Centre grade data server, reception real time energy consumption data storage, carry out centralized energy measurement statistical management by centre grade data server to all stations of track traffic levels (comprising electric substation) and energy consumption is comprehensively analyzed.
1, centralized metering:
The status of energy consumption that will correctly reflect circuit or network must be based upon on the basis of energy consumption accurate-metering.Each rail line of District of Shanghai is all provided with total measuring apparatus to electric system at present, but these measuring apparatus are generally all located at main transformer station, and traction substation and stepdown substation measuring apparatus are also perfect not to the utmost.The collection of these continuous datas mainly relies on manual method, and real-time and accuracy are all not ideal enough, often causes raw statistical data to make mistakes, and affects energy consumption analysis result.It is careful not enough to also have the classification metering setting of the each professional system in station, and the concrete reason analysis changing for circuit energy consumption is like this more difficult, and being also just difficult to suits the remedy to the case takes correct conservation measures.
Therefore, in the time of circuit electric power system metering design, take into full account that the actual demand of energy consumption measure is very important, the newly-built circuit in Shanghai has clearly proposed the specific requirement that metering system arranges, can, by gauge table and intelligent instrument are rationally set, in electric integrated supervisory system, realize centralized classification, classification and real-time remote auto function of measuring.
2, centralized energy consumption analysis
Urban track traffic is the comprehensive systems engineering in conjunction with each specialties such as civil engineering work, vehicle, signal, communication, power supply, ring control and automatic controls, a large amount of new technologies and new equipment have been applied in modern urban track traffic especially, mainly contain following characteristics aspect energy resource consumption:
The first, all kinds of major equipments that track traffic is used, by driven by power, only have a small amount of utility appliance to consume coal gas, fuel oil equal energy source, also consume in addition a small amount of water resource in operation process.Therefore, the main energy sources of track traffic is electric power, and this is also energy-conservation major control object.
The second, energy consumption peak valley is obvious:
Track traffic is all being runed throughout the year as public transport, the time of general operation every day is probably from 5:00 AM left and right to the late into the night more than 11, during runing, power consumption will account for more than 90%, after operation finishes, there is the static operation of some maintenance of equipment, debugging work and equipment component, also have certain power consumption.
In addition, along with global warming, some Shelter in South China Cities summer high temperature times such as Shanghai are more and more longer, and the time of track traffic air conditioning condition operation was generally taken about 5～6 months, and interior power consumption is very large during this period of time.
Three, train traction energy consumption proportion is larger:
According to historical data statistics, on the rail line of operation condition comparative maturity, the power consumption proportion for train traction exceedes 50% under normal circumstances, and the power consumption such as other all kinds of power and lightings are less than the half of total amount.
Four, various circuit energy consumption comparability deficiencies:
Because there are varied forms such as underground, overhead, ground, ditch at rail line and station, article one, line may be also that various ways combines, the train moving on the line, each device systems of an outfit at station etc. are also each variant, volume of passenger traffic size is also different, even if also may build up hardly essentially identical 2 circuits of various conditions in same city.Therefore, the energy resource consumption between different circuits and energy-saving effect are carried out acquiring a certain degree of difficulty than commenting.
According to the feature of above track traffic energy consumption, the energy consumption of native system can be from different angle analysis, substantially have following several:
The first, with passenger person-kilometres hooks, unit is: kilowatt hour/passenger-kilometer, with the ratio of the annual total power consumption of single line (or network) and passenger person-kilometres.Similarly can amplify classification energy consumption index, as traction energy consumption index, with the ratio of the annual trailer system power consumption of single line (or network) and passenger person-kilometres.
The second, with volume of the flow of passengers hook, unit is: kilowatt hour/person-time, with the ratio of the annual total power consumption of single line (or network) and the volume of the flow of passengers.Also can as described in the first, do similar amplification.
The third, with capacity hook, unit is: kilowatt hour/truck kilometer, the i.e. ratio with train total kilometres (or runing mileage) with the annual total power consumption of single line (or network).Also can as described in the first, do similar amplification.
The third, with ticketing service income hook, unit is: kilowatt hour/unit, the ratio of taking in the annual total power consumption of single line (or network) and ticketing service.Also can as described in the first, do similar amplification.
Because urban track traffic is made up of multiple professional systems, energy consumption index can also be classified by system.These energy consumption indexs have embodied respectively the relation of various aspects relevant to urban track traffic and energy consumption, can grasp actual conditions and the variation tendency of energy consumption by statistic of classification and calculating.
