Description
Technical field
The invention belongs to Computer Control Technology field, relate to a kind of power distribution cabinet electric power output control system.
Background technology
It is important part common in various electrical systems that power distribution cabinet is controlled in electric power output, and what obtain very extensive use is single control mode intelligent logical control system.Its essence is by a digital computer, to control in real time electric power output to control power distribution cabinet, completes to the electric power output of power consumption equipment and controls.Along with all kinds of intelligent controllers come into the market, the Based Intelligent Control application of electric power output control power distribution cabinet will be more and more extensive.
Advancing by leaps and bounds of modern technologies, make all kinds of electrical systems more and more higher to the requirement of power supply quality, especially need the distribution electrical system of long-term continuous operation, long-range operator-less, reliable, continuous, level and smooth power supply control, is the most basic assurance of guaranteeing whole system safe operation.Yet, in intelligent electric power output, control in the existing product of power distribution cabinet, up to the present, use be mostly single control mode intelligent logical control system.Because the power supply management system that single control mode intelligent logical control system is used has electric power, automatic switching function is not controlled in output, especially when output control unit breaks down, can not provide lasting power supply, so can not well adapt to the control and management demand that long-term, stable power-supplying demand equipment and frequent break-make are controlled kind equipment.
Summary of the invention
Technical problem to be solved by this invention is: a kind of power distribution cabinet electric power output control system is provided, can solves when electric power supply control system breaks down, automatically complete the switching controls under uninterrupted power supply state.
Technical scheme of the present invention is: a kind of power distribution cabinet electric power output control system, is characterized in that: described control system is mainly comprised of master control output unit, Standby control output unit and public control unit; Master control output unit is comprised of main distribution controller 1 and main contactor 3, and main contactor 3 on/off operations are controlled by main distribution controller 1 on/off control command; Standby control output unit forms by backing up distribution controller 4 and backing up contactor 5, and the 5 on/off operations of backup contactor are controlled by backup distribution controller 4 on/off control commands; Public control unit is by forming for electrical circuit breakers 2 and central control computer 6; For electrical circuit breakers 2 respectively to the main contactor 3 in master control output unit and the 5 input supply power voltages of the backup contactor in Standby control output unit; Central control computer 6 by data wire respectively with master control output unit in main distribution controller 1 and the backup distribution controller 4 in Standby control output unit complete data communication.
The invention has the beneficial effects as follows: the present invention utilizes control with computational intelligence technology, when electric power supply control system breaks down, can automatically complete the switching controls under uninterrupted power supply state; The inventive method is simple, and applied range is specially adapted to that various needs are long-range, the demand for control of the electrical system of operator-less power distribution cabinet to distribution.
Accompanying drawing explanation
Fig. 1 is the theory diagram of a kind of embodiment of power distribution cabinet electric power output control system of the present invention;
Wherein, 1-main distribution controller, 2-circuit breaker, 3-main contactor, 4-backup distribution controller, 5-backup contactor, 6-central control computer, 7-control transfer relay.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Referring to Fig. 1, the present invention comprises the steps such as circuit design, electric power output control gapless handover management in the specific implementation.
A) circuit design
(1) main distribution circuit consists of main distribution controller 1, circuit breaker 2, main contactor 3, fuse and power output end.Main contactor 3 is controlled by main distribution controller 1.
(2) backup power distribution circuit forms by backing up distribution controller 4, circuit breaker 2, backup contactor 5, fuse and power output end.Backup contactor 5 is controlled by backup distribution controller 4.
(3) active/standby part of control switching consists of central control computer 6 and control transfer relay 7.Control transfer relay 7 is controlled by central control computer 6.
B) control gapless handover management
(1) during system normal operation, be operated in acquiescence mode, by main distribution circuit, be responsible for electric power output and control.Main distribution controller 1 receives the control command of central control computer 6, drives main contactor 3 adhesives or disconnection, completes power supply control.Backup distribution controller 4 also in the middle of moving, receives the control command of central control computer 6, but Execution driven function not, backup contactor 5, in open position, guarantees the uniqueness of main distribution circuit control.
(2) when the transfer of data between main distribution control controller 1 or main distribution control controller 1 and central control computer 6 breaks down, central control computer 6 sends control conversion instruction, and drives control transfer relay 7 to change state of a controls.
(3) backup distribution controller 4 is received after the electric power output control switching command that central control computer 6 or control transfer relay 7 send, at once carry out electric power output control operation, start control and take over function program, by the control command receiving, drive backup contactor 5 adhesives or remain open.
(4) main distribution controller 1 is received after the electric power output control switching command that central control computer 6 or control transfer relay 7 send, start time delay timing program, to guarantee backing up distribution controller 4 and to back up contactor 5, have the sufficient time to complete control adapter.After timing finishes, main distribution is controlled controller 1 and is driven main contactor 3 to disconnect.
(5) after fault is got rid of, central control computer 6 carries out control switching again, main distribution controller 1 is carried out the program in (3) step that is similar to, and backup distribution controller 4 is carried out the program in (4) step that is similar to, and replys the electric power output of main distribution circuit and controls.
