摘　　要：为提高海上全直流风场虚拟同步控制的稳定性,提出基于MMC的海上全直流风场虚拟同步控制方法,构建海上全直流风场的流体密度和压强参数分析模型,结合全直流风流体的速度和网格运动速度的参量估计结果,进行海上全直流风场虚拟同步控制的约束自变量特征分析;通过控制面的单位外法矢量量化特征分析方法,实现对海上全直流风场的数值模拟,采用MMC自适应传感器测量技术,实现对海上全直流风场虚拟同步控制过程中的参数优化解析和估计,实现海上全直流风场虚拟同步的稳定性控制.仿真结果表明:采用该方法进行海上全直流风场虚拟同步控制的稳定性较好,电网频率恢复速度快,且耗能较少.In order to improve the stability of virtual synchronous control of offshore full DC wind field,a virtual synchronous control method based on MMC is proposed.The fluid density and pressure parameter analysis model of offshore full direct current wind field is constructed.Combined with the parameter estimation results of velocity and grid velocity of full direct current wind field,the constrained independent variable characteristics of virtual synchronous control of offshore full DC wind field are analyzed;the numerical simulation of offshore full DC wind field is realized by using the method of vector quantization characteristic analysis of control surface outside unit,and MMC,the adaptive sensor measurement technology,is used to realize the parameter optimization analysis and estimation in the process of virtual synchronous control of offshore full DC wind field,thus the stability control of virtual synchronization of offshore full DC wind field is realized.The simulation results show that the proposed method has good stability,fast frequency recovery and less energy consumption.
