Research on the harmonic suppression based on power saver for electric distribution system

模拟配电网用户侧典型负荷组成,搭建了节电器节电行为研究平台.通过电能质量分析仪、三相可编程电源等在线监测与分析仪器,研究了配电系统节电器在阻感负荷运行工况下对负荷侧电网谐波的抑制行为.结果表明,配电系统节电器抑制电力用户侧谐波效果明显,单相电流谐波可降低2％ ～5％,波型稳定,电能质量得到有效提高.

By the simulation of distribution network user side typical load components,this paper sets the power saver energy-saving behavior research platform.Through the power quality analyzer,3-phase programmable power supplier and other online monitoring and analysis equipments,it presents the harmonic suppression behavior of the distribution system power saver in inductive load operating conditions at load side.The results show that distribution system power saver suppress the power user side harmonic effect obviously,single-phase harmonic current can be reduced by 2％ ～ 5％,the waves are stable,power quality has been effectively improved.
