Embodiment Construction

[0023] In order to solve the problems of high operation and maintenance costs and low collection frequency of the current electricity information collection system, the present invention upgrades concentrators, collectors, and HPLC software and hardware in the station area based on DL / T 645 and Q / GDW 1376.2 protocols. A system and method suitable for minute-level co-frequency acquisition of station area data is given. The minute-level communication protocol of the present invention is based on the extension of DL / T 645 and Q / GDW 1376.2 protocols, and correspondingly expands the storage space of the collector according to the extended protocol; The expansion of DL / T 645 is: based on the DL / T 645 protocol, realize the communication interface that supports minute-level collection, expand the data identification of the 645 message, and make it collect voltage, phase current and Multiple data items including active power; Q / GDW1376.2 involves the communication of the concentrator. I...

Abstract

The invention relates to a minute-level same-frequency acquisition method and system for transformer area data. A transformer area power utilization acquisition mode comprises 1) an I-type concentrator, an I-type collector and an RS485 electric meter, and 2) an I-type concentrator, an II-type collector and an RS485 electric meter. The concentrator and the collector are each configured with a minute-level communication protocol to realize minute-level same-frequency collection of electric meter data. The communication protocol of the concentrator and the collector is expanded, a minute-level collection scheme is correspondingly configured, minute-level data collection is achieved, the power utilization information collection frequency is improved, and a good basis is provided for deep powerutilization characteristic analysis, power utilization expectation evaluation, power utilization potential mining, power utilization demand adaptation and other power utilization service quality improvement work of a power distribution network transformer area.

Description

technical field [0001] The invention belongs to the technical field of electric power, relates to the collection of on-site data in a power distribution network, and is a minute-level and same-frequency collection method and system for station area data. [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, the distribution network power information collection system is mainly realized by the following technology and equipment architecture: [0004] 1. Type II concentrator + 485 meter, Type I concentrator + carrier...
