Power grid sub-region full-caliber load calculation method and system

Abstract

The invention discloses a power grid sub-region full-caliber load calculation method and system. The method comprises the following steps that the area range information of a designated area of a useris acquired, and the designated area is divided into sub regions on a graphic server; the user load data of 35 kilovolt or below of the sub regions is obtained from the sub regions through an IDP interface; or the user load data of 35 kilovolt or above of the sub regions is obtained from the sub regions through reading PMS2.0 according to the topological calculation; and the real-time load of thesub regions is calculated according to the obtained user load data. The method has the advantages that the system is based on a PMS2.0 power grid net rack topology and integrates the IDP equipment load and current data; loads are distributed to all the regions through the outgoing line percentage of a power station, and the load of the power station is acquired through the IDP interface, the full-caliber load of each sub-region of the designated area is calculated, and full-caliber load data is provided for the smart city energy cloud platform, so that the information of the designated area range and the geographic range of each sub-region can be maintained on a map.

Description

technical field [0001] The invention relates to the field of electric power system and its automation, in particular to a method and system for calculating the full-caliber load of a power grid sub-area. Background technique [0002] With the continuous growth of the power system, the number of users involved in the power grid is increasing, and the distribution network is directly connected with the power supply users, which is an important part of the power system. In order to facilitate daily energy scheduling, Shanghai Pudong Power Supply Company has developed a smart city energy cloud platform. The smart city energy cloud platform expands the intelligent analysis of abnormal power consumption of a single customer to the whole industry and the whole region from point to surface, so that the government's industry change information collection is more direct, timely and perfect. [0003] The smart city energy cloud platform is a comprehensive open platform built by Pudong...

Problems solved by technology

[0004] Among them, the prediction and calculation of the full-caliber load in each sub-region of the power grid is an important part of the smart city energy cloud platform planning. Due to the corresponding relationship between IDP (massive historical real-time data management platform) equipment and PMS2.0, the load obtained through IDP equipment, etc. The data may not correspond to the outgoing equipment and the data is inaccurate, and the later verification and maintenance workload is heavy, so there is an urgent need for a full-caliber load calculation method and system in the sub-region of the power grid to accurately determine the relevant data of the full-caliber load in the sub-region of the power grid
