摘要：路灯是每个城市不可或缺的必需品，随着我国改善人民生活条件、建设小康社会及提高劳动生产水平等目标的实现，对路灯供电质量的要求也越来越高。近年来各地政府都十分重视城市光亮工作，把城市照明设施建设作为改善和美化城市环境的重要措施。让城市亮起来、美起来，已成为社会各界的共同认识。同时，路灯的供电质量也要保证。本文从路灯的系统的介绍了路灯供配电中的一些常见问题，介绍了路灯材料的选取，电缆的选择、变压器型号的选择及其它的配套设施，介绍了无功功率的补偿方法。最后还对比几种不同的节能、控制方法，选出了最优化方案。

Abstract：The street light is indispensable to each city, along with improving the living conditions in China. building a moderately prosperous society and to improve labor productivity level goals, the increasingly high requirements on the quality of street lamps powered. In recent years, local governments have attached great importance to the city light work, the construction of urban lighting as an important measure to improve and beautify the urban environment. The city lights up, America has become a common understanding of the community. At the same time, the street lamp power quality should be guaranteed. This article from the street light system introduced some common problems in the street supply and distribution, street light materials selected, the choice of cable, transformer model selection and other supporting facilities, the reactive power compensation. Finally, comparison of several different energy-saving control method elected by the optimization program.

　　　本设计详细对比和介绍了路灯照明中的无功功率和无功功率补偿方法，路灯配电系统中电力电缆的选择，以及变压器的选择和保护等几个方面。在我国目前的路灯配电系统中，较为有有优势的无功功率补偿方法为分散补偿法，即单灯补偿。在路灯照明中，还应考虑路灯照明的稳定性，即路灯应保持正常的工作状态，因此，路灯的控制系统就显得至关重要，本设计详细介绍和对比了路灯几种控制方案，选取了比较有优势的方案设计。

　　　本设计的目的，就是为了路灯照明供电系统的安全、稳定、节能和可靠。在城市化进程告诉发展的今天，本设计对路灯照明系统供配电有着一定的知道意义个参考价值。
