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 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.

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 ...

Pre-Synchronization Control Strategy for Grid Connection of Synchronverter Cluster
2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021It is found that large inrush currents and power oscillations occur when a synchronverter cluster is connected to the utility grid. In this paper, we propose a pre-synchronization control strategy to minimize the inrush current and suppress the power oscillation in the grid-tied synchronverters.

Memory Pre-synchronization Technology for Application Migration
2012 IEEE 12th International Conference on Computer and Information Technology, 2012The rapid development of internet technology and mobile communication technology has brought significant changes to the way in which people retrieve information and experience application service. We believe that application migration can perfectly solve these problems, if the continuity of application service experience and efficiency of migration ...

Synchronization Process and a Pre-synchronization Method of the Virtual Synchronous Generator
2020 4th International Conference on HVDC (HVDC), 2020Virtual synchronous generator (VSG) is the concept of controlling the grid-connected inverters to mimic conventional synchronous generators (SGs), and it is considered to be a promising method to enhance the grid inertia and power regulation ability when the renewable energy has a high penetration rate in the grid.
