Problems solved by technology

[0003] At present, the typical business with the characteristics of electric power big data, such as the electricity consumption information collection system, has a large base of electric power users and a huge amount of data generated every day. The accuracy and reliability are reduced, and the space occupied by the power data is increased; and the increasingly large power big data mass information causes the business system to respond slowly in the statistical analysis business, and the user waits for a long time.

Embodiment 1

[0035] Such as figure 1 Shown is the embodiment of scada quasi-real-time data storage method of the present invention, comprises the following steps:

[0036]S1. The scada server obtains and adjusts real-time power signals, and converts the adjusted real-time power signals to obtain real-time power data;

[0037] S2. Logically process the real-time power data in step S1 to remove interference data, and calculate the deviation between the remaining real-time power data and the standard value; if the deviation is within the preset threshold range, mark the corresponding real-time power data as the first category data; otherwise, marked as the second type of data;

[0038] S3. Calculate the average value of the first type of data in step S2 to obtain effective real-time power data, and transmit the effective real-time power data to the data storage module; analyze the reason for the abnormality of the second type of data in step S2, and display it on the display screen superior...

Embodiment 2

[0045] Such as figure 2 Shown is the embodiment of scada quasi-real-time data storage system of the present invention, comprises scada server, signal conditioning module, data storage module and cloud disk:

[0046] The scada server communicates with the signal conditioning module and the data storage module to collect real-time power signals, convert the real-time power signals into single-ended real-time power signals, and convert the conditioned real-time power signals into real-time power data;

[0047] The signal conditioning module is connected to the scada server for two-way communication, which is used to condition single-ended real-time power signals;

[0048] The input end of the data storage module is connected to the scada server, and the output end is connected to the cloud disk; it is used to store effective real-time power data;

[0049] The cloud disk is connected to the data storage module and is used to store the full data cache queue.

[0050] Among them,...

Abstract

The invention relates to the technical field of power big data storage, in particular to an scada quasi-real-time data storage method and system. Collected real-time power signals are subjected to anoptimization policy of conditioning and interference wave filtering, so that the accuracy and reliability of corresponding signals of power data are improved; effective power data is regularly storedand timely transferred to a cloud disk, so that the burden of a business system is reduced, the response speed of the business system is increased, and data expansion and analysis functions can be better finished; massive power data can be collected, stored and processed, so that power operation and maintenance personnel can better know industry dynamics; and in an operation process, an efficientquery function is provided, so that retrieval can be quickly finished while a data amount is rapidly increased. By marking the real-time power data, the effective real-time power data with relativelyhigh accuracy and reliability can be obtained; and display can be performed by a display screen, so that a user can timely know faults causing abnormal data.

Description

technical field [0001] The present invention relates to the technical field of electric power big data storage, and more specifically, to a scada quasi-real-time data storage method and system. Background technique [0002] The scada system is the most widely used in the power system, and the technology development is the most mature. As the most important subsystem of the energy management system (EMS system), it has the advantages of complete information, improved efficiency, correct control of system operating status, faster decision-making, and quick diagnosis of system fault status. It has become an indispensable part of power dispatching. missing tools. Quasi-real-time data, mainly dispatching automation system, power grid wide-area monitoring system, electricity collection, lightning monitoring data, fault recording data, microcomputer protection, status monitoring and other data directly related to the operation of the smart grid. The characteristics of this type of...
