本申请要求于2021年11月26日提交中国专利局、申请号为202111425790.4、发明名称为“基于模块化配置的配电终端及其拓扑模型验证方法和装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application submitted to the China Patent Office on November 26, 2021, with the application number 202111425790.4, and the title of the invention is "Power distribution terminal based on modular configuration and its topology model verification method and device". The entire contents are incorporated by reference in this application.
技术领域technical field
本发明涉及配电网技术领域，尤其涉及基于模块化配置的配电终端及其拓扑模型验证方法和装置。The invention relates to the technical field of power distribution network, in particular to a power distribution terminal based on modular configuration and a topology model verification method and device thereof.
背景技术Background technique
传统箱式结构的配电终端有统一的外箱，其中通过插槽设置固定数量的电源板、中央处理器板和模拟采集板。插槽的位置相对固定，插槽数量有限，在一定程度上限制了配电终端的可扩展性和灵活性，不能满足工程现场的实际情况。配电终端设升级意味着设备需要整体更换，改造维护成本较大。The power distribution terminal of the traditional box structure has a unified outer box, in which a fixed number of power supply boards, central processing boards and analog acquisition boards are arranged through slots. The position of the slot is relatively fixed, and the number of slots is limited, which limits the scalability and flexibility of the power distribution terminal to a certain extent, and cannot meet the actual situation of the engineering site. The upgrade of the power distribution terminal means that the equipment needs to be replaced as a whole, and the cost of transformation and maintenance is relatively high.
为提高配电网可靠性，需要在配电终端中使用分布式FA(馈线自动化)。分布式FA可以通过配电终端的协调和协作来完成故障定位、隔离和恢复。它依赖于存储在配电终端本身的拓扑信息，不需要与主站通信。可见，分布式解决方案的有效性与存储在每个配电终端的拓扑模型的准确性密切相关。因此，为提高分布式FA的可靠性，有必要对配电终端的拓扑模型进行验证。In order to improve the reliability of the distribution network, it is necessary to use distributed FA (feeder automation) in the distribution terminal. Distributed FA can complete fault location, isolation and recovery through the coordination and cooperation of power distribution terminals. It relies on topology information stored in the distribution terminal itself and does not need to communicate with the master station. It can be seen that the effectiveness of the distributed solution is closely related to the accuracy of the topology model stored at each distribution terminal. Therefore, in order to improve the reliability of distributed FA, it is necessary to verify the topology model of power distribution terminals.
然而，大部分的研究都集中在主站的拓扑模型上，目前还没有有效的验证方法用于对配电终端的拓扑模型进行验证。However, most of the research focuses on the topology model of the main station, and there is no effective verification method for verifying the topology model of the distribution terminal.

Obviously, the following The described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
请参阅图1，图1示出了本发明实施例提供的一种基于模块化配置的配电终端的结构示意图。Please refer to FIG. 1 . FIG. 1 shows a schematic structural diagram of a power distribution terminal based on a modular configuration provided by an embodiment of the present invention.
本发明的一种基于模块化配置的配电终端，包括电源模块1、核心控制模块2和多个子功能模块3；A power distribution terminal based on modular configuration of the present invention includes a power supply module 1, a core control module 2 and a plurality of sub-function modules 3;
所述电源模块1通过电源总线连接所述核心控制模块2及各所述子功能模块3，以用于提供电源；The power supply module 1 is connected to the core control module 2 and each of the sub-function modules 3 through a power bus to provide power;
各所述子功能模块3及核心控制模块2之间采用基于抢占机制的全双工高速数据总线进行通信；A full-duplex high-speed data bus based on a preemption mechanism is used for communication between each of the sub-function modules 3 and the core control module 2;
所述核心控制模块2用于对各所述子功能模块3进行协调和控制，并用于对扩展的子功能模块3进行自动识别和注册。The core control module 2 is used for coordinating and controlling each of the sub-function modules 3 , and for automatically identifying and registering the extended sub-function modules 3 .
本发明实施例中，根据不同的功能需求将配电终端的各硬件设计为独立的硬件模块，各模块可以任意组合安装。In the embodiment of the present invention, each hardware of the power distribution terminal is designed as an independent hardware module according to different functional requirements, and each module can be installed in any combination.
