DIAGEN~R - Generator Diagnostics in Real Time

摘要

THE DIAGEN~R SYSTEM IS A NEW DIAGNOSTIC TOOL ABLE TO MONITOR IN REAL TIME THE GENERATOR CONDITIONS, BEHAVIOUR AND SAFETY. DIAGEN~R IS A MODULAR AND EMBEDDED APPARATUS CAPABLE TO COLLECT, STORE AND ANALYSE DATA FROM DIFFERENT KIND OF SENSORS APPLIED TO THE GENERATOR COMPONENTS. DIAGEN~R CAN EVALUATE PARTIAL DISCHARGES, STATOR WINDING, SHAFT AND BEARINGS VIBRATIONS, INTERTURN SHOT CIRCUITS IN THE ROTOR WINDING, SHAFT CURRENT AND VOLTAGE . IT'S POSSIBLE TO INSTALL THE APPARATUS ON ALL GENERATOR TYPE (TURBO AND HYDRO), OF EVERY TECHNOLOGY AND MANUFACTURER. DIAGEN CAN : 1. PERFORM CONTINUOUS AND REAL TIME ON LINE ACQUISITION. 2. ANALIZE DATA IN REAL TIME. 3. TREND ALL THE GENERATOR SAMPLED PARAMETERS. 4. SHOW AND GET ALARMS IN CASE OF ABNORMAL SITUATION. MOREOVER IT ALLOWS REMOTE WEB CONNECTION TO ANSALDO GENERATOR DIAGNOSTIC EXPERTS IN ORDER TO HELP THE POWER PLANT MAINTENANCE TECHNICIANS TO EVALUATE THE BEHAVIOUR OF THE ELECTRICAL MACHINE. THE WHOLE SYSTEM IS BASED ON A FPGA AND A REAL TIME PROCESSOR. SIGNALS CAN BE TRANSFERRED TO THE CONTROL ROOM USING THE POWER PLANT ETHERNET BY TCP/IP WITH A DEDICATED SOFTWARE OR BY OPC. DIAGEN~R ALLOWS PREDICTIVE DIAGNOSTICS TO REDUCE FAULT RISKS AND IT CAN BE EASILY INSTALLED ALSO ON OPERATED MACHINES AS RETROFIT DURING OVERHAULS. THE COST SAVING IS AN IMPORTANT BENEFIT: IN FACT THERE IS NO NEED FOR GENERATOR SPECIALISTS TO BE IN SITE FOR MEASUREMENTS AND EVALUATIONS; OPERATION INTERRUPTIONS AND RISKS OF UNPLANNED OUTAGES CAN BE AVOIDED WITH DIAGEN~R SURVEILLANCE.
