Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a self-healing method for a power distribution network feeder communication node according to an embodiment of the present invention, where the present embodiment is applicable to any power distribution network feeder communication scenario, and the method may be executed by a self-healing apparatus for a power distribution network feeder communication node according to an embodiment of the present invention, where the apparatus may be implemented by software and/or hardware, and may be integrated in an electronic device.
As shown in fig. 1, the self-healing method of the feeder communication node of the power distribution network includes:
and S110, if the static routing faults of the communication nodes and the directly connected transformer substations exist in the lower-connection power distribution network line, constructing a dynamic routing of a power distribution network loop between the two transformer substations.
The distribution data network is an infrastructure for realizing real-time production data transmission and exchange between regional dispatching and transformer substations. The distribution data network needs to have the characteristics of strong real-time performance and high reliability, and the safety of the distribution data network is directly related to the safe and stable operation of the power grid. The power distribution data network can be divided into a core layer, a convergence layer and an access layer 3 according to the structure. The core layer may be used to implement data transmission between backbone networks. The access stratum may be a directly connection-oriented or access-oriented part of the network. The convergence layer can be used as a medium between the access layer and the core layer, and convergence is performed before the access layer accesses the core layer, so that the load of core layer equipment is reduced.
According to the scheme, the self-healing device of the feeder line communication node of the power distribution network can be configured in the convergence layer and the access layer device, the self-healing device can detect whether a static routing fault exists between the communication node in the lower-connection power distribution network line and the convergence layer device of the direct-connection transformer substation or not when the self-healing device executes the scheme. The lower-connection distribution network line can be an access layer line of convergence layer equipment which is totally converged to the transformer substation, and can also be a line on one side of the load of the transformer substation in the distribution network. One or more communication nodes may be present in the downlink distribution network, which may be active electronic devices connected to the network. The directly connected substation may be a substation that loads communication nodes, and for the communication nodes, the directly connected substation may be preset according to a distance. The communication node is arranged in a lower-connection distribution network line of at least two substations, wherein a distribution network loop is formed between the at least two substations. It should be noted that, for the communication node, at least one of the at least two substations is a direct-connected substation. Static routes can be configured between the communication nodes and the directly connected substations. The routing entries of the static route may be manually configured, rather than dynamically determined. The network adopting the static routing has high security and saves communication resources.
When the self-healing device detects that a static routing fault of a communication node and a directly connected substation exists in a lower power distribution network line, it is indicated that communication between the communication node and convergence layer equipment of the directly connected substation may be faulty, for example, communication is interrupted. At the moment, the self-healing device can construct a dynamic route of a power distribution network loop between the convergence devices of the two substations. The two substations can comprise the directly-connected substation and a substation connected with the currently-directly-connected substation, and one or more substations connected with the currently-directly-connected substation can be provided. It should be noted that, when there are a plurality of substations connected to the current directly-connected substation, the self-healing device may select a suitable substation according to a preset distribution network loop construction principle. According to the power distribution network loop building principle, a nearby substation can be selected according to the transmission distance, and a substation with a rapid convergence layer device of the transmission rate can also be selected according to the transmission rate. The dynamic routing may be pre-configured to the convergence layer devices and the communication nodes of all the substations, or may be automatically configured to the convergence layer devices and the communication nodes of the corresponding substations after being triggered by a static routing fault. The dynamic routing can automatically build its own routing table according to the specific routing information exchanged between the routers, and can automatically adjust in time according to the changes of links and communication nodes. When communication nodes or links between communication nodes in the network fail or other available routes exist, the dynamic route can automatically select the best available route and continue to forward the message.
And S120, based on the dynamic routing, performing network communication with the fault communication node through a target substation except the direct-connected substation of the fault communication node, so as to perform self-healing of the feeder line communication node of the power distribution network.
According to the configured dynamic route, the failed communication node can perform network communication with convergence layer equipment of a target substation except the directly-connected substation, and further data transmission is achieved. Data information on the feeder line communication node of the power distribution network cannot be lost, and can be continuously transmitted through convergence layer equipment of a target transformer substation, so that real-time acquisition of power dispatching data can be realized.
In this embodiment, optionally, before detecting that a static routing fault of a communication node and a directly connected substation exists in a downstream distribution network line, the method further includes:
establishing a virtual routing redundancy protocol in a power distribution network loop formed between the at least two substations; the virtual route redundancy protocol is used for defining a basic route as a static route and a backup route as a dynamic route.
