Description
Technical field
The invention belongs to field of power, and in particular to a kind of long-range distributing monitoring system.
Background technology
In China, distribution system can be divided into high tension distribution system, intermediate distribution system and the part of low-voltage distribution system three.
Because distribution system as last link of power system region be directly facing terminal user, it whether perfect straight
The electricity consumption reliability and power quality for being related to users are connect, thus with consequence in power system.
The voltage class of China's distribution system, according to《Urban power network planning Guidance Rule》Regulation, 220kV and its more than
Voltage is transmission system, 35,63,110kV be high tension distribution system, 10,6kV be intermediate distribution system, 380,220V be low pressure
Distribution system.

Station automatic, user's automatic part.It is currently complete and distribution management automation and feeder automation are also in the starting stage
Face deeply promotes intelligent grid construction, and feeder-terminal-unit is largely used in fiber to the home power distribution station comprehensive automation construction
In, the implementation of feeder automation it is conventional have a centralized intelligence formula and distribution feeder automation pattern, both patterns just like
Lower advantage and disadvantage：
Centralized intelligence formula feeder automation pattern be uniformly controlled with a table apparatus as small main website all on-load switches come
Feeder automation is realized, i.e., all devices send relevant information toward small master station device, the logic judgment dependent on main website comes real
Existing feeder automation function.This small main website mode advantage is by a table apparatus acquisition control, and division on-load switch speed is fast.Advantage
It is uniformity and ageing good, shortcoming is exactly poor reliability, that is, place one's entire reliance upon small master station device, this device once has anything to ask
Topic, that feeder automation just can not be performed or can not correctly performed.
Distributed feeder automation pattern uses distributed communication, and its operation principle is the correlation for gathering two neighboring device
Information realizes feeder automation logic.When line failure, all feeder automation control devices are unified in loop
The on-load switch of whole piece circuit is disconnected, then since the power end toward judging combined floodgate one by one in the middle of circuit.The advantage of this mode
It is that independence is high, has the disadvantage：One is that non-fault line also can first have a power failure and restore electricity again, many to the number of operations that meets switch；
Two be to restore electricity one by one, and the time that circuit recovers is long.
