| Abstract |
The base of our new developed grid-connected PV
converter is a low cost general purpose frequency converter.
In spite of the lack of voltage sensors a very reliable antiisland
protection is reached. In the first section a control
structures of the grid-connected converter with UVOC
(Utility Voltage Oriented Control) is given while in the
second section a method for the sensorless identification of
the grid voltage is suggested. The third section describes an
ultimate method for anti-island protection with a negligible
none-detection zone. Finally the experimental results of the
developed low cost general purpose frequency converter are
presented. |
