The invention discloses a
tower information modeling method for
power transmission lines. The method is characterized in that the
power transmission lines are called lines, two ends of the lines are called breaking points,
transformer substations are called nodes, each
tower is called a sub-node, the lines among the towers are called segments, each sub-node has the attributes of the affiliated unit and geographic position, each sub-segment has the use span attribute, and a dispatching
system can directly acquire the affiliated unit of a fault point and the
tower corresponding to the fault point through the distance between the fault point and a
transformer substation according to the use span information among the towers and timely distribute the fault point to the corresponding unit to perform
processing; the construction of the
power grid power transmission lines is a progressive process, and the power transmission lines and the towers need to be added, modified and deleted at any time during the construction. By the method,
informatization modeling of tower information can be achieved, tower positioning speed and precision can be increased greatly,
system flexibility is enhanced greatly, and power business information interaction is facilitated.
