3) harmonic emission level
谐波发射水平
1.
A new method for assessing harmonic impedance and the harmonic emission level is preseented, which is based on the partial least-squares regression.
提出了一种基于偏最小二乘回归的系统谐波阻抗及用户谐波发射水平的估计方法。
2.
For controlling the harmonics in public power grid better, it is very important to assess harmonic emission level of system and customers at PCC.
为了在公共连接点合理估计系统及用户的谐波发射水平以更好地控制公用电网中的谐波污染,提出了一种基于改进Madaline神经网络的系统谐波阻抗及用户谐波发射水平的估计方法:利用在公共连接点同步测量得到的谐波电压和谐波电流信号,通过改进Madaline网络中的输入层到输出单元的连接权函数,减小了奇异值对连接权的残差平方和的影响,使其具有了良好的稳健性能,并由此映射出系统谐波阻抗,跟踪计算用户的谐波发射水平。
