Description

A kind of three-phase SVC compensation arrangement that is used for the electric railway traction side
Technical field
The invention belongs to electrified railway power supply, power electronic technology and power quality controlling field, specifically relate to a kind of three-phase SVC compensation arrangement that is used for the electric railway traction side.
Background technology
Along with developing rapidly of electric railway, electric railway has become a problem that can not be ignored to the influence of electric power quality.On the one hand, because China's electric railway traction power supply system all adopts the single phase power supply mode, electric locomotive is a single-phase load, and no matter which kind of mode of connection traction transformer takes, and all will inject bigger negative-sequence current to electric power system; On the other hand, electric locomotive adopts electronic power convertor, can produce harmonic current and inject electric power system.In addition, because the load of traction substation fluctuates at any time with the quantity of train in the supply arm and the running status of each train, so the electric railway load also has random fluctuation.
Be accompanied by the development of passenger traffic high speed and shipping heavy haul railway, new variation in various degree also can appear in the problems referred to above:
(1) increase gradually of traction load capacity, this will directly cause the negative-sequence current in the injected system to increase, and then the imbalance of three-phase voltage problem of electric power system is increased the weight of.Especially in the many areas of China, the capacity of short circuit of electrified railway power supply system will lag behind the development of electric railway load for a long time.Therefore, electric railway negative phase-sequence problem will become from now on matter of utmost importance in China's electrified railway electric energy quality.
(2) the DC driven electric locomotive is replaced by the AC driving electric locomotive gradually.The reactive current and the low-order harmonic electric current that are produced by electric locomotive will greatly reduce, AC drive locomotive load side power factor is very high, therefore the power quality problem that causes of stable state and dynamic reactive also will significantly weaken, and the three-phase voltage fluctuation will be mainly caused by the meritorious impact of single-phase electricity iron load.
At the power quality problem of above-mentioned electric railway, various indemnifying measures have been taked both at home and abroad.Wherein, commonplace method is at Traction Station installing fixed capacity (Fixed Capacitor, FC) compensation equipment.The common feature of this kind equipment is in reactive power compensation harmonic current to be administered.But because this class device belongs to the fixed compensation mode, can not flexible, can't realize dynamic compensation, compensation arrangement will send idle when supply arm zero load or underloading to system, cause busbar voltage to raise, unfavorable to locomotive work, and reactive power compensation is not enough when heavy duty.
Development along with power electronic technology and flexible power transmission and distribution technology, Static Var Compensator (Static Var Compensator, SVC), STATCOM (Static Synchronous Compensator, STATCOM) and based on the large-capacity railway power governor of self-turn-off device (Railway Static Power Conditioner RPC) begins to be applied to the power quality controlling of electric railway.Because electric railway is the high-voltage large-capacity load, therefore quality of power supply device is also had the demand of high-voltage large-capacity.For based on controlling devices such as the STATCOM of self-turn-off device and RPC, need to improve the capacity of device by technology such as many level, multipleization, cascades, the device design is complicated, cost is high, it is big to control difficulty.Relative STATCOM and RPC, the easier requirement of implement device high-voltage large-capacity of Static Var Compensator SVC based on thyristor, and have advantages such as simple in structure, that control method is ripe, project cost is low, therefore in electrified railway electric energy quality is administered, obtained using widely.
The SVC that is used for the electric railway compensation at present has dual mode usually: a kind of is to install single-phase static reactive-load compensator SVC respectively additional at two supply arms that draw side, adopt single-phase thyristor-controlled reactor (Thyristor Controlled Reactor, TCR) add the single-phase SVC that fixing electric capacity FC constitutes and be directly installed on the traction side, claim direct hanging type SVC again; Another kind is system side SVC, and the three-phase SVC that adopts single-phase thyristor-controlled reactor TCR to add the FC formation is installed in traction and becomes former avris, if be contained in the power system transformer substation, then can realize the concentrated quality of power supply compensation in the electric power system.
Traction side SVC directly is installed on the supply arm, by regulating the reactive power that the thyristor trigger angle realizes that smooth adjustment TCR is produced, the variation reactive power sum that idle variation of load and TCR are produced is a constant, the capacitive reactive power of this constant lagging reactive power and FC offsets, finally make the power factor of electrical network remain on higher level, traction net voltage is remained in the scope of requirement.In addition,, make device have the comprehensive compensation effect that the support of supply arm voltage, power factor controlling and harmonic wave suppress, have advantages such as the electric pressure of access is low, simplicity of design by the harmonic wave that FC branch road filtering electric locomotive produces.But this kind compensation way is owing to the energy flux that can't realize between the supply arm, so can not realize negative sequence compensation.Grid side SVC is connected to three-phase system, it is basic identical with traction side SVC that its power factor controlling and harmonic wave suppress principle, also can further utilize Si Tanmizi (Steinmetz) principle to realize the compensating of uncompensated load played the effect of compensation electric railway negative-sequence current.But because more than the three-phase system electric pressure higher (110kV), SVC need become and could insert by boosting, floor space and project cost that this will increase SVC have also increased the complexity on SVC manufactures and designs.
Summary of the invention
Power quality problems such as negative phase-sequence, harmonic wave and low power factor at above-mentioned electric railway load, the present invention proposes a kind of three-phase SVC compensation arrangement that is used for the electric railway traction side, the delta connection mode that adopts this device inserts the low-pressure side of traction transformer, and each all adopts single-phase thyristor-controlled reactor TCR fixed capacity FC in parallel structure mutually this device.According to the compensation demand of electric railway load, each of device can adopt asymmetrical design mutually, can realize comprehensively that the support of supply arm voltage, power factor controlling, the harmonic wave to the electric railway load suppresses and the negative sequence compensation function; Not only can overcome the shortcoming that the single-phase SVC of traction side can not compensate negative-sequence current, also can omit the step-up transformer of grid side SVC, be a kind of three-phase SVC compensation arrangement that integrates traction side SVC and grid side SVC advantage.
