The Research And Application On Smart Charging Power Supply In The FTU

Distribution automation is to improve the reliability and power quality, power supply capacity, distribution network to achieve an important means of efficiency and economic operation, but also an important basis for achieving one of smart grid. Along with raising the level of distribution automation system, FTU has become the key to distribution automation system components. FTU, as an important component of feeder automation for improving reliability of electricity supply is essential to improve the quality of power supply. Years of operation to prove:FTU long run in harsh outdoor environments, the power supply is a problem the most part, power has become a good or bad influence FTU the key to a stable and reliable operation.The topics mainly targeted at the FTU smart charging power supply used in the research and applications, including dual power supply switching, power supply and battery charging three parts, with two-way switch, power supply, three major characteristics of energy storage.This subject in the research and analysis of FTU Development of the direction of its development, based on intelligence from the FTU start charging power supply demand analysis elaborated for the use of smart charging power supply FTU basic functions and performance of the proposed charging power supply design, from both hardware and software to describe the charging power supply design implementation.This topic using LM2576 as the main power supply devices, with the PIC series of microcontrollers, power supply and battery to achieve a comprehensive intelligent management. According to on-site installation, commissioning and maintenance needs, the installation and structure of power supply design.This topic is divided into battery management software modules and dual power switching modules, focusing on communication through the I2C battery auto-activation of the module, and gives the program flow chart.Following type test and field operation test validation, charging power supply module designed in this paper the functions and performance are up to the national power industry recommended standards, and has been in business marketing application.
