NEW DEVELOPMENTS IN FRENCH TRANSIENT MONITORING-SYSTEM - SYSFAC FROM THE EXPERIMENTS TO THE INDUSTRIAL-PROCESS

After more than 15 years of experience with regulatory transient data collection, Electricite de France decided to design a new concept of f atigue monitoring system called SYSFAC. This new system is the result of seven years of successful experimentation with fatigue meters. This system will be connected to the on-site data acquisition system witho ut any complementary instrumentation. The SYSFAC system has a modular structure: the mechanical transient module, the functional transient m odule, the fatigue meters module and the global damage computing modul e all have a high level of flexibility to be applied to various types of circuits. After the preliminary studies had been achieved, it was d ecided to undertake the industrial phase of the SYSFAC project. Specif ic codes on PC computers have been used to validate the basic concepts and the operator interface. Real-size coding will last one year and t he first SYSFAC system will be delivered to the pilot power plant by t he end of 1995.
