Overview of Steam Turbine Control
Honeywell Enraf Tank Gauging's Driver Control system offers steam turbine control applications that effectively regulate turbine speed and ensure safe operating parameters, such as maintaining inlet steam pressure within safe limits. These applications support automated start-up/shutdown sequencing, overspeed protection, and critical speed avoidance, providing stable and accurate speed control for improved production and uptime.
Key Features and Functionality
The steam turbine control applications from Honeywell Enraf Tank Gauging include speed and extraction controls that continuously regulate the rotational speed of a steam turbine. These controls are equipped with advanced algorithms to ensure high control accuracy and machinery protection. The applications can be configured for various API 612 Special Purpose turbines, including single valve, multi-valve, and extraction/admission turbines. Key features include overspeed avoidance, automatic start and stop sequencing, critical speed avoidance, breakaway control, automatic warm start-up sequencing, and variable loop gain.
Benefits and Solutions Provided
The steam turbine control applications solve critical issues by increasing uptime through fast and accurate PID controls, loop decoupling, and overspeed protection. This helps prevent costly downtime, even in the event of sudden load loss. Additionally, the automated sequences, including critical speed avoidance, ensure safe, reliable, and repeatable start-ups and shutdowns, thus preventing damage to the turbine and enhancing overall efficiency and reliability.
