Description
Technical field
A kind of transformer substation monitoring system, belongs to electrical substation monitoring technical field, relates generally to a kind of intelligence based on ARM and becomes
Power station real-time monitoring system.
Background technology
High speed development and the continuous progress of science and technology with society, power system are lived as national product is related to
Important step, develop towards intelligentized direction.As one of most important electrical equipment in power system, transformer station
Intelligence degree directly determines the development of intelligent electric Force system, with important Research Significance.Current China researcher
Research to intelligent substation is made that substantial amounts of work, has put into a huge sum of money, and generate certain achievement in research.So
And, the temperature and relay protection system monitoring process low-response of current transformer station, it is impossible to accomplish monitoring in real time, and radiating effect
It is bad, it is impossible to meet the daily demand of people.
The content of the invention
In order to solve the above problems, the invention discloses a kind of intelligent substation real-time monitoring system based on ARM, by nothing
Line sensing network is combined together with becoming electrical equipment, is realized and is carried out wireless real-time monitoring to the parameter index for becoming electrical equipment, monitors precision
Height, monitor speed is fast, it is easy to accomplish.
The object of the present invention is achieved like this：
A kind of intelligent substation real-time monitoring system based on ARM, including temperature monitoring system, relay protection system, master control system
System, wireless sensing system and cooling system, the output end difference of the temperature monitoring system, relay protection system and cooling system
Established a connection with the input of master control system, the output end of master control system and the input of wireless sensing system set up two-way
Data communication annexation.
Further, the system for detecting temperature includes Temperature sampler, the AD processing units established a connection successively
With precision alignment unit, the precision alignment unit output end establishes a connection with master control system.
Further, the Temperature sampler uses thermocouple temperature sensor, 0-1024 DEG C of acquisition range.
Further, the relay protection system includes protection device and the electric mutual inductor being sequentially connected, the electronics
Transformer direct measurement capacitance current, realizes the monitoring to high tension voltage.
Further, the relay protection system is that current comparison pilot protection, breaker fail protection and reclosing are protected
Shield.
Further, the current differential protection is widely used in becoming because its outstanding selectivity and sensitivity
In the protection of the important electricals such as depressor, bus, main protection is typically used as.If not considering point that transmission line of electricity is formed over the ground
Cloth electric capacity, then from can macroscopically be regarded as an electrical node.It can be seen from Kirchhoff's current law (KCL), if circuit is normally transported
External fault only occurs for row, then flows into the current phasor of the node and be zero, i.e.,：
=0
In formula,To flow into transmission line of electricityThe current vector of side.
When internal fault occurs for protected circuit, fault branch flows into the fault current of busWill destruction of balance,
Now：
=
Current phasor and be zero that this electric current is formed in differential protection relay, relay is not acted.The protected mode
Quick-action is strong, almost can reach without time limit excision, and developing rapidly for fiber optic communication causes level linked differential protection in long range
High pressure, be also widely used in the route protection of super-pressure.
Further, when system jam, the protective relaying device of faulty equipment sends trip command, and breaker
During generation tripping, the breaker actuation separation failure of neighbouring device, such protection is referred to as breaker fail protection.It is according to guarantor
The electric current of the action message of protection unit and the breaker not worked be according to differentiate breaker whether failure.The protected mode can
All breakers associated there in quick excision station, protect electric power netting safe running, minimally limit power failure range.It is disconnected
Once road device failure protection trigger action, the then breaker for assembling all branch road electrical equipments on the transmission of electricity bus of the protection all will
It is removed, its operation circuit links together, therefore, may be along with serious accident once occurring malfunction, this is also just dashing forward
The significance level of its reliability is gone out.In order to avoid the generation of accident, breaker fail protection action, two conditions lack one not
Can：That is not involution after the action of fault element protection exit；Another is that in by protection domain, bus is checked using decision element
The phase current of upper each bar branch road whether there is to judge whether oneself is eliminated failure, if not eliminating, protection act.
Further, from the passing fact through examining, failure is mostly occurred on transmission line of electricity, and wherein overhead transmission line is particularly occupied
It is many, but this kind of failure of the overwhelming majority is not permanent, is all often with unexpected generation, in temporary fault shape
State, for example the wind howled can make power transmission line short for contact, can recover automatically when wind is flat：And for example the electric meat of Thunderstorm Weather is thunderous to draw
The insulator risen is ingeniously sparkled；And birds and branch are also so that the uncertain factor that power transmission line breaks down.But send class failure due to
Its contingency with it is temporary, need to only overlap the rapid cut-out of Fujian protection, wait after the high skilful complete daughter-in-law of electric arc goes out, re-close knife
Fujian, circuit just can normal power supply, in the absence of any potential safety hazard.It is such as this through just recoverable failure is temporary after a while
When property failure.Assembling overlap explain protection can W avoid unnecessary trouble, fast recovery of power supply, this reliability to improving power supply
It is clearly favourable.For from principle, it can be explained between coincidence by the manually operated conjunction of the office worker that powers, but automatics is fast and reliable,
It can avoid having a power failure for a long time, and manually operate the problem of high-pressure system that may be brought is unstable.Therefore it is automatic in power system
It is widely adopted between coincidence.Double power-supply system paired running stability can be significantly improved between automatic reclosing.The investment of itself is low,
Reliable operation.Therefore, automatic reclosing is explained protection and is just particularly important.As long as China's code regulation is disconnected in 10kV and following installing
On the overhead transmission line or cable of road device, automatic reclosing will be installed and explain device tw.But, everything has dual character, if failure
Point happens is that permanent fault, again close between after, system can because send be continually subjected in shorter time interval it is short twice
Road rush of current and produce vibration even step-out, cause system parallel off accident further to expand.According to the difference of application environment, from
Device has different differentiations between dynamic coincidence, and such as single-phase automatic reclosing is explained, blue phase automatic reclosing explains team and automatic reclosing is explained.
Further, the master control system includes the first master control system and the second master control system, first master control system
The first peripheral circuit being connected including the first main control chip and with the first main control chip, the second master control system includes the second master control
