Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of centralized and distributed photovoltaic power stations, and particularly relates to a transmission method of point number data based on an electric power IEC104 protocol. BACKGROUND

[0002] The IEC104 protocol is an international standard widely used in the electric power and urban rail transit industries. The protocol transmits information between different electric power systems through defined information bodies. Each information body must define a unique address, which is commonly referred to as a "point number". Due to the large number of data points related to electric power systems, especially new energy electric power systems, the number of data collection points related to inverters is even larger. Different systems must agree on the same point number to communicate.

[0003] Therefore, new energy electric power systems, especially centralized photovoltaic power stations, involve a large number of inverters and require a large number of point numbers to be configured. The configuration workload is quite heavy for use and operation. SUMMARY

[0004] To solve the above problems, the present application provides a transmission method of point number data based on an electric power IEC104 protocol. The data points corresponding to the devices in the system are generated into the same file, and then the file is transmitted by section and segment through the IEC104 protocol. This avoids the heavy process of massive point number configuration. For centralized photovoltaic power stations, the scenario with a large number of devices can greatly reduce the operation and maintenance cost.

[0005] The first aspect of the present application provides a method of file transmission based on an electric power IEC104 protocol. The method is used for point number transmission between a master station and a slave station of field devices, and includes the following steps.

[0008] S103: Receive the point number data transmitted by section by the slave station.

[0009] S104: Check the point number data transmitted by the slave station. If the check is passed, send data information indicating successful reception, and jump to step S105. If the check is not passed, continue to jump to step 102.

[0018] Formula (1)

[0019] Meanwhile, the third point number data is multiplied by zero, if the adjacent data of the third data has no data pulse change, it represents that the section is the last device in the area, if:

[0020] Formula (2)

[0021] Meanwhile, the third point number data is multiplied by zero, and if the data pulse of the data adjacent to the third point number data changes, it indicates that the section is the end data of the region. The third point number data of the Nth section is represented by N3. The third point number data of the (N-1)th section is represented by N3.

[0022] The received data of all sections is accumulated to obtain second data, and the second data is compared with the first data of the number of region devices, and if the difference between the first data and the second data is zero, it indicates that the verification is correct, and data information indicating that the section has been successfully received is sent.

[0034] The accompanying drawings, which are incorporated herein and constitute part of the specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0035] Figure 1 The transmission method of point number data based on power IEC104 protocol disclosed in the embodiments of the present application is shown in the flowchart.

[0036] Through the above drawings, the specific embodiments of the present disclosure have been shown, and more detailed descriptions will be given hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present disclosure by any means, but to illustrate the concept of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is only one of the specific embodiments consistent with the present disclosure. Therefore, it is not intended to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0038] Information Object is a data object carried in transmission, which is a component of "meaningful service data" in communication messages. It is designed for consistent and standardized data representation and transmission between different power systems or devices. Operation and reliability are usually defined and organized by Information Object. Information Object is the core data carrying structure in power communication protocols, and is widely used in IEC 60870-5-104, IEC 61850 and other standards.

[0039] Select a unified communication protocol (such as IEC 60870-5-104, IEC 61850, DNP3, etc.), which defines the format and content of information objects. IEC 104: suitable for remote control / monitoring systems, information objects include telemetry, remote signaling, remote control, etc.

[0040] An information object usually consists of the following parts: Information Object Address (IOA): uniquely identifies the location of the data object in the device or system. Type ID: specifies the type of information object, such as telemetry value, remote signaling state, control command, etc. Cause of Transmission: indicates the reason for triggering the information (periodic, event, request response, etc.). Information Elements: actual data values or control instructions. As shown in Table 1.

[0041] Table 1

[0042]

[0043] Although the information object itself is used to transmit small data (such as voltage value, state quantity), if used to transmit files (such as configuration file, log), the following methods can be used: split the file by section / segment; each segment content is encapsulated into an information object, type identification is set to "file transmission" type; add segment number, total number of segments, check, etc. fields; the receiving end restores the complete file through the information object sequence.

[0044] The transmission method of point number data based on power IEC104 protocol generates the collection points of unified devices into the same file and transmits them through IEC104 protocol, which not only meets the requirements of power industry communication protocol, but also greatly reduces the configuration process of device point number, improves work efficiency, reduces operation and maintenance cost, especially in the scene of large number of centralized photovoltaic power station devices, which is particularly obvious.

[0045] In power systems, information communication based on point numbers (also known as data point numbers or information point numbers) is a common practice, especially in automation and monitoring systems. Point numbers are identifiers for specific data items of power equipment or systems, including device status, measurement values, alarm information, etc. Information communication usually relies on these point numbers to achieve data exchange and control instruction transmission between different devices.

