| Abstract |
This paper offers an overview of the passive
methods used for islanding detection. A monitoring PLL has
been adopted for the estimation of the voltage amplitude
and frequency. Passive inverter resident methods discussed
are the over/under voltage (OUV), over/under frequency
(OUF), the voltage harmonic monitoring (with a study on
the effects of the grid impedance value and of the inverter
dc voltage ripple) and the phase monitoring (different from
the classical phase jump method). A harmonic
synchronization PLL is used to monitor the 3rd, 5th and 7th
harmonics. All the proposed algorithms are validated by
simulations and experimental results obtained in
accordance with the IEEE Std. 929-2000 procedure. |