进行结构的具体设计时，子功能模块3作为核心控制模块2的连接模块，可以安装在导轨地板上，而核心控制模块2可独立安装在连接地板上，从而可以在不拆除底部接线的情况下拔出核心控制模块2，以实现核心控 制模块2的更换。When carrying out the specific design of the structure, the sub-function module 3, as the connection module of the core control module 2, can be installed on the rail floor, and the core control module 2 can be independently installed on the connection floor, so that it can be connected without removing the bottom wiring. Pull out the core control module 2 to realize the replacement of the core control module 2.
子功能模块3的类型和数量，可以根据项目需求而定。现场配置时，由于不再使用机箱插件结构设计，项目现场可以根据需要任意展开和组装子功能模块3。按照模块类型进行分类，所述多个子功能模块3可以包括模拟采集模块31、数字量采集模块32、数字量输出模块33、GPRS无线公共网络通信模块34及广播和航空通讯模块35，各子功能模块3在核心控制模块2的统一协调和调度下提供相应的服务。各子功能模块3与核心控制模块2、电源模块1的连接关系如图2所示。The type and quantity of sub-function modules 3 can be determined according to project requirements. During on-site configuration, since the chassis plug-in structure design is no longer used, the sub-function modules 3 can be deployed and assembled arbitrarily at the project site according to needs. Classify according to module type, described multiple sub-function modules 3 can comprise analog acquisition module 31, digital quantity acquisition module 32, digital quantity output module 33, GPRS wireless public network communication module 34 and broadcast and aviation communication module 35, each subfunction Module 3 provides corresponding services under the unified coordination and scheduling of core control module 2. The connection relationship between each sub-function module 3 and the core control module 2 and the power module 1 is shown in FIG. 2 .
基于模块化配置的配电终端，在电源模块1的辅助下，通过核心控制模块2协调和控制整个设备的运行。各子功能模块3独立完成各自的数据采集和系统运行监控功能，并将采集和监控的数据实时上报给所述核心控制模块2。核心控制模块2对数据进行存储和计算，并上传至主站。同时，各子功能模块3接收并执行核心控制模块2发出的参数设置和控制指令。The power distribution terminal based on the modular configuration, with the assistance of the power module 1, coordinates and controls the operation of the entire device through the core control module 2. Each sub-function module 3 independently completes its own data collection and system operation monitoring functions, and reports the collected and monitored data to the core control module 2 in real time. The core control module 2 stores and calculates the data, and uploads it to the master station. At the same time, each sub-function module 3 receives and executes the parameter setting and control instructions issued by the core control module 2 .
模块间的通信接口采用高速全双工数据总线设计。最高通信速率可达10Mbps以上。为了保证通信的可靠性，采用差分信号来发送信号。在数据传输过程中，核心控制模块2是通信的主要模块。在硬件上，通信接口包括两组差分信号和一组状态信号，这两组差分信号分别是下行数据传输信号和上行数据传输信号。状态信号用于检测总线状态，并在模块传输数据时抢占上游数据总线的使用权。The communication interface between the modules adopts a high-speed full-duplex data bus design. The highest communication rate can reach more than 10Mbps. In order to ensure the reliability of communication, differential signals are used to send signals. In the process of data transmission, the core control module 2 is the main module of communication. In terms of hardware, the communication interface includes two sets of differential signals and a set of status signals, and the two sets of differential signals are downlink data transmission signals and uplink data transmission signals respectively. The status signal is used to detect the bus status and preempt the right to use the upstream data bus when the module transmits data.
在一种能够实现的方式中，所述全双工高速数据总线包括两组差分数据总线和一组差分控制总线，所述差分数据总线用于数据传输，所述差分控制总线用于在数据传输时进行信道状态检测及信道资源抢占。In an implementable manner, the full-duplex high-speed data bus includes two sets of differential data buses and a set of differential control buses, the differential data buses are used for data transmission, and the differential control buses are used for data transmission The channel state detection and channel resource preemption are carried out in real time.
在数据传输的过程中，所述差分控制总线首先检测信道状态。如果信道空闲，则快速获得使用该信道的权限以进行数据传输。数据传输完成后，该信道的使用权限将被释放。为了保证模块之间数据传输的效率，每个模块必须对传输的数据量进行一次限制，以确保所有的数据传输都在权限使用的时限内完成。一旦拥有时间超过限制，信道使用权将被强制释放。During data transmission, the differential control bus first detects channel status. If the channel is free, quickly obtain permission to use the channel for data transfer. After the data transmission is completed, the permission to use the channel will be released. In order to ensure the efficiency of data transmission between modules, each module must limit the amount of transmitted data once to ensure that all data transmissions are completed within the time limit of the authority. Once the ownership time exceeds the limit, the channel usage right will be forcibly released.
