Some models also offer sulfur resistant conformal coating options to enhance the product’s corrosion resistance in corrosive gas environments containing sulfur, ensuring long-term reliable operation in harsh industrial environments.
Working principle
The operation of the WOODWARD 5009XT steam turbine controller is based on the closed-loop control principle. Through real-time monitoring and feedback of the operating parameters of the steam turbine, the control signal is continuously adjusted to achieve precise control of the steam turbine. The specific work process is as follows:
Parameter monitoring: The controller collects real-time operating parameters of the steam turbine through various sensors connected to the steam turbine system, such as speed sensors, temperature sensors, pressure sensors, vibration sensors, etc. These sensors convert physical quantities into electrical signals and transmit them to the input module of the controller.
Signal processing and comparison: The microprocessor of the controller processes and analyzes the input sensor signals, compares the collected actual operating parameters with the user’s preset target values, and calculates the deviation between the two. For example, in speed control, the actual speed is compared with the preset speed target value to obtain the speed deviation value.
Control algorithm calculation: Based on the calculated deviation value, the controller uses an internal preset control algorithm, such as PID control algorithm, to perform calculation processing. The PID algorithm calculates the corresponding control quantity based on the proportional, integral, and derivative parameters of the deviation, in order to determine the amplitude and direction of the adjustment required for the steam valve opening. For example, if the actual speed is lower than the target speed, the PID algorithm will calculate a control signal to increase the opening of the steam valve to increase the steam flow into the turbine, thereby increasing the speed; On the contrary, if the actual speed is higher than the target speed, calculate the signal to reduce the valve opening.
Control signal output: The control quantity obtained through control algorithm calculation is converted into corresponding electrical or hydraulic signals (depending on the type of actuator) through the output module of the controller, and transmitted to the actuator of the steam valve. The actuator adjusts the opening of the steam valve based on the received control signal, thereby changing the steam flow rate and pressure entering the steam turbine.
Feedback and adjustment of operating status: With the change of steam valve opening, the operating status of the steam turbine changes, and its operating parameters also change accordingly. These new operating parameters are once again fed back to the controller through sensors. The controller repeats the process of monitoring, comparing, calculating, and outputting, continuously adjusting the control signal to keep the operating parameters of the steam turbine within the preset target range, achieving stable and precise control of the steam turbine. Throughout the entire working process, the controller will also monitor other status information of the system in real time, such as the start/stop status of the equipment, the fault status of each component, etc., and make corresponding adjustments to the control strategy based on this information to ensure the safe and reliable operation of the system.
Precautions
Installation environment requirements: When installing the 5009XT controller, the appropriate installation environment should be strictly selected according to the requirements of the product manual. Avoid installation in places with high temperature, high humidity, strong electromagnetic interference, corrosive gases or dust to ensure the normal operation and service life of the controller. For example, when installing in a chemical production workshop, if there is a large amount of corrosive gas present, a model with anti-corrosion coating should be selected, and effective protective measures should be taken, such as installing in a sealed control cabinet. At the same time, it is necessary to ensure that the installation location has good ventilation and heat dissipation conditions to prevent the controller from being damaged due to overheating. For the model of front panel installation, attention should be paid to the requirements of protection level to avoid water splashing or dust entering the interior of the equipment.
Power connection and stability: Correctly connecting the power supply is the key to ensuring the normal operation of the controller. Be sure to connect according to the prescribed power specifications and wiring methods to ensure the stability and reliability of the power supply. In places with significant power fluctuations, it is recommended to install a voltage regulator or uninterruptible power supply (UPS) to prevent damage to the controller caused by abnormal power supply. At the same time, it is necessary to regularly check the connection of the power line to ensure that there are no loose or short circuits. In some remote areas or industrial sites with unstable power supply, using UPS can effectively avoid equipment failures and data loss caused by sudden power outages, ensuring the safe shutdown of steam turbine systems.
