Description

Technical Field

[0001] The present disclosure relates to the technical field of risk assessment of electric power communication systems, and in particular to a method and system for risk assessment of hidden dangers of electric power communication systems. Background Art

[0002] The statements in this section merely provide background art related to the present disclosure and do not necessarily constitute prior art.

[0003] The electric power communication network is another physical network of the power grid company in addition to the power grid. It is an operating platform that carries various types of electric power communication services, the basis for the safe and stable operation of the power grid primary system, and an important guarantee for the safe production of the power grid company. In particular, the basic transmission network of the electric power communication network is the foundation of the entire communication network. Although the transmission network has different protection methods at different levels, such as MSP protection at the optical path level, SNCP protection, 2M cut protection, AB port protection, etc. at the channel level, in the transmission network, when a node or two nodes are separated from the entire transmission network due to failure or maintenance, hidden risks will occur at the optical path level or the business channel level.

[0004] The inventors have found that the current common practice in the industry is to consult a large amount of complex information when designing or modifying transmission networks and business channels, and to analyze and compare to avoid potential risks and give reasonable creation or modification suggestions. Dispatchers must be very familiar with the entire transmission equipment network, optical cable network, business channels and other information, which greatly reduces the work efficiency of dispatchers and restricts dispatchers' maintenance work on transmission networks and business channels. Summary of the invention

[0005] In order to address the deficiencies in the prior art, the present disclosure provides a method and system for assessing hidden danger risks in an electric power communication system, which enables rapid characterization of hidden danger risk points in an electric power communication network and improves the accuracy of hidden danger level and risk level assessment of hidden danger points.

[0006] In order to achieve the above objectives, the present disclosure adopts the following technical solutions:

[0010] According to the acquired parameter data, hidden dangers are assessed, including at least four levels of hidden dangers:

[0011] When the protection and security control service channel is damaged, it is a level 4 hidden danger. When a channel under the protection and security control service is interrupted but the service is not interrupted, it is a level 3 hidden danger. When the protection and security control service is interrupted, it is a level 2 hidden danger. When all services under the protection group or primary line of the protection and security control service are interrupted, it is a level 1 hidden danger.

[0012] Furthermore, when a failure or maintenance occurs at a certain node, the fourth level hidden danger corresponds to the fourth level risk, the third level hidden danger corresponds to the third level risk, the second level hidden danger corresponds to the second level risk, and the first level hidden danger corresponds to the first level risk.

[0013] Furthermore, when a failure or maintenance occurs at two nodes, a level 4 hidden danger corresponds to a level 5 risk, a level 3 hidden danger corresponds to a level 4 risk, a level 2 hidden danger corresponds to a level 3 risk, and a level 1 hidden danger corresponds to a level 2 risk.

[0014] Further, the assessment of hidden dangers at all levels includes:

[0015] Get the primary line set RELAY_LINE_LIST where the business is located;

[0016] Get a line in RELAY_LINE_LIST, and get all the business sets associated with the line RELAY_LINE_RE_BUZ_LIST;

[0017] If all the services in the RELAY_LINE_RE_BUZ_LIST set are in the T_BUZ_LIST_BREAK set, the primary line in the RELAY_LINE_LIST set will be taken out of service and will be considered as a level 1 hidden danger;

[0018] If only one service is interrupted in RELAY_LINE_RE_BUZ_LIST, it is considered a level 2 risk;

[0019] If all services in RELAY_LINE_RE_BUZ_LIST are damaged, it is considered a level 3 risk;

[0020] If all services in RELAY_LINE_RE_BUZ_LIST are damaged, it is considered a level 4 hidden danger.

[0022] Get a line in the STEADY_LINE_LIST collection, and get all the business collections associated with the line, STEADY_LINE_RE_BUZ_LIST;

[0023] If all the services in the STEADY_LINE_RE_BUZ_LIST set are in the T_BUZ_LIST_BREAK set, the STEADY_LINE_LIST line will be out of service and will be considered a level 1 hidden danger.

[0024] If only one service is interrupted in STEADY_LINE_RE_BUZ_LIST, it is considered a level 2 risk;

[0025] If all services in STEADY_LINE_RE_BUZ_LIST are damaged, it is considered a level 3 risk;

[0026] If all services in STEADY_LINE_RE_BUZ_LIST are damaged, it is considered a level 4 risk.

