The equipment operation parameter of receipts, and the big data statistical analysis module 103 is to can be by equipment operation parameter and the water process sense
It is for statistical analysis to survey parameter, to analyze the relevance of all devices operating parameters, and again by the statistical analysis knot after analysis
Fruit is stored in data collection storage database module 102.
And analysis mode used in the big data statistical analysis module 103 be parameter trend analysis, parameter alternate analysis,
The fundamental analyses functions such as parameter association analysis can more accumulate by long-term big data gradually form an energy saving expert system later
System, and further provide for investing energy saving target by being formed by energy saving expert system and repair/update decision recommendation, precognition guarantor
Support the associated specialists suggestions such as maintenance suggestion, optimum operation Optimizing Suggestions.
Wherein energy conservation standard adjustment module 104 is with the statistic analysis result and a water process discharge standard number after analysis
According to, carry out in the case where judging to make the water process sensor parameter to be held in minimum standard, how to come set device operating
Parameter, therefore set all equipment operation parameters are then stored as a device energy conservation performance standard value after judging, therefore being capable of foundation
The device energy conservation performance standard value is adjusted the equipment operation parameter of different external equipments.
Wherein the energy baseline, which establishes module 105, to operate function in the single machine of a period of time operating for different external equipments
Rate is noted down, and by the single machine running power of History Log carry out it is average obtain single machine operating mean power, and by single machine
Operating mean power is multiplied by the same day running hours of different external equipments, then can obtain the energy baseline of different external equipments
Value.
And the energy baseline that the present invention is mentioned refers to the quantization reference line as energy performance benchmark, is come with water process
It says, energy baseline refers to the power consumption electromechanical facility 212 for external equipment 21 out of the ordinary in sewage treatment plant or clean water treatment factory
It is monitored in advance, and when each energy saving target (external equipment 21) daily run based on sewage treatment plant or clean water treatment factory
Between it is indefinite, depend on the factors such as same day sewage quantity, water quality, discharge index, weather and make real-time monitoring.
Under the premise of more need to meeting sewage plant operating condition due to energy conserving system running, single machine operates function before being improved with energy conservation
Rate KW value uploads single machine running power KW value after the improvement recorded as energy baseline, then foundation cloud intelligent platform 1 per minute
And the related duration of runs is to calculate daily energy-saving efficiency KWh value.
Wherein the electric energy calculates and comparison module 106 is can adjust energy baseline value from different external equipments 21
The single machine running power accumulated after whole is compared to produce an energy-saving benefit data adjusted, and the billing management module
107 can set out a Freight Basis, and wherein the Freight Basis can carry out charge adjustment according to different energy-saving benefit data.
Since the billing management module 107 mainly carries out monthly billing energy-saving efficiency, when railway platform electricity electricity price rate and energy conservation
Service contract energy-saving efficiency allocation proportion, and the energy conservation service charging moon bill of the client of output Water condition factory 2, as working as
Moon energy conservation service charge foundation.It will illustrate item by item below:
(1) energy-saving efficiency calculates: measuring & indentification protocol according to the international energy saving performance of IPMVP Option A, both sides survey jointly
Each energy saving target (power consumption electromechanical facility 212) of amount confirmation improves front motor running power KW value, as establishing energy baseline foundation,
Wherein the billing management module 107 mainly records each energy saving target according to data collection storage database module 102 and changes
It deals with problems arising from an accident motor running power KW value, energy saving target (the power consumption electromechanical facility 212) duration of runs, calculating energy saving target, (power consumption is electromechanical
Facility 212) improve front motor running power KWh value and improve after motor running power KWh value, finally the two is subtracted each other as saving
Electric benefit KWh value.
(2) electricity price rate logs in: the platform electricity billing invoice according to 2 client of Water condition factory being set, can be height
Press two-period form electricity price (from peak electricity price, Critical Peak Pricing), high pressure three section tariff (from peak electricity price, half Critical Peak Pricing, Critical Peak Pricing)
Or the charging of average electricity price mode is carried out according to both sides' contract.
(3) allocation proportion is set: according to both service contract energy-saving efficiency allocation proportion, which will
Energy-saving efficiency KWh value calculates the amount of money caused by energy-saving efficiency referring to electricity price rate, then according to allocation proportion output energy conservation service
Of that month billing invoice, and allocation proportion will depend on whole financial plan analysis, such as can distribute 8:2 before break even point, damage
The allocation proportions such as 7:3,6:4,5:5 distribution are gradually switched to by 8:2 distribution after benefit two is flat.
Wherein the chart output module 108 is to can be by equipment operation parameter, water process sensor parameter and/or statistical
