| 摘要: |
| 太阳能光伏发电系统由太阳能电池阵列、控制器、逆变器、蓄电池组等部件构成。提出以新型单片机PIC16C 73为核心的太阳能逆变控制器,其硬件由单片机、电压采集、逆变、电压反馈、过电流保护、显示等单元组成,并对各单元功能进行了说明。控制器软件采用模块化结构,使用汇编语言编程,软件包括脉冲宽度调制(PWM)、采样比较、数字滤波、软启动、显示报警等模块。控制器采用掉电保护、指令冗余、软件陷阱、数字滤波等方法,以提高控制器的稳定性。通过搭建的实验线路测试结果表明,所研制的控制器各项指标符合设计要求。 |

| Abstract: |
| Solar photovoltaic system consists of solar cell array,controller,inverter and storage battery.A solar inversion controller based on singlechip PIC16C 73 is proposed for solar power supply system.Its hardware consists of function units,such as singlechip,voltage sampling,inverter,voltage feedback,overcurrent protection and display,which are explained in detail.Programming with assemble language,its software consists of structured modules,such as PWM(Pulse Width Modulation) control,sampling comparison,digital filter,delayed start,display and alarm,etc..Power failure protection,instruction redundancy,software trap and digital filter are used to improve the stability of the controller.Experiment results show that the controller meets design requirements. |
