Problems solved by technology

Most of the existing load forecasting methods use the power data center to directly predict the load of busbars, transformers and other power equipment by analyzing their historical load data and weather factors. Due to the limited power equipment in the station area, thus The working method of the existing power data center has the problem of single input data

Embodiment 1

[0044] like figure 2 As shown, a working method of a power data center includes the following steps:

[0045] Step S110: reading stored historical data in response to a trigger command;

[0046] The power data center, also known as the power grid data center, is a unified platform for company-level power big data resources, data product display, sharing, collaboration, communication, transactions, and capability sharing services. The power data center stores standardized and large amounts of history Business data, algorithm models, and computing power provide effective support for the power forecasting model. This application uses the standardized SQL statement (SQL statement, that is, structured query language, which is a database query and programming language used to access data and query, update and manage relational database systems) to extract the required The historical data and related information of the region form a data source table.

[0047] Since the SQL comma...

Embodiment 2

[0072] The working method of the power data middle station is described in the first embodiment. Further, the present application may further include the following steps:

[0073] Use historical data to revise the combined forecasting model to obtain an optimized forecasting model.

[0074] The present invention automatically compares the prediction result of the combined forecasting model with the real data of monthly electricity in the power data center, and continuously adjusts the parameters of the combined forecasting model until the result deviation of the combined forecasting model is within a preset range.

[0075] There is a large amount of real and effective monthly power related data stored in the power data center. By comparing the forecast results of the combined forecasting model with the historical data of the real monthly power, the deviation of the forecast results is obtained. The error is analyzed, and model feedback and verification optimization are carried...

Abstract

The invention relates to a power data control panel and a working method thereof, and the working method of the power data control panel comprises the following steps: reading stored historical data in response to a trigger command; inputting the read historical data into a pre-constructed combined prediction model for analysis to obtain an analysis result; and outputting an analysis result. By adopting the technical scheme, the combined prediction model constructed according to the related data provides effective business data, an algorithm model and operational capability support for the power data control panel.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to a power data in a power station and a working method thereof. Background technique [0002] The station area in the power system refers to the power supply range or area of ​​one or more transformers, and the power data center controls and allocates the transformers in the power supply range or area. In the power system control, the configuration and management of the power data center is an important aspect of completing the work of the power system. [0003] Among them, accurate short-term power load forecasting is one of the important workflows in the power data center control. Most of the existing load forecasting methods use the power data center to directly predict the load of busbars, transformers and other power equipment by analyzing their historical load data and weather factors. Due to the limited power equipment in the station area, thus Therefore, there is a p...
