Real-time information acquisition system suitable for large-scale new energy grid connection

Abstract

The invention discloses a real-time information acquisition system suitable for large-scale new energy grid connection. The system comprises a data aggregation unit, a data check unit and a data monitoring unit. The data aggregation unit comprises a first data aggregation unit, a second data aggregation unit, a third data aggregation unit and a fourth data aggregation unit; management data is transmitted between the first data aggregation unit and the second data aggregation unit; real-time and prediction data is transmitted between the third data aggregation unit and the fourth data aggregation unit; the second data aggregation unit is also connected with the fourth data aggregation unit to synchronously manage the data; the data checking unit is connected with the second data aggregationunit and the fourth data aggregation unit, and data checking is performed according to a preset rule; and the data monitoring unit is connected with the fourth data aggregation unit and performs datamonitoring according to the preset rule. In the invention, whole-network new energy data access can be realized, a whole-network new energy power generation condition can be monitored more comprehensively, and service support requirements of regional dispatching service new energy consumption auxiliary analysis, post evaluation and the like are met.

Description

technical field [0001] The invention belongs to the technical field of a data management platform of a smart grid dispatching system, and in particular relates to a real-time information collection system adapted to large-scale new energy grid connection. Background technique [0002] With the rapid development of new energy stations in recent years, the existing new energy monitoring information (output, power generation, etc.) can no longer meet the needs of new energy operation monitoring and refined consumption of the whole network, and there is a lack of new energy access monitoring , Network-related information monitoring, regional power generation and wind and solar curtailment monitoring and other global monitoring information, and the display methods are not rich enough, lacking the intuitive visualization of cross-regional channel transmission capacity and global consumption. [0003] In addition, in order to monitor in real time the new energy data of various prov...

AI Technical Summary

Problems solved by technology

[0008] (1) The new energy data connected to the sub-center is only limited to 220 / 330KV collection stations, which cannot meet the needs of new energy operation monitoring for the whole network

[0009] (2) The data monitoring based on the new energy of the collection station only monitors and analyzes the output and power generation, which can no longer meet the needs of the new energy operation monitoring and refined consumption of the whole network

[0010] (3) There is no verification of the rationality and correctness of the access data, which may lead to errors in statistical analysis results
