Base station external power grid capacity increasing and voltage stabilizing system and method

Abstract

The invention discloses a base station external power grid capacity increasing and voltage stabilizing system and method. A power grid end, a power supply line and a base station end are connected insequence. The system comprises a structure I or a structure II; according to the first structure, a boosting module is connected between the power grid end and the power supply line in series; and according to the second structure, a boost module is connected in series between the power grid end and the power supply line, and a buck module is connected in series between the base station end and the power supply line. The boost module comprises one or more boost unit for outputting different gear voltages and one or more change-over switch, and the change-over switch controls the correspondingboost unit to be connected with or not connected with the power supply line. Voltage stabilization and capacity increase transformation is carried out without changing an existing external power gridline structure, the structure 1 ensures the working stability of base station equipment, and the power supply efficiency is improved; and the second structure can perform capacity increasing and voltage stabilizing transformation on an existing power supply network. The boost units with different voltage gears can be switched for boosting according to the amplitude change of the base station load,so that the base station load is prevented from overvoltage damage.

Description

technical field [0001] The invention relates to the technical field of a power grid outside a base station, in particular to a system and method for increasing capacity and stabilizing a power grid outside a base station. Background technique [0002] During the long-term operation of communication base stations, due to the continuous increase in power load, the co-construction and sharing of multi-operator services, mobile communication from 2G, 3G, 4G to 5G multi-network co-location, and optical transmission networks from SDH, MSTP, PTN to F5G , and the rise of edge computing services have increased the load on the power grid outside the base station, reducing the quality and reliability of the power supply of the base station. The current situation of the introduction of mains power outside the communication base station includes: due to the low initial load and high cost, the proportion of 10KV dedicated transformers in the equipment station is relatively low; due to the...

Problems solved by technology

The current situation of the introduction of mains power outside the communication base station includes: due to the low initial load and high cost, the proportion of 10KV dedicated transformers in the equipment station is relatively low; due to the special needs of the location of the equipment room, the power supply lines of some base stations are too long >1KM); unattended base stations use a large number of aluminum alloy cables for line anti-theft, and there is a problem of copper-aluminum conversion; the power supply line of the communication room and a large number of other power lines coexist in the same pole and pipe trench, and the line maintenance is relatively troublesome
