Abstract
In order to accurately regulate the reactive voltage output and improve the power quality of low-voltage distribution stations,this paper carries out the research on the precise regulation and control method of reactive voltage in low-voltage distribution stations based on intelligent fusion terminal.Firstly,the intelligent fusion terminal is installed to collect real-time data from the LV distribution station area;the base state model of reactive voltage is established to fit the actual data and operation state of reactive voltage in the LV distribution station area;the relationship between adjustable reactive capacity of the inverter in the station area and inverter capacity is analyzed,and the target of reactive voltage regulation is realized by controlling the reactive power of the inverter;and the experimental results show that,after the application of this regulation method,the actual transformer output voltage and the target output voltage has a smaller degree of deviation,the maximum deviation is not more than 0.001V,has a higher precision of reactive voltage regulation in low voltage distribution area,and the advantage of regulation effect is significant.关键词
