Embodiment
[0126] Embodiment: adopt the method that proposes in the present invention to such as figure 2 The reliability of a single-service power communication network shown is analyzed. In the figure, there is business between node 1 and node 6, the main channel is 1‐2‐3‐4‐5‐8, the backup channel is 1‐6‐4‐7‐8, and the network and business are represented by a matrix:
[0127]
[0128] In the case of a single node failure, services will not be affected (except for the failure of the shared cross node 4). Here, the failure of node 3 is taken as an example for illustration. Then the new matrix is:
[0129]
[0130] Analyzing the above matrix, node 1 is connected to nodes 2 and 4, and the business prefers the main channel, but when the business passes through node 2, there are no other nodes connected to it, so this channel fails; the business can only be connected to node 4 through node 6, and then 1-6-4-7-8 is the backup channel, and 1-6-4-5-8 uses the backup channel 1-6- 4. T...

The invention provides an electric power communication network reliability analysis method. The electric power communication network reliability analysis method comprises steps that, a matrix method is utilized to describe the electric power communication network business topology; when the network business topology fails, a link failure matrix is generated; an influence scope of a failure link is analyzed through determining whether a business channel exists; crucial parts of a system are determined, a crucial part failure set is acquired; optimization for the crucial part failure set is carried out, and the smallest load business channel is acquired; a new thinking method is provided for electric power communication network reliability evaluation, the storage space of the network matrix is only represented in the process, problems of high complexity of the electric power communication network topology, large storage space and inconvenient calculation are simply and effectively solved.
Description
technical field [0001] The invention relates to an analysis method, in particular to an analysis method for the reliability of a power communication network. Background technique [0002] The power grid is designed to transmit the power resources produced by power generation enterprises to power consumption terminals through the transmission network, while the power communication network is the carrier of various information transmissions generated during the operation of the power grid system. It not only provides business channels for the connection of various protection equipment, It is also responsible for the communication between control centers, and between the control center and control equipment, the transmission and sharing of various information, the realization of signal communication between protection equipment, and the timely and accurate arrival of scheduling information. [0003] The main business of the power communication network includes power production ...
