Prosig have been awarded the contract to upgrade the Online Vibration Monitoring System at Wylfa nuclear power station.
Wylfa is located on the north coast of Anglesey and has two Magnox design nuclear reactors and four turbine generators. The station supplies 23 million kilowatt hours of electricity, enough to meet the needs of two cities the size of Liverpool and Manchester put together.
A PROTOR system has been installed and running Wylfa since 1998. The system monitors the four main steam turbine generators and also eight gas circulators, four for each of the two reactors. The system provides important vibration trends for these critical items of plant for both local and remote analysis.
The new contract is to replace the existing PROTOR-3 Remote Monitoring Data Analysis Systems (RMDAS) with new PROTOR-4 P4700 units. A total of eight P4700 units will be supplied, one for each main turbine and one to monitor a pair of Gas Circulators. The flexibility of the P4700 in handling multiple machines with individual tachometer or phase reference signals is ideally suited to this requirement.
my M.E. project on online vibration monitoring of wind power plant. then, u can send detail information on Online Vibration Monitoring System At Wylfa.
thanking you.
Hi prashant, Thanks for your comment. You might find the following links helpful for your project. A couple of articles for and against condition monitoring of wind turbines…

Hi Prashant,
Wylfa is a nuclear power station in UK. Prosig supplied a complete PROTOR online vibration monitoring system for the condition monitoring of their main steam turbines and also the critical gas circulators. The PROTOR system takes in vibration data from both pedesatal velocity transducers and shaft proximity probes and analyzes these relative to a tachometer or phase reference signal. PROTOR allows the main harmonic components of the vibration to be extracted, trended and alarm processed, it also allows data to be correlated to various plant process parameters. More details on PROTOR can be found at http://www.prosig.com/protor
