摘要
以往的采集终端备电系统虽然能在电网停电的状态下持续供电,但其电能转化率低,造成了很大的资源浪费。在上述背景下,设计基于正弦脉宽调制(Sinusoidal Pulse Width Modulation,SPWM)技术的采集终端备电系统。在硬件设计上,设计了备电光伏板和采集电源信息继电器;在软件设计上,利用SPWM调制技术转化率高、低成本、高效能的特点设计了系统的逆变输出模块,结合发电模块和蓄电模块,完成了采集终端备电系统的设计。通过系统实验表明,设计的备电系统电能转化率远高于以往的备电系统,电能转化率更高。
Although the former acquisition terminal standby power system can continue to supply power in the state of power grid outage,its power conversion rate is low,resulting in a great waste of resources.Under the above background,the acquisition terminal standby power system based on Sinusoidal Pulse Width Modulation(SPWM)modulation technology is designed.In terms of hardware design,a standby photovoltaic board and a relay for collecting power information are designed.In terms of software design,the inverter output module of the system is designed based on the technical characteristics of SPWM modulation technology,such as high conversion rate,low cost and high efficiency.Combined with the power generation module and the power storage module,the design of the acquisition terminal power reserve system is completed.The system experiment shows that the power conversion rate of the designed standby power system is much higher than that of the previous standby power system,and the power conversion rate is higher.
