摘要
本文提出了一种由双PWM变换器构成的新型轴带发电系统控制策略,其整流侧将轴带发电机发出的电压、频率变化的交流电变换为直流电;逆变侧采用虚拟同步发电机控制策略,使逆变器具有与柴油发电机相似的输出下垂特性和电气、机械特性,保证该轴带发电系统能与常规的柴油发电机组长期稳定并联运行。在MATLAB/Simulink环境下搭建了该新型轴带发电系统的仿真模型,对其与柴油发电机组的并联运行进行了模拟,对模型中转动惯量对系统的影响进行了分析,验证了该控制策略的可行性。
A new control strategy of marine shaft-driven generator system with dual PWM converter is introduced in this paper. The rectifier side changes varying AC to DC, and the inverter side adopts the virtual synchronous generator based on control algorithm to achieve the droop characteristics and electrical-mechanical characteristics, which are similar with the diesel generator system. This will ensure the marine shaft-driven generator system can operate with the diesel generator system in parallel for a long time. The simulation model of the new shaft-driven generator system is built by using MATLAB/Simulink and the parallel operation with the diesel generator system is simulated, the influence of the rotational inertia in the model is analyzed, and the control strategy is verified
