摘　　要：为提升偏远地区的供电质量,提出以分布式风光互补并网的方式,设计自动发电系统。设计风光互补并网自动发电系统结构图并研究系统的工作原理,设计可控制系统内能量的DC/DC变换器转换电路,及光控负载工作子程序中的定时与光控功能,通过逆变器的控制,令输出电压幅值与频率形成同电网电压同相、同频的正弦波电流,提升供电输出质量。以内蒙古某地点为例,分析可知该地风能与太阳能具有较好的互补性,应用研究系统后,发电量稳定,可满足用户用电需求量,且系统输出功率稳定,供电质量高,性能优越,设计合理,能够在改善电网末端偏远地区用电质量方面提供有效帮助。In order to improve the quality of power supply in remote areas,it is proposed to design automatic generation system in the way of distributed wind⁃solar complementary grid⁃connection.The structure chart of the automatic generation system with wind⁃solar energy complementary grid⁃connection is designed,the working principle of the system is researched.The DC/DC converter conversion circuit that can control the energy in the system,and the timing and light control functions in the light control load subprogram are designed.By means of controlling of the inverter,the amplitude and frequency of the output voltage can form a sine wave current with the same phase and same frequency of the grid voltage,so as to improve the quality of power output.Taking a place in Inner Mongolia as an example,the analysis results show that wind energy and solar energy in the area have well complementarity.After applying the researched system,it is found that the system has stable generating capacity,can meet the power consumption demand of users,and has stable output power,high power supply quality,excellent performance and reasonable design.It can provide effective assistance in improving the quality of electricity used in remote areas at the end of the power grid.
