The gordian technique of pan-energy network

[system energy efficiency technology]

System energy efficiency core technology be the efficiency control system, the efficiency control system itself has a link stage efficiency controller, its is responsible for integral body control coupling of whole link efficiency control system and the control of accepting central controller are coordinated.

Efficiency coupling station comprises system energy efficiency controller and potential energy pump.The system energy efficiency controller connects the efficiency controller of Fourth Ring joint, is respectively applied links efficiency controller, applied links efficiency controller, the energy-conservation effect controller of storage rings, renewable sources of energy controller.By efficiency coupling station, the energy-conservation effect controller in Fourth Ring has formed complete closed-loop control.The Optimal Control Strategy that is achieved as follows:

The energy match and regulate of production link and applied links realizes dynamic peak regulation, space and time optimization;

Production link and applied links can be flux matched the basis on, add the adjusting that stores link and regeneration link, can realize the cascade utilization and the process optimization of energy mix;

On the closed-loop control basis that the Fourth Ring joint is realized,, can realize that the garden mixes by the information integration of central controller.

The Dynamic matching of the energy, mobile equilibrium and dynamic optimization have been realized the gain of efficiency.

In sum, the difference that the efficiency controller is different from traditional controller mainly is its unified allocation of resources for energy mix, rather than single adjusting, has embodied the core concept of system energy efficiency.

The secondary of efficiency is regulated and is finished between link efficiency controller, for example the input of production link efficiency controller be come from stationary point efficiency controller to, heat, the once adjusting of the monomer energy such as gas, produced the input of energy mix, arrive production link efficiency controller again, production link efficiency controller is regulated the energy mix output that produces by secondary, mate through the system energy efficiency controller, be input to applied links efficiency controller, simultaneously, introduce the adjusting that stores link and regeneration link efficiency controller, pass through three times of efficiency and regulated the input end that has arrived energy mix, entered the adjusting of next round, till the efficiency of seeing from application end has reached the optimal objective value.

Efficiency is optimized and assessment

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

Structure optimization

Mainly refer to the great change of topological structure to entire system energy flow process, change parallel system into as cascade system, parallel system makes cascade system into, perhaps to effect system Fourth Ring joint process increasing or reduce one or more links, such as increasing production, energy storage link from having only applied links to change into.Structure optimization is great to systematic influence, just by virtue of experience is optimized in system design process traditionally, in case the system architecture typing just is difficult to make change again.If custom-designed structure flow process comparatively flexibly, then might reach the effect of one-piece construction dynamic optimization by some device of dynamic adjustments.Optimized Algorithm at this time can be used for the self-regulation structure parameter, and the adjusting by parameter reaches the optimization effect of restructuring the use of energy.

Mode is optimized

To the upgrading of the more important individual equipment of system and the breakthrough innovation of energy utilization patterns, thereby cause the bigger lifting of entire system efficiency.The efficiency lift technique that for example uses heat pump to combine with energy storage makes full use of environment potential energy, increases substantially electric conversion efficiency; Adopt regenerative combustion technology obviously to improve the coal gasification conversion ratio.

Space and time optimization

The Dynamic matching that energy production is used, peak regulation is striden energy storage in season etc. round the clock, and space optimization comprises regulates the energy in different spaces field is complementary.For example adopt energy-storage battery to regulate the photovoltaic cell power swing, adopt the cold and hot technology of storage to regulate the buildings day and night temperature, increase the COP coefficient of heating/refrigeration; Employing is striden the cold and hot technology of storage in season and is further improved utilization efficiency of heat energy.

Process optimization

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

The stationary point is optimized

The optimization of individual equipment or device improves, but does not comprise revolutionary innovative technology, and perhaps the raising of individual equipment is less to total system efficiency raising effect.For example the intelligent electric appliance in the buildings is energy-conservation, and the low-power consumption information technoloy equipment is energy-conservation, and industrial pump equipment adopts converter technique and accurate regulating frequency to reach optimum efficiency.

The system energy efficiency evaluation system is carried out the efficiency analysis according to the real time data of DCS collection or by HYSYS dynamic similation data, comprising:

(1) (fire with) analytical model: according to parameters such as temperature, pressure, flow, component determine each burst logistics and can flow physics (fire with), chemistry (fire with) and diffusion (fiery using); Use fuel-Product Definition is determined the production function of each unit, and (fire is used) damage of definite each link, (fiery using) efficient and (fiery using) damage coefficient;

(2) thermoeconomics model: set up secular equation, (fire is used) cost equation, the thermoeconomics cost equation of system, obtain (fire is used) cost and (fiery using) economics cost that each strand (fire is used) flows; Utilizing the second law of thermodynamics and thermoeconomics structural theory to make up the complete Fourth Ring joint (fire is used) of a cover analyzes and the thermoeconomics analytical approach.With each concrete production link of theme park is example, use has been analyzed the thermodynamic process and the regularity of distribution thereof that system cost forms based on the production reciprocal process between thermoeconomics model, (fire is used) cost and the thermoeconomics cost model quantification equipment of fuel-Product Definition.

