Abstract EN
High performance synchronization methord is citical for grid connected power converter.
For single-phase system, power based phase-locked loop(pPLL) uses a multiplier as phase detector(PD).
As single-phase grid voltage is distorted, the phase error information contains ac disturbances oscillating at integer multiples of fundamental frequency which lead to detection error.
This paper presents a new scheme based on moving average filter(MAF) applied in-loop of pPLL.
The signal characteristic of phase error is dissussed in detail.
A predictive rule is adopted to compensate the delay induced by MAF, thus achieving fast dynamic response.
In the case of frequency deviate from nomimal, estimated frequency is fed back to adjust the filter window length of MAF and buffer size of predictive rule.
Simulation and experimental results show that proposed PLL achieves good performance under adverse grid conditions.
