It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The transmission method of the power quality monitoring data of the transformer substation can be applied to the application environment shown in fig. 1. The terminal 106 is arranged in the 5G base station, a 5G slice-type coding library is stored in a memory of the terminal 106, the communication between the power quality detector 102 and the terminal 106 is indirectly realized through the relay node 104, and power quality monitoring data acquired by the power quality detector 102 passes through the relay node 104 first and then is sent to the terminal 106 and the monitoring center 108 through the relay node 104. The power quality detectors 102 are installed on transmission lines of each segment of the substation, and devices such as the relay nodes 104 except the power quality detectors 102 are not directly connected to the lines of the substation, but are used for acquiring power quality monitoring data and are regarded as being indirectly connected to the substation. The terminal 106 obtains a type code of the equipment newly accessed to the substation, determines a corresponding 5G slice according to the type code, and transmits the power quality monitoring data to the monitoring center 108 according to the corresponding 5G slice.
Wherein the terminal 106 communicates with the monitoring center 108 via a network. The terminal 106 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the monitoring center 108 may be implemented by an independent server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for transmitting power quality monitoring data of a substation is provided, which is described by taking the method as an example for being applied to the terminal in fig. 1, and includes the following steps:
and step S202, acquiring the type code of the equipment newly accessed into the substation.
The equipment is used for obtaining power quality monitoring data of the transformer substation. The power quality monitoring data comprises power grid frequency, voltage deviation, three-phase voltage unbalance, public power grid harmonic wave, public power grid inter-harmonic wave, fluctuation and flicker, voltage sag and short-time interruption. The equipment for acquiring the power quality monitoring data in the transformer substation comprises a power quality detector. The electric energy quality detector can collect electric energy quality monitoring data of each section of the transformer substation. The monitoring center can be a server for collecting and analyzing the power quality monitoring data, and receives and analyzes the power quality monitoring data collected by the power quality detector.
Specifically, in one embodiment, before obtaining the type code of the device newly connected to the substation, the method further includes: the method comprises the steps of obtaining an access request of equipment newly accessed into the transformer substation, detecting whether the access request is legal access, responding to the access request when the access request is legal access, and executing the step of obtaining the type code of the equipment newly accessed into the transformer substation. The input format of the type code is a text, and the type code of the analysis equipment is converted into a character string form, so that the computer can conveniently identify the type code. For example, the type code of one power quality detector is a 'power quality detector', and when the access request of the power quality detector is legal, the terminal acquires the type code of the 'power quality detector', and converts the type code of the 'power quality detector' into a character string form from a text format. In one embodiment, when the type code of the device newly accessed to the substation is obtained, the method further includes checking whether the device newly accessed at present is consistent with the type code of the accessed device, when the type code is consistent, determining the number of the accessed devices with consistent type codes, and taking the number of the accessed devices as the number of the device accessed at present. Taking the Arabic numerals as an example, no matter which equipment is accessed into the substation, the number of the first equipment is 0. By means of the number, even if a plurality of devices under the same type have respectively unique identity information, namely the device number + type code. And determining the number corresponding to the equipment accessed into the transformer substation according to the maximum equipment number corresponding to each type of code.
And step S204, searching the type code in a pre-stored 5G slice-type code library, and determining a 5G slice corresponding to the type code.
The 5G slice-type code library is stored in a memory of the terminal in advance, and the corresponding relation between the type codes of various devices and the 5G slices is stored. Devices of the same class have the same type code, and a plurality of devices of the same class have different device numbers, which are stored in a memory.
Specifically, in the 5G slice-type code library, one type of code has one 5G slice. Each type of device has its own normally required minimum network requirements, which vary from one type of device to another. And searching in a 5G slice-type code library according to the type code, and determining the 5G slice corresponding to the type code, so that various devices can work under the required 5G slice.
And S206, transmitting the power quality monitoring data to a monitoring center according to the 5G slice.
The monitoring center receives the power quality monitoring data and is used for storing, analyzing and processing according to the power quality monitoring data.
In particular, the nature of 5G slicing is to configure a complete network into several sliced network configurations as needed. After the terminal searches and configures the corresponding 5G slice for the equipment, the power quality monitoring data acquired by the equipment is transmitted to the monitoring center according to the 5G slice.
