  1. In accord with the state standard about harmonic. the harmonic permission value of tangqian line is calculated. some measurement data are shown and analyzed, and some main conclusion is drawed that the 7th harmonic voltages of tangqian line is near to the permission value, total harmonic voltage distortion ratio has oversteped the permission value. the 3th harmonic, the 5th harmonic, the 7th harmonic and the 9th harmonic current from tangqian line all overstep the permission, the largest 5th harmonic current ratio in tangsc reaches 44 %, the 7th harmonic and the 9th harmonic current in tang7c and tangsc is large maybe because the harmonic current is magnified. this paper studies the model of each element in tang yin substation

    根據有關公用電網諧波的國家標準，計算出湯牽線注入湯陰變電站的諧波電流允許值，從實測數據可以得出一些重要結論：湯牽線7次諧波電壓含有率的最大值接近國標中的限值，湯牽線的諧波電壓總畸變率的最大值已超標；湯牽線注入電網的3 、 5 、 7 、 9次諧波電流都超標；湯6c電容器的5次諧波電流含有率較高，最高達到44 ；湯7c和湯8c電容摘要器的7次和9次諧波電流含有率偏高，原因可能是發生了諧波電流放大現象。
  2. 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。
  3. Computation method based on fast fourier transformation ( fft ) is studied deeply, whose measurement accuracy is 0. 2s. the computing indexes involve voltage, current, power, frequency, phase, electric power, the harmonic ratio and the total harmonic distortion ( thd ) of phase voltage and phase current

    深入研究了測量精度為0 . 2s級的基於快速傅立葉變換（ fft ）的電壓、電流、功率、頻率、相位、電能等電力參數和各相電壓電流各次諧波含量、諧波含有率、諧波總畸變率的計算方法。
