초록

A wind farm is described in which two or more windmills are provided with each having a generator to generate electrical power. The energy supplied by the generators is output to a general a.c. grid which is set at a standard voltage. The electrical power supplied by the windmills is injected into the a.c. grid via a d.c. interconnecting grid to which a plurality of windmills are linked and with a converter. The d.c. voltage in the d.c. interconnecting grid is set as a function of the electrical power to be generated by a generator.
