Power distribution network simulation research and analysis system and method based on network-wide data

Abstract

The invention specifically discloses a power distribution network simulation research and analysis system and method based on network-wide data. The system comprises a three-layer structure: a data layer, a platform layer and an application layer. The data layer mainly collects basic and operation data of a distribution network; the platform layer mainly gathers and summarizes various data of the distribution network and provides corresponding services to the application layer; and the application layer mainly, under the support of the platform layer and based on network-wide equipment and operation data, carries out a series of correlated application researches related to the power distribution network on scientific modeling, load flow calculation, fault analysis, closed-loop calculation, network reconstruction and self-healing simulation modules of the power distribution network comprising a lot of distributed generation, so as to realize comprehensive digital simulation of the power distribution network, and to provide decision reference for the construction and operation of the power distribution network.

Description

technical field [0001] The invention relates to a power system simulation research system, in particular to a distribution network simulation research analysis system and method based on the whole network data. Background technique [0002] Among many links in the power system, the distribution network directly faces users and is the core of the future smart grid, which is related to whether the intelligentization of my country's power grid can be successfully realized. At present, although my country is vigorously promoting and implementing distribution automation projects, due to the uneven level of distribution equipment and distribution automation in various regions of our country, it is far from reaching the requirements of smart distribution networks to encourage users to participate in grid interaction and support. The goal of new energy power generation and support for demand side management is not yet able to achieve the optimal operation and self-healing control of ...

Problems solved by technology

However, at present, there are few simulation systems specifically for distribution networks, and the simulation research on distribution networks mostly stays at the stage of theoretical demonstration, resulting in unreasonable planning and layout of some distribution networks and equipment selection, high line loss rate and failure rate, and difficult Adapting to many unfavorable factors such as distributed power access, it is difficult to meet the actual needs, cannot exert its maximum effectiveness, and has a rather adverse impact on social and economic development
