总畸变 meaning in Chinese
overall distortion
resultant distortion
Examples
- Among of them , the fragments and lagging chromosomes were more than the correct , the rate of the fragments was 26 . 6 % , lagging chromosomes was 32 . 8 %
其中，落后染色体和游离染色体较普遍，分别占总畸变率的32 8和26 6 。 - The detecting method of dvr is different from harmonic and reactive current detecting methods . it need detect not only total harmonic distortion but also the difference between fundamental wave component and reference value
Dvr的检测方法与谐波、无功电流的检测不同，不但需要检测出除基波分量之外的总畸变分量，还要检测出基波分量与基波基准值之差。 - 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
根据有关公用电网谐波的国家标准，计算出汤牵线注入汤阴变电站的谐波电流允许值，从实测数据可以得出一些重要结论：汤牵线7次谐波电压含有率的最大值接近国标中的限值，汤牵线的谐波电压总畸变率的最大值已超标；汤牵线注入电网的3 、 5 、 7 、 9次谐波电流都超标；汤6c电容器的5次谐波电流含有率较高，最高达到44 ；汤7c和汤8c电容摘要器的7次和9次谐波电流含有率偏高，原因可能是发生了谐波电流放大现象。 - 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
深入研究了测量精度为0 . 2s级的基于快速傅立叶变换( fft )的电压、电流、功率、频率、相位、电能等电力参数和各相电压电流各次谐波含量、谐波含有率、谐波总畸变率的计算方法。
