中文摘要：
在研究分布式发电系统并网技术的基础上,以同时实现有功功率输出和谐波抑制为目的,设计了一种新型的DSP控制并网逆变器。该装置采用DSP对电网电流中的谐波进行检测,DSP的运行速度保证了系统具有瞬时性,消除了检测延时对系统的影响,从而实现了对谐波的瞬时检测;同时,通过DSP对检测信号进行处理,最终实现了对逆变器中IGBT的开通控制。给出了有、无谐波两种情况下的实验结果,这种新装置在将有功功率输入电网的同时,对电网中的谐波也有良好的抑制作用。研究结果证明,该装置实现了预期功能,具有较好的稳定性和实用性。
英文摘要：
To achieve the aim of energy feedback and harmonic control simultaneously,a new design of grid-connected inverter with DSP is presented on the basis of the research on grid-connected technology of distributed generation system.In order to eliminate the effect of detecting delay on the system,the device used DSP technique to measure harmonic signal,whose running speed ensured the measurement can be accomplished instantly.Meanwhile,DSP was also used to deal with the detected signals and hence can give the drive signals to IGBT of inverter further.The results under the condition of harmonic actual being or not showed that the device can input energy to the power network and achieve the harmonic control well.In conclusion, the research indicates that the device has fulfilled the anticipative function, and it will be of great reliability and practicality in the near future.
