Abstract
With the widespread application of new energy sources in the distribution network,the harmonic problem they generate is becoming increasingly serious,which has a negative impact on the performance of communication power sources in the distribution network.This article proposes research on reactive power compensation and harmonic suppression methods for communication power sources in new energy distribution networks.By optimizing the reactive power compensation capacity of distribution network communication power supply,reactive power loss can be effectively reduced.Then select a series filtering inductor and design an efficient harmonic suppression device.Reasonably configure these devices to effectively filter out the harmonics generated by the power supply and reduce the harmonic content.Finally,the proposed method is validated through comparative experiments.The experimental results show that the harmonic content of each experimental point is successfully controlled below 20%using the proposed method,which is superior to the comparative method.This proves that the method has great potential and obvious advantages in practical applications,not only effectively improving power supply quality,but also has broad practical application value.
