Core Functions
- Core Control Functions
As a key component in the Mark VI system, it performs real-time turbine control. Using pre-set control algorithms, it precisely regulates key turbine parameters (speed, load, pressure, temperature, etc.). For example, in controlling steam turbines in thermal power plants, the module adjusts steam flow and inlet valve opening in real time based on grid load demand, ensuring stable turbine operation within specified operating conditions and maintaining a dynamic balance between output power and system requirements. - Comprehensive Signal Processing and Conversion
The module receives analog signals (such as current or voltage signals for temperature, pressure, and flow) and digital signals (such as device status switches and alarm contact signals) from field sensors via connectors such as P1. The module converts these analog signals into digital signals using an internal analog-to-digital converter (ADC) for CPU processing. Furthermore, the module converts these processed control commands back into analog signals using a digital-to-analog converter (DAC), or directly outputs digital signals to drive actuators (such as control valves and relays), achieving closed-loop control of the turbine's operating status. - Multiple Safety Protection Mechanisms
The module integrates comprehensive turbine protection features, providing real-time monitoring of system abnormalities (such as overspeed, overtemperature, overpressure, excessive vibration, and low oil pressure). When parameters are detected exceeding safety thresholds, the module immediately triggers protection logic, rapidly cutting off the fuel supply, closing the intake valve, and initiating an emergency shutdown (ETS) to prevent equipment damage or accidents. Furthermore, within the triple-redundant system architecture, the module supports a multi-controller signal voting mechanism. By comparing input data from the three redundant controllers, it eliminates erroneous signals, ensures the reliability of output commands, and enhances system fault tolerance.
