[0016] Figure 1 A flow chart of a risk analysis method for a power communication network simulation platform proposed in the first embodiment of the present invention; Figure 2 This is a schematic diagram of the structure of the risk analysis system of the power communication network simulation platform proposed in the second embodiment of the present invention.

[0017] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] See also Figure 1 , which is a flow chart of a risk analysis method for a power communication network simulation platform in a first embodiment of the present invention, the method comprises steps S01 to S03, wherein: Step S01: obtaining a layout drawing of a power communication network, and constructing a simulation platform corresponding to the power communication network according to the layout drawing; It should be noted that in this embodiment, the constructed simulation platform supports fault simulation functions, including fault simulation generation, fault recovery, fault simulation result presentation, fault root cause analysis, and repeated fault simulation analysis. In addition, the simulation platform also supports historical fault playback function so that users can trace back at any time.

[0021] Specifically, regarding fault simulation generation, users are supported to manually set faults for resources. The simulation platform generates alarm information based on the faults, simulates the scenario of its propagation in the network, and then presents it on the interface. The simulation platform supports users to automatically generate faults by setting fault generation strategies after selecting a resource range, and simulates the scenario of its propagation in the network and presents it on the interface.

[0022] About fault recovery: Based on the fault simulation, users can perform fault recovery. They can choose to recover the fault on the topology map or in the fault information list.

[0023] Regarding the presentation of fault simulation results: it supports the establishment of a fault and alarm causal relationship library, performs data mining on historical faults to improve the rule library, and determines and analyzes the relevant root causes based on the alarm information collected in real time in the simulation network based on rule analysis, thereby realizing the diagnosis of faults in operation and maintenance.

[0024] Regarding repeated fault simulation analysis: The real platform provides comparison of two simulation results. For example, if the user selects the same historical fault simulation version for repeated simulation, where the simulation resources, services, topology and fault settings are the same, the system can compare whether the alarm information generated during the two simulations is the same.

[0025] Step S02: Perform NX risk analysis on the simulation platform in four dimensions, including designated faults for designated services, undesignated faults for designated services, designated faults for undesignated services, and undesignated faults for undesignated services; in this step, the simulation platform can also calculate the self-healing capability value of the power communication network according to the self-healing capability evaluation index system of the power communication network; in addition, based on the fault simulation, the simulation platform can simulate the protection switching process of the fault-related services. It mainly includes three aspects: self-healing capability evaluation, self-healing behavior simulation, and self-healing capability analysis.

[0026] The simulation platform can calculate the self-healing capability value of the power communication network based on the established self-healing evaluation indicators. The simulation platform divides the self-healing capability value into levels. When the score is at different levels, the system prompts the user to perform different protections. The score range of each level can be set by the user.

[0027] The simulation platform provides users with the ability to set the threshold of self-healing capability. When the self-healing capability is lower than the set threshold, a system alarm is generated. The objects of self-healing capability evaluation include: self-healing capability evaluation based on specified services, self-healing capability evaluation based on service types, and self-healing capability evaluation based on the entire network. At this time, users are required to set weights for each type of service.

[0028] In addition, the simulation platform can simulate the self-healing behavior of the network. The specific steps are as follows: Users set up one or more faults in the network; The simulation platform presents the corresponding fault resources and business resources affected by the fault on the topology interface; Users can select one or more services for self-healing simulation; The simulation platform performs self-healing simulation, switches services that meet the self-healing conditions to their protection paths, and visualizes the process on the interface; if the service does not meet the self-healing conditions, the simulation platform prompts the user that the service cannot self-heal.

[0029] The simulation platform can generate self-healing reports, including: faulty resources, affected services and their routing information, services that have successfully self-healed and their new routing information, and service information that has failed to self-heal.

[0030] In addition, the simulation platform also supports NX risk analysis of the business. That is, the user specifies X fault points, where the fault point is a device or a link. The simulation platform can perform NX analysis and generate a risk analysis report for the business from the following four dimensions. The specific process is as follows: First, all the business indicators involved are obtained, including three categories of line protection business, safety and stability business, dispatching automation business, dispatching telephone business, video conferencing business, administrative telephone business, and information business; For a specified business, specify a fault dimension: specify the business indicator to be analyzed; specify X fault points, and set the fault type of each fault point, where the fault type includes device type, link type, and mixed type; perform NX risk analysis.

[0031] For a specified business without specifying a fault dimension: specify the business indicator to be analyzed; specify X fault points and randomly match the fault type of each fault point; perform NX risk analysis.

[0032] For unspecified business-specified fault dimensions: randomly set the business indicators to be analyzed; select multiple devices to simulate faults; select multiple links to simulate faults; select the fault types for random simulated faults, including device and link fault types, and set the value of the number of fault points X when simulating faults, with the value of X ranging from 0 to 3; perform NX risk analysis.

[0033] For unspecified business and unspecified fault dimensions: randomly set the business indicators to be analyzed; select the fault type of the random simulated fault, and set the value of the number of fault points X when simulating the fault.

[0034] Step S03: Obtain risk analysis reports of the simulation platform in each dimension respectively.

[0035] It should be noted that the risk analysis report under each dimension includes: the number and list of services affected by each failure, the number and list of failed services, and the number and list of recoverable services.

[0036] After obtaining the risk analysis report, the recovery success rate of the services in each fault is calculated based on the number and list of failed services in each fault and the number and list of recoverable services in each fault. Finally, the average recovery success rate is calculated based on the recovery success rate of the services in each fault. The average recovery success rate reflects the survivability of the power communication network. If the average recovery success rate is high, it means that the survivability of the power communication network is strong. Otherwise, the power communication network needs to be optimized, as follows: Optimization includes defragmentation of network resources, routing optimization, load balancing, etc., so as to improve network structure and performance; Regarding resource fragmentation: The simulation platform can analyze the circuits with services in the time slot resources and the phenomenon of route disconnection, and clear them after the user confirms whether they are fragments.

[0037] Regarding route optimization: The simulation platform finds a better route and replaces the original route based on constraints such as the shortest route, latency, bandwidth, number of hops, equipment, and link life cycle quality.

[0038] About load balancing: The simulation platform can perform load balancing on the network so that resources in the network can be reasonably allocated and used.

[0039] In summary, according to the above-mentioned risk analysis method of the power communication network simulation platform, a simulation platform is pre-built for the power communication network to achieve a comprehensive risk assessment of the power communication network in multiple dimensions, and then accurately obtain the risk analysis data of the power communication network under different services and different fault conditions, so as to accurately simulate and evaluate the self-healing ability of the power communication network when a fault occurs, thereby evaluating the survivability of the power communication network, and providing a technical reference for the subsequent high-quality self-healing planning of the power communication network.
