Embodiment Construction

[0061] In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

[0062] Embodiments of the invention:

[0063] The voltage level of my country's power distribution system, according to the "Guidelines for Urban Power Grid Planning and Design", 35kV, 66kV, and 110kV are high-voltage power distribution systems, 10kV and 6kV are medium-voltage power distribution systems, and 380V and 220V are low-voltage power distribution systems. The voltage of 220kV and above is the power transmission and transformation system. However, with the continuous expansion of urban power supply capacity and power supply scope, some megacities, such as Beijing and Shanghai, have introduced 220kV voltage into urban areas for power distribution.

[0064] The high-voltage distribution network is characterized by a relatively stable structur...

Abstract

The invention discloses a risk evaluation index system of a multi-dimensional power distribution grid. The risk evaluation index system comprises a high-voltage distribution grid index and a middle-voltage distribution grid index, wherein the high-voltage distribution grid index comprises a high-voltage system layer index and a high-voltage device layer index, and the middle-voltage distribution grid index comprises a middle-voltage system layer index and a middle-voltage device layer index. With the risk evaluation index system for the multi-dimensional power distribution grid, disclosed by the invention, the one-sidedness and the defects of power grid evaluation by a single evaluation mode are avoided, and comprehensive and deep evaluation on the power grid are thoroughly fulfilled in a three-dimensional way; and the risk evaluation index system is conform to engineering practice, the risk existing in the power distribution grid can be fully reflected from macrocosm to microcosmic, a corresponding weak link is recognized, and a corresponding reference and a guidance basis are provided for scheduling operation.

Description

technical field [0001] The invention relates to a multi-dimensional distribution network risk assessment index system. Background technique [0002] Traditional distribution network risk assessment systems focus on the analysis of distribution network static security indicators, mainly focusing on the evaluation of single characteristics such as distribution network power supply reliability, security, power quality and construction scale. The content of these distribution network evaluation studies can improve the construction level of the distribution network from different aspects, but because it only evaluates from a single aspect of the distribution network, it cannot fully reflect the development level of the distribution network. Problems, the guiding significance for the development of distribution network is not strong. Simply assessing from the perspective of static security analysis, the established risk indicators are too academic and general, not specific enough...
