Woodward 8200-1302 Digital Governor Turbine Control

The Woodward 8200 - 1302 is a 505D digital governor used for steam turbine control. Functional FeaturesControl Functions Automatic Startup: It has an automatic startup sequence function for both hot and cold starts, with a temperature input option.   It can automatically adjust the startup process according to different operating conditions. Critical Speed Avoidance: It can avoid critical speeds in three speed bands, preventing the steam turbine from operating near critical speeds, avoiding problems such as resonance, and ensuring the safe and stable operation of the equipment.Advanced Algorithms: It adopts intelligent/adaptive control algorithms, such as the Optitune adaptive PID technology, which can optimize the performance of the steam turbine.   There is also an acceleration PID that can limit overshoot and enable a stable and efficient startup of the power plant. Monitoring and Protection: It has a reverse rotation sensing and alarm function, as well as a vibration monitoring function (requires the 8928 - 7482 sensor kit).   It can monitor the operating status of the steam turbine in real - time, alarm in case of abnormal situations, and take protective measures.

Communication Functions

Multiple Communication Interfaces: It supports Ethernet communication and can be connected to the power plant's DCS system, service tools, and remote - view operator control panels.   It also has a Canopen actuator connection function for connecting Woodward variable - stroke actuators and the DSLC - II power management network, facilitating communication and collaborative work between devices. Human - Machine Interaction Functions Graphical Interface: It integrates a graphical front - panel HMI screen that supports multiple languages including Chinese.   The large screen is convenient for operation, viewing parameters and performance, and can display trends in real - time, facilitating on - site monitoring by operators and engineers.   Configurable Labels: Configurable label names can be set for easy identification of connections.   There is an internal "turbine simulator" for offline training and advanced testing before system changes.   Input/Output Functions Analog Input: There are 8 analog input channels, which are 4 - 20mA inputs with loop power supply and can be configured for any of the twenty - seven functions.   Speed Input: There are two redundant speed inputs that can accept inputs from magnetoelectric sensors, eddy - current probes, or proximity probes.   Contact Input: There are a total of 20 contact inputs.   The first four are defaulted for shutdown, increasing the speed setpoint, resetting, and decreasing the speed setpoint, and the rest can be configured as needed.   Control Output: There are two 4 - 20mA control outputs that can be used to control external devices.   Relay Output: There are eight type - C relay contact outputs that can achieve signal conversion and control.Performance Parameters Input Voltage: Low - voltage 18 - 36VDC isolated.   Electromagnetic Compatibility Immunity: EN 61000 - 6 - 2.   Housing Type: IACS UR E10 (merchant ship), with ATEX, IP - 54, and pollution degree 3 characteristics.   Operating Temperature: - 22°F - 158°F (approximately - 30°C - 70°C).   Storage Temperature: - 22°F - 158°F (approximately - 30°C - 70°C).   Screen Size: 8.4 - inch LCD screen.   Application Scenarios It is mainly used for the control of industrial steam turbines.   For example, in power plants powered by steam turbines or gas turbines, it can precisely control the operation of the steam turbine, ensuring the stable and efficient power output of the generator set.   In the petrochemical industry, it is used in the steam turbine control systems of large compressors, pumps, and other equipment to achieve precise control of the steam turbine and ensure the continuity and safety of the production process.

Advantages of the Woodward 505D Digital Governor Precise Control Performance: It adopts advanced intelligent/adaptive control algorithms, such as the Optitune adaptive PID technology, which can automatically optimize control parameters according to the actual operating conditions of the steam turbine, achieving precise adjustment of the steam turbine's speed and power.   The acceleration PID function can effectively limit overshoot, enabling the steam turbine to operate stably during startup, load changes, etc., greatly improving the control accuracy and stability, and thus enhancing the overall performance and efficiency of the equipment.   Powerful Protection Function: It has a reverse rotation detection and alarm function, which can promptly detect the reverse rotation of the steam turbine and issue an alarm, preventing the equipment from being damaged due to reverse rotation.   The vibration monitoring function (with a specific sensor kit) can monitor the vibration status of the steam turbine in real - time.   When the vibration is abnormal, it can take timely measur
