Description
Technical field
The present invention relates to energy-saving of motor system emission reduction fields, more particularly to a kind of real-time dynamic energy-saving of motor system amount core
Calculation method and monitoring system.
Background technology
Electric system refers to by drive motor, transmission mechanism, control (speed governing) device, dragged device and system functional group
The totality that part is formed.Electric energy dress is changed to mechanical energy by system by motor, then various by the acting realization of dragged device
Function.
The electricity consumption of China's electric system accounts for about the 60% of China's total electricity consumption at present, wherein wind turbine, pump class, compressor and
The electricity consumption of air conditioner refrigerating device accounts for the 10.4% of national electricity consumption respectively, and 20.9%, 9.4%, 6%.Industrial circle electric system
Electricity consumption accounts for about the total electricity consumption total amount 75% of national industry, however China's electric system efficiency is lower 10-30% than developed country, quite
It is horizontal in the international 70-80 ages in 20th century.
Energy-saving of motor system has become industrial energy saving key.The development trend of the following motor must be energy-efficient, improve
Efficiency saves resource, reduces environmental pollution.Country pays much attention to energy-saving of motor system, early in 2008 just by energy-saving of motor system
One of national ten big energy conservation projects are included in, efficient, ultra-high efficient motor application civilian-oriented project is included in again within 2009, put into effect within 2015
《National motor efficiency promotes plan》Deng, using energy-saving efficient motor and energy-saving of motor system transformation be national requirements, simultaneously
Huge amount of energy saving also very attracts enterprise to be transformed existing motor.Meanwhile in " 13 plan " energy-saving and emission-reduction planning
Also it mentions and third party, Energy Service Company is encouraged to carry out reducing energy consumption project.
China's motor market mainstream series is：JO2 series, Y-series, Y2 series, YX series, efficiency is far away from magneto
And the efficiency of the products such as the high efficiency motors such as reluctance motor, ultra-high efficient motor, and the utilization rate of this kind of high efficiency motor is no more than 15%,
It is learnt from investigation situation, enterprise and with understanding this kind of technology per family, but they also indicate that current existing system or draft newly
Whether the system built needs this kind of high efficiency motor, the problems such as whether capable of obtaining satisfied amount of energy saving using high efficiency motor.Thus
As it can be seen that although the market potential of reducing energy consumption at present or newly-built high efficiency motor system is very huge, high efficiency motor system is pushed
And reducing energy consumption is extremely important, but electric system user more importantly how to be allowed accurately to understand the energy-saving potential of current system
And accurate accounting system amount of energy saving.
Currently, the research direction of the amount of energy saving calculating and efficiency ratification method for electric system has benchmark unit consumption method of comparison
(product/output value), accumulative and method.At this stage, unit consumption method of comparison on the basis of domestic common amount of energy saving computational methods, this method point
For unit consumption of product method of comparison and output value unit consumption method of comparison, technical method is similar.Its expression formula is：
Δ E=(e(t+Δt)-et)Q
Wherein, e(t+Δt)It indicates to carry out the energy consumption of unit product after certain technology or measures to reform, etIndicate business unit's production
Product energy consumption, Δ t indicate that measuring and calculating time, Q indicate amount of product throughput/enterprise's output value.
Accumulation and method are applied relatively broad in American-European countries, are a kind of methods in statistics, are several samples
The sum of the accumulation of difference between value and some preset value.A certain power-saving technology and measure are chosen before implementation in the fixed cycle
Energy consumption and product yield record as data sample and generate energy consumption and Yield mapping (E-P), with one-variable linear regression mould
The correlation theory and method of type can acquire correlation between the two before and after power-saving technology is implemented.
E=mP+e
In formula, the energy energy-output ratio that E is indicated, what P was indicated is the yield of certain product of enterprise, and the meaning that m is represented is production
Coefficient of elasticity between product yield and energy input, namely often increase the product yield of a unit, the quantity of energy of required input, e
It indicates in process of producing product and the yield of product does not have the consumption of the energy of fixed relationship, this is an additional shift
Value.
Technical measures method, structural measure method are based on benchmark unit consumption method of comparison and derive.Report is all made of in comparison procedure
The corresponding index value of amount of energy saving before and after phase is made difference and is obtained.
For benchmark unit consumption method of comparison (product/output value), technical measures method, structural measure method, although method is being answered
With relatively simple easy in operating process, but before and after implementing there is technical measures, once product yield changes greatly, weighing apparatus
Magnitude will be inaccurate defect.In addition, being unfavorable for the watershed management of enterprise implement project construction, project construction may be caused
High energy consumption, high pollution and low-level duplicate construction.Such methods do not adapt to and receive the dynamical system of many factors influence.Also
Have, for dynamic electric system, the report period is difficult to using unit consumption method and base period benchmark is completely the same, leads to result of calculation not
Accurately.
For accumulation and method, due to there is no disappearing for the energy of fixed relationship with the yield of product in process of producing product
Consumption is an additional shift value, can not accurately be measured, and coefficient of elasticity fully relies on the acquisition of linear regression model (LRM) match value, obtains
As a result system energy efficiency situation cannot be accurately reflected.
The product yield used in above-mentioned calculating refers to qualified products, does not include substandard products and waste product, but energy-output ratio is answered
The energy quantity consumed including waste product, substandard products.So calculating existing defects.
Other than the above problem, for dynamic electric system, the major limitation of above-mentioned amount of energy saving computational methods is can not
The whole energy management level of enterprise is embodied in result of calculation, technical measures method calculates amount of energy saving and is only limited to pass through power-saving technology
Transformation improves the efficiency of energy utilization of production process and equipment, reduces energy consumption and realize energy conservation.Without including expanding
The energy-saving effect that production capacity, the approach such as adjust the product mix generate.In terms of these aspects may be to reducing enterprise energy consumption total amount
Contribution is very big, but is not reflected in technical measures method calculating process；Second is that existing technical measures amount of energy saving calculating side
Still it cannot in time, dynamically cover the full content of industry energy conservation technological transformation in method, it is difficult to the practical amount of energy saving of reflection.