[0027] Furthermore, the line port set T_PORT_LIST associated with the hidden danger risk point affecting the channel and the branch port set T_PORT_LIST_BRANCH associated with the device are obtained;

[0028] Get the channel set list T_CHANNEL_LIST_LINE_AFFECT associated with the line port set T_PORT_LIST;

[0029] Get the channel set list T_CHANNEL_LIST_BREAK associated with the branch port set T_PORT_LIST_BRANCH;

[0030] Channel list T_CHANNEL_LIST_ANALYSE =

[0031] T_CHANNEL_LIST_LINE_AFFECT-T_CHANNEL_LIST_BREAK.

[0032] Furthermore, the channel status in the channel list T_CHANNEL_LIST_BREAK is set to interrupt;

[0033] Determine the status of each channel in the T_CHANNEL_LIST_ANALYSE channel list:

[0034] Get a channel to be analyzed in the T_CHANNEL_LIST_ANALYSE list T_CHANNEL_ANALYSE;

[0035] Analyze T_CHANNEL_ANALYSE access routes T_CHANNEL_ROUTE_LIST;

[0036] If the number of routes in the T_CHANNEL_ROUTE_LIST set is zero, the T_CHANNEL_ANALYSE channel is added to the T_CHANNEL_LIST_BREAK set. If it is not zero, T_CHANNEL_ANALYSE is added to the T_CHANNEL_LIST_AFFECT list set, and the channel status in this set is impact;

[0037] Repeat the above steps to obtain the status of each channel in the T_CHANNEL_LIST_ANALYSE collection list.

[0038] Furthermore, according to the T_CHANNEL_LIST_BREAK set and the T_CHANNEL_LIST_AFFECT set, the service set T_BUZ_LIST associated with the channels in the two channel set lists is obtained;

[0039] Get a business to be analyzed T_BUZ_ANALYSE from the T_BUZ_LIST collection, and get the channel collection T_BUZ_RE_CHANNEL_LIST associated with T_BUZ_ANALYSE;

[0040] If the channel protection mode associated with the T_BUZ_ANALYSE service is emergency protection, and one of the channels is in T_CHANNEL_LIST_BREAK, the T_BUZ_ANALYSE service is added to the T_BUZ_LIST_BREAK set, and the service status in the set is interrupted;

[0041] If the channel protection mode associated with the T_BUZ_ANALYSE service is not emergency protection, and all channels in the T_BUZ_RE_CHANNEL_LIST set are in the T_BUZ_LIST_BREAK set, the T_BUZ_ANALYSE service is also added to the T_BUZ_LIST_BREAK set. In other cases, T_BUZ_ANALYSE is added to the T_BUZ_LIST_AFFECT set, and the service status in this set is defined as damaged.

[0063] like Figure 1 As shown, Embodiment 1 of the present disclosure provides a method for assessing hidden danger risks in a power communication system, including the following process:

[0064] S1: Establish hidden danger risk model

[0065] S1.1: Definition of hidden danger risk

[0066] Hidden danger point analysis refers to the impact on the network caused by problems in the analyzed network nodes. In order to prevent hidden dangers from happening, hidden dangers are checked. Risk refers to the probability of the hidden danger occurring. Because the number of hidden danger points selected is different, the probability of hidden dangers occurring is also different. Hidden danger points in the transmission network are defined by the degree of impact on the protection and security control services when one or two nodes (equipment or optical cables) in the network fail or are under maintenance. When the protection and security control service channel is damaged, it is defined as a fourth-level hidden danger. When a channel under the protection and security control service is interrupted, it is defined as a third-level hidden danger. When the protection and security control service is interrupted, it is defined as a second-level hidden danger. When all services under the protection group (or primary line) of the protection and security control service are interrupted, it is defined as a first-level hidden danger.

[0067] The existence of hidden danger points will inevitably bring certain risks. The risk level is defined according to the level of hidden danger points and the number of hidden danger points (probability of occurrence).

[0068] S1.1.1: The risk level of hidden dangers when a failure or maintenance occurs at a certain node (N-1) is defined as follows:

[0069] When the protection and security control business channel is damaged, it is defined as a level 4 risk. When a channel under the protection and security control business is interrupted but the business is not interrupted, it is defined as a level 3 risk. When the protection and security control business is interrupted, it is defined as a level 2 risk. When all businesses under the protection group of the protection and security control business are interrupted, it is defined as a level 1 risk.

