Comparison of Synchronization Techniques Under Distorted Grid Conditions

IEEE Access, 2019
In grid-connected power converter applications, the phase-locked loop (PLL) is probably the most widely used grid synchronization technique, owing to its simple implementation. However, in power grids some very common problems, such as voltage distortion,

Real-time interharmonics detection and measurement based on FFT algorithm

, 2009
The modern power systems are supplying an increasing number of non-linear loads like: double conversion systems, arc furnaces, arc discharging, high power Cycloconverter (CCV) etc. These loads are harmonics and interharmonics sources.

Investigation and Suppression of Harmonics and Interharmonics in High-Power PWM Current-Source Drive Systems

, 2015
Among the medium-voltage (MV) high-power industrial drive applications, the PWM current-source drive systems are increasingly used in recent years, due to the simple structure, motor friendly waveforms and fuseless short-circuit protection.

Effect of voltage subharmonics and interharmonics on currents of line start permanent magnet synchronous motor

Technical Transactions
This study deals with currents of a line start permanent magnet synchronous motor (LSPMSM), supplied with voltage containing subharmonics and interharmonics – components of the frequency less than the fundamental frequency or not being equal to its ...