Matching and debugging of sensors and actuators: The 5009XT controller needs to be used in conjunction with various sensors and actuators, so in the selection and installation process, it is necessary to ensure the compatibility and matching of sensors and actuators with the controller. Different types of sensors and actuators have different technical parameters and working characteristics, such as range, accuracy, response time, etc., and should be selected reasonably according to actual application requirements and controller requirements. After installation, comprehensive debugging work should be carried out to ensure that the sensor can accurately collect the operating parameters of the steam turbine and transmit the signal correctly to the controller. At the same time, the actuator can accurately adjust the opening of the steam valve according to the control signal sent by the controller. During the debugging process, it is necessary to carefully check whether the installation position of the sensor is correct, whether the wiring is firm, and whether the action of the actuator is flexible and smooth. If there are any problems, they should be adjusted and repaired in a timely manner.
Parameter setting and optimization: When using the 5009XT controller, users should set various control parameters reasonably according to the actual operating conditions of the steam turbine and production process requirements. Improper parameter settings may lead to unstable device operation, decreased control accuracy, and even potential safety hazards. Before setting parameters, it is necessary to fully understand the performance characteristics, working conditions, and control requirements of the steam turbine, and refer to the product manual and relevant technical materials for setting. During the operation of the equipment, parameters can be optimized and adjusted according to the actual operating effect to achieve the best control effect. For example, when the load of a steam turbine varies greatly, it may be necessary to adjust the PID control parameters appropriately to improve the system’s response speed and stability. At the same time, it is important to keep records of parameter settings so that they can be quickly restored to the correct settings during equipment maintenance or controller replacement.
Regular maintenance and upkeep: To ensure the long-term reliable operation of the 5009XT controller, regular maintenance and upkeep work is required. Regularly check the appearance of the controller for damage or deformation, whether the interfaces are loose, and whether there is dust accumulation inside. For controllers with fan cooling, it is necessary to regularly clean the fan and cooling channels to ensure good cooling effect. Regularly upgrade the software of the controller to obtain the latest features and performance optimizations, while fixing possible software vulnerabilities. In addition, comprehensive inspections and maintenance of the steam turbine system, including sensors, actuators, steam pipelines, and other components, should be conducted regularly to ensure the normal operation of the entire system. Equipment operating in harsh environments, such as mining, metallurgy, and other industries, may require a shortened maintenance cycle to ensure its reliability.

Core functions
（1） Speed and frequency control
Accurate speed regulation: Using advanced control algorithms, the speed of the steam turbine can be precisely adjusted according to the set value, with a control accuracy of ± 0.1% of the rated speed, ensuring that the steam turbine can operate stably under different load conditions, providing stable power output for applications such as power generation and mechanical drive. For example, in power generation scenarios, stable rotational speed is a key factor in ensuring power quality. WOODWARD 505 can effectively maintain rotational speed stability, reduce frequency fluctuations, and improve power generation efficiency and power quality.
Frequency following function: It can automatically adjust the speed of the steam turbine based on the grid frequency or other external frequency signals, achieving synchronous operation with the grid or other equipment, enhancing the adaptability and compatibility of the steam turbine in complex power systems. In a power plant with multiple units operating in parallel, each unit needs to work together through frequency synchronization. The frequency following function of 505 can ensure that each turbine can accurately match the grid frequency, ensuring the stable operation of the power system.
（2） Pressure control
Multiple pressure control modes: supports controlling or limiting the pressure of multiple parts of the turbine, such as intake, exhaust, and extraction. For example, at the inlet of a steam turbine, the inlet pressure can be precisely controlled according to actual needs to ensure that steam enters the turbine at an appropriate pressure and improve energy conversion efficiency; At the exhaust port, by controlling the exhaust pressure and optimizing the back pressure conditions of the turbine, the overall performance of the unit is improved. In some industrial production processes, precise control of steam pressure is required to meet specific process requirements. The pressure control function of WOODWARD 505 can adjust steam pressure in real time according to process settings, ensuring the stability of the production process and product quality.
Pressure protection mechanism: When the pressure exceeds the preset safety range, it can quickly trigger protective actions, such as closing the intake valve, adjusting the operating conditions of the turbine, etc., to prevent damage to equipment caused by abnormal pressure and ensure the safety of equipment and personnel. In industries such as chemical and refining, the pressure safety of steam systems is crucial. Once the pressure loses control, it may cause serious safety accidents. The pressure protection mechanism of 505 can respond to abnormal situations in a timely manner and avoid accidents.
