A method for automatically generating distribution network ledgers based on distribution gis model

Abstract

The invention discloses a method for automatically generating a distribution network ring network ledger based on a power distribution GIS model, which includes obtaining distribution network line ring network ledger information through a power distribution GIS model database, and generating a distribution network ring network ledger; The electrical GIS model obtains the criterion of the ring network account of the distribution network, and judges the ring network account of the generated distribution network line; formulates automatic update rules for the current account data of the ring network account; according to the formulated The rules of automatic update update the data of the current ring network ledger in real time. The technical scheme of the invention eliminates the need for the personnel of the power supply station to manually maintain the data of the ring network ledger through the process, greatly reduces the workload of the personnel of the power supply station at the grassroots level, and improves the efficiency of the staff of the power grid enterprise.

Description

technical field [0001] The invention relates to the technical field of power grid information, in particular to a method for automatically generating distribution network ledgers based on a distribution network GIS model. Background technique [0002] In order to prevent large-scale and long-term power outages caused by the loss of voltage in substations and 10kV buses, the distribution network dispatcher needs to formulate a power supply plan for the distribution network line when the voltage is lost. situation and power transfer capability. At the same time, the planning department also urgently needs to use the ring network ledger information to understand the power transfer capacity of the current distribution network and strengthen the distribution network construction of weak links. [0003] The traditional method of manually formulating the information of the distribution network ring network ledger information based on the distribution network single-line diagram ri...

AI Technical Summary

Problems solved by technology

[0003] The traditional method of manually formulating distribution network ring network ledger information based on the distribution network single-line diagram ring network points has problems such as heavy workload, low efficiency, poor accuracy, and difficulty in ensuring real-time performance.

In addition, a special ring network ledger data management module and process are established to manage the distribution network ring network ledger. The personnel of the power supply station enter the module to update when the ring network ledger changes, which improves work efficiency to a certain extent, but still There is a large maintenance workload, and manual updates cannot keep up with the change speed of the distribution network ring network ledger

[0004] Based on the above analysis, the traditional distribution network ring network ledger acquisition method has problems such as heavy workload, low efficiency, slow update speed and low accuracy.

Traditional methods are difficult to support the needs of power supply enterprises to implement lean management under the environment of power system reform
