The domination method of described power supply node is: when switchtype is on and off switch or interconnection switch, generates a power supply joint
Point；
The domination method of described load bus is: when switchtype is load branch switch, generates a load bus；
The domination method of described line node is: when switchtype is common block switch, generates a line node；
The domination method of described bus nodes is: topology sheet type is for collectively cover with bus-tie circuit breaker group, two distribution terminals
One when collectively covering a sectionalized single busbar connection switches set with bus-tie circuit breaker group or two distribution terminals, generates a bus joint
Point.
Feeder line topology sheet multiway tree method for building up based on switch syntopy the most according to claim 2, its feature exists
In,
The multiway tree spy that described topology sheet type generates when being Single switch is containing two nodes, and the number of plies is two-layer, saves with one of them
Point is root node, and another node is leaf node；
The multiway tree number of plies that described topology sheet type generates when being same bus-tie circuit breaker group is two-layer, with bus nodes as root node,
All other routes node, load bus or power supply node are leaf node；
Described topology sheet type be two distribution terminals collectively cover one with during bus-tie circuit breaker group generate the multiway tree number of plies be
Two-layer, with bus nodes as root node, All other routes node, load bus or power supply node are leaf node；Each topology sheet
A corresponding multiway tree, two multiway tree median generatrix nodes point to same bus；
Described topology sheet type is the multiway tree layer that two distribution terminals generate when collectively covering a sectionalized single busbar connection switches set
Number is two-layer, and sectionalized busbar is managed jointly by two distribution terminals, and the multiway tree that the topological sheet without bus connection switch generates, with mother
Line node is root node, and All other routes node, load bus, power supply node are leaf node；Topological sheet containing bus connection switch is raw
Two bus nodes will be there are, wherein, with the bus nodes that other kinds node exists direct connection relational in the multiway tree become
For root node, All other routes node, load bus, power supply node and bus nodes are leaf node.
