中文摘要:针对配电网中因无功功率不平衡造成的线路低电压问题,通过潮流计算建立配电网低电压数学模型,研究了利用并联逆变器作为无功补偿装置来解决无功问题的理论依据,以单位功率因数法为控制方法。在MATLAB/Simulink上搭建了逆变器无功补偿低电压仿真模型,通过仿真实验,对比分析了接入前后的电压和电流波形的变化,仿真结果验证了该方法的可行性。

Simulation Research on Low Voltage Control of Distribution Network Based on Inverter Reactive Power Compensation
Abstract:Aiming at the low voltage problem caused by reactive power imbalance in the distribution network,the low voltage mathematical model of the distribution network is established by the power flow calculation,and the theory of using the parallel inverter as the reactive power compensation device to solve the reactive power problem is studied. According to the unit power factor method as the control method. The low-voltage simulation model of inverter reactive power compensation is built on MATLAB/Simulink. The simulation results show that the voltage and current waveforms before and after the connection are compared. The simulation results verify the feasibility of the proposed method.
