Secondly, a simple analysis of electric power harmonics is briefly discussed — electric form.
其次，提出了一种简单的电力系统谐波分析计算的方法——电子表格。
The power system harmonic is the voltage sine wave of power system get distortion; electric locomotive power will have 0 to 50 harmonics.
电力系统的谐波是电力系统电压正弦波形产生畸变，电力机车用电会产生0次到50次谐波。
Because the electric power system harmonics have badly been polluting the electric environment, all nations are rather concerned about the harmonics and enter the research of harmonics actively.
电力系统谐波对电力系统环境造成严重污染，引起世界各国都对谐波问题给予了十分的关注和关心，并积极地对谐波进行讨论和研究。
