加合变电所三次谐波放大问题的讨论

Discussion of the Three Times Harmonic Wave Amplification Problem in Jiahe Substation

青海省电网中高耗能负荷占负荷总量的比例相当高 ,这些高耗能非线性设备对系统产生了较严重的谐波污染 ,造成电网电压波形畸变 ,对电气设备及电力用户造成一定危害。

In Qinghai power net,the high dissipative energy's load takes rather high proportion of the total load,and these load produce really serious harmonic pollution on the system,and cause distortion in the voltage,and cause damage on the power equipment and utility.The paper makes analysis and discussion of the harmonic wave problems in the Jiahe substation
