Objective
The Kythnos photovoltaic power plant has been in operation since 1983 and has a capacity of 100 kWp. During the last 2 years, various improvements have been made to the system. A new reliable line commutated 6-pulse thyristor inverter has been installed. At 170 V direct current, the efficiency of the inverter was 93% at full load. New lightning protection has been added. Rods have been placed around the generator to prevent direct strikes, and arrestors have been installed at both ends of the cabling between the generator and the converter to block transients. New data monitoring units have been installed. The isolated situation of the plant demands reliable automatic supervision and monitoring.
Maximum power point regulation ensures that the maximum power is always extracted from the arrays. The possibility of altering the tilt angle of the arrays seasonally to increase output has been investigated.
