  • VSC-Based HVDC Power Transmission Systems: An Overview
    IEEE Transactions on Power Electronics, 2009
    Co-Authors: Nikolas Flourentzou, Vassilios Georgios Agelidis, Georgios D. Demetriades
    Abstract:

    The ever increasing progress of high-voltage high-Power fully controlled semiconductor technology continues to have a significant impact on the development of advanced Power electronic apparatus used to support optimized operations and efficient management of electrical grids, which, in many cases, are fully or partially deregulated networks. Developments advance both the HVDC Power Transmission and the flexible ac Transmission system technologies. In this paper, an overview of the recent advances in the area of voltage-source converter (VSC) HVDC technology is provided. Selected key multilevel converter topologies are presented. Control and modeling methods are discussed. A list of VSC-based HVDC installations worldwide is included. It is confirmed that the continuous development of Power electronics presents cost-effective opportunities for the utilities to exploit, and HVDC remains a key technology. In particular, VSC-HVDC can address not only conventional network issues such as bulk Power Transmission, asynchronous network interconnections, back-to-back ac system linking, and voltage/stability support to mention a few, but also niche markets such as the integration of large-scale renewable energy sources with the grid and most recently large onshore/offshore wind farms.

  • VSC-based HVDC Power Transmission for the large-scale offshore wind Power - a survey
    International Conference on Renewable Power Generation (RPG 2015), 2020
    Co-Authors: W. Du, Q. Fu, H. F. Wang
    Abstract:

    Compared with traditional DC Transmission systems, the VSC-based HVDC Power Transmission system, as a new type of Transmission system performs better in terms of improving Power system stability due to its inherent structural characteristics and it has promising application prospect. In order to guarantee the safety and stability of a Power grid, this paper summarizes the control strategies of both two ends VSC-HVDC system and multi terminal HVDC system (MTDC). Considering large scale wind farms with strong volatility will be integrated and located widely into the system in the near future, control strategies and the stability of the MTDC system will be of great concern. In this paper, the development and currently status of control strategies and stability of MTDC system are reviewed, which will lay a foundation for the further research and application of VSC-HVDC.

  • control and protection strategies for parallel multi terminal HVDC Power Transmission system and their simulation
    Power system technology, 2012
    Co-Authors: Wang Liang
    Abstract:

    Multi-terminal high voltage direct current(MTDC) Power Transmission system can implement Power Transmission or Power exchange between converter stations and the AC Power Transmission systems connecting to the formers.It can also solve the problem of Power Transmission while there are multi Power sources or multi receiving ends.In general,the connection patterns of MTDC can be divided into two forms,i.e.,the connection in parallel and the connection in series.In this paper,the steady-state operation and transient fault process of four-terminal parallel HVDC Power Transmission system are researched.Based on the platform of EMTDC/PSCAD a monopole simulation model is built to carry out the simulation on multi combinations of deblock startup with block-caused outage,and a DC Power balance controller is designed to implement the coordinated Power control among converter stations.Besides,a cooperation mode of the controller with the protection under emergency outage of single converter station or under fault occurred in DC Transmission line is put forward,and simulation results show that the proposed control and protection strategies are effective.
