Example Embodiment

[0054] The technical solution provided by the present invention will be further described in detail below in conjunction with the description of the drawings and specific embodiments.

[0055] The present invention proposes a method for analyzing the factors affecting the reliability of distribution networks based on conceptual clustering, taking 10kV lines as the analysis object, and extracting line reliability feature sets related to reliability from the aspects of topology, equipment attributes, operation indicators, etc. , Use conceptual clustering method to classify route samples based on the set of reliability features, and generate a multi-level classification pattern tree. Each level represents a way to classify all route samples. Each type of route has a set of several The feature-value pairs (called the salient feature vector) that meet the classification constraints.

[0056] On the other hand, considering various natural, social and human factors that may affect the rel...

Abstract

The invention provides a power distribution network reliability influence factor analysis method based on cluster analysis. The power distribution network reliability influence factor analysis methodcomprises steps of establishing a line reliability characteristic cluster, calculating an original characteristic vector and a clustering analysis element set and determining an optimal area-line pair. The power distribution network reliability influence factor analysis method based on cluster analysis considers an integrated impact caused by multiple factors while performing power distribution network reliability and helps power grid planning staff to make more effective planning technology principle.

Description

Technical field [0001] The invention relates to the field of power system big data analysis methods, and in particular to an analysis method of factors influencing the reliability of distribution networks based on cluster analysis. Background technique [0002] Power supply reliability evaluates the continuous power supply capability of the power supply system by comprehensively measuring the statistical indicators that reflect the user's power outage in the power supply system. In recent years, the reliability of the distribution network has gradually become the focus of attention of power grid companies, especially for the management and application of reliability indicators in the distribution planning business. [0003] At present, reliability-based distribution network planning methods are widely adopted in the world, combined with the development status and future trends of regional distribution networks, from the four aspects of grid architecture, equipment, technology, and ...
