TDS series pure sine wave hybrid solar inverter with MPPT 10kw
Most of the household loads are inductive loads, which will cause various power quality problems, consume household appliances, and reduce their service life. In the household off-grid system, the inverter control technology is the key. Under the structure of the household micro-grid, the off-grid inverter is taken as the research object, and the voltage fluctuation of the household off-grid DC bus and the effect of the load start-up moment on the power quality of the power supply are mainly studied. Through the voltage and current double-loop control, the power quality of the input load is improved to reduce the requirements for the DC side voltage. Through Matlab Simulink simulation verification, compare the open-loop and closed-loop waveforms of the system, and carry out harmonic analysis. The results show that the proposed dual-loop control strategy can improve the output voltage power quality of the inverter.
In order to solve the problem of power supply in areas without electricity, a rural household microgrid structure is proposed, which is suitable for remote areas that cannot be covered by large power grids.
It can solve power supply problems such as power supply reliability or poor power quality to meet the daily electricity demand of residents in remote areas.
