Embodiment 1

[0050] This embodiment provides a power grid reliability analysis method, which is suitable for analyzing the reliability of the power grid system, such as figure 1 As shown, the method includes the following steps:

[0051] S11: Extract the characteristic parameters and the number of characteristic parameters corresponding to each analysis object in the power grid system. Here, the analysis objects can be various attributes of components in the power grid system, and the characteristic parameters can be parameters that characterize various attributes. For example, in In the power optical cable network, since the power optical cable network is a collection of nodes and links, the analysis object can be obtained by collecting and arranging the operation analysis data of the power optical cable network of the power supply enterprise. The analysis object can be mechanical strength, equipment environment, engineering quality, fiber aging , where the characteristic parameters of me...

Abstract

The invention provides a power network reliability analysis method and apparatus. The method comprises the steps of extracting a characteristic parameter corresponding to each analysis object and a quantity of characteristic parameters in a power network system; obtaining a comparative sequence and a reference sequence of the characteristic parameters; performing calculation according to the quantity of the characteristic parameters, the comparative sequence and the reference sequence to obtain a correlation coefficient of the comparative sequence and the reference sequence; and determining values of influence degrees of the characteristic parameters on power network reliability according to the quantity of the characteristic parameters and the correlation coefficient. According to the scheme, the relationships between the characteristic parameters and the analysis objects are fully considered, the analytic calculation process is simplified, and the dependency on subjective experience is reduced, so that the subjectivity, accuracy and comprehensiveness of power network reliability analysis are improved.

Description

technical field [0001] The invention relates to the field of grid security, in particular to a grid reliability analysis method and device. Background technique [0002] Since the mid-1990s, regional power grids connected to provinces have been gradually developed, and cross-regional ultra-high voltage power grids have also been initially constructed. This puts forward higher requirements for long-distance communication. Therefore, optical fiber communication technology has emerged and matured day by day. Due to its high bandwidth, low attenuation, long distance, anti-interference, low cost and other characteristics, optical fiber communication has brought an unprecedented revolution to the power communication system. [0003] At present, my country has built a "three vertical and four horizontal" power optical cable backbone network, forming a communication network pattern in which optical fiber communication is the mainstay, and multiple communication methods such as power...
