In this paper, we present a summary of lightning protection measures aimed at securing a more reliable power supply for a telecom building. Based on an analysis of the entry paths of lightning surges into telecom building, we implemented lightning protection measures for the power receiving facilities by strengthening the equipment's tolerance to overvoltage surges. This was achieved by using a multistage...
Telecommunication service providers are adding renewable power sources for powering evermore of their telecommunication sites, such as central offices and cell towers. Such options bring benefits in operating costs and increased reliability especially in remote sites. However, it also introduces a host of new, often disparate equipment to the network that the service providers must maintain and replace...
It is discussed that the changing of parameters in the battery pack model affects the control accuracy and dynamic response of the charging system, through establishing the peak current small signal model of the full-bridge converter and load battery packs' model of the charging system. Moreover, the disadvantages of fixed parameters PID control are put forward. An online identification method is...
