可抑制谐波的新型节电器设计

Design of A New Type of Power-Saving Appliance with Harmonic Suppression

基于降压与谐波抑制节电技术设计了新型节电器——R&T节电器,此节电器由电压稳定调节器(RVS)及谐波抑制器(THS)两部分组成,RVS通过调节负荷端电压稳定在理想值,减少用电设备有功功率的消耗,改善电网电能过剩供给的现象,THS通过抑制负荷零线给定次的谐波量,减少畸变功率的损耗,在提高电能质量的同时达到了节电的效果。本文对设计的节电器进行了数值仿真,结果表明节电效果显著。

The design of R＆T power- saving appliance is based on the techniques of voltage- reducing and harmonic- restraining. The appliance concludes two parts. One is the Regulator for Voltage Stabilization （RVS）, and the other is the Trap for Harmonic Suppression （THS）. RVS reduces the active power of load by regulating the voltage to the ideal level. Also it reduces the surplus of energy from power net. THS reduces the distortion power by trapping the harmonic of particular frequency. It improves the quality of electric energy and saves power as well. The appliance is attested to its high power- saving efficiency by the simulation analysis.
