[system energy efficiency technology]

System energy efficiency core technology be energy efficiency control system, energy efficiency control system itself has a link stage efficiency controller, and its is responsible for controlling mate to entirety of whole link energy efficiency control system and accepts the control coordination of central controller.

Efficiency coupling station comprises system energy efficiency controller and potential energy pump.System energy efficiency controller connects the efficiency controller of four links, is respectively application link efficiency controller, application link efficiency controller, the energy-conservation effect controller of storage rings, renewable sources of energy controller.By efficiency coupling station, Fourth Ring energy-conservation effect controller defines complete closed-loop control.Realize following Optimal Control Strategy:

The energy match of production link and application link regulates, and realizes dynamic peak regulation, space and time optimization;

On the basis of production link with application link energy match, add the adjustment storing link and regeneration link, cascade utilization and the process optimization of energy mix can be realized;

On the closed-loop control basis that four links realize, by the information integerated of central controller, garden mixing can be realized.

The Dynamic Matching of the energy, mobile equilibrium and dynamic optimization, achieve the gain of efficiency.

In sum, the difference that efficiency controller is different from traditional controller is mainly its unified allocation of resources for energy mix, instead of single adjustment, embodies the core concept of system energy efficiency.

The Secondary Control of efficiency completes between link efficiency controller, the such as input of production link efficiency controller comes from stationary point efficiency controller to electricity, heat, the Primary regulation of the monomer energy such as gas, create the input of energy mix, arrive production link efficiency controller again, the energy mix that production link efficiency controller is produced by Secondary Control exports, mate through system energy efficiency controller, be input to application link efficiency controller, simultaneously, introduce the adjustment storing link and the energy-conservation effect controller of regeneration ring, regulate the input end reaching energy mix three times that have passed through efficiency, enter the adjustment of next round, until the efficiency seen from application end reaches optimal objective value.

Efficiency is optimized and assessment

The optimization method of energy resource system is according to the height of level and can be roughly divided into five levels to the size of total system impact:

Structure optimization

Main finger is to the great change of topological structure of entire system energy flow process, as cascade system changes parallel system into, parallel system makes cascade system into, or to effect system Fourth Ring joint process can increase or reduce one or more link, such as from only having application link to change into, increase is produced, energy storage link.Structure optimization is great to systematic influence, is just by virtue of experience optimized in system design process traditionally, is just difficult to make change once system architecture sizing again.If custom-designed structure flow process comparatively flexibly, then likely reached the effect of one-piece construction dynamic optimization by some device of dynamic adjustments.Optimized algorithm at this time can be used for self-regulation structure parameter, is reached the effect of optimization of restructuring the use of energy by the adjustment of parameter.

Method optimizing

The upgrading of individual equipment more important to system and the breakthrough innovation of energy utilization patterns, thus cause the larger lifting of entire system efficiency.The efficiency lift technique such as using heat pump to combine with energy storage makes full use of environment potential energy, increases substantially electric conversion efficiency; Regenerative combustion technology is adopted to significantly improve coal gasification conversion ratio.

Space and time optimization

The Dynamic Matching of energy production application, peak regulation round the clock, across energy storage in season etc., space optimization comprises the energy complementation adjustment to different spaces field.Such as adopt energy-storage battery to regulate photovoltaic power fluctuation, adopt the cold and hot technology of storage to regulate buildings day and night temperature, increase the COP coefficient of heating/refrigeration; Adopt and improve utilization efficiency of heat energy further across storing up cold and hot technology season.

Process optimization

Finely tuned by each equipment steady state operation parameter, to reduce total system energy consumption, the scope that above-mentioned parameter regulates does not comprise and changes the parameter of system topology, and parameter is generally continuous variable and away from the critical point of nonlinear mutation.Such as in the cascade utilization of heat energy, increase waste heat efficiency, improve the energy conversion efficiency of system.

Stationary point is optimized

The Optimal improvements of individual equipment or device, but do not comprise revolutionary innovative technology, or the raising of individual equipment is less to whole system efficiency raising effect.Such as, intelligent electric appliance in buildings is energy-conservation, and low-power consumption information technoloy equipment is energy-conservation, and industrial machine pumping unit adopts converter technique fine adjustment frequency to reach optimum efficiency.

