| 摘 要： | 从节能减排的角度出发,设计了一种基于SPWM技术的光伏并网发电模拟装置,DC/AC逆变可以有效地进行直流至交流的转换。系统通过单片机编程的方式实现了最大功率点控制、频率和相位的跟踪。同时单片机还能通过编程方式实现PWM脉冲宽度调制。本系统最大的特点是用模拟的方式简明地介绍了整个光伏并网发电系统。

| Abstract: | On the standpoint of energy conservation and emission reduction,one device simulating the photovoltaic grid-connected generation system based on SPWM was designed in the paper.And DC/AC inverter could transduce efficiently direct current to alternating current.The MCU(micro-control-unit),in this system could achieve the control method for maximum-power-point and tracking for frequency and phase.Moreover,the MCU could implement PWM(plus-width modulating) through programming.The system showed clearly the whole photovoltaic grid-connected generation system using simulated methods and ways. |