[0046] In power automation systems, point numbers are used to identify and access various data related to system monitoring and control.

[0047] Usually composed of a series of identifiers, it can include: device identifier, used to identify the device or a specific part of the device, such as switch, circuit breaker, transformer, etc.; data type identifier, used to identify data types such as switch status (on / off), temperature, voltage, current, etc.; information point number, used to distinguish different data points of the same device, which is also a unique digital number or identifier.

[0048] Specifically, the point numbers in a certain substation may represent the following:

[0049] 10101, represents the switch status of the circuit breaker of the substation. 10202, represents the current measurement value of the substation. 10303, represents the temperature value of the transformer.

[0050] IEC 61850 is one of the commonly used standards in power automation systems, especially in substation automation. This standard organizes and describes different devices and information points by using data models (such as LNs – Logical Nodes) and object identifiers (Data Object).

[0051] Information points are represented by logical nodes and data objects, and each logical node may contain multiple data points, which are identified by uniform identifiers and communicated through standard communication protocols.

[0052] The specific steps of point number-based information transmission include:

[0053] The master station initiates a request, which can be a SCADA system, to request specific device status or measurement data from the device (such as substation equipment, relay protection device, remote terminal unit RTU, etc.).

[0054] The request includes a point number, indicating the specific data to be read or controlled.

[0055] After receiving the request from the slave device or RTU, the corresponding data item (such as the status of the circuit breaker, the measurement value of the current, etc.) is read or controlled according to the point number in the request.

[0056] The slave device returns data information related to the point number. If it is a control instruction, it returns the corresponding execution result. The information is transmitted through a power communication protocol (such as IEC 104, Modbus, DNP3, etc.). The communication protocol contains data fields, which contain point numbers and their corresponding data values. The data is transmitted to the master station through the network for monitoring, analysis, or decision support.

[0057] After the master station receives the data, it parses the relevant data according to the point number (for example, whether the switch state of the substation is "closed"). The master station performs corresponding operations such as alarm, control instruction (such as switch breaker, adjust voltage, etc.) based on these data.

[0058] The specific role of point numbers in communication includes state monitoring, measurement value acquisition, control instruction transmission, alarm and event monitoring.

[0059] In the state monitoring process, point numbers are used to identify and read the state information of power equipment (such as transformers, circuit breakers, switches, etc.), and to monitor the running state of the power system. For example, the master station obtains the switch state of all circuit breakers in the substation through the point number, and performs state analysis and remote control based on this information.

[0060] Point numbers are also used to identify various measurement values (such as current, voltage, power, temperature, etc.). The master station obtains these information through the point number, which is used for system load calculation, power flow analysis, and equipment health monitoring, etc.

[0061] Control instructions are transmitted through point numbers, such as sending "open circuit breaker" or "adjust transformer" instructions to remote devices through point numbers to achieve remote operation of power equipment.

[0062] Point numbers are also used to represent various alarm and event information (such as device failure, overload, overtemperature, etc.). Through the point number, the master station can identify the location of system failure and quickly respond to handle the failure or issue an alarm.

[0063] IEC 104 protocol is a commonly used power automation communication protocol that allows telemetry and remote control through point numbers. IEC 104 protocol transmits data in the form of messages, which contain point numbers (called "data object identifiers") that identify devices and data points. Each point number corresponds to a specific measurement data or control command, and the master station and slave station use this point number to exchange data during communication.

[0064] These protocols also have similar mechanisms that correspond each information point to a specific point number, which is used to identify device scheduling status or data during communication. For example, in the Modbus protocol, the data frame transmitted usually includes function code, address, and point number to distinguish different devices and data.

[0065] In general, the point number communication of the power system is based on the standard communication protocol for information transmission, each point number represents a specific data item (such as device status, measurement value, etc.), through the point number, the master station and the slave station carry out efficient information exchange and control in the power system. Of course, the point number is not only used for device status monitoring and data acquisition, but also involves remote control and transmission of alarm information, and is a basic element in the communication of power automation system. Through the standard point number management and communication protocol, the power system can realize efficient and reliable data exchange and control.

[0066] Especially when communicating data based on standard communication protocols, in the face of a large number of point number data, transmission according to sections or fields can help improve communication efficiency and ensure data transmission reliability, especially when a large amount of data or large files need to be transmitted, segmented transmission can also avoid communication interruption or data loss caused by too large data.

[0067] The point number data transmission method based on the power IEC104 protocol is used for point number transmission between the master station and the slave station of the field device, as shown in Figure 1 , comprising:

[0068] S101: Divide the field device by region, and number and count the same device in the same region to obtain first data related to the device in the region, and number the device data into the point number data.

[0069] Here, "section" or "field" refers to a data block or data unit, each section or field contains a certain number of point number data, which may be device status information (such as switch status), measurement value (such as current, voltage), alarm information, etc.

