Comparative Performance Evaluation of Orthogonal Signal Generators Based Single Phase PLL Algorithms A Survey
The orthogonal signal generator based phase locked loops (OSG PLLs) are among the most popular single phase PLLs within the areas of power electronics and power systems, mainly because they are often easy to be implemented and offer a robust performance against the grid disturbances. The main aim of this paper is to present a survey of the comparative performance evaluation among the state of the art OSG PLLs (include Delay PLL, Deri PLL, Park PLL, SOGI PLL, DOEC PLL, VTD PLL, CCF PLL, and TPFA PLL) under different grid disturbances such as voltage sags, phase, and frequency jumps, and in the presence of dc offset, harmonic components, and white noise in their input. This analysis provides a useful insight about the advantages and disadvantages of these PLLs. The performance enhancement of Delay PLL, Deri PLL, and CCF PLL by including a moving average filter into their structure is another goal of this paper.
