Description
Technical field
The utility model belongs to battery energy storage field, specifically relates to construction and the application of the energy-accumulating power station system of lithium ion battery.
Background technology
Constantly reduce at traditional fossil energy, energy supply day is becoming tight, today that environmental pollution constantly increases the weight of, and the topic of the environmental protection energy is once being brought into schedule by the whole world.All wideling popularize various types of electric automobile in global range a few days ago; this crisis alleviating fossil energy to a certain extent and the pollution reduced environment; but also bring a new problem simultaneously; these are unmatched by the battery life-span that is current and vehicle adopted in a large number; and these electrokinetic cells are not as dealt carefully with; not only can bring new pollution to environment in the future, the use cost of adding users, has influence on the development of new forms of energy industry simultaneously.The construction of energy-accumulating power station effectively can solve the battery problems of electric automobile " retired ".In addition on the one hand, energy-accumulating power station system in conjunction with wind-light complementary system, can have several large function application such as " Load Regulation, cooperation new forms of energy access, make up line loss, power back-off, the raising quality of power supply, isolated power grid, peak load shifting " simultaneously.
The construction of current battery energy-accumulating power station is also in the design starting stage, and be confined to energy-storage battery quantity, the disposable difficulty built up of power plant construction is larger; Secondly, directly in parallel very high to battery with two side terminals requirement between different battery system, otherwise circulation between battery can be caused to exist, affect safety and the life-span in power station.
Utility model content
For the technical problem existed in prior art, the purpose of this utility model is to provide a kind of energy-accumulating power station based on ac bus.
The utility model object can be achieved through the following technical solutions:
A kind of energy-accumulating power station based on ac bus, comprise battery management system, DC control cabinet, two way convertor, AC switch cubicle, two-way transformer, high-tension switch cabinet and background monitoring and EMS, described battery management system, DC control cabinet, two way convertor, AC switch cubicle is in parallel, described battery management system, DC control cabinet, two way convertor, bi-directional conversion between 400VAC and 10KVAC is realized by two-way transformer and high-tension switch cabinet after AC switch cubicle parallel connection, described background monitoring and EMS are monitored and feedback DC control cabinet, two way convertor signal.
Described two way convertor realizes direct current and the bi-directional conversion exchanged.
Described AC switch cubicle realizes connecting between subsystem with ac bus and being separated.
Described two-way transformer realizes bi-directional conversion between 400VAC and 10KVAC.
The beneficial effects of the utility model: this new design structure is simple, efficiently solve problem inconsistent between battery system, oppose between each subsystem work mutually, can realize the built by separate periods of large-scale energy-accumulating power station, commissioning & operation, be convenient to the maintenance in system later stage.
Accompanying drawing explanation

In figure: 1-battery management system (BMS); 2-DC control cabinet; 3-two way convertor (PCS); 4-AC switch cubicle, the two-way transformer of 5-; 6-high-tension switch cabinet; 7-background monitoring and EMS.
Embodiment
For further describing the utility model, below in conjunction with drawings and Examples, the utility model is described in further detail, but therefore the utility model is not limited within described scope of embodiments.
As Fig. 1, Fig. 2, a kind of energy-accumulating power station based on ac bus, comprise battery management system 1, DC control cabinet 2, two way convertor 3, AC switch cubicle 4, two-way transformer 5, high-tension switch cabinet 6 and background monitoring and EMS 7, described battery management system 1, DC control cabinet 2, two way convertor 3, AC switch cubicle 4 is in parallel, described battery management system 1, DC control cabinet 2, two way convertor 3, bi-directional conversion between 400VAC and 10KVAC is realized by two-way transformer 5 and high-tension switch cabinet 6 after AC switch cubicle 4 parallel connection, described background monitoring and EMS 7 are monitored and are fed back DC control cabinet 2, two way convertor 3 signal, described two way convertor 3 realizes direct current and the bi-directional conversion exchanged, described AC switch cubicle 4 realizes connecting between subsystem with ac bus and being separated, described two-way transformer 6 realizes bi-directional conversion between 400VAC and 10KVAC.
Operation principle: as shown in Figure 1, Figure 2, export DC control cabinet 2 after battery management system 1 has connected to, both positive and negative polarity is controlled by DC controller respectively; DC component is delivered to two way convertor 3 and carries out inversion output AC 400V three-phase electricity after DC control cabinet 2, is transported to dual transformer 5, is finally connected with 10KV AC network by AC switch cubicle 4.Battery management system 1 main frame carries out real-time communication by CAN and two way convertor 3, and ensure the constrained input of system capacity, battery management system 1 main frame and background monitoring realize data by serial communication and monitor in real time; Two way convertor 3 and background monitoring and EMS 7 are realizing while data monitor in real time by LAN communication, the management realize energy input, exporting.
Multichannel subsystem can carry out connecting, debugging respectively, realizes the connection with main system more afterwards, thus reach the function of capacity extensions by exchanging the cabinet that opens the light.In actual motion, can EMS be passed through, require the power constrained input of each subsystems respectively.In addition, in system maintenance process, realizing being separated of certain subsystems and whole system by AC switch cubicle, carrying out when not affecting whole system work.
Above content is only to design example of the present utility model and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of utility model or surmount this scope as defined in the claims, protection range of the present utility model all should be belonged to.
