PHOTOVOLTAIC PILOT PLANT OF VULCANO - SPECIFIC ACTIONS

Objective



THE RATED PEAK POWER OF THE VULCANO PLANT IS ABOUT 80 KW.
THE MAIN FEATURE OF THE PLANT LIES IN ITS DUAL OPERATING MODE: EITHER STAND-ALONE OR GRID-CONNECTED.
THE PLANT, COMMISSIONED HALF-WAY THROUGH 1984, HAS ALWAYS WORKED UNINTERRUPTEDLY AND SATISFACTORILY.
BEGINNING FROM 1987 IT HAS BEEN CONSIDERED WORTH CARRYING OUT RESEARCH ON A NUMBER OF SPECIFIC POINTS NOT SO FAR DEALT WITH IN SUFFICIENT DETAIL IN LITERATURE, AS FOLLOWS:
. EXPERIMENTAL RESEARCH ON THE DETERIORATION, OVER A PERIOD OF TIME, IN THE CHARACTERISTICS OF THE MODULES OF THE PLANT.
. THEORETICAL AND EXPERIMENTAL RESEARCH ON THE PLANT'S ELECTROCHEMICAL STORAGE SYSTEM.
THE RESEARCH ON THE SECOND OF THE ABOVE SUBJECTS HAS A NUMBER OF AIMS:
- TO IMPROVE METHODS OF CHECKING THE STATE OF CHARGE OF BATTERIES IN NEWLY-DESIGNED PHOTOVOLTAIC PLANTS
- TO IMPROVE THE WAYS IN WHICH THE VULCANO BATTERY STORAGE SYSTEM IS OPERATED
- TO MONITOR AND MAKE A CAREFUL DIAGNOSIS OF THE CONDITION OF THE PLANT'S BATTERY.
THE METHODOLOGY FOR THE "ON-LINE" DETERMINATION OF THE BATTERY SOC HAS BEEN CHECKED AT THE CESI LAB DURING THE 1988 YEAR; IN THE MEANWHILE THE HARDWARE AND THE SOFTWARE OF THE EXPERIMENTAL FACILITY TO ACCOMPLISH THE RESEARCH HAVE BEEN PREPARED AND INSTALLED AT THE VULCANO PLANT.
ADDITIONAL TESTS CONDUCTED ON THE SPOT AT THE VULCANO PLANT SHOWED THAT FEW CELLS OF THE BATTERY LOST A PART OF THEIR INITIAL CAPACITY AFTER FOUR YEARS OF OPERATION.
