A hybrid wind-photovoltaic system has been operated in the Zentrallager of the Plus-Warenhandelsgesellschaft in Ottendorf-Okrilla (Saxony) since 1992. A 60 kW wind energy converter of Tackes TW-60 type has been combined with a 3.18 kW photovoltaic system. Some special features of the pv system (orientation of the generator, master-slave operation of the inverters) are remarkable. The operation of both systems was investigated in detail. With a yield of 689 kWh/kW(sub p)a in 1995 the pv system achieved comparable results with other grid coupled pv systems in Saxony. Possible better results are prevented by the selected generator orientation. The master-slave mode of the inverter was studied in detail. The nonoptimal relation between the generator size and the inverters influenced the results. The wind energy converter achieved in 1995 a yield of 990 kWh/kW, which is below average also for non coast areas. The result is influenced by many obstacles in the surrounding of the converter. The time availability of the hybrid energy system in 1995 was 71.5% (6260 hours). (orig.)
