It is based on topological structure of electric in area power grid theory nework losses proposed by the present invention and intelligently generate network loss Statistical Area
The method in domain describes in detail as follows in conjunction with the embodiments:
For the power grid enterprises of management electrical energy transportation, for example each province, city-level grid company are although electrical network is physically whole
Body links together, but the electrical network administered of each grid company is a part for whole electrical network, or carries out according to region
Divide, or divided according to electric pressure, all define bright between the grid equipment scope that each grid company is administered
True boundary position.Equally, the grid equipment scope that power grid enterprises and electricity power enterprise are managed also has clear and definite border.Each electrical network
In the active power loss electricity of statistical computation electrical network, the equipment in statistical computation our company compass of competency is in transmission electric energy for company
Shi Yinqi network loss.Meanwhile, at present in the Operation of Electric Systems of China, area and County Power Grid are all run using radiation mode,
For area power grid, there is between its 220kV transformer station circuit and interconnect, and 110kV transformer station is only become with higher level 220kV
Power station connects, and does not have circuit to interconnect between 110kV transformer station;To County Power Grid, 35kV transformer station and higher level's 110kV power transformation
Stand connection, or be joined directly together with higher level 220kV transformer station, between 35kV transformer station, do not have circuit to interconnect.This operation
Under mode, from 220kV transformer station high-voltage side bus, define voltage each containing 220kV-110kV-35kV or 220kV-35kV
The radiation of grade transformer substation runs partitioned area.
Fig. 1 gives a typically regional three-level electrical network radiation diagram, the root of radiation power grid be region electrical network 220kV
Main transformer, it passes through medium voltage side winding (110kV) and low-pressure side winding (35kV) connects subordinate ground and adjusts electrical network, and medium voltage side winding connects
110kV bus draw some 110kV circuits, be connected to 110kV transformer station of subordinate, in some cases, 35kV bus also may be used
To draw some 35kV circuits, it is connected to the 35kV transformer station that county of subordinate adjusts electrical network.110kV transformer station can join in general
Put volume three power transformation depressors, wherein pressure is surveyed the 35kV bus some 35kV circuits of extraction that winding connects, is connected to subordinate's 35kV power transformation
Stand.
By analysis above, from the beginning of 220kV main transformer, define the three-level spoke across tri- electric pressures of 220-110-35
Radio net, in this region, 220kV main transformer, 110kV circuit, 110kV main transformer, 35kV circuit and 35kV main transformer are all to produce
The equipment of kwh loss, in carrying out area power grid network loss statistics, not only to consider 220kV main transformer, 110kV circuit and
The loss of 110kV main transformer, in order to improve the accuracy of statistics it is also desirable to consider the damage of 35kV main transformer and 35kV circuit
Consumption.
To sum up, in area power grid network loss statistics, the network loss region of formation is named asAdd network loss statistics equipment it
Afterwards, it is written as
It is in the 220kV transformer of running status, total N platform, be designated as 1,2,3...n;
In 220kV transformer, pressure surveys the connected 110kV circuit being in running status of bus, a total of J platform, is designated as

After determining the armamentarium participating in statistics, on the one hand can be calculated grid company compass of competency of interest
Interior total theoretical network loss, on the other hand can obtain complete network loss distribution, i.e. total network loss Producing reason and composition.This is right
The scheduling decision that grid company formulates reduction network loss is very meaningful, can be ranked up equipment according to network loss size, pass through
Adjustment power system operating mode, reduces the electric network active trend of conveying on high network loss equipment, thus effectively reducing grid net loss.
Simultaneously as the method for operation of electrical network often changes, network loss Statistical AreaIn element with the method for operation
Often change it is impossible to set manually in advance.Therefore in network loss statistical system, need to automatically generate in real time area power grid
Network loss Statistical Area
At present in existing mode, in area power grid, determine that the equipment participating in network loss statistics has only included 220kV and 110kV
The equipment of grade is it is impossible to the 35kV equipment during county is adjusted carries out network loss statistics.Constantly fast-developing with electrical network in recent years, this
Mode has been difficult to meet the requirement of online theory nework losses precision.Power grid structure and equipment are in fast development and change
During change, in order to ensure that powernet theory nework losses can be more accurately it is necessary to expend substantial amounts of manpower to carry out county
Adjust the manual maintenance work in region, it is inaccurate to result in online Losses Analysis result, can not reduce dispatching automation personnel's again
Workload.From the point of view of published document, the method going back neither one system can solve the problem that this problem.
The region of the actual 220kV-110kV-35kV that the present embodiment selects, administration is adjusted with covering in this region
220kV transformer station and 110 transformer stations and county adjust the 35kV transformer station of compass of competency, meet the present invention with regard to area power grid net
Damage the region covering required for statistics.The low-pressure side 35kV bus of wherein 220kV transformer station is connected with the transformer station of 35kV, middle pressure
The low-pressure side 35kV bus that side 110kV bus carries in 110kV transformer station, and this 110kV transformer station is also connected with 35kV's
Transformer station.
