A new twist in torsional vibration shaft monitoring
Entergy invited Suprock to install our TDMS system at their plant due because our wireless powered telemetry is capable of measuring torsional vibrations long term. They have a new upgraded turbine en route and are using the TDMS system to ensure smooth operation till it’s time to install the new rotor train. It was a … Continue reading Waterford 3: Another successful TDMS install
Joe and Francesco took the country roads down to West Virginia and helped our friends at AEP Amos plant with a TDMS install. This was a combined TDMS/pressure sensor install for the purpose of studying a possible steam flow issue and how it may be affecting torsional vibrations and with it, the health of the … Continue reading TDMS install in West Virginia
The situation: Von Mises stress calculations on Hydro unit forced plant operators to run well below rated capacity of 57.5MW. Running at 55MW, the rotor was calculated to be exceeding the material limits of 8000psi shear and 13,333.33psi von Mises combined stress when running at capacity. The solution: live torque monitoring of the shaft (as … Continue reading Success Story: Hydropower output limitation lifted using TDMS data
We would like to extend a thank you to Harold Breitbach of Energiforsk Thermal Engineering Research Institute for including our TDMS system in their report about torsional vibrations in nuclear steam turbine applications. “Vibration problems in nuclear power plants can originate from different sources. One of these is torsional vibrations in shaft trains, which have … Continue reading TDMS torsional vibration system featured in report by Energiforsk
Recently we helped out our neighbors to the north with Hydro TG torsional monitoring in the most prestigious powerhouses in North America. Our friends at OPG were interested in monitoring TG performance and civil structure performance on the Niagara Sir Adam Beck plant. The installations were performed in conjunction with Electric Power Research Institute (EPRI) … Continue reading OPG’s Sir Adam Beck Generating Station
Our TDMS torsional vibration system has been featured in thus month’s EPRI Journal. It outlines how our data from our sensors has helped Duke Energy establish a more comprehensive plan for their upcoming upgrade at Bad Creek Pumped Storage Station. “By using the sensors, we’ve identified frequencies of concern that indicate torsional vibration,” said Duncan. … Continue reading SuprockTech’s TDMS featured in EPRI hydropower journal
This was a particularly challenging telemetry installation that we had the pleasure of solving for AEP nuclear. The installation was conducted in-situ in a bearing housing betwixt an oil deflector plate and the housing wall. The cook bearing 5 site was the grave of previous mortal attempts at telemetry measurements- This was a job for … Continue reading AEP DC Cook Unit 2 install
