Embodiment Construction

[0048] Refer below figure 1 Describe in detail an embodiment of the method for constructing the power grid operation status index system provided by the present invention; figure 1 As shown, the construction process of implementing the primary power grid operation status indicator system in this embodiment mainly includes the following steps:

[0049] In the index model establishment step S1, according to the attributes of each power grid operation status index, a multi-layer index system model is established. The index system model includes a target layer with one index, at least first level content layer;

[0050] In the weight vector calculation step S2, a pairwise comparison based on the same layer is performed on all lower-level indicators belonging to the same upper-level indicator, and the weight vector of each lower-level indicator relative to its upper-level indicator is calculated;

[0051] In the indicator feature calculation step S3, the feature value of the indi...

Abstract

The invention provides a level analysis-based assessment method for grid operating condition indicators. The method comprises the following steps: establishing an indicator model: establishing an indicator system model of a multilayer structure according to attributes of all the grid operating condition indicators, wherein the indicator system model comprises a target layer with an indicator, and at least one level of content layer which subordinates to the target layer and has at least one indicator; calculating weight vectors: performing pairwise comparison based on the same layer on all lower layer indicators which subordinate to the same upper layer indicator, and calculating the weight vector of each lower layer indicator relative to the upper layer indicator; acquiring indicator characteristics: calculating a characteristic value of each indicator according to the weight vector. The invention also discloses a corresponding level analysis-based assessment system for the grid operating condition indicators. According to the level analysis-based assessment method and the level analysis-based assessment system for the grid operating condition indicators provided by the invention, the design and the establishment of a grid operating condition indicator system can be simplified, and accurate data are provided for the grid operating condition indicator system.

Description

technical field [0001] The invention relates to the field of electric power dispatching automation, in particular to a method and system for evaluating grid operation status indicators based on hierarchy analysis. Background technique [0002] In recent years, with the rapid development of economy and society, the scale of power grid has expanded rapidly. At the same time, various natural disasters and complex faults have brought great challenges to the safe and stable operation of power grids under extreme conditions. In this context, it is of great significance to study and establish a scientific and objective power grid operation status index system to promote the scientific development of the power grid and improve the management level of the power grid. [0003] The integrated grid operation smart system (Operation Smart System, OSS) and its power system operation cockpit module (Power system Operation Cockpit, POC) proposed by China Southern Power Grid is an important...
