Embodiment Construction

[0035] The invention will be described in detail below in conjunction with specific embodiments.

[0036] A load density optimization calculation method based on electric power big data, including

[0037] Step 1, such as figure 1 As shown, a distributed storage computing platform is established in the Linux system. The source data is in the form of an external data table as the form of data query and reconstruction. Hive is used to complete the access to the external data table, and the data table is converted into a distributed data table through the HOL language. Import the system in the form of a set.

[0038] Distributed storage computing platform, including at least establishing a distributed computing layer and a data storage layer;

[0039] Such as figure 2 As shown, the establishment of a distributed computing layer includes the establishment of an upper-level computing platform based on Spark and a lower-level computing platform based on Hadoop. Tasks, building ...

Abstract

The invention relates to the field of computing load data of a power grid transformer. Especially, the invention relates to a load density optimization calculation method based on large data of electric power. The invention skillfully converts the longitude and latitude coordinates of the vertices of any irregular region by plane transformation, and converts the area calculation problem of the region into the calculation of the polygon area. The invention can calculate the area density of any frame selected area, so that the power supply company can quickly grasp the power generation data at the peak time of the power consumption in the load hot spot area, which is of great significance to the safe operation of the regional power network.

Description

technical field [0001] The invention relates to the calculation field of power grid transformer load data. In particular, it relates to a load density optimization calculation method based on electric power big data. Background technique [0002] With the development of intelligence and informatization of the distribution network, the amount of data generated by the distribution network every day is increasing, and the traditional data processing methods have long been unable to meet the needs of power supply companies for distribution network planning and management. Diverse data structures, complex data relationships, and high real-time data requirements have always been the difficulties in extracting effective information from distribution networks. The application of big data technology to the power industry can efficiently solve the problems caused by the massive data processing and calculation of the distribution network, and can also carry out regionalized and indust...
