Abstract
The utility model relates to a voltage compensation device for a traction substation. A power supply arm of the traction substation is connected with a contact network, the contact network is connected with a phase control reactor, a thyristor control reactor is arranged between the tail end of the power supply arm of the traction substation and the contact network and connected with the phase control reactor, and an FC filter is arranged between the thyristor control reactor and the contact network. The voltage compensation device for the traction substation has the advantages that current in the phase control reactor is changed by a control angle of the thyristor control reactor, so the network voltage of the tail end of the power supply arm is improved. Moreover, the sum of the reactive power of the thyristor control reactor and the reactive power of a load is counteracted by the FC filter, so the voltage of the traction substation is maintained in a required range, the power factor of the power supply arm is improved, and electric energy loss is reduced.
Description
Technical field
The utility model relates to voltage compensating device, refers to a kind of voltage compensating device that is used for traction substation particularly.
Background technology
When electrified design of part ew line or existing railway capacity expansion revamping, tend to run into the situation of power voltage supply scarce capacity, need take indemnifying measure.Present voltage compensation to traction substation is employed in mostly establishes reactive power compensator in the traction substation; Perhaps establish adjustable reactive-load compensation equipment in the part traction substation; Promptly be employed in the mode of supply arm head end compensation; With raising traction substation head end and high voltage source inlet wire power factor, thereby reduce voltage drop.But this voltage compensation mode exists can't improve the supply arm power factor to improve the problem that net is pressed, and also has the deficiency that electric energy loss is big, floor space is big simultaneously.
Summary of the invention
The utility model purpose is to overcome the deficiency of above-mentioned prior art and a kind of voltage compensating device that is used for traction substation is provided; Pilot angle through thyristor-controlled reactor is to change the electric current in the Controlled Reactor; Realize the output of smooth adjustment reactive power, press thereby improve terminal net.
Realize that the technical scheme that the utility model purpose adopts is: a kind of voltage compensating device that is used for traction substation; The supply arm of said traction substation is connected with contact line; Said contact line connects Controlled Reactor; Be provided with thyristor-controlled reactor between the end of said traction substation supply arm and the contact line, said thyristor-controlled reactor is connected with said Controlled Reactor.
Be provided with the FC filter between said thyristor-controlled reactor and the contact line.
The utility model changes the electric current in the Controlled Reactor through the pilot angle α of thyristor-controlled reactor (TCR), realizes the output of smooth adjustment reactive power, thereby the terminal net of lifting supply arm is pressed.In addition, offset the reactive power and the load reactive power sum of thyristor-controlled reactor, make traction net electric substation voltage remain in the scope of requirement, improved the power factor of supply arm simultaneously through the FC filter.
The utility model has improved the terminal power factor of supply arm, effectively lifting net press, reduce the loss of electric energy.
Description of drawings
Fig. 1 is the structural representation that the utility model is used for the voltage compensating device of traction substation.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
As shown in Figure 1, be used for the voltage compensating device of traction substation, the supply arm of traction substation is connected with contact line 27.5kV bus 1, and 27.5kV bus 1 is connected with load 2.Be provided with thyristor-controlled reactor 3 between the end of traction substation supply arm and the contact line, thyristor-controlled reactor 2 is connected with said Controlled Reactor.Be provided with FC filter 4 between thyristor-controlled reactor 3 and the contact line.
The utility model comes comprehensively to provide pilot angle α through thyristor-controlled reactor 3 according to the terminal traction net of supply arm voltage u; Through change the electric current in the Controlled Reactor with α; Just the electric current in the inductance is realized the output of smooth adjustment reactive power, thereby the terminal net of lifting supply arm is pressed.In addition; The reactive power of thyristor-controlled reactor 3 can balanced load 2 the variation of reactive power; Make both sums be maintained certain constant; And the capacitive reactive power of this constant lagging reactive power through the FC filter offsets, and the final traction net electric substation voltage that makes remains in the scope of requirement, has improved the power factor of supply arm simultaneously.Reduce the loss of electric energy.
