摘要
One of the chief characteristics of the construction of a digital communication network with service integration based on a new-generation automatic exchange is the wide use of remote substations or concentrators. A remote means of guaranteed electrical power supply to a remote substation or concentrator along free pairs of lines can be constructed. A power supply (GEPS) may be organized in two ways: remote on the reference exchange side from a centralized power supply point (CPGEPS) or from intermediate power supply points (IPGEPS). The possible options for constructing a system for supplying electric power to a substation are examined. Compared with traditional systems, systems with a remote-delivery GEPS have lower capital costs and operating expenses and have high reliability and a much lower volume of electric power supply equipment.
