Description
The T80/T80C single/dual-channel universal turbine controller is a compact turbine machinery control device suitable for various units including waste heat power generation, waste-to-energy power generation, biomass power generation, solar thermal power generation, and industrial traction applications. It provides control strategies such as isolated grid operation, thermal-electric interconnection regulation, steam injection regulation, and sliding pressure operation. The controller's hardware utilizes industrial-grade components compliant with military standard GJB/Z35-93. Its electromagnetic interference resistance meets GJB151A, HJB34-1990, and IEC61000-4 requirements, ensuring long-term stable and reliable operation in industrial environments.
T80/T80C Product Features
● True fully digital electronic governor design (DEH) offers superior interference resistance and built-in servo amplifier functionality, enabling direct drive of common electro-hydraulic converters such as DDV valves, VOITH valves, and CPC valves. Compatible with various hydraulic equipment from original equipment manufacturers.
● Suitable for various power generation units including waste heat, waste-to-energy, biomass, and solar power plants, providing specialized solutions for islanded operation, thermal-electric coupling regulation, and slip-pressure operation.
● Supports multiple communication protocols including MODBUS, DP, and Industrial Ethernet. Standard configuration includes a user-friendly HMI and operator station.
T80/T80C Key Functions
● Speed Control: Unit startup and speed ramping control, primary frequency regulation capability, and isolated grid operation for power generation steam turbines.
● Power Control: Unit load ramping and steady-state load control.
● Extraction Pressure Control: Enables cogeneration coordination, heat-driven power operation control, and power-driven heat operation control.
● Main Steam Pressure Control: Closed-loop control of main steam pressure for waste heat power plants, waste-to-energy plants, solar thermal power plants, etc.
● Automatic Grid Connection: Achieves automatic grid connection with initial load capability when integrated with automatic quasi-synchronization devices.
● Coordinated Control System (CCS): Enables coordinated boiler-turbine control when integrated with DCS systems.
● Over-Speed Protection (OPC): Suppresses speed surge during unit load shedding to prevent turbine tripping.
● Power, main steam flow, and adjustable extraction flow limiting functions. Over-speed protection tests (mechanical/electrical OPC testing), valve operation tests, valve tightness tests, grid connection tests, etc.
● Simulation Testing: T80/T80C controllers feature offline simulation testing capabilities.
