摘要:
 摘要:根据三相光伏并网逆变器dq旋转坐标系下数学模型,推导了三相光伏逆变器偷出有功功率、无功功率和电网电压、逆变器输出电压、电流之间关系。提出基于空间矢量调制的无差拍功率控制策略,实现三相光伏并网逆器有功功率、无功功率的快速跟踪和解耦控制,输出三相电流波形
正弦度好,有功功率和无功功率波动小,且输出频率固定,有利于滤波电感的设计。在一台12 kW样机上进行了实验验证,实验结果表明三相光伏并网逆变器具有良好的静、动态特性,无差拍功率控制策略正确可行。
Abstract:
 Abstract:According to the mathematical model of three-phase photovoltaic grid-connected inverters in dq rotating reference frame,the relationships were derived between the active power and reactive power,grid voltages,the inverter output voltages and currents. The dead beat power control strategy based on space vector modulation(SV M ) was proposed , which achieves fast tracking and decoupling control of the active and reactive power, the output currents are sinusoidal,the ripple of the power is small. The output frequency was fixed,which is helpful to design filter inductance. The experiments were carried out in the 12 kW prototype,the experimental results show that the three-phase grid connected inverter has a good static and dynamic performance,deadbeat power control strategy is correct and feasible.
