摘要
利用RT-LAB建立了一个含有风力发电机、光伏阵列、蓄电池及负荷的离网型微电源系统模型。运行时,微电网中的风机和光伏采用最大功率跟踪模式,蓄电池作为能量缓冲单元,采用电池能量控制系统控制直流母线电压的稳定并自动储存和发出功率。利用建立的模型,对外界条件变化时微电源系统运行的过渡状态进行了仿真分析。仿真结果验证了所建模型控制策略的可行性和有效性。
By use of RT-LAB,an off-grid micro-power source system model,which consists of wind generator,PV array,battery and load was designed. The wind and solar channel both have MPPT functions,battery acts as the energy buffer unit to store green energy or supply energy for the user. PCS is applied to regulate the DC bus voltage,as well as control the energy output and input. The wind solar battery power supply system model was built to simulate the syste,when the outside environment changes. The simulation result proves the feasibility and effectiveness of the model＇s control method.
