铁塔运营模式下的通用直流供电系统设计

Design of General DC Power Supply System in the Operation Mode of Iron Tower

随着移动信息技术产业的迅速发展,移动铁塔供电系统的可靠性要求越来越高。目前各大运营商的高压直流电源的电压等级不同,严重阻碍了铁塔高压直流供电系统共建共享的实现。为此,文中提出铁塔运营模式下的通用直流供电系统,该供电系统是在现有供电系统的基础上,使用双向直流/直流转换器实现各运营商的直流供电系统间的互相备份和兼容。最后,文中对通用直流供电系统的可靠性进行数值分析,其可以有效地提高系统的可靠性。

With the rapid development of the mobile information technology industry,the reliability of the power supply system of the mobile tower is becoming more and more demanding.At present,the voltage levels of the HVDC power supply of the major operators are different,which seriously hinder the realization of the co-construction and sharing of the HVDC power supply system.Therefore,a universal DC power supply system under the tower operation mode was put forward in this paper.Based on the existing power supply system,and used the two-way DC/DC converter,the power supply system realized the mutual backup and compatibility between the DC power supply systems of the operators.Finally,the reliability performance of the universal DC power supply system was numerically analyzed,and the universal DC power supply system can effectively improve the reliability of the system.
