AI Technical Summary

Technical Problem

In communications power systems, unequal distribution of rectifiers across three phase lines leads to current imbalances, causing circuit breakers to trip and reducing the utilization of power supply capacity due to unbalanced load currents.

Method used

A power rectification method and apparatus that dynamically adjust rectifiers on each phase line to balance input currents by reducing excess power on overloaded phases, allowing for continued power output on other phases, and utilizing a battery management system for peak clipping and capacity increase, thereby optimizing power supply utilization.

Benefits of technology

The method effectively increases power supply capacity utilization by balancing current loads across phases, reducing the need for power system reconstruction and associated costs, while ensuring reliable power delivery even during mains failures.

Abstract

This application provides a power rectification method and apparatus, to supply power to a load by using a power supply capacity gap formed by a communications power that is at an existing network site, thereby achieving a capacity increase. The method includes: obtaining a total input current of each of three phase lines; and when it is determined that a total input current of at least one of the three phase lines is greater than a total input current threshold corresponding to the at least one phase line, adjusting a rectifier connected to the at least one phase line to reduce a total input power of the at least one phase line, so that the total input current of the at least one phase line is less than or equal to the total input current threshold corresponding to the at least one phase line.
