市政LED路灯谐波治理

Harmonic Control of Municipal LED Street Lamp

通过分析LED灯具的电路结构,阐述LED灯具产生谐波的原因,使用PSIM对LED灯具的驱动电路进行仿真模拟,得到LED灯具的驱动电路电流波形,分析计算了使用LED灯具产生的谐波,结合实际的测试数据,介绍了LED灯具大规模使用产生的谐波治理方法,以解决市政路灯等大规模LED使用时对电网的危害。

By analyzing the circuit structure of LED lamps,the cause of harmonic generation of LED lamps is described.PSIM is used to simulate the driving circuit of LED lamp,and the current waveform of the driving circuit of LED lamp is obtained.The harmonics produced by using LED lamps are analyzed and calculated.Combining with the actual test data,the method of harmonics control generated by large-scale use of LED lamps is introduced,which can solve the municipal street lights and other large-scale LED use of the harm to the power grid.
