| 摘 要： | 指出了在新能源供电系统中,三相并网逆变器将直流电能通过逆变器转换成交流电能,并入到公共电网中,供其他用户使用。为保证电网运行安全、稳定,对并网的电流和电压谐波含量、频率的偏差都有着严格的要求和规定,需要满足谐波含量较低和功率因数为1。研究了并网逆变器电流跟踪控制策略及SVPWM的调制方式,在PSIM软件中进行了系统建模与仿真调试,仿真结果表明:实现了逆变器输出电流和电网电压拥有相同的频率和相同的相位,谐波含量较低和功率因数为1,证明了并网逆变器控制方法的正确性。

| Abstract: | In the new energy power supply system,the energy of DC changed into AC through the three-phase inverter for grid connected,which is incorporated into the public power grid for other users.In order to ensure the safety and stability of power grid operation,there are strict requirements and regulations for the deviation of harmonic content and frequency of current and voltage in grid connection,and the requirements of low harmonic content and power factor of 1 need to be satisfied.The control strategy of grid connected inverter and SVPWM modulation mode of is studied.The simulation results show that output current and grid voltage of the inverter have the same frequency and phase;,the harmonic content is low and the power factor is 1.It is proved that the control method of grid connected inverter is correct. |
