为了准确调节无功电压输出,提高低压配电台区的电力质量,本文开展基于智能融合终端的低压配电台区无功电压精准调控方法研究.首先,安装智能融合终端,实时采集低压配电台区的数据;建立无功电压基态模型,拟合低压配电台区无功电压的实际数据与运行状态;分析台区逆变器可调无功容量与逆变器容量之间的关系,通过控制逆变器无功功率,实现无功电压调控目标;实验结果表明,该调控方法应用后,变压器的实际输出电压与目标输出电压之间的偏差程度较小,最大偏差不超过0.001V,具有更高的低压配电台区无功电压调控精度,调控效果优势显著.
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.
