Compact Power Formats Meet Changing Conditions

Growing competition in the telecom market is exercising a downward pressure on prices for all types of network services. A high degree of cost consciousness in all network operation sectors is therefore essential. Our basic concern in the field of telecom energy (power supply, heating, ventilation and cooling) is the creation of a complete energy system designed to serve the telecom process. Rapidly changing market conditions call for energy systems capable of greater functionality and availability, faster delivery and commissioning, and better manageability, quality and service. The Telecom Energy Division of Telia AB (f. Swedish Telecom) recently completed a project entitled Compact Power Formats Meet Changing Conditions. The project task - to find answers to the issues outlined above - entailed the evaluation of a number of different power system concepts based on recent technological developments in power conversion and telecommunications. The concept which in our view best met the requirements of adaptability to rapidly changing conditions has now been described in detail, complete with purchasing specifications. The project has defined the compact power format as the concept most appropriate to our needs. Its key property is flexibility, a crucial factor in the face of changing market conditions. An exhaustive exploration of a number of critical aspects revealed major advantages for the compact power format. This paper presents an account of some of the more significant results arrived at by the project.
