With the adoption of the utility model, networks can be spread to distant ends on a converting station integrated automatic system through the network KVM technology so as to realize remote maintenance of the remote constant value modification and the integrated automatic system; and in addition, special communications channels are arranged by using electric power optical fiber communication networks so as to realize the remote control for the background monitoring apparatuses of a converting station monitoring system and ensure the network security of the converting station monitoring system.
Description
Technical field
The utility model relates to technical field of power systems, is specifically related to a kind ofly utilize long-range KVM technology to realize protective device in the power system transformer substation is carried out long-range fixed value modification and automated system background monitoring machine carried out the system of remote maintenance.
Background technology
For many years, relay protection of power system definite value change work takes corresponding primary equipment to have a power failure always, and the protection professional is in the mode of transformer station's field modification, and usually making itself only needs the work of a few minutes but to expend several hrs.The mode of the change protection definite value that has a power failure needs to consume bigger manpower and materials cost on the one hand, has increased operating risk; Greatly reduce power supply reliability on the other hand.
For reducing the relaying protection O﹠M cost, improving power supply reliability; be necessary traditional scene, the pattern of revising definite value that has a power failure are innovated improvement; make full use of the online modification function that microcomputer protecting device and comprehensive automation system of transformer substation possess, realize the long-range fixed value modification of relaying protection.
In addition, in power supply administration's scope, automated system is because unit type is many, Regional Distribution is wide, the attendant often runs between each transformer station/power 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 because the road delay and 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
The purpose of this utility model is the problem that solves above-mentioned two aspects, on comprehensive automation system of transformer substation, network is extended to far-end by network KVM technology, to realize long-range fixed value modification and complex automatic system remote maintenance, and utilize the power optical fiber communication network to open the Long-distance Control of special-purpose communication channel realization to monitoring system of electric substation background monitoring machine, guarantee the network security of monitoring system of electric substation.
The purpose of this utility model is achieved through the following technical solutions.
Long-range fixed value modification of transforming plant protecting device and remote maintenance system; this system comprises the PC work station that is used for remote maintenance; the network switch that connects the PC work station; be pooled to each far-end transformer station background monitoring machine on the network switch by network KVM device; the keyboard and mouse of each transformer station's background monitoring machine is connected with network KVM device with display; optical fiber between far-end transformer station background monitoring machine and the remote maintenance PC work station uses the optical communication device that an optical cable is divided into multichannel; wherein one the road distribute to the remote maintenance system use, optic fiber converter is converted to network signal with this road light signal again.
The utility model utilize network with the function expansion of KVM to optional position that network can reach; Utilize electric substation automation system background monitoring machine to realize to the protective device fixed value modification; Utilize electric power special optic fibre constructing system dedicated network.Not only saved production cost, also realized protective device remote online fixed value modification, reduced, improved power supply reliability, increased user satisfaction customer outage hours.Reduce grid switching operation simultaneously, greatly reduced operations staff's misoperation risk.System builds up the back attendant can in time diagnose and instruct processing to the problem of protective device in service, automated system existence in the distance, improves protective device and automated system availability factor; Can improve supervisory control system fault location accuracy, carry out and eliminate defective work targetedly, improve the monitoring system of electric substation operation and maintenance level, help power network safety operation.
Further set forth content of the present utility model below in conjunction with Figure of description and embodiment.
Description of drawings
Fig. 1 is the utility model network topological diagram.
Embodiment
As shown in Figure 1, at machine room a PC work station that is used for remote maintenance is installed, the keyboard and mouse of each far-end transformer station background monitoring machine is connected with network KVM device with display, the remote maintenance network of each far-end transformer station background monitoring machine is pooled on the network switch, and remote maintenance PC work station also is connected with the network switch.Optical fiber between far-end transformer station background monitoring machine and the remote maintenance PC work station uses the optical communication device that an optical cable is divided into multichannel; wherein one the road distribute to the remote maintenance system use; optic fiber converter is converted to network signal with this road light signal again, constitutes a protection definite value remotely modifying and an electric substation automation system background monitoring machine remote maintenance network that is based upon on the dedicated network basis that the power system communication special optical cable makes up.KVM device collection keyboard, display, mouse are one, and one group of KVM device can connect many equipment.The operator can and control many computers or server by the visit of KVM operating desk.
In the time of need carrying out long-range fixed value modification and automation background monitoring machine remote maintenance to a certain transformer station, only need on remote maintenance PC work station, to log on certain transformer station's background monitoring machine by the IE browser, can be in machine room be controlled far-end transformer station automated system background monitoring machine, utilize the definite value management function of background monitoring machine to realize long-range fixed value modification and comprehensive automation system of transformer substation remote maintenance functions.
