Abstract
The invention discloses comprehensive protection management machine of an intelligent substation spacer layer. The comprehensive protection management machine comprises a host computer and an optical fiber transceiver, wherein the optical fiber transceiver is connected with the computer by using communication lines; the optical fiber transceiver is in signal connection with an intelligent substation spacer-layer optical network by using optical fibers; the host computer has the functions of low frequency and low cycle protection, overload intertripping, backup power supply switchover, fault wave recording, network analysis and near backup protection, wherein the hear backup protection function comprises functions of selecting equipment as backup protection, providing a backup protection function which can execute more than two sets of protection, printing a protection constant value can be printed and switching a constant value region; and the functions of overcurrent protection, distance protection, light equation protection, soft pressing plates and control characters are provided. At present, the function of realizing the comprehensive protection and management at the intelligent substation spacer layer is adopted. The comprehensive protection management machine not only realizes the function of a safety automatic device, but also realizes the fault wave recording and network analysis, and the functions of backup protection of all secondary devices in the substation are also realized.
Description
Technical field
The present invention relates to a kind of automatic protection equipment, especially a kind of intelligent substation wall integrated protection supervisor.
Background technology
Original consideration realizes that on the transformer station backstage idea of functions such as low all underfrequency protections, automatic safety device receives great restriction in practical application.Because transformer station's backstage station level network using Ethernet electricity oral instructions are defeated; Corresponding with it 61850 station level stipulations; These stipulations are used for background monitoring and can meet the demands; If but be used for realizing protecting calculated example like the slippage locking of low week protection then message transmission rate is slower, can't meet the demands.
Intelligent substation wall network circulating nearly all exchange of information relevant and control signal in the intelligent substation with primary equipment.Existing consideration utilizes the information development one cover integrated protection management system of transmitting on the fiber optic network at the intelligent substation wall.This system can integrated low all underfrequency protections, overload join cut, the backup protection function of failure wave-recording, network analysis and all wall protective devices.
If increase the integrated protection management system at wall, then can well address the above problem.Integrated low all underfrequency protections, overload couplet are cut multiple functions such as protection, prepared auto restart protection, failure wave-recording, network analyzer on a computer as the wall main frame.The more important thing is the various information that to use this system to gather the intelligent substation wall easily, realize the nearly backup protection of the protection of all single cover microcomputers in the intelligent substation.After adopting the backup protection function of intelligent substation wall integrated protection management system; In transformer station, change definite value on single cover Microcomputer Protection and general disappearing just can be avoided the power failure of primary equipment when lacking work, with integrated protection management system realization temporary protection function.Treat to come in switching after hours on single cover microcomputer protecting device, realize the single cover relaying protection maintenance work that does not have a power failure.
Therefore, designing a kind of intelligent substation wall integrated protection supervisor, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved by this invention provides a kind of intelligent substation wall integrated protection supervisor.
The technical scheme that the present invention solves its technical problem is:
Intelligent substation wall integrated protection supervisor (1); Form by main frame and fiber optical transceiver; It is characterized in that be connected with connection between fiber optical transceiver and the computer, fiber optical transceiver utilizes optical fiber to be connected with intelligent substation wall fiber optic network signal; Described main frame possess the low week protection of low frequency, overload join cut, automatic closing, failure wave-recording, network analysis and nearly backup protection function; Wherein near backup protection function comprises:
can select the equipment protected in support;
can carry out the backup protection function of the above protection of two covers simultaneously;
can print the protection definite value;
can switch the definite value district;
has overcurrent protection, distance protection, equation of light protection, soft pressing plate, control word function.
Be employed in the intelligent substation wall at present and realize the function of integrated protection management.The function that this integrated management function is not singly realized automatic safety device can also realize failure wave-recording, network analysis, the more important thing is the function that can realize the backup protection of all secondary devices in the transformer station.With two coverization configurations that can realize all single cover Microcomputer Protections in the transformer station once the cover microcomputer.All resource-sharings, this also is advantage place of intelligent substation.
Description of drawings
Fig. 1 is a principle calcspar of the present invention.
Embodiment
As shown in the figure; Intelligent substation wall integrated protection supervisor 1; Be made up of main frame and fiber optical transceiver, be connected with connection between fiber optical transceiver and the computer, fiber optical transceiver utilizes optical fiber to be connected with intelligent substation wall fiber optic network 2 signals; Described main frame possess the low week protection of low frequency, overload join cut, automatic closing, failure wave-recording, network analysis and nearly backup protection function; Wherein near backup protection function comprises:
can select the equipment protected in support;
can carry out the backup protection function of the above protection of two covers simultaneously;
can print the protection definite value;
can switch the definite value district;
has overcurrent protection, distance protection, equation of light protection, soft pressing plate, control word function.
