Description
Technical field
The invention belongs to the management system field of power supply and new forms of energy, more particularly, relate to intelligent scheduling manager and the control method thereof of a kind of multiple-way supply automatic switchover.
Background technology
Energy crisis accelerates the exploitation of new forms of energy, and most of new forms of energy are reproducible natural energy resources, as solar energy, wind energy etc.Natural energy resources is affected by environment comparatively large, and solar energy does not generate electricity overcast and rainy, and wind energy does not generate electricity at calm weather yet.In order to not affect load electricity consumption, following power supply system must be the distributed system of multiple-energy-source, and multiple-energy-source is powered and needed reasonably to dispatch according to energy scenario and manage, wherein switch and be absolutely necessary, and need controlled switching, intelligence management and dispatch automatically.
Existing power management techniques, handoff technique and power source loads connecting device function singleness, based on manual operation, even if there is the new technology of some automations, new equipment, also for certain function, only emphasize the requirement to power supply, only consider to switch the mode realized, or only solve the load management of power use, these situations can be seen in following data.
" intelligent power switch controller " (" popular electricity consumption ", number of the edition 43-1123/TK, 03 phase in 2005), be to solve in electric power system, some power electronic equipments often need to run under different conditions, or use different working powers.For example: alternating current impression formula motor frequency change switches to the dynamic grid-connected switching etc. of power frequency operation, generating equipment after starting, need automatic switchover different electrical power or merge different electrical networks, steadily switch or merge without impacting in order to ensure realizing safely and fast, use intelligent power switch controller.The function of this intelligent power switch controller, the automatic steady mainly meeting some specific loads switches without impact.
" a kind of research and apply of multiple power supplies intelligent control system " (Zhang Wei, plumcot spring, Wang Zhanguo, " instrument and meter standardization and metering ", number of the edition 11-3365/TK, in June, 2003) describe a kind of real-time control system for railway signal duplex feeding supply voltage, electric current in the document.This system can drop into the good road of supply voltage quality by regulation technical indicator automatically, has display, inquiry, the functions such as print fault data simultaneously.This multiple power supplies intelligent control system only considers the selection to power supply.
Application number: 201110396633.5, the applying date: 2011-12-03, the patent of invention " a kind of solar energy and mains hybrid controller " of publication date 2012-03-07, be mainly used in solar energy deficiency when causing storage battery power supply afc voltage is not lower, load supplying approach switches to mains-supplied from storage battery power supply, with the reliability of proof load work.It is also the selection only considered power supply that this duplex feeding switches.
Above three examples are all that only consideration is to the requirement of power supply and selection.
Application number: 200820230756.5, the patent " multiple power supplies intelligent switch " of the applying date: 2008-12-02, mainly describes how to do switch with multichannel bidirectional triode thyristor switching switch circuit.
Application number: 201020227659.8, the patent " intelligent dual-power automatic transfer switch controller " of the applying date: 2010-06-09, main describes diverter switch how with by shell, transformer, wiring board, lid, spiral head, cable, aviation plug, form from merit screw etc.
These above two patents only considered the mode switching and realize.
Application prior art load management of power use product 1 " intelligent terminal management of power use device " (or " intelligent terminal power consuming administrative system ") of manufacturing, all prohibit the use the place of the resistive loads such as immersion heater, electric furnace, insulating pot to be mainly used in school, enterprise, construction site dormitory and hospital ward etc.This management of power use device is also known as electricity-saving appliance.This management function is different from emphases of supervision of the present invention.
The load management of power use product 2 " terminal electricity consumption intelligent management system " that application prior art is manufactured, it is based on intelligent network kilowatt meter reading-out system, coordinate the management software of complete function and remote control device to complete the management of power use of terminal power consumer, realize the analytic function such as user power utilization situation, anti-electricity-theft, load condition, multistage line loss simultaneously.This terminal electricity consumption intelligent management system mainly solve estate management and power supply enterprise ammeter difficult charge, manage the problems such as difficult.This management function and emphases of supervision of the present invention are not identical yet.
Above two routine products only considered some management of power use of load, i.e. brownout and the charge of electricity management.
In sum, although multiple power supplies management system of the prior art and close product thereof have automatic switching function and intelligent management function, but its function synthesized is inadequate, as " intelligent power switch controller " meets multiple-energy-source application, but can not meet the requirements at the higher level of load.Due to the improvement of the modern life, the continuous increase of a large amount of electrical load such as household appliances, computer, not only require that power supply system can supply enough electric power, also require that power supply is convenient, controlled, have better stability and fail safe, therefore power supply and electricity consumption both sides have higher requirement to power supply system of connections.
For the prospect of following intelligent power, " electrical measurement and instrument " 09 phase in 2010 " design and implimentation towards the family comprehensive energy management system of intelligent power " proposes to form home network with smart machines such as intelligent electric meter, smart-interactive terminal, smart jacks, support access and the metering of the system or equipment such as distributed energy, electric automobile, and there is the function such as comprehensive family energy consumption monitoring and energy source optimization management, household electrical appliance Based Intelligent Control and user's two-way interaction.Build thus electrical network and user's energy flow, information flow, Business Stream real-time interactive novel for electricity consumption relation, meet the requirement to advanced technology, economical and efficient, various, the flexible interaction of service and close friend's opening of intelligent power under intelligent grid.
Fine prospect described above, needs corresponding smart machine support.The present invention's " multiple-way supply intelligent scheduling manager and control system thereof " is exactly a kind of novel intelligent dispatching management equipment provided for realizing this prospect.The present invention combines power supply, load and switches the requirement of three aspects, by tripartite's surface function comprehensive Design, combines together, has both considered the net side handoff functionality carried out power requirement; Consider multiple power supplies and the handoff functionality of multichannel loading automatic steady and the intelligent management function of load electricity consumption again.Of the present inventionly focus on dispatching management, by its rational management, realize energy source optimization management and load electricity consumption intelligent management.
