Power distribution GIS model based distribution network ring network account book automatic generation method

Abstract

The invention discloses a power distribution GIS model based distribution network ring network account book automatic generation method which comprises the following steps of acquiring distribution network line ring network account book information through a power distribution GIS model database, and generating a ring network account book of a distribution network line; acquiring a criterion of adistribution network ring network account book through a power distribution GIS model, and judging the generated distribution network line ring network account book; formulating an automatic updatingrule aiming at current account book data of the ring network account book; and updating data of a current ring network account book in real time according to the formulated automatic updating rule. Byadopting the technical scheme of the invention, a method that a person of a power supply station manually maintains the ring network account book data through a flow is omitted, the workload of the person of a basic-level power supply station is greatly lightened, and the efficiency of a worker of a power grid enterprise is improved.

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
