Now this turbine is extraction-condensing type turbine with the condensate of the condensing section going to the surface condenser. HEINZMANN developed the VOP O3 unit to monitor 3 speed probes with 2 out of 3 voting to protect the machinery. Today, most speed trip systems incorporate magnetic speed input signals and two out of three voting for increased reliability. To understand the difference between the two types of protection, it is important to understand how mechanical overspeed protection works. 6T@ppAAp:t'N:'! r WebThe overspeed test can be made at any time as long as the turbine operating limits are not exceeded. The set speed for operating the over speed trip can be adjusted by adding washers below the spring and then adjusting their compression pressure. Secondly, a measuring surface (gear) is mounted on the shaft if this is not already available, after which one or more sensors are placed around this measuring surface. A multi-valve, multi-stage turbine protection system incorporates a mechanical overspeed device (trip pin) to shut down the turbine on overspeed (10 percent above maximum continuous speed). PowerGen 2023 Session Notes: Flexibility in Combined-Cycle Plant Performance (CCPP), Reporting from PowerGen 2023: The H2-Orange Initiative, From PowerGen 2023: Gas Turbine Performance Evaluations, Turbomachinery International Readership Survey.