[0070] By dividing and transmitting the point number by section or field, the system can gradually send these data according to certain rules, and the master station and the slave station can confirm after each transmission is completed. Ensure the integrity and smooth transmission of data.

[0071] Determine the size of each section, for example, a section may contain 5 point number data, or adjust the data amount of each section according to system design, network bandwidth, etc. The size of the section needs to balance the communication efficiency and the reliability of data transmission.

[0072] A field can be regarded as a certain type of data set containing multiple point number data. For example, all point numbers about the status of circuit breakers can form a field, and all point numbers about the temperature of transformers can form another field.

[0073] Specifically, it is represented as: Section 1 (data section 1): contains point number 1 (circuit breaker status), point number 2 (current measurement), and point number 3 (voltage measurement).

[0074] Section 2 (Data Section 2): contains point number 4 (transformer temperature), point number 5 (generator state), etc.

[0075] Or according to the point number data type, it is divided into different fields, for example, all the state information (such as switch, circuit breaker state) forms a field, and all the measurement information (such as voltage, current) forms another field.

[0076] Or according to the device data or device type, the point number data is divided into sections, for example, the data of each transformer is transmitted as a byte, and the data of each circuit breaker is transmitted as another byte.

[0077] The field devices are divided by area, and the same device in the same area is numbered, and the data number is recorded in the point number data, including: according to the type of the device, the point number data in the same area is divided into sections, and the data number of the device in the area is recorded in the corresponding point number data.

[0078] Here, according to the device data method, different fields are divided. Specifically, first, all field devices are divided into regions, slices, and large code identifiers are performed, region 1, region 2, region 3... region N, and data definition is performed for the region, such as region 1 corresponds to 001, region 2 corresponds to 010, region 3 corresponds to 011,..., region 6 corresponds to 110. The data definition here is consistent with the subsequent node number data correspondence definition. Not limited to binary, decimal or hexadecimal data representation.

[0079] After defining the data area division of field devices, the point number data is divided into sections according to the type of the device in the region, such as all transformer data in region 3 forming a byte, all circuit breakers in region 3 forming a byte, all generators in region 3 forming a field, etc. All the working states of the generators in region 3 form a field.

[0080] The point number is divided into bytes and transmitted according to the following method. Specifically, the slave station sends a "section ready" instruction to the master station to inform the master station that the data of the section has been prepared and can start transmission. The instruction contains the identifier of the byte (section number, data type, etc.) and the size of the section.

[0081] Here, the data in each section is divided into several data segments for transmission. For example, section 1 might contain 10 point numbers, each point number potentially corresponding to a data segment. The master station receives the data for the entire section gradually through these data segments. Specifically, taking region 3 as an example, all transformer equipment in region 3 will also be numbered. For instance, transformer A in region 3 is represented as 0110001, transformer B as 0110010, transformer C as 0110011, and so on. The data number of the equipment in that region is recorded at the beginning of the section, the point number data in the middle of the section, and the last equipment number in the region at the end of the section. For example, region 4 has a total of 10 transformers; the point number data for the first nine transformers is represented as follows: The location number of the 10th transformer is represented as follows: This makes it easier to verify the data transmission integrity using the dotted data later.

[0082] During transmission, each data segment may contain one or more point numbers, which are transmitted through data segments defined by the protocol.

[0083] S102: The slave station sends a "file ready" request to the master station. This request includes data such as type identifier and transmission reason. The master station receives the slave station's "file ready" transmission request and replies. This includes receiving the slave station's "file ready" transmission request and replying that it accepts the transmission request.

[0084] After receiving the file transfer instruction from the master station, the slave station begins data transmission, which mainly consists of dotted data.

[0085] S103: Receive point number data transmitted section by section by the slave station. Receiving point number data transmitted section by section by the slave station includes receiving the first point number data. Second point data and the third point data .

[0086] S104: Verify the point number data transmitted by the slave station. If the verification passes, send data indicating successful reception and proceed to step S105. If the verification fails, proceed to step S102. This includes:

[0087] Based on the first point number data and the third point number data Verifying whether the data transmission is complete specifically includes:

[0088] According to the third point number data Determining whether all data for the device corresponding to this section has been transmitted includes:

[0089] Determine the Nth section With Section (N-1) addition, if the third data is 1, if

[0090] Formula (1)

[0091] Meanwhile, the third point number data is multiplied by zero, if the third data adjacent to the data has no data pulse change, it indicates that the section is the end device of the region, if:

[0092] Formula (2)

[0093] Meanwhile, the third point number data is multiplied by zero, if the third data adjacent to the data has no data pulse change, it indicates that the section is the end device of the region, if:

[0094] S105: transmission ends.
