Abstract
The utility model discloses an overcome current technical defect, provide a direct current transmission controlling means switched systems, including the protection host computer, with the main control system of protecting the host computer to be connected, the main control system is provided with the control unit, automatic unit and the switch unit kept watch on, the switch unit is provided with automatic switch -over unit and manual switch unit, and it is automatic keeps watch on the unit and be connected to automatic switch -over unit and manual switch unit respectively, the control unit is connected to automatic keep watch on unit and switch unit. This system takes all factors into consideration the influence of each other between two systems of direct current control system at the switching in -process, can carry out the automatic switch -over or change manual switching into different modes such as two sets of system's simultaneous faultss, priority troubles.
Description
Technical field
The utility model relates to direct current transportation control technology field, particularly relates to a kind of direct current transportation control device switched system.
Technical background
Control system is indispensable for the operation of DC transmission system, its running status has (active) on duty, (standby) for subsequent use, service (service) and test (test) four kinds, normal when running two cover DC control system be that a redundant fashion for subsequent use on duty runs, system possesses from the function monitored and automatically switch.System is divided into minor failure, catastrophe failure, emergency from function for monitoring according to the influence degree of control system fault to systemic-function monitored.The fault of control system automatic switchover logic to different brackets makes different systematic evaluation strategies.
DC transmission system protected host action outlet exports through main control system; and general protection act outlet first carries out control system systematic evaluation; if after control system is switched to back-up system, back-up system does not receive protection act instruction, then locking direct current signal will disappear automatically.
Current direct current control and protection system switch logic checks and accepts, verification method mostly is analog hardware fault as plug optical fiber, drawing system and device DC power supply.After equal analog control system duty system or back-up system single system break down, the course of action of checking duty system and back-up system and the result of the action.Namely there is the problem of following two aspects in verification method and process: 1, only simulate single system fault, the not simulated dual system failure; 2, two cover systems successively fault in system failure sequential and failure time interval, particularly very short time is not considered during simulated failure.
Utility model content
The purpose of this utility model is to overcome existing technological deficiency, provides a kind of direct current transportation control device switched system, it is characterized in that: comprise
Protected host; the main control system be connected with protected host; described main control system is provided with control unit, automatic monitoring unit and switch unit; described switch unit is provided with automatic switch unit and manual switchover unit; its automatic monitoring unit is connected to automatic switch unit and manual switchover unit respectively, and described control unit is connected to automatic monitoring unit and switch unit.
Preferably, described control unit is provided with control logic unit and protection act command unit, and control logic unit connects protection act command unit, and protection act command unit connects manual switchover unit.
Native system considers interacting between DC control system two systems in handoff procedure, can automatically switch to different modes such as two cover system simultaneous faultss, successively fault or change into manual switchover.
Accompanying drawing explanation
Fig. 1 is frame principle of the present utility model.
Embodiment
In order to make the utility model object, technical scheme and advantage clearer, be now described in detail by reference to the accompanying drawings.
With reference to Fig. 1, a kind of direct current transportation control device switched system: comprise
Protected host 1; the main control system 2 be connected with protected host 1; described main control system 2 is provided with control unit 3, automatic monitoring unit 4 and switch unit 5; described switch unit establishes 5 to be equipped with automatic switch unit 8 and manual switchover unit 9; its automatic monitoring unit 4 is connected to automatic switch unit 8 and manual switchover unit 8 respectively, and described control unit 3 is connected to automatic monitoring unit 4 and switch unit 5.
Described control unit 3 is provided with control logic unit 4 and protection act command unit 5, and control logic unit 4 connects protection act command unit 5, and protection act command unit 5 connects manual switchover unit 9.
Operation principle is: (1), when operational system generation minor failure, another system is in stand-by state, and without any fault, then system automatically switches.After switching, minor failure system will be in stand-by state.When even more serious fault occurs new operational system, the system being now in stand-by state can also be switched back.(2) when back-up system generation minor failure, system does not switch.(3) when operational system generation catastrophe failure, if another system is in stand-by state, then system automatically switches.After switching, catastrophe failure system can not enter stand-by state.(4) when operational system generation catastrophe failure, and when another system is unavailable, then catastrophe failure system can continue to run.(5) when operational system generation emergency, if another system is in stand-by state, then system automatically switches.After switching, emergency system can not enter stand-by state.(6) when operational system generation emergency, if another system is unavailable, then locking direct current.(7) when serious or emergency occur back-up system, failure system should exit stand-by state.
More than be the embodiment of the technical program, the technical program not does any pro forma restriction to the utility model, have in any art and usually know the knowledgeable, if do not depart from the utility model carry in the scope of technical characteristic, utilize the utility model disclose the Equivalent embodiments changing or modify in the done local of technology contents, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
Claims (2)
