Description
Technical field
The invention belongs to GIS for electric power technical field, and in particular to be a kind of power scheduling based on GIS
Graphical data methods of exhibiting.
Background technology
With carrying out in a deep going way for national grid informationization work, power network GIS platform and SCADA dispatching system are in respective field
The effect of performance is increasing, but all there is show the drawbacks of not directly perceived enough for scheduling data all the time.Electric power is adjusted at present
The exhibition method of degrees of data mainly has form or netted contact diagram form etc., and the former can only check and statistics, both
The annexation being unable between presentation device and circuit, geographical position and the surrounding environment at their actual places can not be shown,
Although and the latter can be between presentation device and circuit annexation, can not show they it is actual where geographical position and
Surrounding environment.Work so to scheduling related personnel all brings many inconvenience, it is necessary to repeatedly especially when pinpointing the problems
The information such as form, netted communication chart, map are compareed, both wasting manpower and material resources, wasted time again.Therefore, in order to better improve
The efficiency of related work is, it is necessary to which a kind of method can show scheduling data, equipment and connection pass simultaneously on an interface
The information such as system, actual geographic location and surrounding environment.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of information in power dispatching center figure based on GIS
Shape methods of exhibiting.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of information in power dispatching center graphical representation method based on GIS, including step are as follows：

City net, overhead transmission line, Xingtai Power Supply Company, 220kV Milky Way station, 116812117079753143, Hebei Milky Way station/110kV.
Its circuit of 1 line of steel 176,10kV, 100A, 10.04kV, 47.35A, closure, closure, 10 days 14 October in 2014:17:35-10kV
The protection of terminal short-circuit breaker open operation occurs for its outlet of 1 line I sections bus of steel 176)
2. analysis calculating is carried out to obtained scheduling data：By it is above-mentioned 1. in correlated variables, each city can be calculated
Net 10kV circuits nominal load, real time load, number of manually operating a switch, fault trip number, and the net 10kV outlets of transformer city
Real-time total current, real-time total load, the real-time total current of prefectures and cities' city net 10kV outlets, real-time total load, formula are as follows：
Nominal load (rated capacity)=rated current × rated voltage is (such as：176 days line nominal loads of steel 1 of the Milky Way=
10kV × 100A=1000kVA=1MW)
Real time load (real time capacity)=real-time current × real-time voltage is (such as：176 days line real time loads of steel 1 of the Milky Way=
10.04kV × 47.35A=475.395kVA=0.475395MW)
Load factor=real time capacity ÷ rated capacities × 100%=real-time current ÷ rated current × 100% is (such as：The Milky Way
The 176 days line real time load of steel 1=47.35A ÷ 100A × 100%=47.35%)
The transformer city net real-time total current=∑ of 10kV outlets (real-time current occurs in each 10kV of the transformer)
The transformer city net real-time total load=∑ of 10kV outlets (real time load occurs in each 10kV of the transformer)
Districts and cities' city net real-time total current=∑ of 10kV outlets (real-time current occurs in each 10kV of the districts and cities)
Districts and cities' city net real-time total load=∑ of 10kV outlets (real time load occurs in each 10kV of the districts and cities)
Artificial number of operating a switch counts to obtain with fault trip number according to the closed and disconnected situation of switch and disconnecting link, whenever
On off state previous moment state is closure, and when current time state is gone off, record once switches off；Likewise,
When disconnecting link state previous moment state is closure, and current time state is gone off, records a disconnecting link and disconnect.Opening
Close and be disconnected in the time of switch closure, if disconnecting link does not disconnect, be judged as fault trip, it is on the contrary then be judged as artificially drawing
Lock.
