THE COLLECTION OF INFORMATION CONTROL CENTER

Abstract

Consider the option of building the last miles to telecom operators, in accordance with the requirements for the construction of the last miles of control centers in the power industry. A variant is proposed for constructing a typical network node of the last miles of the control center, taking into account all the necessary interfaces for the transmission of dispatch telephone communication channels, telemetry information transmission channels, as well as service communication channels and information exchange between electric power entities and dispatch centers. A variant of the construction and topology of the last miles of the control center, methods of reservation of channels to access nodes are described. All types and types of interfaces that are necessary to use for the organization of dispatch communication channels and the transmission of telemetric information in the dispatch centers of the regional level have been determined. The use of various types of interfaces for service purposes is described in detail. Separate types of interfaces are used for voice transmission and for dispatch communication channels with objects. The variants of using analog interfaces for transmitting telemetry information via corresponding communication channels, which are used for cent equipment with analog outputs, are described. There are several types of redundancy of communication channels to ensure uninterrupted operation of the control center and to exclude the possibility of disabling the main and backup channels at the same time when working with a particular object. The redundancy of the hardware is carried out by installing additional cards in the equipment of the nodes in the cold reserve. Power redundancy is carried out due to the presence of at least two power supply units of the equipment for connection from two different sources of the uninterruptible power supply system. There is a reserve for the optical fibers of the last miles to the access nodes, which in turn allows you to change the transport transmission line in case of failure of the current one.
