AI Technical Summary
Existing small steam turbine control systems lack human-machine interaction, have low control precision and poor reliability, cannot respond quickly, and lack electronic protection measures, making it difficult to meet the requirements of modern industry for control precision and automation.
A closed-loop control method is adopted. By acquiring the turbine's operating data and target values, control commands are generated to regulate the air valves. The EH oil pressure and safety oil pressure switches are used to determine the starting conditions. The LVDT sensor is used to detect the displacement of the hydraulic actuator, thereby realizing the automated control and protection of the turbine.
It achieves full automation of the steam turbine unit, improves control accuracy and reliability, meets the requirements for rapid control, reduces costs, and has electronic protection functions.
