Abstract

The desire to reduce electrical loading by using energy efficient lighting has resulted in a high level of interest in replacing conventional incandescent lamp with Compact Fluorescent Lamps and LED lamps. However, their high harmonic content was always a problem for the power quality of the power system networks, especially the ones with a considerable share of nonlinear loads. The problem of harmonics cannot be neglected in cases of installations with high lighting load. This paper presents an analysis of harmonics in a network where lighting is one of the main loads. CFLs and LED lamps with electronic gear are characterized by extremely distorted current, with high total current harmonic distortions. Hence they cause a significant voltage distortion in electrical installations. The network is simulated using the impedance network model, in PSCAD®/EMTDC™ software. A comparative analysis is performed on the power quality, maximum loading and economics of CFL lamps and LED lamps.

节能灯和LED灯的比较-谐波干扰，经济性(成本和电能质量)和电力系统的最大可能负荷

通过使用节能照明来减少电力负荷的愿望导致了用紧凑型荧光灯和LED灯取代传统白炽灯的高度兴趣。然而，它们的高谐波含量一直困扰着电网的电能质量，特别是在非线性负荷占相当大份额的电网中。在高照明负荷的情况下，谐波问题是不容忽视的。本文分析了以照明为主要负荷的电网中的谐波。带电子齿轮的节能灯和LED灯的特点是电流畸变严重，总电流谐波畸变高。因此，它们在电气装置中引起显著的电压畸变。在PSCAD®/EMTDC™软件中使用阻抗网络模型对网络进行模拟。比较分析了节能灯和LED灯的电能质量、最大负载和经济性。