In the method for transmitting the power quality monitoring data of the transformer substation, when a new device for obtaining the power quality monitoring data of the transformer substation is accessed, the device sends the corresponding type code to the computer device. After the computer device obtains the type code, searching in a pre-stored 5G slice-type code library according to the type code, and determining a 5G slice corresponding to the type code. And transmitting the power quality monitoring data to a monitoring center according to the 5G slice. According to different network requirements of each device of the transformer substation, different network slices are established, when the device of the transformer substation is accessed, the corresponding slices are automatically matched, 5G network resources are utilized to the maximum extent, and network resource waste is avoided, so that the utilization rate of the 5G network resources can be improved.
In one embodiment, the method for transmitting the power quality monitoring data of the substation further comprises the following steps: acquiring network requirements of various devices of a transformer substation; determining type codes corresponding to various devices according to the network requirements of the various devices; and setting a corresponding 5G slice for each type code, and obtaining and storing a 5G slice-type code library.
The equipment for obtaining the power quality monitoring data of the transformer substation comprises a relay node, a forward isolation device and a reverse isolation device besides a power quality detector and a monitoring center. These different kinds of devices have different corresponding network requirements.
Specifically, before determining the correspondence between the type codes of the various devices and the 5G slices, the network requirements of the various devices of the substation need to be collected and obtained, and the network requirements of the various devices are different, so that the corresponding 5G slices need to be designed in advance for the network requirements of the various devices. In one embodiment, the method includes the steps of acquiring network requirements of various devices of the substation, including acquiring a type code of a currently accessed device, checking whether the type code of the currently accessed device is acquired for the first time, storing the type code of the currently accessed device when the type code of the currently accessed device is acquired for the first time, and allocating a 5G slice to the currently accessed device. In order to distinguish various devices with different network requirements conveniently, when the network requirements of the various devices are obtained, the corresponding type codes can be determined for the various devices according to the network requirements of the various devices. Various types of 5G slices which are designed in advance are associated with various types of codes, so that a 5G slice-type code library can be obtained.
In this embodiment, network requirements of various devices of the substation are acquired, type codes corresponding to the various devices are determined, and corresponding 5G slices are set for the various types of codes, so that a 5G slice-type code library stored in the terminal can be acquired.
In one embodiment, the method for transmitting the power quality monitoring data of the substation further comprises the following steps: detecting the number of accessed devices in the substation; when the number of accessed devices in the transformer substation is larger than the preset number, reducing network parameters of 5G slices corresponding to non-core access devices in the accessed devices; when the number of the accessed devices in the transformer substation is not more than the preset number, increasing network parameters of 5G slices corresponding to the core access devices; the core access equipment is an electric energy quality detector; wherein the network parameter is a network configuration of a 5G slice.
Wherein the number of accessed devices is the number of all devices that have been accessed into the substation.
In particular, the terminal will usually detect the number of accessed devices in the substation, and the purpose of the detection is to optimize the network configuration of the core access device and the non-core access device according to the existing access number situation. When the number of the accessed devices in the transformer substation is detected to be larger than the preset number, the network parameters of the 5G slice corresponding to the non-core access devices in the accessed devices are reduced, namely, the network configuration of the non-core accessed devices is reduced. The preset number is the maximum number which ensures that the network quality of each accessed device of the transformer substation cannot begin to deteriorate.
And when the number of the accessed devices in the transformer substation is detected to be larger than the preset number, reducing the network parameters of the 5G slice corresponding to the non-core access devices in the accessed devices. Further, the network parameters of the 5G slice include a packet throughput rate, a packet forwarding delay, and a full packet discarding rate. Generally, the larger the packet throughput, the better the packet forwarding delay, and the closer the full-load packet drop rate to 0, the better. The network parameters for the 5G slice may be adjusted down to reduce packet throughput or increase packet forwarding delay. Furthermore, the non-core access device in the accessed device refers to a device other than the power quality detector, and adjusting down the network parameter of the 5G slice corresponding to the non-core access device in the accessed device refers to reducing the packet throughput, increasing the packet forwarding delay, or reducing the packet throughput and increasing the packet forwarding delay at the same time. When the network configuration of the non-core access device in the accessed device is reduced, the original normal network configuration of the core access device in the accessed device is correspondingly reserved or improved. In one embodiment, when the number of accessed devices in a substation is greater than a preset number, reducing network parameters of a 5G slice corresponding to a non-core access device in the accessed devices, wherein the non-core access device does not include a forward isolation device and a reverse isolation device. The network parameters of the forward isolation device and the reverse isolation device are not reduced because when the number of the accessed devices is too large, the more potential influencing factors on the power quality detection data are, the more physical isolation is needed to be safely carried out, and thus, the network parameter requirements on the forward isolation device and the reverse isolation device can only be increased and not reduced.
