相关技术中,网络设备(例如5G通信网络设备)由于其使用高频段进行通信的特性,受电磁环境的影响较小。但是网络设备中通常有大量电子元器件组成,且大量使用微电子技术来实现通信功能,这就导致网络设备对于强电磁环境的干扰具有很高的敏感性,当网络设备在强电磁环境下工作时,网络设备能将会受到影响,甚至网络设备的安全性也无法保证。In related technologies, network equipment (such as 5G communication network equipment) is less affected by the electromagnetic environment due to its characteristic of using high frequency bands for communication. However, network equipment usually consists of a large number of electronic components, and a large amount of microelectronics technology is used to implement communication functions. This causes network equipment to be highly sensitive to interference from strong electromagnetic environments. When network equipment works in a strong electromagnetic environment, At this time, the performance of network equipment will be affected, and even the security of network equipment cannot be guaranteed.

当网络设备安装在变电站内时,由于变电站的高压系统中的大量设备都有很大的电流,使得变电站的高压系统形成一个强大的干扰源,在变电站正常运行或者故障时都会产生各种稳态或暂态干扰,例如,对某个大电流设备进行开关操作时,将会引起暂态干扰。此外,当变电站设备发生短路故障时,变电站设备会使得附近的电磁场和工频电位的升高,这样同样会对网络设备的正常工作造成很大干扰。When network equipment is installed in a substation, since a large number of devices in the high-voltage system of the substation have large currents, the high-voltage system of the substation forms a powerful source of interference, which will produce various steady states during normal operation or failure of the substation. Or transient interference, for example, when switching a high-current device, transient interference will be caused. In addition, when a short-circuit fault occurs in the substation equipment, the substation equipment will increase the nearby electromagnetic field and power frequency potential, which will also cause great interference to the normal operation of the network equipment.

当前设计的网络设备的电磁兼容性标准通常不能很好的适用于变电站的复杂电磁环境,因此,当网络设备设置在变电站时,可能会受到变电站的高压系统的电磁干扰,这样会严重影响网络设备的安全运行,甚至出现网络设备的损坏,进而导致通信系统无法安全可靠的运行。因此,如何在变电站这样复杂的电磁环境中对网络设备的安全性进行评估成为亟待解决的技术问题。The electromagnetic compatibility standards of currently designed network equipment are usually not well suited to the complex electromagnetic environment of substations. Therefore, when network equipment is installed in a substation, it may be subject to electromagnetic interference from the high-voltage system of the substation, which will seriously affect the network equipment. The safe operation of the network equipment may even be damaged, resulting in the inability of the communication system to operate safely and reliably. Therefore, how to evaluate the security of network equipment in a complex electromagnetic environment such as a substation has become an urgent technical problem to be solved.

Among them, the specification parameter information of the network equipment includes: the manufacturer information, size, antenna height, antenna downtilt angle, antenna type, etc. of the network equipment. According to the installation location information of the network equipment, the relative location information of the network equipment in the substation equipment is determined.

When the power frequency magnetic field strength at the relative installation position is less than or equal to the power frequency magnetic field strength safety threshold of the network equipment, it is evaluated that the power frequency magnetic field strength at the relative installation position meets the safe operation conditions of the network equipment; when the relative installation position is at The power frequency magnetic field intensity is greater than the safe operation threshold of the power frequency magnetic field intensity of the network equipment. It is estimated that the power frequency magnetic field intensity at the installation location does not meet the safe operation conditions of the network equipment.

一种具体的示例,以网络设备为5G通信设备为例。5G通信设备的工频磁场强度安全阈值为3.78ut。当5G通信设备在变电站所处安装位置的工频磁场强度小于安全阈值3.78ut时,则网络设备安全评估装置评估变电站该位置为5G通信设备的安全安装位置。当5G通信设备在变电站所处安装位置的工频磁场强度大于安全阈值3.78ut时,则网络设备安全评估装置评估变电站该位置为5G通信设备的不安全安装位置。A specific example is that the network device is a 5G communication device.

After that, the network equipment safety assessment device compares the power frequency magnetic field intensity with the safety threshold according to the installation location to evaluate the safety of the network equipment when installed at that location. In this way, when installing network equipment in a substation, the network equipment safety assessment device can use this method to evaluate the installation location where the power frequency magnetic field intensity meets the safety requirements from the installation locations in the substation that meet the network equipment installation location conditions, thereby making the network The equipment is installed at an installation location where the power frequency magnetic field strength meets safety requirements.

结合图2,如图3所示,上述步骤201具体还可以通过以下步骤301–步骤302中的一个或多个步骤实现。With reference to Figure 2, as shown in Figure 3, the above step 201 can also be implemented through one or more of the following steps 301 to 302.

步骤301、网络设备安全评估装置根据变电站设备的参数信息,确定变电站设备的电流值。Step 301: The network equipment security assessment device determines the current value of the substation equipment based on the parameter information of the substation equipment.

