Abstract
The invention discloses a device and a method for restraining overvoltage of a contact network caused by regenerative braking. The reactive power compensation device is controlled to send out inductive reactive power by a control mode of voltage tracking of the contact network, and overvoltage of the contact network caused by regenerative braking of the locomotive is suppressed. The invention can inhibit the overvoltage of the contact network caused by regenerative braking of the locomotive, and ensure the power supply level of the contact network and the safe operation of the locomotive.
Description
Technical field
The invention belongs to traffic and transport field, relate in particular to the contact net overvoltage that a kind of regenerative braking causes and press downScheme processed.
Background technology
Alternating current traction electric power system is by the power taking of Three-phase Power Systems electricity, through tractive transformer transformation to contact net instituteThe single phase industrial frequence alternating current needing, for electric locomotive provides power for traction. Regenerative braking refers to that train is in the time of brakingThe kinetic energy of train is converted to the accessory system of electric energy for this train, or feeds back to electrical network. Nowadays,Electric locomotive adopts mostly hands over orthogonal drive technology, and this provides necessary condition for realizing regenerative braking.
When too fast the and retro-speed of locomotive running speed is larger or the regenerative braking of locomotive in the time of long and steep downgradeOperation, because motor reversal can produce a large amount of electric energy, if feed back to electrical network, can cause contact net mistakeVoltage, the performance to contact net and the safe operation of locomotive produce and have a strong impact on.
The contact net overvoltage problem causing for solving regenerative braking, the present invention is at contact net end and rail endEnd parallel reactive power compensator, by the control method of contact net voltage-tracing, this reactive power compensator canEnsure the safe operation of contact net power supply level and train.
Summary of the invention
The object of the invention is to be to provide a kind of superpotential device of contact net that regenerative braking causes that suppresses,The contact net overvoltage causing to suppress regenerative braking, ensures that the safety of contact net power supply level and locomotive is transportedOK.
The present invention solves its technical problem, and the technical scheme adopting is:
At contact net C end and rail R end parallel reactive power compensator RPC, this reactive power compensator is sent outGoing out lagging reactive power, can be dynamic switching reactor, SVC or SVG.
The present invention also aims to, provide to implement on said apparatus and suppress the contact net that regenerative braking causesSuperpotential method, the step of the control method adopting is:
Suppress the superpotential method of contact net that regenerative braking causes, by the controlling party of contact net voltage-tracingFormula is sent reactive power to contact net in the time that locomotive regenerative braking causes contact net overvoltage, suppresses due to againThe contact net overvoltage that raw braking causes, ensures the safe operation of power supply level and locomotive.
Compared with prior art, the Overvoltage suppressing scheme that regenerative braking of the present invention causes, by contact net CThe reactive power compensator RPC of end and the parallel connection of rail R end has solved the contact net mistake that regenerative braking causesThe problem of voltage, ensures the safe operation of contact net normal power supply and locomotive.
The most important thing is: adopt the control method of contact net voltage-tracing to carry out reactive power compensator RPCControl, make it send lagging reactive power, thereby solved the contact net overvoltage problem that regenerative braking causes,Thereby ensure the safe operation of contact net normal power supply and locomotive.
Brief description of the drawings
Fig. 1 is the Overvoltage suppressing schematic structure diagram that a kind of regenerative braking provided by the invention causes.
Detailed description of the invention
For the technological means that the present invention realizes is easy to understand, below in conjunction with concrete diagram and embodiment,Further set forth the present invention.
Embodiment
Encircle under eight Foshan of penetrating rail transit network important channel grow up to 30% of Zhaoqing with Pearl River Delta, Guangdong threeInterval, slope is example, and locomotive driving is at above-described long and steep downgrade, and mode of braking is regenerative braking, and speed is fast,And retro-speed is large, on same supply arm, without other locomotive operations, locomotive regenerative braking feeds back to electrical networkEnergy huge, cause the lifting of contact net voltage even to occur superpotential situation, to contact net and locomotive allProduce serious influence. Referring to Fig. 1, the Overvoltage suppressing scheme that a kind of regenerative braking causes comprises that traction becomesThe electricity SS of institute, traction net and reactive power compensator RPC, Fig. 1 is the Overvoltage suppressing side that regenerative braking causesCase structure chart, as shown in Figure 1, the more original traction substation SS of scheme provided by the invention is how a set ofReactive power compensator RPC, this reactive power compensator RPC is in contact net C end and the parallel connection of rail R end,It sends lagging reactive power, can be dynamic switching reactor, SVC or SVG, by contact net electricityPress the control mode of following the tracks of, control reactive power compensator RPC and send lagging reactive power, to suppress regenerationThe contact net overvoltage that braking causes.
More than show and described organization plan of the present invention, control method, general principle and of the present invention excellentPoint, the technical staff of the industry should understand, and the present invention is not restricted to the described embodiments, above-described embodimentWith description describe be organization plan of the present invention, control method and general principle, do not departing from thisUnder the prerequisite of bright spirit and scope, the present invention also has various changes and modifications, and these changes and improvements all fallEnter in claimed scope of the present invention, the claimed scope of the present invention by appended claims and etc.Effect thing defines.