为了降低配电终端的设备安装、调试和运行维护成本，配电终端的各个模块之间必须实现基于自动注册/发现/退出机制的即插即用功能。当需要 扩展模块时，只需将扩展的子功能模块3安装在导轨上，并完成外部布线，无需承担任何责任。每个子功能模块3上电后，应先注册到核心控制模块2。注册成功后，核心控制模块2对其进行协调和控制。当有需要更换的模块时，只需要更换对应模块的硬件，上电后，新模块也会被更换。当某个模块需要退出系统时，需要将该模块的硬件从导轨中取出。In order to reduce the equipment installation, commissioning, operation and maintenance costs of the power distribution terminal, the plug-and-play function based on the automatic registration/discovery/exit mechanism must be realized between the various modules of the power distribution terminal. When an expansion module is needed, only the expanded sub-function module 3 needs to be installed on the guide rail, and the external wiring needs to be completed without any responsibility. After each sub-function module 3 is powered on, it should be registered with the core control module 2 first. After the registration is successful, the core control module 2 coordinates and controls it. When there is a module that needs to be replaced, only the hardware of the corresponding module needs to be replaced, and the new module will also be replaced after power-on. When a module needs to exit the system, the hardware of the module needs to be taken out from the guide rail.
为实现模块的即插即用功能，在一种能够实现的方式中，所述核心控制模块2包括用于对扩展的子功能模块3进行识别和注册的更新检测单元；In order to realize the plug-and-play function of the module, in an achievable manner, the core control module 2 includes an update detection unit for identifying and registering the extended sub-function module 3;
所述更新检测单元包括：The update detection unit includes:
接收子单元，用于接收扩展的子功能模块3发送的注册请求，所述注册请求包括设备标识符；The receiving subunit is configured to receive a registration request sent by the extended sub-function module 3, where the registration request includes a device identifier;
识别子单元，用于根据所述设备标识符识别扩展的子功能模块3的设备类型和物理地址；An identifying subunit, configured to identify the device type and physical address of the extended sub-function module 3 according to the device identifier;
注册子单元，用于根据所述设备类型和物理地址更新对应的设备配置信息。The registration subunit is configured to update corresponding device configuration information according to the device type and physical address.
其中，设备标识符为用32位整数表示的标识，其中，0-23位用于标识物理地址，24-31位用于表示设备类型。每个子功能模块3都有唯一的模块类型标识。物理地址识别是通过拨号产生的，当有多个相同模块时，根据需要调整拨号代码，以获得不同的物理地址。Wherein, the device identifier is an identifier represented by a 32-bit integer, wherein 0-23 bits are used to identify a physical address, and 24-31 bits are used to indicate a device type. Each sub-function module 3 has a unique module type identification. Physical address identification is generated by dialing. When there are multiple identical modules, adjust the dialing code as needed to obtain different physical addresses.
本发明还提供一种配电终端的拓扑模型验证方法，所述配电终端为如上任意一项能够实现的方式所述的基于模块化配置的配电终端。The present invention also provides a method for verifying a topology model of a power distribution terminal. The power distribution terminal is a power distribution terminal based on modular configuration described in any one of the above methods that can be realized.
请参阅图3，图3示出了本发明实施例提供的一种配电终端的拓扑模型验证方法的流程图。Please refer to FIG. 3 . FIG. 3 shows a flowchart of a method for verifying a topology model of a power distribution terminal provided by an embodiment of the present invention.
所述方法包括：The methods include:
步骤S1，基于与邻居配电终端的点对点通信，收集所属区域的本地拓扑模型信息；Step S1, based on point-to-point communication with neighboring power distribution terminals, collecting local topology model information of the area to which it belongs;
步骤S2，根据所述本地拓扑模型信息生成对应的SCL文件；Step S2, generating a corresponding SCL file according to the local topology model information;
步骤S3，通过消息摘要算法对所述对应的SCL文件进行计算，得到对应的指纹信息；Step S3, calculating the corresponding SCL file through a message digest algorithm to obtain corresponding fingerprint information;
步骤S4，基于与邻居配电终端的点对点通信，利用共识算法生成对应 所有SCL文件的指纹平均值信息；Step S4, based on point-to-point communication with neighbor power distribution terminals, using consensus algorithm to generate fingerprint average information corresponding to all SCL files;
步骤S5，根据主站的第一验证请求向所述主站发送所述指纹平均值信息，以由所述主站根据所述指纹平均值信息与所述标准指纹信息的比较结果来验证拓扑模型的正确性。Step S5, sending the average fingerprint information to the master station according to the first verification request from the master station, so that the master station can verify the topology model according to the comparison result between the average fingerprint information and the standard fingerprint information correctness.
