In topology Identification, first since the bus of high-pressure section.High-pressure section has two buses, any one mother
Line can find another bus by 3 switches, therefore this two buses are judged as 3/2 bus type, and this two mothers
Line sets up a bus group, so as to the interval information of subsequent storage connection branch.
Intermediate pressure section has three buses, and uppermost bus can search branch by a disconnecting link, therefore be judged as
It is other female.Two following buses can search other side by two disconnecting links, therefore be judged as double-bus type, and then this two
Bus sets up a bus group, can store other interval informations so as to subsequent.
Low-pressure section has two buses, this two buses be all unsatisfactory for 3/2 bus type of front, double-bus type and
Other these three Rule of judgment of mother, therefore it is all judged as single parent type, then this two buses respectively individually set up a bus
Group.So far, whole bus types all establish four bus groups it has been determined that having altogether, are 3/2 bus type, double-bus respectively
Type, single busbar type and single busbar type.
Next, carrying out traversal search respectively to this four bus groups to find interval letter all in each bus group
Breath.High-pressure section bus group searches for all branches since any bus in two buses, may search between two column
Every wherein each column interval includes two branches, 3 switches and 6 disconnecting links.Intermediate pressure section bus group is from following two buses
Any bus starts, and searches for all branches, may search for five being spaced, wherein a branch is respectively contained at three intervals, in addition
There is an other female interval to include other female switch, having a mother interval includes bus connection switch.Here the method at mother interval is determined
It is other buses found from a bus search in the same bus group, thereby determines that relevant device is mother interval.Low pressure
There are two part bus groups, and method is similar, can search respective branch interval, and there are one section gaps.Here really
The method for determining section gap is other buses found in other bus groups from a bus search, thereby determines that relevant device is
Section gap.Based on these three the basic wiring of single busbar, double bus scheme and 3/2 bus it can be seen from this analytic process
Bus group be unfolded topology search, can be easy to be handled differently mother interval and section gap.
After the completion of the bus type of four bus groups and its connected interval are all searched for, Substation Bus Arrangement mode is distinguished automatically
