ZAMBELLI PHOTOVOLTAIC PROJECT : MONITORING AND OPERATINAL IMPROVEMENT. SOFTWARE PLANT CONTROL HARDWARE AND SOFTARE

Cel

SINCE JUNE 1985 THE ZAMBELLI PHOTOVOLTAIC PUMPING STATION FEEDS DRINKING WATER TO A VILLAGE RESERVOIR IN THE LESINIA MOUNTAIN AREA NEAR VERONA, LOCATED 350 METRES ABOVE PLANT LEVEL. THE SPECIFIC DESIGN OF THIS STAND-ALONE, UNATTENDED AND COMPLETELY AUTOMATIC PV PLANT, LED TO THE DEVELOPMENT OF A POWER CONDITIONING AND CONTROL SYSTEM CHARACTERIZED BY MAXIMUM POWER TRACKING VARIABLE FREQUENCY INVERTERS POWERING 2 AC DRIVEN PISTON PUMPS.
HOWEVER, OPERATIONAL EXPERIENCE REVEALED THE NEED TO IMPROVE PLANT PERFORMANCE AS FOR FREQUENT START-STOP CYCLING AND NOT OPTIMUM POWER MANAGEMENT AND CONTROL. ALSO, SINCE NO DATA WERE TRANSMITTED FROM THE PLANT TO A.G.S.M. HEADQUARTERS LOCATED 30 KM AWAY, THE STATUS OF THE SYSTEM WAS NOT KNOWN TO CONTROL ROOM OPERATORS, AND SMALL AND MOSTLY NOT SIGNIFICANT FAILURES TENDED TO TRIGGER OFF ALARMS RESULTING IN AUTOMATIC PLANT SHUT-DOWN, REQUIRING MANUAL RESET/RESTART BY MAINTENANCE STAFF.
ACCORDINGLY, THE PROJECT IN SUBJECT IS INTENDED TO IMPROVE PERFORMANCE AND RELIABILITY OF THE SYSTEM BY REPLACING AND OPTIMIZING THE LOCAL CONTROLLER, AND BY INSTALLING A REMOTE SENSING SYSTEM ALLOWING TO PERFORM DATA MONITORING DIRECTLY FROM AGSM HEADQUARTERS VIA PHONE-LINE (MODEM).
THE IMPROVED SYSTEM SHALL BE MONITORED OVER A 24 MONTH PERIOD, INCLUDING PERIODICAL CHECKING OF PV ARRAY AND BATTERY PERFORMANCE.