（3） Load control and limitation
Flexible load regulation: The load of the steam turbine can be precisely controlled according to actual needs, which can achieve constant load operation and meet some application scenarios with high requirements for power output stability; It can also dynamically adjust the load according to external instructions or system requirements to adapt to changes in different working conditions. In the cogeneration system, the steam turbine needs to adjust the load in real time according to changes in thermal and electrical loads. WOODWARD 505 can quickly respond and accurately adjust, achieving efficient and comprehensive utilization of energy.
Load limiting function: In order to prevent overload operation of the steam turbine, a load limiting function is set. Based on the rated parameters and actual operating conditions of the equipment, a load upper limit can be set. When the load approaches or exceeds the upper limit, automatic adjustment measures such as reducing the intake air volume, lowering the speed, etc. are taken to protect the steam turbine from overload damage and extend the service life of the equipment. In industrial production, there may be temporary peaks in electricity or heat consumption, which may cause the load of the steam turbine to rise instantly. The load limiting function of 505 can effectively prevent the steam turbine from shutting down or being damaged due to overload, ensuring the continuity of production.
（4） Start and stop control
Multiple startup modes: Provides various startup programs such as manual, semi-automatic, automatic, and remote control. The manual start mode provides operators with sufficient on-site control and is suitable for scenarios that require fine tuning or specific operational procedures; The semi-automatic start mode achieves automation in some key steps, simplifying the operation process while retaining a certain amount of manual intervention space; The automatic start mode can automatically complete the start-up process of the steam turbine according to the preset program, including a series of complex operations such as warm-up, speed increase, and grid connection, greatly improving the accuracy and efficiency of start-up; The remote control mode allows operators to perform start-up operations through communication networks in control rooms or other locations far from the turbine, facilitating centralized monitoring and management. In some large industrial facilities, the start-up of steam turbines requires strict adherence to specific operating procedures. The multiple start-up modes of WOODWARD 505 can meet the needs of different scenarios, ensuring a safe and reliable start-up process.
Safe shutdown function: When abnormal conditions are detected (such as overspeed, overload, abnormal pressure, etc.) or shutdown instructions are received, the shutdown operation can be quickly executed. By closing the intake valve, triggering the emergency braking device, and other measures, the turbine can stop running quickly and safely, avoiding further expansion of the accident. In emergency situations, a fast and reliable shutdown function is the last line of defense to ensure the safety of equipment and personnel. The 505’s safety shutdown mechanism can respond and execute shutdown operations in a very short time, minimizing losses to the greatest extent possible.
Working principle
WOODWARD 505 achieves precise control of steam turbines through its built-in microprocessor and a series of complex control algorithms. Its working process is mainly based on the principle of closed-loop control, which collects various operating parameters of the steam turbine in real time (such as speed, pressure, temperature, etc.), compares these parameters with the preset set values, and calculates the deviation between the two. Then, the microprocessor processes the deviation according to a pre-set control algorithm (such as PID control algorithm), generates corresponding control signals, and after amplification, conversion and other processing, transmits them to the actuator of the steam turbine (such as electro-hydraulic converter, regulating valve, etc.). By adjusting the action of the actuator (such as the opening of the regulating valve), the operating state of the steam turbine is changed, so that the actual operating parameters of the steam turbine gradually approach the set values, achieving stable and accurate control.
For example, in the process of speed control, the speed sensor installed on the turbine shaft transmits the real-time detected speed signal in frequency form to WOODWARD 505. The internal frequency/voltage converter of 505 converts the frequency signal into the corresponding voltage signal, and then compares it with the preset speed setting value to calculate the speed deviation. The microprocessor calculates the deviation based on the PID control algorithm and generates a control signal. The control signal is output to the electro-hydraulic converter (I/H or CPC) in the form of a 4-20mA current signal. The electro-hydraulic converter converts the current signal into the corresponding secondary oil pressure (usually 0.15-0.45MPa), which acts on the throttle spool valve to control the opening of the regulating valve, change the steam flow entering the turbine, and ultimately achieve the regulation of the turbine speed to stabilize it near the set value.
Key advantages
（1） High user configurability
