Technical field
The present invention relates to technical field of power systems, be specifically related to a kind of remote maintenance system of electric substation automation system.
Background technology
Development along with local economy; Scale of power enlarges day by day; The automatization level of electrical network is advanced by leaps and bounds, particularly develop intelligent grid after, the information of dispatch automated system collection and control is more and more; The scale of system, capacity are huge day by day, and the professional standards and the business skill of automation personnel proposed the more requirement of Gao Gengyan.
At present; In power supply administration's scope; Electric substation automation system is because Regional Distribution is wide, and the attendant often runs between each transformer station for work such as remote measurement coefficient, line name, operations staff's authority are revised, fault message is consulted, has caused the significant wastage of human and material resources.Simultaneously since the road delay with can't be in advance accurate failure judgement situation in the distance, often incur loss through delay fault handling time, be unfavorable for the safe and stable operation of electrical network.
Summary of the invention
To the deficiency that prior art exists, the object of the present invention is to provide a kind of remote maintenance system of electric substation automation system of simple in structure, easy to operate, reliable operation.
For realizing above-mentioned purpose; The invention provides following technical scheme: a kind of remote maintenance system of electric substation automation system; Comprise transformer station's complex automatic control system; Said transformer station complex automatic control system is connected with a plurality of zoness of different and can long-range fixed value modification and the remote maintenance PC work substation of remote maintenance of being positioned at; The independent setting between said a plurality of remote maintenance PC work substation, each the remote maintenance PC of transformer station work substation is given transformer station's complex automatic control system message transmission through network respectively.
Through adopting technique scheme; Can realize long-range fixed value modification and remote maintenance electric substation automation system; And utilize the power optical fiber communication network to open special-purpose communication channel, and realize Long-distance Control to monitoring system of electric substation background monitoring machine, ensure the network security of monitoring system of electric substation.
The present invention further is set to: said each remote maintenance PC work substation comprises the network switch and the network KVM device that connects PC work substation; Be pooled to the background monitoring machine of each the far-end transformer station on the network switch through network KVM device; The keyboard and mouse of each background monitoring machine is connected with network KVM device with display; Optical fiber between background monitoring machine and the remote maintenance PC work substation uses the optical communication device that an optical cable is divided into multichannel; Wherein one the road distribute to the use of remote maintenance PC work substation, optic fiber converter converts this road light signal into network signal again.Through this setting, the present invention is simple in structure, and is easy to operate, reliable operation.
Advantage of the present invention is: through to appropriate design of the present invention, compared with prior art, effectively combing the regional division of safeguarding boundary, solved the problem that the maintenance personal repeatedly runs more, alleviate maintenance workload.
Below in conjunction with Figure of description and embodiment the present invention is described further.
Description of drawings
Fig. 1 is the theory diagram of the embodiment of the invention.
