Role in the System: As a key component of the Mark V series turbine control system, the DS200TCCAG1BAA module helps realize analog input and output functions, plays a crucial role in ensuring precise monitoring and control of turbine operation, and also contributes to smooth communication between the three controllers in the Mark V series.
Specific Application Cases:
Steam Turbine Control System: In a large power plant, the DS200TCCAG1BAA module is used in the control system of the steam turbine. It is responsible for collecting analog signals such as steam pressure and temperature, converting these signals into digital quantities and transmitting them to the central processing unit of the control system. According to the instructions issued by the processor, the module can also output analog signals to control the opening of the steam control valve, thereby accurately adjusting the steam flow, ensuring the efficient and stable operation of the steam turbine, and guaranteeing the stability of power generation efficiency and power supply.
Gas Turbine Monitoring System: In a natural gas power station, the operation of the gas turbine requires precise monitoring and control. The DS200TCCAG1BAA module has played an important role here. It collects real-time analog signals such as the speed of the gas turbine, gas temperature, and fuel flow, and provides accurate operating parameters for operators after processing. At the same time, the module outputs analog signals according to the control algorithm to adjust the fuel injection amount and air intake of the gas turbine, so that the gas turbine can maintain the best operating state under different loads, improve energy utilization efficiency, and reduce emissions.
Wind Turbine Control System: In offshore wind farms, the control system of wind turbines needs to adapt to complex marine environments and variable wind conditions. The DS200TCCAG1BAA module, as an analog I/O module, is used to collect analog signals such as wind speed, wind direction, and nacelle temperature of the wind turbine, providing data support for the pitch control system and yaw control system of the turbine. By precisely controlling the pitch and yaw angles, the wind turbine can capture wind energy to the maximum extent, improve power generation efficiency, and ensure the reliable operation of the turbine in harsh environments.