[0070] S1.1.2: The risk level of hidden dangers when a failure or maintenance occurs at two nodes (N-2) is defined as follows:

[0071] When the protection and security control business channel is damaged, it is defined as a level 5 risk. When a channel under the protection and security control business is interrupted but the business is not interrupted, it is defined as a level 4 risk. When the protection and security control business is interrupted, it is defined as a level 3 risk. When all businesses under the protection group of the protection and security control business are interrupted, it is defined as a level 2 risk.

[0072] S1.2: Definition of protection business related models

[0073] Protection service refers to relay protection service, which is a very important service in the power communication network. The models related to this service include relay protection line model RELAY_LINE_MODEL, relay protection service model RELAY_BUZ_MODEL, channel model RELAY_BUZ_RE_CHANNEL_MODEL, model structure Figure 2 As shown, it can be seen that one relay protection line is associated with two relay protection services, and each relay protection service is associated with two primary and standby channels.

[0074] S1.3: Definition of models related to security services

[0075] The stability service is also a very important service in the power communication network. The models related to this service include the service protection group STEADY_GROUP_MODEL, the relay protection service model STEADY_BUZ_MODEL, the channel model STEADY_BUZ_RE_CHANNEL_MODEL, and the model structure Figure 3 shown.

[0076] S1.4: Device model definition

[0077] The device model is the basic model for potential risk point analysis and is also a type of potential risk point. Its related models include device T_NE, device frame T_NE_FRAME, device card T_NE_CARD, device port T_NE_PORT, device cross T_NE_CC, device topology T_TOPOLOGY, channel and time slot relationship T_NE_CC, model structure Figure 4 shown.

[0078] S1.5: Optical cable model definition

[0079] The optical cable model is the basic model for potential risk point analysis and is also a type of potential risk point. Its related models include optical cable T_OCABLE, optical cable segment T_OCABLE_SEG, optical cable core T_FIBER, wiring relationship T_BROAD_ROUTE_CONFIG, optical path T_BROAD, model structure Figure 5 shown.

[0080] S2: Definition of hidden danger risk analysis method

[0081] When investigating the potential risks of the transmission network in the power communication network, follow the following analysis process. The specific steps are as follows:

[0082] S2.1: Select possible hidden danger risk points and analyze the ports associated with the hidden danger risk points. Currently, the maximum number of hidden danger risk points that we can analyze simultaneously is 2, which means that at most two transmission devices, two optical cable segments, or one device plus one optical cable segment can be selected at the same time.

[0083] S2.1.1: Analysis of equipment hidden danger risk points affecting channel ports

[0084] Through the selected device, analyze all optical line port sets T_PORT_LIST_LINE_NE associated with the device, and all branch port sets T_PORT_LIST_BRANCH associated with the device

[0085] S2.1.2: Analysis of the risk points of optical cable hazards affecting channel ports

[0086] Analyze all ports associated with the device through the selected optical cable T_PORT_LIST_LINE_OCABLE

[0087] S2.1.3: Find the line port set associated with all the hidden danger risk points that affect the channel

[0088] T_PORT_LIST=T_PORT_LIST_LINE_NE∪T_PORT_LIST_LINE_OCABLE

[0089] S2.2: Analyze the list of channels affected by hidden danger risk points.

[0090] The cross information set is associated with the line port, and then the channel set list T_CHANNEL_LIST_LINE_AFFECT associated with the port set T_PORT_LIST is obtained through the cross information set.

[0091] Through the branch port set, obtain the channel set list T_CHANNEL_LIST_BREAK associated with the branch port set T_PORT_LIST_BRANCH.

[0092] T_CHANNEL_LIST_ANALYSE=T_CHANNEL_LIST_LINE_AFFECT-T_CHANNEL_LIST_BREAK;

[0093] S2.3: Analyze the channel status affected by hidden danger risk points

[0094] S2.3.1: Set the channel status in the T_CHANNEL_LIST_BREAK channel list to interrupt.

[0095] S2.3.2: Determine the status of each channel in the T_CHANNEL_LIST_ANALYSE channel list.

[0096] (1) Get a channel to be analyzed T_CHANNEL_ANALYSE in the T_CHANNEL_LIST_ANALYSE list.

