缅甸蒙育瓦莱比塘铜矿项目的供配电特点分析

Analysis on the Characteristics of Power Supply and Distribution of Myanmar Monyuwa Letpadaung Copper Project

针对缅甸莱比塘铜矿项目占地面积大、供电负荷大且分散、控制要求高等供配电特点,介绍了该项目供配电系统配置情况。该项目通过设置1座230/33 kV总降压变电站、5座33/10 kV变电站、10座10 kV配电站,及数十个10/0.4 kV低压变电所,提高主供电网络电压等级,保证了良好的电能质量,减少电压降。同时,该项目利用线路的架空布设,以及电力综合自动化系统、太阳能照明设施等的应用,保障了该项目的供配电系统安全可靠、环保节能。

According to the characteristics of power supply and distribution of Myanmar Monyuwa Letpadaung Copper Project,such as large floor area,large and distributed power supply load and high control requirement,the paper introduces the configuration of power supply and distribution system of the project.The project improves the voltage level of the main power supply network,ensures good power quality and reduces voltage drop by establishing one 230/33 kV main step-down substation,five 33/10 kV substations,ten 10 kV power distribution stations and dozens of 10/0.4 kV low-voltage substations.Meanwhile,the project ensures the safety,reliability,environmental protection and energy conservation of the power supply and distribution system by using the overhead layout of the line,as well as the application of integrated power automation system and solar lighting facilities.