其中,参数信息包括:额定功率、额定电压以及功率因数角。Among them, the parameter information includes: rated power, rated voltage and power factor angle.

一种可能的实现方式中,变电站设备电流值的大小主要由变电站设备的额定功率、额定电压以及功率因数角来决定。因此,网络设备安全评估装置可以根据获取到变电站设备的额定功率、额定电压以及功率因数角来确定流过变电站设备的电流值的大小。In one possible implementation, the current value of the substation equipment is mainly determined by the rated power, rated voltage and power factor angle of the substation equipment. Therefore, the network equipment safety assessment device can determine the size of the current flowing through the substation equipment based on the obtained rated power, rated voltage and power factor angle of the substation equipment.

一种示例,变电站设备的电流值iab满足以下公式1As an example, the current value i ab of the substation equipment satisfies the following formula 1

其中,用iab为变电站设备的电流值来表示;P为变电站设备的额定功率;U为变电站设备的额定电压;为变电站的功率因数角。Among them, i ab is the current value of the substation equipment; P is the rated power of the substation equipment; U is the rated voltage of the substation equipment; is the power factor angle of the substation.

可选的,变电站设备的电流值还会受到变电站站点类别、电压等级、主变压器台数以及主容量等因素影响。Optionally, the current value of substation equipment will also be affected by factors such as substation site category, voltage level, number of main transformers, and main capacity.

一种示例,网络设备安全评估装置确定出变电站的类别、电压等级、设备类型、主变电站电压台数、主变容量等站点信息,并根据获得的站点信息建立变电站站点信息库。In one example, the network equipment safety assessment device determines the substation category, voltage level, equipment type, number of main substation voltage units, main transformer capacity and other site information, and establishes a substation site information database based on the obtained site information.

具体的,变电站的类别可划分为:枢纽变电站、终端变电站、升压变电站、降压变电站等;电压等级可以划分为:550V、220V、110V以及35V;设备类型可划分为变压器设备、开广场设备、电抗器设备以及日常办公设备;主变压器台数和主变容量根据站点的实际数据进行统计。Specifically, the categories of substations can be divided into: hub substations, terminal substations, step-up substations, step-down substations, etc.; voltage levels can be divided into: 550V, 220V, 110V and 35V; equipment types can be divided into transformer equipment and square equipment. , reactor equipment and daily office equipment; the number of main transformers and main transformer capacity are calculated based on the actual data of the site.

进一步的,为了更精确的模拟网络设备搭建区域范围内的工频磁场强度,网络设备安全评估装置根据变电站设备的类型,将变电站划分成四个搭建区域。其中,这四个搭建区域分别为:变压器区域、开关厂区域、电抗器区域以及日常办公区域。Furthermore, in order to more accurately simulate the power frequency magnetic field intensity within the network equipment construction area, the network equipment safety assessment device divides the substation into four construction areas according to the type of substation equipment. Among them, the four construction areas are: transformer area, switch plant area, reactor area and daily office area.

一种示例,如图4所示,为变电站开关厂区域的仿真模型示意图。在建立该仿真模型时,为了对内部细节进行优化,网络设备安全评估装置将母线、进线、出线和设备间相连的导线视为圆柱形导体。其中,导线为良导体。An example, as shown in Figure 4, is a schematic diagram of the simulation model of the substation switch plant area. When establishing the simulation model, in order to optimize internal details, the network equipment safety assessment device treats the busbars, incoming lines, outgoing lines and the wires connected between the equipment as cylindrical conductors. Among them, wires are good conductors.

需要说明的是,该仿真模型不考虑变电站内断路器、防雷器等电气设备对电磁场的影响。It should be noted that this simulation model does not consider the impact of electrical equipment such as circuit breakers and lightning arresters in the substation on the electromagnetic field.

值得注意的是,不同的搭建区域对变电站设备电流值的大小会产生不同的影响。在建立变电站工频磁场数据库时,网络设备安全评估装置会根据不同搭建区域的实际搭建环境自动设定影响设备电流值大小的影响参数。其中,实际搭建环境与搭建区域所处的变电站类别、电压等级等站点信息密切相关。在进行数据处理过程中,自动将公式1中获得的变电站设备电流值的大小转换成为变电站设备实际运行时的电流值的大小,该电流值仍用iab表示。It is worth noting that different construction areas will have different effects on the current value of substation equipment. When establishing the power frequency magnetic field database of the substation, the network equipment safety assessment device will automatically set the influencing parameters that affect the current value of the equipment based on the actual construction environment of different construction areas. Among them, the actual construction environment is closely related to the substation type, voltage level and other site information where the construction area is located. During the data processing process, the current value of the substation equipment obtained in Formula 1 is automatically converted into the current value of the substation equipment when it is actually running. The current value is still represented by i ab .

需要说明的是,本公开对影响参数的大小不作限定。It should be noted that this disclosure does not limit the size of the influencing parameters.