[0097] (2) Analyze the routes T_CHANNEL_ANALYSE reaches T_CHANNEL_ROUTE_LIST (these routes do not pass through any port in the T_PORT_LIST set).

[0098] If the number of routes in the T_CHANNEL_ROUTE_LIST collection is 0, the T_CHANNEL_ANALYSE channel is added to the T_CHANNEL_LIST_BREAK collection. If it is not 0, T_CHANNEL_ANALYSE is added to the T_CHANNEL_LIST_AFFECT list collection, and the channel status in this collection is impact.

[0099] (3) Repeat steps (1) and (2) to analyze the status of each channel in the T_CHANNEL_LIST_ANALYSE collection list.

[0100] S2.4: Analyze the business status affected by hidden dangers and risk points

[0101] (1) According to the T_CHANNEL_LIST_BREAK set and the T_CHANNEL_LIST_AFFECT set, obtain the service set T_BUZ_LIST associated with the channels in the two channel set lists.

[0102] (2) Obtain a business to be analyzed T_BUZ_ANALYSE from the T_BUZ_LIST collection, and obtain the channel collection T_BUZ_RE_CHANNEL_LIST associated with T_BUZ_ANALYSE.

[0103] If the channel protection mode associated with the T_BUZ_ANALYSE service is emergency protection, and one of the channels is in T_CHANNEL_LIST_BREAK, the T_BUZ_ANALYSE service is added to the T_BUZ_LIST_BREAK set, and the service status in the set is interrupted.

[0104] If the channel protection mode associated with the T_BUZ_ANALYSE service is not emergency protection, and all channels in the T_BUZ_RE_CHANNEL_LIST set are in the T_BUZ_LIST_BREAK set, the T_BUZ_ANALYSE service is also added to the T_BUZ_LIST_BREAK set. In other cases, T_BUZ_ANALYSE is added to the T_BUZ_LIST_AFFECT set, and the service status in this set is defined as damaged.

[0105] S2.5: Analysis of service protection group (primary line status)

[0106] (1) According to the service list in S4, obtain the primary line RELAY_LINE_LIST where the service is located or the protection group STEADY_LINE_LIST of the stable service.

[0107] (2) Get a line in the RELAY_LINE_LIST primary line, and get the RELAY_LINE_RE_BUZ_LIST set of all services associated with the line. If all services in the RELAY_LINE_RE_BUZ_LIST set are in the T_BUZ_LIST_BREAK set, the RELAY_LINE_LIST primary line is decommissioned and marked as a level 1 hidden danger.

[0108] If there is only one service interruption in RELAY_LINE_RE_BUZ_LIST, it is defined as a level 2 hidden danger;

[0109] If all services in RELAY_LINE_RE_BUZ_LIST are damaged, it is defined as a level 3 hidden danger;

[0110] If all services in RELAY_LINE_RE_BUZ_LIST are damaged, it is defined as a level 4 hidden danger.

[0111] S2.6: Analysis of risk levels

[0112] If one hidden danger risk point is selected and N-1 analysis is performed, the risk level corresponding to the hidden danger in S5 is defined as follows:

[0113] Level 1 hidden danger corresponds to level 1 risk;

[0114] Level 2 hidden dangers correspond to level 2 risks;

[0115] Level 3 hidden dangers correspond to level 3 risks;

[0116] Level 4 hidden dangers correspond to level 4 risks.

[0117] If two hidden danger risk points are selected and N-2 analysis is performed, the risk level corresponding to the hidden danger in step 5) is defined as follows:

[0118] Level 1 hidden dangers correspond to level 2 risks;

[0119] Level 2 hidden dangers correspond to level 3 risks;

[0120] Level 3 hidden dangers correspond to level 4 risks;

[0121] Level 4 hidden dangers correspond to level 5 risks.

[0122] S3: Generate hidden danger risk point analysis report

[0123] According to the hidden danger risk analysis results, you can check whether there are hidden dangers when analyzing each node N-1 and N-2 in the network. If so, you can check the risk level of the hidden danger point, and further check the details of the relay protection line and status, safety and stability business group and status, business and business status, channel and channel status affected by the hidden danger point.

[0124] From a macro perspective, statistics are conducted based on the risk level of hidden dangers. Users can intuitively understand the number of hidden danger points at various levels in the existing transmission network, providing users with a highly available analysis solution for scientific planning, network transformation, business adjustment, and ensuring the robust operation of the network.
