Transformer area data minute-level same-frequency acquisition method and system based on type-II concentrator

Abstract

The invention discloses a transformer area data minute-level same-frequency acquisition method and system based on a type-II concentrator. A transformer area acquires electric meter data through the type-II concentrator, and the concentrator is provided with a minute-level communication protocol to realize minute-level same-frequency acquisition of the electric meter data. According to the system,the communication protocol of the concentrator is expanded, a minute-level acquisition scheme is correspondingly configured, minute-level data acquisition is realized, the power consumption information acquisition frequency is increased, and a new acquisition mechanism is designed for solving the problem that partial acquisition data cannot be effectively acquired possibly caused by an original real-time cyclic acquisition mechanism in a minute-level acquisition task. The problem is effectively solved. According to the system, a good basis is provided for deep power utilization characteristicanalysis, power utilization expectation evaluation, power utilization potential mining, power utilization demand adaptation and other power utilization service quality improvement work of the power distribution network transformer area.

Description

technical field [0001] The invention belongs to the field of electric power technology, relates to the collection of on-site data in a distribution network, and is a method and system for collecting station area data at the same frequency at the minute level based on a type II concentrator. [0002] technical background [0003] With the development of power technology, the related technologies of the ubiquitous power Internet of Things are developing day by day. In order to meet the higher requirements of the ubiquitous power Internet of Things construction on the distribution network-related information collection system, it has become an inevitable trend to comprehensively improve the operation and control of the distribution network cloud, management terminal, edge terminal and terminal. At present, in the power data collection scheme of distribution terminal, there are Type II concentrator + 485 meter, Type I concentrator + carrier meter, Type I concentrator + Type I col...
