Description

Be applied to the electric control system of air-conditioning equipment
Technical field
The present invention relates to a kind of power control technology, particularly relate to a kind of to the contract capacity and consume electric weight with electric control, the electric control system that is applied to air-conditioning equipment and method.
Background technology
Air-conditioning equipment is various interior of buildings, the electromechanical equipment of (for example office block, factory building building, restaurant, hospital, ultra merchant, supermarket, mass merchant, department store, theater, saloon) extensive use of particularly large-scale place of business and installation.Present air-conditioning equipment is integrated with air-conditioner, air conditioner (Air Handling Unit usually; AHU), pre-cooling type air conditioner (Precooling Air Handler; PAH), pressure fan (Fan Coil Unit, FCU), air exhauster (Exhaust Fan), cooling tower equipment, motor, frozen water transmission equipment and/or pumping unit even load facility.
For saving the electricity charge; The user of above-mentioned these large-scale business occasions usually can with Utilities Electric Co.'s capacity of signing a contract; So-called contract capacity is the electricity capacity of agreement; As the basis of basic charge as per installed capacity, can be divided into requirement contract capacity and two types of device contract capacity according to user power utilization kind difference.To be user's (being the contract customer) arrange 15 minutes average maximum demand values with the both sides of Utilities Electric Co. to requirement contract capacity is the contract capacity.Device contract capacity then for the user with the overall apparatus capacity of its consumer capacity of signing a contract.
But behind the capacity,, then can produce the problem of ultra about electricity consumption as surpassing this contract capacity in case sign a contract.Standard with Taiwan Power Company's design is an example, can be divided into two kinds of situation: one of which is " requirement contract capacity " ultra about electricity consumption, and promptly user's maximum demand exceeds its contract capacity of applying for.Exceed part and below 10%, collect basic charge as per installed capacity (promptly ultra about additional cost), exceed part and more than 10%, collect basic charge as per installed capacity by three times at the contract capacity by two times at the contract capacity.It two is " device contract capacity " ultra about electricity consumption, and promptly the utensil total capacity of user's actual device exceeds its contract capacity of applying for, exceeds partly all to handle by stealing.
In other words, electricity consumption in the contract range of capacity can be avoided ultra and be punished approximately, if exceed the contract consumption then need pay ultra about additional cost.On the other hand, just power supplier's angle is set out, if user's (being the contract customer) mostly can electricity consumption in the contract range of capacity, then can foresee desirable delivery more accurately, and then reduce and build the spent cost of too much power generating equipment.
Also have, general electricity consumption user (being non-contract customer) does not have a cover to improve electricity consumption to estimate yet, so that the power consumption excess still do not know, and just annoyance is endlessly behind the high cost of seeing on the electricity bill often.
Therefore, consult be fit to the contract capacity that user's requirement can not increase the expenditure of the electricity charge again, and behind the capacity of signing a contract, how obtain the optimum of the ultra additional approximately and not ultra about expense of overpaying, become the important topic of electrical management then with electricity providers.
It is to collect the historical record data of power consumption in the past that existing contract capacity is estimated, and selects the historical high peak or level off to the power demand on peak, the foundation when signing a contract capacity with electricity providers.But the mode of estimating of this contract capacity is not further considered the demand of user's (being the contract customer) for the preset desirable running of air-conditioning equipment, therefore may over-evaluate the contract capacity.For example; The historical record data of power consumption possibly all be that environmental goals temperature at air-conditioning equipment is set at the power demand under 24 degree Celsius in the past; And in fact preset ecotopia target temperature should be 26 degree Celsius; Then under the prerequisite that cooperates the environmental goals temperature control mechanism, should and add that the rational growth of load estimates the benchmark as the contract calculation of capacity with the demand of the preset desirable running of air-conditioning equipment, and no longer be to make benchmark with the historical record data of power consumption.On the other hand, the problem that with regard to general electricity consumption user (being non-contract customer), has the growth of load too.
Being no more than the contract capacity for the control power demand, seeing also Fig. 1, is in order to the existing application architecture sketch map of controlling power demand control system to be described.As shown in the figure; Requirement main control system 1 is connected to administrative center 12 through network 11; Administrative center 12 is connected to respectively through network 11 and is arranged on the power monitoring unit 13 that uses regional A, B and C, and 13 of power monitoring unit that are arranged at zones of different are respectively in order to monitor corresponding air-conditioning load 141,142 and 143.
During actual operation; The power monitoring unit 13 that requirement main control system 1 receives from zones of different is directed against the current electricity consumption requirement that corresponding air-conditioning load 141,142 and 143 is monitored, and gives the totalling statistics, the electricity consumption requirement that amounts to is compared with the predefined warning value of user again; In case when meeting or exceeding warning value; Requirement main control system 1 transmits the warning information to administrative center 12 through network 11 on the one hand, on the other hand also according to the air-conditioning load break sequence of user preset, through requirement main control system 1 or administrative center 12; Interrupting information is sent in air-conditioning load to preferential interruption, and interrupt.Through interrupting the mode of air-conditioning load, before overall electricity consumption requirement does not surpass the contract capacity, reduce the electricity consumption requirement, to avoid surpassing ultra about additional cost that the contract capacity is caused.
Above-mentioned existing power requirement technology, though can solve the problem that the electricity consumption requirement surpasses the contract capacity, the technological means of its solution but is directly load equipment to be interrupted.With the air-conditioning equipment is example, if directly air-conditioning equipment is interrupted, then the user of this air-conditioning equipment can't use this air-conditioning equipment, suitable inconvenience for the user.
In sum; How to provide a kind of contract customer's capacity of implementing contract that can supply according to the demand of the preset desirable running of air-conditioning equipment to estimate or supply non-contract customer's execution total electricity consumption to estimate; And can control the solution of current supply of electric power with flexible mode, real be urgency problem to be solved.
