Description
Technical field
The present invention relates to electric railway field, especially relate to a kind of electric energy adjustment device and the method thereof of electric railway traction for electrical domain that be applied to.
Background technology
In recent years, along with China's field of track traffic, especially the development of electric railway high speed, heavy loading, operation energy consumption and the power supply cost of railway are also more and more huger, therefore improve power delivery efficiency, reduce power consumption and power supply cost, significant for the energy-saving and cost-reducing and sustainable development of electric railway.About saving energy and reduce the cost of electric railway, aspect following two, still there is great potential at present.
On the one hand, at present China the AC transmission electric power locomotive of high volume applications can be by the regenerative braking electric energy feedback producing in braking procedure to tractive power supply system.When the locomotive under a supply arm is in on-position, the electric energy of its feedback can only be for other locomotive in traction state under same supply arm, but when there is no locomotive traction operation under same supply arm, or when the locomotive of running under power can not be completely consumed feedback electric energy, unnecessary braking electric energy can feed back to again three-phase alternating current electrical network by traction transformer.Electric energy feedback during to three phase network, is understood some and is lost on the line, and can cause the power quality problems such as negative-sequence current increase, voltage rising.The more important thing is, at present power department generally can be to the electric energy tariffing of loopback, therefore a large amount of feedback braking electric energy for tractive power supply system generation not economic benefit, caused waste of energy.
On the other hand, because the power of tractive load consumption is periodically variable, for maintaining at any time the electric energy equilibrium of supply and demand, the capacity of traction transformer is generally to design according to the maximum power of load consumption, and in most of the cases traction transformer all can oepration at full load, has so just caused the waste of capacity.Traction transformer capacity waste can cause cost to increase, and is mainly reflected in two aspects, and the one, the increase that traction transformer installation fee is used, the 2nd, due to two existing electricity prices processed of China, can cause the increase of basic charge as per installed capacity.
Meanwhile, that electrization railway draught load has is non-linear, fluctuation and the feature such as asymmetric, can cause the power quality problems such as the negative phase-sequence of tractive power supply system, idle, harmonic wave, has a strong impact on railway self and other users' power supply safety and reliability.At home and abroad conduct in-depth research for these problems, also proposed a lot of resolutions simultaneously.Various forms of static reacance generators (SVG), active filter (APF), power governor (RPC) and various hybrid devices are proposed again and again as improvement electric railway negative phase-sequence, scheme idle, harmonic wave.Simultaneously, electric phase-splitting link in existing railway traction power supply system not only can cause the loss of tractive force of train and speed, and the undue phase time of train causes electric transient process complexity between car net, when serious, will jeopardize traction net and train operation, and it is lower to cross phase-splitting link reliability, is one of link the weakest in tractive power supply system.Therefore, China's electric railway traction power supply system and technical elements thereof at present, three distinct issues below existing in the time realizing high speed and heavily loaded electric traction: operation energy consumption and the economy problems of (1) tractive power supply system; (2) take negative phase-sequence, idle, the power quality problem of harmonic wave as leading; (3) tractive force of train that electric phase-splitting causes and speed loss problem.In the middle of prior art, in the DC traction power-supply system of urban track traffic, the existing technical scheme that adopts energy storage device that train braking feedback electric energy is reclaimed and recycled at present.Meanwhile, in Three-phase Power Systems AC network, the technical scheme that adopts energy storage device or electric energy regulator to reduce equipment peaking capacity, raising place capacity utilance also has more introduction.But not yet have the electric energy adjustment device that is applied to electric railway single-phase AC traction power supply network in prior art, due to applicable electrical network form difference, can bring electric energy adjustment device in connected mode, composition structure, and bigger difference on practical function.Mainly there is following technological deficiency in electric railway traction power supply system of the prior art:
(1) electric energy adjustment device that in the prior art, not yet finds that there is similar structures is applied to the technical scheme of single-phase AC traction power supply network;
(2) the capacity utilance not relating in prior art by improving traction transformer reduces the energy consumption of electric railway and the concrete technical scheme of cost;
