III. Key Features
- High-precision closed-loop regulation of turbine speed and load realizes stable unit startup, grid-connected frequency modulation and anti-runaway load rejection control.
- Decoupled compound control for extraction turbines balances power generation efficiency and industrial heating process requirements.
- Multi-dimensional safety interlock and fault fail-safe mechanism effectively avoids major safety accidents such as turbine out-of-step and equipment burnout.
- Integrated local HMI and remote network communication realize full-cycle intelligent operation, maintenance and fault diagnosis.
- Offline simulation debugging and hierarchical password authority management reduce on-site commissioning risks and prevent unauthorized misoperation.
IV. Working Principle
After power-on self-test of power supply, I/O, communication and display circuits, the controller loads solidified user configuration parameters and enters standby mode. During unit startup, it drives the steam valve actuator according to the preset acceleration rate, collects real-time speed signals through dual sensors, and uses adaptive PID algorithm to close-loop correct valve output to stabilize turbine speed. After grid connection, it switches to load or extraction pressure control mode to realize multi-parameter coordinated regulation. Once faults such as overspeed and signal loss occur, the controller locks the valve at the safe position, triggers ETS emergency shutdown, latches fault information and uploads timestamped event logs for accident analysis.
V. Application Scenarios
- Waste heat, biomass and captive power plants: Turbine speed governing, grid-connected frequency regulation and safety interlock protection.
- Petrochemical industry: Process drive turbine and waste heat recovery turbomachinery automatic control system.
- Cogeneration heating power plants: Back-pressure and extraction turbine heat-power coordinated regulation.
- Cement and paper industrial power plants: Industrial turbine sequence control and equipment fault safety protection.
- Legacy control system technical renovation: Digital upgrading of old analog governors and early 505 series controllers.
