions.
Precise control: Adopting advanced PID control algorithm, it can achieve precise control of rotational speed with an accuracy as high as ±0.25%. This high-precision control can meet the needs of a variety of complex working conditions.
Easy to use: Providing an intuitive user interface, users can easily view and set parameters through the LCD display on the front panel. It also supports a variety of communication interfaces (e.g. RS-485, etc.), which makes it easy for users to integrate with other systems.
Multiple Output Voltage Options: In addition to the standard 24V power supply, other output voltage options are available to suit different working conditions.
Fields of application
WOODWARD 9907-167 is widely used in the following areas:
Cogeneration: In cogeneration systems, it is used to control the rotational speed and output power of the steam turbine to meet the demand for power generation and heat supply.
Power plants: In power plants, as the core control component of the steam turbine, to ensure the stable operation of the generating unit and efficient power generation.
