中文摘要:

本文建立了基于VSC-MTDC的风电场并网三端系统，充分利用直流响应可控性强，速度快的优点，根据柔性直流输电对有功功率和无功功率独立、快速控制的特点，提出了用VSC-HVDC与发电机调速器协调控制的方法，通过对定有功功率控制器附加频率控制来提高交流系统频率稳定性。理论分析和仿真结果表明该控制策略能提高多端柔性直流输电系统的频率调整能力，当系统受到扰动时，能有效的改善系统频率稳定性。

英文摘要:

This paper constructs a three-terminal system connecting wind farm based VSC-MTDC. DC response have the advantages of strong and fast controllability, VSC-HVDC have the characteristics of control active power and reactive power independently and quickly.Therefore, a coordinated control method of VSC-HVDC and governor is presented in this paper, in virtue of setting additional frequency control in the constant active power controller to improve AC system frequency stability.Theoretical analysis and simulation results show that the proposed control strategy can improve the frequency adjustment ability of multi-terminal HVDC system,it can effectively improve the system frequency stability when the system is disturbed.