Before detecting the static routing fault, the self-healing device can also establish a virtual routing redundancy protocol in a power distribution network loop formed between convergence layer devices of at least two substations. The virtual route redundancy protocol is a route fault tolerance protocol, which can also be called a backup route protocol. The virtual route redundancy protocol may be used to define the base route as a static route and the backup route as a dynamic route.
According to the scheme, a virtual route redundancy protocol is established in a power distribution network loop, a basic route is defined as a static route, and a backup route is defined as a dynamic route. According to the scheme, the self-healing of the feeder line communication node of the power distribution network can be realized through dynamic routing after the static routing fault is detected, the stable operation of the feeder line automatic service of the power distribution network is guaranteed, and the communication reliability is improved.
In this scheme, optionally, each of the at least two substations is provided with a substation convergence layer device, and a power distribution network loop formed between the at least two substations is formed through an access layer static route configured on the substation convergence layer device.
According to the scheme, the transformer substation convergence layer equipment is arranged at each transformer substation, and the access layer static routing configured on the transformer substation convergence layer equipment can reduce the load of the core layer equipment, so that the reliability of communication is ensured, and the data transmission rate is improved.
In a possible embodiment, optionally, the method further includes:
setting a network quality detection mechanism in a power distribution network loop formed between the at least two substations; and determining whether a static routing fault exists in a communication node in a downlink power distribution network line according to a detection result of the network quality detection mechanism.
In this embodiment, the self-healing device may further set a network quality detection mechanism in the power distribution network loop, so as to determine whether a static routing fault exists in the communication node in the downlink power distribution network line. The network quality detection mechanism can be a real-time network performance detection and analysis technology, and can analyze and count information such as network jitter, packet loss rate, network delay and the like, monitor the service quality of the network in real time, and simultaneously can quickly locate a fault point. And determining whether a static routing fault exists in a communication node in the downlink power distribution network line according to one or more detection results of the network quality detection mechanism. For example, whether a static routing fault exists in a communication node in a downlink power distribution network can be determined according to whether the network packet loss rate is 100% in a preset time.
Through setting up network quality detection mechanism, whether communication node has static route trouble in the distribution network line of lower antithetical couplet not only can be judged to the self-healing device, can also evaluate other performances of communication node in the distribution network line. According to the scheme, the network quality detection mechanism can be utilized to realize rapid and accurate static routing fault detection, the stability of the operation of the power distribution data network is guaranteed, and communication faults are eliminated in time.
In a preferred embodiment, optionally, the constructing a dynamic route of a distribution network loop between two substations includes:
and based on the virtual routing redundancy protocol, after determining that the static routing of the distribution network loop formed between the at least two substations is invalid, controlling the dynamic routing to take effect so as to construct the dynamic routing of the distribution network loop between the at least two substations.
On the basis of the scheme, based on the virtual routing redundancy protocol, after the self-healing device determines the effectiveness of the static routing of the power distribution network loop, the dynamic routing can be controlled to take effect immediately according to the defined backup routing, and then the dynamic routing of the power distribution network loop is constructed.
The scheme utilizes the virtual route redundancy protocol to control the dynamic route to take effect immediately after the static route is effective. The scheme can fully utilize the advantages of static routing and dynamic routing, and give consideration to the stability and flexibility of the power distribution data network, thereby ensuring the efficient operation of the power distribution data network.

(1) a virtual route redundancy protocol is established between the two substations;
(2) configuring a communication node static route of an access layer on convergence layer equipment of two transformer substations;
(3) a network quality detection mechanism is configured and linked with a static route so as to judge whether the convergence layer equipment of the two substations can normally communicate with the communication node of the access layer;
(4) establishing a dynamic routing protocol, such as an IGP (Interior Gateway protocol), between two substations, introducing a static routing of a communication node, and replacing the static routing by the dynamic routing when the static routing fails due to a fault, thereby realizing routing conversion;
(5) and realizing routing summary on the convergence layer equipment of the transformer substation through policy control, so that the core layer routing table is not influenced by the sharp increase of routing entries.

The scheme can ensure the stable operation of feeder automation services of the power distribution network, improve the communication reliability and save communication resources.
