摘　　要：针对虚拟同步机控制技术中阻尼系数的引入无法同时抑制输出有功的暂态震荡和稳态偏差的问题,提出了一种基于阻尼功率调整的虚拟同步机有功功率控制方法。首先分析了常规虚拟同步机有功功率控制存在的主要问题,然后在常规控制策略中增加了一个比例积分控制器,用于调整阻尼功率,使暂态阻尼功率不为零,实现有功功率震荡和超调的抑制,同时使稳态时阻尼功率为零,实现有功功率稳态偏差抑制。Matlab/Simulink仿真结果验证了所提方法的有效性。The transient oscillation and steady-state deviation of output active power cannot be suppressed at the same time by introducing damping coefficients into the control technology of virtual synchronous generator.Therefore,the paper proposes an active power control method for the virtual synchronous generator based on damping power adjustment.Firstly,the main problems in the conventional active power control method for the virtual synchronous generator are analyzed.Then a proportional and integral controller is added to the conventional control strategy to adjust the damping power,suppressing the oscillation and overshoot of the active power,ensuring the damping power to be zero in the steady state,and eliminating the steady-state deviation of the active power.MATLAB/Simulink simulation results verify the effectiveness of the proposed method.
