Automated Switching Solar Power Grid Tie Inverter Using Embedded System
Abstract:
In this system solar power source is used to reduce the power source from the grid and this process mainly focused on switching power from one source to another during the time of low voltage from the solar power system. This system consists of embedded system, ADC, SCU, solar panel, inverter, drivers, step up transformer, switching unit, load, keypad, display, power supply, and grid in this process solar panel is used which produce DC voltage and the amount of power produced from the solar power system is monitored by the signal conditioning unit (SCU), the output of the SCU is given to the ADC. ADC is used to convert the analog signal to the digital signal. The digital signal is given to the embedded system. The embedded system is programmed to activate the driver and also display the voltage and current details through LCD. Then the DC voltage from the solar power system is converted into AC by using inverter. The inverter is controlled by the embedded system using drivers. Then the inverted voltage is boosted by using step up transformer and finally the power is supplied to the load by using switching unit. Switching unit is controlled by the embedded system by using drivers. This entire process is monitored and controlled by embedded system. In embedded system minimum and maximum limits are defined by using keypad to change the load setting. During peak sun hours between 11am-3.00pm maximum amounts of power is produced.
