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.
