Key Core Functions

• High-Precision Turbine Speed Regulation Control: The module integrates Woodward's exclusive turbine speed control algorithm, the speed control accuracy can reach within ±0.05% of the rated speed, which can stably control the turbine speed fluctuation within a very small range, effectively ensuring the stable operation of the generator set frequency and the compressor unit working condition.
• Multi-Unit Synchronous Load Distribution Management: The controller supports multi-generator set parallel operation control, which can automatically realize equal-proportion load distribution according to the capacity of each unit, and complete the grid synchronization operation within 1 second, effectively improving the operation efficiency of the whole power generation system.
• Full-Coverage Safety Protection Mechanism: The module has built-in multi-level safety interlock protection logic, which can quickly trigger the emergency trip protection action when the turbine has abnormal states such as overspeed, over-temperature, oil pressure loss and vibration over-limit, and the protection action response time is less than 5ms, effectively avoiding major equipment damage accidents of the turbine unit.
• Perfect System Compatibility: The module is fully compatible with Woodward 2301, 500 series, NetCon and other classic turbine control systems, can seamlessly connect with the existing system actuators, speed sensors and operation panels, no need to replace the existing system hardware in large quantities, which can be directly used as spare parts for the maintenance and replacement of old Woodward turbine control systems that have been in operation for many years, effectively extending the service life of the old control system.
• Full Self-Diagnosis and Fault Locating: The module continuously performs real-time all-round health monitoring on the operation state, sensor signal state and communication link state, automatically identifies abnormal states such as sensor signal loss, communication interruption, module hardware fault, and uploads fault alarm information to the upper monitoring platform in time, helping maintenance personnel quickly locate system hidden dangers and effectively shorten the system fault recovery time.

Typical Application Scenarios

• Power industry: Large-scale gas turbine/steam turbine generator set control system, responsible for the core speed regulation, load distribution and safety protection control of the unit.
• Petrochemical industry: Large natural gas long-distance transmission trunk line centrifugal compressor unit control system, realizing stable and reliable speed regulation and working condition control of the compressor.
• Oil & gas industry: Large refinery flue gas turbine unit control system, realizing high-reliability operation control of the flue gas turbine under high-temperature and high-corrosion working conditions.
• Industrial automation industry: Large industrial diesel engine/gas engine generator set control system, realizing efficient energy-saving operation control of the unit.
• Industrial transformation and upgrading projects: Spare parts replacement and system maintenance of old Woodward turbine control systems that have been in operation for many years in various industrial sites.

Installation and Maintenance Guidelines

• Strict anti-static protection must be implemented before installation: operators must wear a reliably grounded anti-static wrist strap to avoid static electricity damaging the precision processor and control chips on the board.
• The sensor signal wiring must strictly follow the Woodward turbine control system wiring specifications, use dedicated double-shielded twisted-pair signal cables, and the shielding layer must be reliably single-ended grounded, and the high-voltage power wiring and low-voltage signal wiring must be routed separately to avoid electrical interference affecting the control accuracy.
• After installation, perform full function test and turbine no-load/load test of the controller through the dedicated Woodward engineering software, confirm that the speed regulation function, load distribution function, protection interlock function and communication function of the module fully meet the system design requirements.
• Regularly check the operation status indicator of the module during daily operation, regularly clean the dust accumulated on the surface of the circuit board every 2 years, which can effectively extend the service life of this modular controller to more than 15 years.