The real time data that system energy efficiency evaluation system gathers according to DCS or carry out Energy Efficiency Analysis by HYSYS dynamic similation data, comprising:

[efficiency gain mechanism]

Primary energy is converted to electricity, heat, the secondary energy such as cold that directly can utilize for energy source use link by energy production link, although compare traditional application mode, the pattern of this cascaded utilization of energy significantly improves the efficiency of energy utilization of system, but the energy structure that production link exports is relatively fixing, this defines contradiction with the continuous change of application link to secondary energy demand percentage.Common manufacturing side electricity, ratio of specific heat is routine is generally 1: 1, and common application end electricity, ratio of specific heat is routine is 1: 2 to 1: 3, this situation usually mean needs directly the high-grade energy of consumption if electric energy is to obtain required low-grade energy as heat or cold.The heat of this heating and refrigeration demand and the grade of cold lower, directly adopt electric energy to produce and will cause larger energy utilization waste.

Efficiency gain apparatus utilize potential energy pump as the equipment such as heat pump by environment low-grade, not directly promoted by the environment potential energy that energy source use link utilizes, the degree that can be utilized is reached with the environment potential energy that a small amount of high-grade energy is several times as much as self as electrical energy drive, relative to traditional energy utilization mode, add the energy system of efficiency gain apparatus, its Energy harvesting usefulness can further improve.

Compared with general potential energy pumping system, efficiency gain apparatus has three obvious differences.

The first, efficiency gain apparatus is connected with energy storage link.The integrated operation efficiency COP of general heat pump is usually about 3, and they directly draw environment potential energy from environment, and owing to there is the larger lifting temperature difference, the efficiency of system is also corresponding lower.Efficiency gain apparatus is connected with energy storage link, energy storage link in two sub-sections, first part be across time accumulator system, this system storage by solar energy optical-thermal and radiation refrigeration technology between daytime and the heat produced night and cold, then when application end needs heating and refrigeration, for potential energy pump provides heat and the cold of required lifting.Because these energy be stored itself have had certain grade, in lifting process, therefore only need to consume less energy just can reach application link energy demand grade standard, now the COP of system can reach more than 6.Certainly, across time accumulator system capacity have a definite limitation, when the amount of energy to be hoisted that it stores is not enough, the Part II just needing to start energy storage link namely across accumulator system in season come for across time accumulator system additional heat or cold.Utilize the cold of environment and heat directly to store in systems in which respectively with summer in the winter time across accumulator system in season, and discharge in contrary season.

The second, the electric energy that efficiency gain apparatus uses can be provided by photovoltaic, wind-force or wind-light complementing power generation device.Because the efficiency of efficiency gain apparatus is very high, COP can reach more than 6, and power consumption needed for whole system comparatively conventional heat pump system can reduce by more than 50 and even only have 1/3.Electric energy is sent directly to system energy efficiency controller, directly controls, provides and delivers to potential energy pump, guides the high-grade energy of this green for promoting the environment potential energy stored by accumulator system, becomes the high-grade energy that can be employed link and directly utilize.

3rd, the potential energy pump of efficiency gain apparatus and system energy efficiency controller are integrated couplings, and system energy efficiency controller is responsible for carrying out entirety to the efficiency of efficiency four link system and is controlled and the control coordination accepting ecological city system energy efficiency controller.System energy efficiency controller is by calculating the optimization of collection of ecological city Global Information, then electricity, heat, cold homenergic load instruction is assigned, comprehensive adjustment coupling is carried out accordingly by efficiency gain apparatus, under the prerequisite of the loads such as satisfied entirety is electric, hot, cold, accomplish that total system efficiency is optimum as far as possible.

Generally speaking, system energy efficiency gain mechanism is exactly by a small amount of sun power of efficiency gain apparatus, the contour quality energy of wind energy, merge the intelligent information of people's input, the environment potential energy carried and promote in environment is removed by the potential energy pump of efficiency gain apparatus, make it the available energy promoting into different grade, achieve the increase of overall available energy, thus improve the overall efficiency of system.The function of this " art is good for strength ", is referred to as " efficiency gain ".Current stage efficiency gain apparatus uses cool and thermal power multiple-supplying device and heat pump as Main physical carrier, and adopts intelligent control technology carry out enforcement optimization to this process and control.Information flow transmits from production, application, regeneration and storage to system energy efficiency controller, system energy efficiency controller makes efficiency optimization, matching instruction accordingly, starting potential energy pump is that application end mates the demands such as hot and cold, electric, coordinates conversion and the transmission of other energy simultaneously.
