According to the need of household solar PV power generation, considering the impact of the inverters in parallel, the household solar PV power generation monitoring system was introduced in this paper, and also the feasibility and necessity about the PV power generation monitoring system based on DSP and CAN bus was described in detail, which realized the monitoring to multiple inverters successfully. Finally, a practical example was given. The test result show that the program runs stably and provides a simple, friendly man-machine interface,thus meeting the design requirements of the system.%根据并网型户用太阳能光伏发电的实际需求,考虑了逆变器并联可能对系统带来的影响,介绍了并网型户用太阳能光伏发电监控系统的组成、通信及监控终端软硬件的设计,深入分析了基于DSP和CAN总线进行光伏发电系统监控的可行性、必要性,成功实现了对多台逆变器进行监控,并给出了实例.经测试该方案运行稳定,提供了简洁、友好的人机交互界面,满足了系统的设计要求.
