Overview 1.1 Scope This is a guide for the application of digital communication for protective relaying systems and

40、 schemes, including transmitting and receiving equipment, digital channels, application principals, performance, installation, troubleshooting, testing and maintenance. Reflected in this guide are the knowledge and experience of equipment manufacturers and power utility users. This guide is not inte

41、nded to supplant specific or general instructions contained in manufacturers books nor any contractual agreements. 1.2 Purpose The primary purpose of this document is to guide the power system user in applying, installing and operating digital communication channels for the purpose of protective rel

42、aying. The guide is prepared not only for those considering digital communication relaying for the first time, but also as a reference for the experienced user.

The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause.12.1 Definitions asynchronous communications: A transmission method in which ea

44、ch data terminal equipment (DTE) transmits messages without regard for the rate at which messages are received. A Start bit is used to identify the beginning of each message byte, and a stop bit is generally used to identify the end of the message byte. A dwell time generally exists between the end

45、of one byte and the transmission of the next message byte. bidirectional line switched ring (BLSR): BLSR does not send redundant copies from ingress to egress. BLSRs switch at the line layer. The ring nodes adjacent to a failure reroute the traffic “the long way” around the ring. central-directional

46、: Clock signals supplied on different wires from a centralized clock. channel addressing: A technique used in digital teleprotection in which specific transmitters and receivers have matched addresses that are sent with data. channel delay: The sum of the communication electronics and the communicat

47、ion path delays. channel hopping: Where frame alignment is off by exactly one-channel time. co-directional: Data and timing sent in the same direction over the same two twisted pair of wires. communication configurations: See: linear drop; insert and star. contra-directional: There are always 8-wire

48、s, two pairs for clock signals, and two for data. current differential schemes: This scheme compares remotely measured values of either current samples or computed current phasors (magnitudes and angles) with locally measured time-aligned samples or phasors. The time delay associated with communicat

49、ing samples or phasor quantities must be determined by test, or automatically computed by the terminal devices to provide proper time-alignment of local and remote signals. digital data service (DDS): Also known as dataphone digital service or digital data system. A non-switched (dedicated) digital service network for data rates up to 56 000 bps. digital telephone hierarchy (T1): A digital carrier signal designed to carry speech or data at the DS1 rate, which is 1.544 Mbps. direct digital interface (DDI): A direct digital interface in a multiplexer or channel ba