作为优选，该消息摘要算法为MD5摘要算法(消息摘要算法第五版)。其是一种被广泛使用的密码散列函数，可以产生出一个128位(16字节)的散列值，用于确保信息传输完整一致。Preferably, the message digest algorithm is an MD5 digest algorithm (the fifth edition of the message digest algorithm). It is a widely used cryptographic hash function that can generate a 128-bit (16-byte) hash value to ensure the integrity and consistency of information transmission.
传统的验证方法要求每个配电终端通过IEC60870-5-104等协议与主站进行通信。因此，传统的验证方法使得主站通信负担沉重，不适用于主站通信能力有限的配电网。本实施例利用对等通信链路跟随一个一致变量来表示全局信息。在比较过程中，由消息摘要算法生成SCL文件的指纹信息，这将大大减少通信时间。此外，主站与任意配电终端通信，以比较由自己的模型产生的一致变量。如果两个变量相同，则意味着两种模型相同；如果两个变量不同，则利用修正过程更新模型。这意味着在验证过程中只需要一次通信，大大降低了主站的通信负担。Traditional verification methods require each power distribution terminal to communicate with the master station through protocols such as IEC60870-5-104. Therefore, the traditional verification method makes the communication burden of the master station heavy, and is not suitable for the distribution network with limited communication ability of the master station. This embodiment utilizes a peer-to-peer communication link followed by a consistent variable to represent global information. During the comparison process, the fingerprint information of the SCL file is generated by the message digest algorithm, which will greatly reduce the communication time. In addition, the master station communicates with any distribution terminal to compare the consistent variables produced by its own model. If the two variables are the same, it means that the two models are the same; if the two variables are different, the model is updated using the correction procedure. This means that only one communication is required during the verification process, greatly reducing the communication burden on the master station.
本实施例利用共识算法生成对应所有SCL文件的指纹平均值信息。共识问题起源于计算机科学，它用于促进大量分布式终端之间的协作。共识算法的一般目的是通过点对点通信强制一组终端就几个数量达成协议。考虑到数字通信的离散性，一致变量应写成离散形式：In this embodiment, a consensus algorithm is used to generate average fingerprint information corresponding to all SCL files. The consensus problem originated in computer science, where it is used to facilitate collaboration among a large number of distributed terminals. The general purpose of a consensus algorithm is to force a group of terminals to reach an agreement on a few quantities through peer-to-peer communication. Considering the discrete nature of digital communication, the consistent variable should be written in discrete form:

Figure PCTCN2022126938-appb-000001
式中，N i表示相邻配电终端的集合，其中配电终端i的相邻配电终端为与该配电终端i存在通信链路的其他配电终端。

is the consistent variable at the k+1th iteration, and ε is the edge weight used to adjust the dynamics of the consistent algorithm.
整个系统的紧致形式可以写成：The compact form of the whole system can be written as:

式中，c k＝(c k1，c k2，...，c kn)，其表示整个系统的一致性变量向量， L为拉普拉斯矩阵，其定义了一致性算法的动态。 In the formula, c k =(c k 1, c k 2,..., c k n), which represents the consistency variable vector of the whole system, L is the Laplacian matrix, which defines the dynamics of the consensus algorithm .
在一种能够实现的方式中，所述方法还包括：In an achievable manner, the method also includes:
接收所述主站发送的修正指令，所述修正指令由所述主站在所述指纹平均值信息与所述标准指纹信息不一致时发送；receiving a correction instruction sent by the master station, where the correction instruction is sent by the master station when the fingerprint average information is inconsistent with the standard fingerprint information;

若所述指纹平均值信息与所述标准指纹信息不一致，对所存储拓扑模型进行修正。If the fingerprint average information is inconsistent with the standard fingerprint information, the stored topology model is corrected.
本发明实施例中，该方法利用消息摘要算法和共识算法生成模型的指纹信息，并通过指纹信息比较。这样，主站只需与一个配电终端进行通信就可以实现比较，大大简化了拓扑模型的验证过程，提高了验证速度。In the embodiment of the present invention, the method uses the message digest algorithm and the consensus algorithm to generate the fingerprint information of the model, and compares the fingerprint information. In this way, the master station only needs to communicate with one power distribution terminal to realize the comparison, which greatly simplifies the verification process of the topology model and improves the verification speed.
