电压控制对构网型双馈风机机电时间尺度动态影响建模与机制分析
Modeling and Mechanism Analysis of the Voltage Control Effect on Electromechanical Time-scale Dynamics of the Grid-forming DFIG
摘要
Abstract
The cross-timescale effect rule and mechanism of electromagnetic timescale voltage control on grid-forming DFIG's electromechanical timescale dynamic were studied.Taking DFIG using voltage and current double loop virtual synchronous control strategy as the research object,firstly,the dominant electromechanical timescale model of the system was explored by means of the modal analysis method.And the cross-timescale phenomenon and rule of the influence of electromagnetic timescale voltage control on electromechanical timescale model were found.Then,the research object's excitation-response model and its linearization model were established.And the characteristics of the grid-forming DFIG and the influence path of voltage control involved in the electromechanical timescale dynamics of the system were analyzed.Then,the damping torque analysis method was used to explain the above modal analysis results.Finally,the electromagnetic transient simulation model was built on MATLAB/Simulink software,and the simulation results verified the above modal analysis results and damping torque analysis results.Furthermore,the electromagnetic transient simulation results of the multi-machine two-area system demonstrate that the research conclusions can be extended to the real complex power grid scenarios with multiple machines.关键词
