Under distorted grid conditions with high bandwidth, synchronous reference frame (SRF) Phase Lock Loop (PLL) is able to work properly but increased bandwidth introduces harmonics which affect the PLL output and SRF PLL is also not able to produce accurate phase information under distorted grid conditions. This paper suggests a new phase detection technique based on cosine look-up table (cLUT) using...
The energy transfer between Power Electronic Converters (PEC) and grid is improved by proper design of synchronization techniques. Phase Lock Loop (PLL) is used to estimate the grid phase angle. The challenges associated with the design of PLL are how fast the phase angle and frequency are estimated and synchronized under ideal as well as non-ideal grid conditions. Synchronous Reference Frame (SRF)...
Power produced from the Renewable Energy Sources (RES) is directly feeding to the electric grid via Power Electronic Circuits (PEC). Grid connected solar Photovoltaic (PV) system requires a high quality of grid monitoring techniques in order to detect the phase angle, voltage magnitude and frequency and also to meet standard specifications in terms of achieving power quality and safety. Various techniques...
