A smart substation panoramic data center

Abstract

A panoramic data centre of an intelligent substation is composed of a data storage module, an external communication service module and a data collection module, wherein real-time data inside the intelligent substation are collected through the data collection module and uploaded to the data storage module; the data storage module is used for storing the uploaded real-time data and creating unified information models for data storage, primary equipment and secondary equipment; the external communication service module is connected with the data storage module and provides data output services for other substations and main dispatching stations in an information service standardized mode. The panoramic data centre aims to solve the problems that as for data of traditional substations, information among station level subsystems is isolated mutually, the station level subsystems are not in communication with one another, and data are redundant and repetitive; non-shielded data uploading of the traditional substations causes an exponential increase of the uploaded data volume, and therefore large processing pressure on a main station system is caused.

Description

technical field [0001] The invention belongs to the field of power system automation, in particular realizes the organization and service of multi-specialty and multi-dimensional data in an integrated monitoring system of an intelligent substation. Background technique [0002] The substation needs to provide unified, concise and accurate data support for the safe operation of the power grid. As a key node of power transmission and information collection, the comprehensiveness and integrity of its data is the information basis for realizing the smart grid. [0003] The main station of the substation mainly provides two types of data for the power grid dispatching system, one is real-time data, including the traditional "four remote" and other steady-state data, which is mainly used for the operation monitoring of the SCADA / EMS system; the dynamic data is based on the synchronous sampling data of the PMU. Mainly, it is used in advanced applications such as dispatching dynamic...

Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the information between the sub-systems of the station control layer where the traditional substation data exists is isolated from each other, do not communicate with each other, and the collected data is redundant and repeated, and the data uploaded without shielding in the traditional substation causes the data to be sent The volume increases exponentially, which causes a greater processing pressure on the main station system
