Distribution Automation requirements for communication
Cnc machining SCADA system with the same dispatch,
distribution automation system also needs an effective communication network,
and he has his own characteristics: the number of terminals very much. System
has a large distribution network by opening and closing, power distribution
transformers, circuit breakers column to monitor these devices requires a
number of FTU and TTU, while the FTU with the power distribution equipment
installation, wide geographical distribution, communication nodes scattered.
Distribution automation system size, complexity and automation level of
the decision of the communication system should meet the following
requirements:
(1)
Reliability:
Communications equipment distribution network systems have many exposed
outdoors, bad environment, so must be able to withstand heat, cold, sun, rain,
snow, hail and lightning and other natural attacks.Cnc machining Meanwhile, try to avoid all
kinds of electromagnetic interference, to ensure long-term stable and reliable
work, and asked when the line power failure, communication system can still
work properly
(2)
economy:
Taking into account the overall economic power distribution system, communication system, investment should not
be too large, and strive to make full use of the existing main network
communication resources, for the Lord, the overall distribution network
planning, avoid duplication of investment.
(3)
addressing large:
Communication system not only to consider the present and future data
needs, but also consider the upgrade requirements.
(4) two-way communication:
Distribution network automation to achieve the telemetry, remote, remote
control, you must request a two-way communication capabilities.
(5)
easy operation and maintenance.
According to the above requirements,Cnc machining along with fiber prices down, at
present, optical fiber communication systems are widely used in electric power.