And when the number of the accessed devices in the transformer substation is not larger than the preset number, increasing the network parameters of the 5G slices corresponding to the power quality monitoring data of the core access devices. Furthermore, increasing the network parameters of the 5G slice corresponding to the core access device in the accessed device means to increase the packet throughput, decrease the packet forwarding delay, or both increase the packet throughput and decrease the packet forwarding delay. And then the quality of the ground network of the power quality detector is improved, so that the power quality monitoring data can be acquired more timely.
In this embodiment, by detecting the number of accessed devices in the substation, when the number of accessed devices is greater than the preset number, the network parameters of the non-core access devices in the accessed devices are reduced, the network configuration of the non-core access devices is reduced, and the network configuration of the core access devices in the accessed devices is stabilized. Or when the number of the accessed devices is not more than the preset number, the network parameters of the 5G slice corresponding to the core access device are increased. Thereby, the network configuration of the core access device and the non-core access device can be optimized.
In one embodiment, as shown in fig. 3, a processing system for substation power quality monitoring data includes a monitoring center 306, and a computer device;
the computer equipment is used for acquiring a type code of new equipment of a newly-accessed transformer substation, wherein the computer equipment is used for acquiring power quality monitoring data of the transformer substation; searching the type code in a pre-stored 5G slice-type code library to determine a 5G slice corresponding to the type code; wherein the 5G slice-type code library comprises type codes of various devices and corresponding relations between 5G slices; transmitting the power quality monitoring data to a monitoring center 306 according to the 5G slice; the monitoring center 306 acquires the power quality monitoring data, and performs identification analysis on the power quality monitoring data to obtain a power quality monitoring result.
The power quality monitoring result is obtained by analyzing the power quality monitoring data, and the power quality monitoring result contains information whether the power quality monitoring data needs to be compensated. The computer equipment is a terminal in a 5G base station.
Specifically, in one embodiment, before obtaining the type code of the device newly connected to the substation, the method further includes: the method comprises the steps of obtaining an access request of equipment newly accessed into the transformer substation, detecting whether the access request is legal access, responding to the access request when the access request is legal access, and executing the step of obtaining the type code of the equipment newly accessed into the transformer substation. The input format of the type code is a text, and the type code of the analysis equipment is converted into a character string form, so that the computer can conveniently identify the type code. For example, a type code of the power quality detector 102 is "power quality detector 102", and when an access request of the power quality detector 102 is legal, the terminal obtains a type code of "power quality detector 102", and converts the type code from a text format to a character string format. In one embodiment, when the type code of the device newly accessed to the substation is obtained, the method further includes checking whether the device newly accessed at present is consistent with the type code of the accessed device, when the type code is consistent, determining the number of the accessed devices with consistent type codes, and taking the number of the accessed devices as the number of the device accessed at present. Taking the Arabic numerals as an example, no matter which equipment is accessed into the substation, the number of the first equipment is 0. By means of the number, even if a plurality of devices under the same type have respectively unique identity information, namely the device number + type code. And determining the number corresponding to the equipment accessed into the transformer substation according to the maximum equipment number corresponding to each type of code.
In the 5G slice-type code library, one type of code has one 5G slice. Each type of device has its own normally required minimum network requirements, which vary from one type of device to another. And searching in a 5G slice-type code library according to the type code, and determining the 5G slice corresponding to the type code, so that various devices can work under the required 5G slice. For the power quality detector 102, when entering the network through a default (initialization) slice, the 5G slice corresponding to the power quality detector 102 is determined according to the type code of the power quality detector 102.
The nature of 5G slicing is to configure a complete network into several sliced network configurations as needed. After the terminal searches and configures the corresponding 5G slice for the device, the power quality monitoring data acquired by the device is transmitted to the monitoring center 306 according to the 5G slice.
In this embodiment, when a new device for obtaining power quality monitoring data of a substation is accessed, the device may send a type code corresponding to the new device to the computer device. After the computer device obtains the type code, searching in a pre-stored 5G slice-type code library according to the type code, and determining a 5G slice corresponding to the type code. And transmitting the power quality monitoring data to a monitoring center according to the 5G slice.

