Problems solved by technology

However, due to the long-standing problem of outstanding debts in the company's distribution network history, the overall distribution automation construction is still lagging behind, and it is difficult to adapt to the requirements of today's rapid social and economic development.
The main problems are as follows: the main station system coverage of the power distribution system is low
With the construction of smart distribution network, many places have completed the coverage of distribution automation. Due to the limitation of the number of access terminals for capital investment, in the event of a power failure, some fault information cannot be obtained in time, which delays the repair and recovery time of the fault.

Embodiment Construction

[0032] Abbreviations and key terms of the present invention are defined as follows:

[0033] SIM card: Subscriber Identification Module. Also known as user identification card, smart card.

[0034] Distribution transformer: Distribution transformer refers to a static electrical device that transforms AC voltage and current according to the law of electromagnetic induction in a power distribution system to transmit AC power.

[0035] Star map: By directly connecting substations, feeders, and distribution transformers in a topological relationship, the "three-layer" penetration of substations, 10kV lines and users is realized, and a new power grid graph, namely star map, is formed

[0036] Internet of Things card service access platform: SIM card data information collection platform, which realizes functions such as real-time monitoring, data collection, storage and release of SIM card information.

[0037] MIDMMI: The middle layer service of the power system platform, which p...

Abstract

The invention belongs to the field of power distribution network control and especially relates to a distribution network star map monitoring method based on the SIM card state. The method comprises the following steps: 1) fault study and judgment based on the state of a distribution transformer; and 2) real-time monitoring of the state of the distribution transformer based on star map display. The distribution network star map monitoring method based on the SIM card state solves the problem of blind adjustment, can grasp the charged state of a power distribution network in real time and provides support for safety production and operation maintenance.

Description

technical field [0001] The invention belongs to the field of distribution network regulation and control, and in particular relates to a distribution network star map monitoring method based on the state of a SIM card. Background technique [0002] As of February 2015, the State Grid Corporation of China has completed the construction of distribution automation master station systems for 86 prefecture-level regulatory agencies (accounting for 27%) and 213 county-level regulatory agencies (accounting for 15.90%). Distribution automation has made considerable progress, and the level of automation in pilot areas has been greatly improved. However, due to the long-term outstanding debts of the company's distribution network, the overall distribution automation construction is still lagging behind, and it is difficult to meet the requirements of the rapid social and economic development today. There are mainly the following problems: the coverage rate of the main station system ...