(3) performance diagnogtics model: using the thermoeconomics diagnostic model, is benchmark with the reference floor data, obtains actual condition and with reference to the deviation between the operating mode, analyzes and quantize to cause the reason of deviation;

(4) Optimization Model: set up the 3E Optimization Model of considering efficient (Efficiency)-economy (Economy)-environment (Environment), system is carried out complex optimum, design optimization and operation optimization

[efficiency gain mechanism]

But primary energy is converted to electricity that energy supply source applied links directly utilizes, heat, secondary energy such as cold by the energy production link, although compare traditional application mode, the pattern of this cascaded utilization of energy has significantly improved the efficiency of energy utilization of system, but the energy structure relative fixed of production link output, this and applied links have formed contradiction to the continuous variation of secondary energy demand percentage.Common manufacturing side electricity, ratio of specific heat example are generally 1: 1, and common application end electricity, ratio of specific heat example are 1: 2 to 1: 3, and this situation means that usually needs directly consume high-grade energy such as electric energy and obtain needed low-grade energy such as heat or cold.The heat of this heating and refrigeration demand and the grade of cold are lower, directly adopt electric energy to produce and will cause bigger energy utilization waste.

The efficiency gain apparatus utilizes equipment such as potential energy pump such as heat pump that the environment potential energy low-grade, that not directly utilized by the energy source use link in the environment is promoted, drive the environment potential energy that is several times as much as self with a spot of high-grade energy such as electric energy and reach the degree that can be utilized, with respect to traditional energy utilization mode, add the energy system of efficiency gain apparatus, its energy utilizes usefulness can further improve.

Compare with general potential energy pumping system, the efficiency gain apparatus has three tangible differences.

The first, the efficiency gain apparatus is connected with the energy storage link.Usually about 3, they directly draw environment potential energy to the integrated operation efficiency COP of general heat pump from environment, owing to there is the bigger lifting temperature difference, the efficient of system is also corresponding lower.The efficiency gain apparatus is connected with the energy storage link, the energy storage link in two sub-sections, first part is an accumulator system when striding, the storage of this system by solar energy optical-thermal and radiation refrigeration technology between daytime and heat and the cold produced night, when application end needs heating and refrigeration, provide the heat and the cold of required lifting for the potential energy pump then.Because these stored energy itself have had certain grade, therefore in lifting process, only need consume less energy and just can reach applied links energy demand grade standard, this moment, the COP of system can reach more than 6.Certainly, the capacity of accumulator system has certain limitation when striding, and when its amount of energy to be hoisted of storing was not enough, the second portion that just needs to start the energy storage link was promptly striden the season accumulator system and come accumulator system additional heat or cold when striding.Stride the season accumulator system and directly be stored in the system with cold that utilizes environment summer respectively and heat in the winter time, and discharge in opposite season.

The second, the employed electric energy of efficiency gain apparatus 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 the required power consumption of total system can reduce by more than 50 than the conventional heat pump system and even only have 1/3.Electric energy directly is sent to the system energy efficiency controller, and the potential energy pump is given in directly control, dispensing, guides the high-grade energy of this green to be used to promote the environment potential energy of being stored by accumulator system, becomes to be employed the high-grade energy that link is directly utilized.

The 3rd, the potential energy pump of efficiency gain apparatus and system energy efficiency controller are integrated couplings, and the system energy efficiency controller is responsible for the efficiency of efficiency Fourth Ring joint system is carried out the whole control coordination of controlling and accepting ecological city system energy efficiency controller.The system energy efficiency controller calculates by the optimization of collection to the ecological city Global Information, assign electricity, heat, the instruction of cold homenergic load then, carry out the comprehensive adjustment coupling by the efficiency gain apparatus in view of the above, satisfying under the whole prerequisite of loading such as electric, hot, cold, accomplish total system efficiency optimum as far as possible.

Generally speaking, system energy efficiency gain mechanism is exactly to pass through the efficiency gain apparatus with high-grade energy such as a spot of sun power, wind energies, merge the intelligent information of people's input, potential energy pump by the efficiency gain apparatus removes to carry and promote the environment potential energy in the environment, make it to promote into the available energy of different grades, realize the increase of overall available energy, thereby improved the whole efficiency of system.The function of this " art is good for strength " is referred to as " efficiency gain ".Current stage efficiency gain apparatus uses multi-joint supplying apparatus of cool and thermal power and heat pump as the Main physical carrier, and adopts intelligent control technology that this process is implemented to optimize and control.Information flow transmits to the system energy efficiency controller from producing, use, regenerate and storing, the system energy efficiency controller is made efficiency optimization, matching instruction in view of the above, starting the potential energy pump is demands such as the application end coupling is hot and cold, electricity, coordinates the conversion and the transmission of other energy simultaneously.

On the basis of production link and applied links efficiency coupling, add the efficiency adjusting that stores link and regeneration link, can realize the cascade utilization and the process optimization of many kinds energy mix;

On energy-conservation effect closed-loop control basis, Fourth Ring, by the information integration of system energy efficiency controller, can realize the Dynamic matching of regional energy mix, mobile equilibrium and dynamic optimization.Realize the gain of district system efficiency.

Potential energy pump in the efficiency gain apparatus is finished the closed loop utilization and the efficiency gain of Fourth Ring joint energy mix.Potential energy pump and energy storage link cooperate, finish the circulation and the utilization of waste heat, overbottom pressure, underground heat, the energy mix of output directly arrives the applied links coupling and utilizes, realized the closed loop utilization of Fourth Ring joint energy mix, by absorbing environmental potential energy repeatedly, the gain effect of realization efficiency that can be progressively reduces the ratio of the primary energy of input, strengthen the ratio of regenerative resource, reduce CO ₂Discharging, realize the low-carbon (LC) utilization.