Wherein the 5G slices include a first 5G slice, a second 5G slice, and a third 5G slice. The first 5G slice is a communication network when the power quality monitoring data is transmitted between the power quality detector 102 and the relay node 302, the second 5G slice is a communication network when the power quality monitoring data is transmitted between the relay node 302 and the forward direction isolation device 304, and the third 5G slice is a communication network when the power quality monitoring data is transmitted between the forward direction isolation device 304 and the monitoring center 306. The first 5G slice, the second 5G slice, and the third 5G slice differ in network configuration due to the different device types.
For the relay node 302, in an embodiment, when the relay node 302 enters the network through a default (initialization) slice, the access number of the power quality detector 102 and the type code of the relay node 302 are obtained, and the 5G slice corresponding to the relay node 302 is determined according to the access number and the type code.
For the forward isolator 304, when the forward isolator 304 enters the network through a default (initialization) slice, the terminal determines a corresponding 5G slice for data transmission of the forward isolator 304 according to the type code of the forward isolator 304. For example, the specific setting may be that the throughput of the data packet is greater than or equal to 40Mbps (100 security policies, 1024 byte message length) in a hundred megabyte state, the data packet forwarding delay: < 10ms (100% load), 5G slice with a full packet drop rate of 0. The forward isolation device 304 physically isolates the power quality monitoring data from the relay node 302 to the monitoring center 306, and since substantially all the power quality monitoring data need to be finally transmitted to the monitoring center 306 after being collected by the power quality detector 102, the data volume is large, the throughput of the data packet of the forward isolation device 304 needs to be as large as possible and the delay needs to be as small as possible, so that the forward isolation device 304 is beneficial to improving the data transmission security when physically isolating a large amount of power quality monitoring data.
In this embodiment, by setting the forward isolation device, good physical isolation can be performed in the process of transmitting a large amount of power quality monitoring data from the relay node to the monitoring center, so that the security of transmitting the power quality monitoring data is improved.
In one embodiment, the 5G slice further includes a fourth 5G slice, and the apparatus further includes a reverse isolation device 308, configured to reversely transmit the power quality monitoring data of the monitoring center 306 to the relay node 302 according to the fourth 5G slice.
When the monitoring center 306 finds that some power quality monitoring data are abnormal, or detects some power quality monitoring data according to the user requirement, the reverse isolation device 308 may perform reverse isolation on the power quality monitoring data transmitted from the monitoring center 306 to the relay node 302.
For the reverse isolation device 308, when the reverse isolation device 308 enters the network through a default (initialization) slice, the terminal determines a corresponding 5G slice for data transmission of the reverse isolation device 308 according to the type code of the reverse isolation device 308. For example, the specific setting may be 5G slice that the effective network throughput rate of the ciphertext in the hundred mega state is greater than or equal to 20Mbps, the digital signature rate is greater than 60 times/second, the data packet forwarding delay is less than 30ms, the full-load data packet discarding rate is 0, the delay is less than 10ms (100% load), and the full-load data packet discarding rate is 0. The amount of power quality monitoring data that needs to be reverse isolated using reverse isolation device 308 is much less than the amount of power quality monitoring data that needs to be forward isolated using forward isolation device 304. Thus, in terms of packet throughput, the forward isolation device 304 is larger and the reverse isolation device 308 may be relatively smaller; the forward isolation device 304 is smaller in terms of packet forwarding delay and the reverse isolation device 308 may be relatively larger.
In this embodiment, through setting up reverse isolating device to can carry out reverse isolation to power quality monitoring data.
In one embodiment, the system further includes a power quality server 310, configured to determine whether the power quality monitoring data needs to be compensated according to the power quality monitoring result, and when the power quality monitoring data needs to be compensated, compensate by using a corresponding control method.

Specifically, the power quality server 310 may determine whether the power quality monitoring data needs to be compensated based on the power quality monitoring result. And when the power quality monitoring result indicates that the power quality monitoring data needs to be compensated, compensating the power quality monitoring data by adopting a corresponding control method to obtain an ideal compensation effect. And when the power quality monitoring data does not need to be compensated according to the power quality monitoring result, the subsequent compensation operation is not executed.
