由此得出結論： （ 1 ）調電動機端電壓調速方法簡單，一次性投資少，易於實現，對於一般的油田都適用； （ 2 ）調壓調速只有在輕負荷時，即在負荷遠未達到滿負荷時才有一定的節能效果，適用於油田普遍存在的「大馬拉小車」的情況； （ 3 ）電動機調壓調速的范圍不能太大，電壓調整的最佳范圍為額定電壓的10 %以內。To put into operation a large amount of non - linear load, make in harmony wave of rural power grids serious becoming in pollution, pass to rural local electric wire netting main in harmony analysis of wave source, put forward in order to restrain from insert rural power grids in harmony wave source voltage total in harmony wave distortion rate and the containing rate change last device number pulsating for increase of goal, increase the pulse of the current change device and install light specified value electricity active wave filter mix with passive wave filter near the harmonics source to control the wave in harmony
摘要大量非線性負荷的投運，使農村電網的諧波污染日趨嚴重，通過對農村地方電網主要諧波源的分析，最終提出了以限制接入農村電網的諧波源的電壓總諧波畸變率和各次諧波電壓含有率為目標的增加換流裝置脈動數，以及在諧波源附近裝設小額定值的電力有源濾波器配以無源濾波器的混合型電力濾波方式，以進行諧波治理。The force transducers with a nominal load of 5kn and an overload withstand capability of up to 10kn, are designed with dynamic fatigue strength for several million load alterations
