Pre-synchronization of AVS audio-video based on Real-Time Transport Protocol
2012 International Conference on Wireless Communications and Signal Processing (WCSP), 2012After analyzing the working principle of Real-Time Transport Protocol (RTP)/Real-Time Transport Control Protocol(RTCP), the feature of AVS system and the deficiencies of the existing synchronization methods, we propose a new pre-synchronization method for synchronizing audio and video in this paper.

Research on Pre-Synchronization Control Strategy of Optical Storage VSG Off-Grid Switching
Review of Computer Engineering Studies, 2022In the optical storage DC microgrid in island mode, in view of the large inrush current problem of the inverter controlled by the optical storage VSG when switching from off-grid to grid-connected operation mode, a pre-synchronization control strategy based on secondary frequency regulation and voltage regulation was proposed.

Parameters Design of Pre-synchronization for Multiple Virtual Synchronous Generator Based Microgrid
2019 IEEE Applied Power Electronics Conference and Exposition (APEC), 2019A pre-synchronization method for microgrids based on virtual synchronous generators has been presented to reduce inrush current and achieve seamless transition from islanded mode to grid-connected mode. And pre-synchronization units that consist of a frequency regulator, a voltage magnitude regulator and a phase regulator is added to each inverters in ...

A Pre-synchronization Method for Grid-connection Based on Virtual Synchronous Generator
2019 6th International Conference on Systems and Informatics (ICSAI), 2019The inverter is simulated as a synchronous generator that is friendly to large power grid, which can improve the absorption capacity of distributed power supply. However, when virtual synchronous generator (VSG) is connected to the grid, there will be a large current shock. Therefore, this paper proposes an improved pre-synchronization control strategy

Pre-synchronization method for grid-connection of virtual synchronous generators based micro-grids
2017 19th European Conference on Power Electronics and Applications (EPE'17 ECCE Europe), 2017Since the photovoltaic power generation, wind power and other distributed power supply are volatile and random, they will affect the stability of the grid frequency. In order to improve the voltage and frequency in micro-grid, the virtual synchronous generator control strategy is proposed for inverter control, which can emulate the behavior of ...

Pre-synchronization is necessary to reconnect microgrid to utility grid in order to avoid inrush current. The droop control is widely adopted for the operation of microgrid in islanded mode as it ensures power sharing in a decentralized way without critical communication, but during pre-synchronization it needs communication with every inverter to ...

Design of a Low Power Pre-synchronization ASIP for Multimode SDR Terminals
2007SDR enables cost-effective multi-mode terminals but still suffers from significant energy penalty when compared to dedicated hardware solutions. At system level, this energy bottleneck can be leveraged capitalizing on heterogeneous MPSOC platforms where specific engines are dedicated to classes of functions with similar computation characteristics and ...
