低压配电网电能质量治理及节能新技术方案研究

Study on New Technological Scheme of Power Quality Management and Energy Saving in Low Voltage Distribution Network

研究了低压配电网加装380 V电压等级电能质量综合治理优化装置(MEC)的新技术方案,以解决电网无功功率补偿、线路损耗、负荷高次谐波与干扰、三相电流不对称、工作电压闪变、终端电压波动等问题。

This paper studies the new technological scheme of retrofitting the low-voltage distribution network with a 380 V voltage level power quality comprehensive management optimisation device(MEC),which helps to solve the problems of grid reactive power compensation,line loss,load high harmonics and interference,three-phase current asymmetry,working voltage flicker,and terminal voltage fluctuation.
