Abstract
The utility model belongs to the technical field of power electronic, concretely relates to voltage control intelligent control device. It can overcome the shortcoming of traditional auto transformer formula regulator, can reach to switch to strike for a short time, and on -load switch is longe -lived, but advantages such as reactive compensation, the intelligent voltage control of the long distribution electric wire netting of specially adapted.
Description
technical field:
The invention belongs to electric and electronic technical field, be specifically related to a kind of voltage-regulation intelligent controlling device.
technical background:
Due to the actual conditions of power distribution network, there is the feature of region dispersion, supply line head, therefore voltage is low when electric terminal often exists peak of power consumption, fluctuate large situation, has a strong impact on power supply quality and reliability.
summary of the invention and beneficial effect:
This programme describes a kind of new-type autotransformer on-load voltage regulation and compensates with switch protecting the device combined.It can overcome the shortcoming of traditional auto-transformer type regulator, can reach switching shock little, and the loaded switch life-span is long, can the advantage such as reactive power compensation, is specially adapted to long distrbution network intelligent voltage and regulates.
Technical scheme of the present invention is to provide a kind of voltage-regulation intelligent controlling device, comprises Multiple coil autotransformer TTK(wherein common winding S1, tap-changing windings S2, control power supply winding S3, protection compensative winding S4), on-load voltage regulating switch TQS, Current Transmit, voltage transformer pt, switch protecting compensating module (wherein thyristor SCR, electric capacity C), controller PLC(or other intelligent controller), it is characterized in that: input connects autotransformer tap-changing windings S2 in there being the mode regulation voltage carrying and regulate by on-load voltage regulating switch TQS, and picks out through Current Transmit at stiff end, voltage transformer pt is connected to output, controller PLC(or other intelligent controller) supplied control electricity and utilize Current Transmit and voltage transformer pt to device outlet voltage by control power supply winding S3, electric current is monitored, computing also controls the dynamic adjustments that on-load voltage regulating switch TQS action realizes voltage, and protection compensative winding S4 connects thyristor SCR and is connected to electric capacity C formation switch protecting compensating module again.
Controller PLC(or other intelligent controller) to control that switch protecting compensating module drops into on-load voltage regulation gear switch be that the impact produced is carried out absorbing and also the part reactive power that produces of compensated line and transformer can be improved the quality of power supply with protect electric capacity simultaneously for the conducting of carrying out Monitoring and Controlling thyristor to the every data of electrical network, control on-load voltage regulating switch realizes the adjustment of real-time output voltage in the switching of the position of tap-changing windings simultaneously.
With autotransformer on-load voltage regulation Method compare, the switch protecting compensating module increased can to being that the impact produced be carried out absorbing and the part reactive power that produces of compensated line and transformer can improve the quality of power supply to on-load voltage regulation gear switch, and suitably select protection compensative winding voltage that thyristor (but not high-pressure thyristor string) can be utilized to substantially increase fail safe as capacitor fling-cut switch, reliability and response speed, controlling power supply winding adopts triangle connected mode to have inhibitory action to triple-frequency harmonics with protection compensative winding, this equipment is made to have switching shock little, the loaded switch life-span is long, the advantages such as dependable performance is stable.
accompanying drawing explanation:
Fig. 1 is typical line chart of the present invention
embodiment:
In FIG, TTK Multiple coil autotransformer is by S1 common winding, S2 tap-changing windings, S3 controls power supply winding, S4 protects compensative winding composition, input is connected to S2 tap-changing windings diverse location by TQS on-load voltage regulating switch, S2 tap-changing windings one fixed position is through CT current transformer, PT voltage transformer is connected to output, S4 protects compensative winding to connect SCR thyristor and is connected to C electric capacity formation switch protecting compensating module again, S3 controls power supply winding switching PLC for its power supply, CT current transformer, PT voltage transformer holding wire is connected to PLC to monitor electric network data.
Several embodiments of just this invention of foregoing description, various illustrating does not limit essence of an invention Composition of contents, the amendment that person of an ordinary skill in the technical field has made aforesaid embodiment after having read specification or distortion, do not deviate from essence of an invention and scope.
