A power distribution network operation aid decision analysis system and an application method thereof

Abstract

The invention discloses a power distribution network operation aid decision analysis system and an application method thereof. The system comprises a data layer used for classifying and storing acquired external data; the platform layer is used for classifying the data stored in the data layer and building an operation module according to the type; the application layer is used for classifying thestored data according to the operation modules and the data layer built by the platform layer; risk analysis is carried out on the power distribution network and an optimization scheme is provided, the display module is also used for displaying result information of each operation module; the difference characteristic of the urban power distribution network is fully considered from the overall architecture design to the specific service function design, the power distribution network is directly operated, maintained and overhauled, corresponding measures are put forward in a targeted mode forintelligent auxiliary decision analysis of the power distribution network, and the probability of power distribution network faults and risks is reduced.

Description

technical field [0001] The invention relates to the technical field of urban distribution network operation simulation, in particular to an auxiliary decision-making analysis system for distribution network operation and an application method thereof. Background technique [0002] With the popularization and application of application systems such as distribution automation and power consumption information collection, massive heterogeneous, high-dimensional and multi-state data are generated in the distribution network with exponential growth. Due to the late start of distribution network informatization, poor data quality, data types, and data perfection, it is necessary to conduct research and analysis on distribution network-related information systems, and conduct data prediction based on existing and reliable distribution network data information. deal with. How to flexibly apply the general method of big data in the information field to the big data analysis of distr...

Problems solved by technology

[0004] A large number of distributed power sources, micro-grids, large-capacity chargers, and energy storage systems are connected to the distribution network, making the distribution network transform from a traditional passive distribution network to a more active active distribution network. Due to the characteristics of complexity, flexible operation mode, two-way changeable power flow, and uncertain output, distribution network fault characteristics are quite different from traditional distribution network. The weak characteristics and high-frequency transient characteristics of distribution network faults are becoming more and more obvious. The difficulty of fault diagnosis and treatment of the power grid increases, which reduces the performance of the existing relay protection and fault diagnosis of the distribution network, and is prone to misoperation and misjudgment, which seriously threatens the safe operation of the distribution network.
