Description

Technical Field

[0001] The present application relates to the technical field of wind power generation, and in particular to a wind farm point table verification method and device based on a SCADA system. Background Art

[0002] my country is the world's largest energy consumer. Its energy structure has long been dominated by coal, and energy demand is growing rapidly. With dependence on foreign oil and gas continuing to rise, the task of promoting energy transformation is urgent. The Chinese government has introduced a series of policies to actively support this energy transition. With the continuous development of the wind power industry, wind farms are no longer constructed solely with a single type of wind turbine. To meet the rated capacity limits of wind farms, the integration of multiple wind turbine types into wind farms is becoming an inevitable trend.

[0003] Currently, one of the functions of a wind farm SCADA system is to monitor the operating status of each wind turbine in the wind farm. Monitoring wind turbine operation requires data point integration between the wind turbine controllers and the SCADA system. This means configuring a corresponding monitoring point table for each wind turbine controller in the wind farm SCADA system.

[0004] In related technologies, wind turbine monitoring point tables are typically imported manually or through semi-automated processes. The process of configuring the point table involves multiple, lengthy manual verifications. Due to the large number of point tables and the similarity of many monitoring point names, errors are inevitable during the verification process. If an incorrect point table is directly used in a wind farm SCADA system, some monitoring points will not be collected or stored, directly impacting the normal monitoring of the wind turbine and the collection of data for wind turbine operation data analysis. Conventional methods waste labor, are inefficient, and the results of the point table configuration review are still not guaranteed. Summary of the Invention

[0050] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of methods and apparatus consistent with certain aspects of the present application, as detailed in the appended claims.

[0051] The wind farm point table verification method based on the SCADA system provided in this application can be applied to Figure 1The application environment shown in the figure includes: a SCADA database server, wind turbine controllers, switches, hubs, routers, and terminals; each device is connected to the other via wired or wireless communication. Communication between these devices can be based on the Internet, a local area network, or a combination of the Internet and the local area network, which is not detailed here.

[0052] The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers and portable wearable devices. Figure 1 The example in FIG shows a case where there are two terminals, but the present application does not limit the number of terminals and may include more or fewer terminals. An application program is run on the terminal to implement a wind farm point table verification method based on a SCADA system.

[0053] Figure 2 The following is a flow chart showing a method for verifying a wind farm point table based on a SCADA system according to an exemplary embodiment. The method may include the following steps:

[0054] Step S1: Obtain the controller point table of each wind turbine and extract the actual information of the collection point;

[0055] Step S2: Obtain the point table configuration file of the SCADA system and extract the collection point configuration information;

[0056] Step S3: establishing a mapping model according to the collection point configuration information;

[0057] Step S4: using the mapping model, comparing the actual information of the collection point with the configuration information of the collection point;

[0058] Step S5: Outputting the difference between the actual information of the collection point and the configuration information of the collection point.

[0059] The solution of the present application can automatically review the configuration files of the SCADA system and the controller point tables of the wind turbine generator set to replace the lengthy manual review work, thereby greatly shortening the time required for the review work and improving the efficiency of the point table review work; avoiding the errors caused by the large number of point tables during the manual review process, effectively reducing the errors in the review process and improving the accuracy of the point table review.

[0060] It should be understood that although Figure 2 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. In addition, Figure 2At least part of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least part of the sub-steps or stages of other steps.

[0061] To further illustrate the technical solution of the present application, the solution of the present application is expanded and explained below in combination with specific application scenarios.

[0062] In order to ensure the high efficiency and accurate review of the wind power central monitoring system for each wind turbine point table configuration, the present invention provides a wind farm SCADA point table review method based on the Hash algorithm. The specific method is as follows: Figure 3 This method can improve the efficiency of point list review, reduce the number of review nodes, and improve the accuracy of point list review.

[0063] like Figure 4 and Figure 1 As shown, step S1 obtains the controller point table of each wind turbine generator set, which is obtained by the terminal from the PLC controller of the wind turbine generator set.

[0064] In some embodiments, the controller point table includes at least two columns of data: PLC point name and storage group; the actual collection point information includes at least PLC point name information and storage group information. The PLC point name is the measurement point name of the wind turbine; the storage group is the storage rule corresponding to the PLC point name.

[0065] Reference Figure 1 Each wind turbine has a PLC controller that collects data from each measurement point. A "PLC roll call" is the name of each measurement point. After data is collected, it is forwarded to the SCADA system for storage. Different storage methods are used for each measurement point, such as change storage, second storage, minute storage, hour storage, and so on. "Storage grouping" is the storage classification rule defined for "PLC roll calls."

[0066] like Figure 5 and Figure 1 As shown, step S2 obtains the point table configuration file of the SCADA system, which is obtained by the terminal from the SCADA database server.

[0067] Before step S2, it is usually necessary to manually configure the "PLC roll call" and "storage grouping" mentioned above to each wind turbine connected to the SCADA system. Since thousands of points need to be collected and stored, the configuration information needs to be checked after matching to find out whether there are any errors or omissions.

[0068] In some embodiments, the point table configuration file includes at least: a collection point configuration file and a storage point configuration file.

[0069] The collection point configuration file at least includes: a collection allocation table. The information in the collection allocation table includes: a number of PLC point names and their corresponding first configuration point names (POINT_NAME).

[0070] The storage point configuration file includes at least a storage allocation table and an intermediate classification table. The storage allocation table includes information about a plurality of second configuration point names (NAME) and their corresponding third configuration point names (ITEM_NAME). The intermediate classification table includes information about a third configuration point name (ITEM_NAME) and its corresponding storage rules. A mapping relationship between the first configuration point name (POINT_NAME) and the second configuration point name (NAME) is preset in the SCADA system.

[0071] In practice, SCADA systems have their own naming conventions for the measurement points they collect and store, which differ from the "PLC point names" described above. The collection and storage point configuration files mentioned above contain multiple columns of SCADA names. For example, in the collection configuration file, "POINT_NAME" corresponds to "PLC point name." The SCADA system internally converts "POINT_NAME" to "NAME." In the storage point configuration file, "NAME" is converted to "ITEM_NAME," and the measurement points corresponding to "ITEM_NAME" are then grouped for storage.

[0072] In some embodiments, the step S3 of establishing a mapping model according to the collection point configuration information specifically includes:

[0073] A one-to-one corresponding positive and negative Hash model is established according to the information in the point table configuration file.

[0074] The forward and reverse hash models are based on hash functions and are consistent with SCADA point table verification. Establishing one-to-one correspondence between the forward and reverse hash models involves creating a forward model for "PLC point name," "POINT_NAME," "NAME," and "ITEM_NAME," and a reverse model for "intermediate classification table" information and "storage grouping." This allows verification of point configuration errors and omissions during the data collection and storage stages.

[0075] In some embodiments, establishing a one-to-one correspondence between positive and negative hash models includes:

[0076] like Figure 6As shown, a forward model is established by mapping the PLC point name to the first configuration point name (POINT_NAME), the second configuration point name (NAME), and the third configuration point name (ITEM_NAME);

[0077] like Figure 7 As shown, a reverse model is established by mapping the information in the intermediate classification table to the stored group information.

[0078] As shown in Table 1 below, after the forward model is established, an unordered array is formed. The key is used as the index and the value is the corresponding value. The values ​​after different transformations can be quickly found.

[0080] key Value 1 Value 2 Value 3 PLC Roll Call 1 POINT_NAME1 NAME1 ITEM_NAME1 PLC Roll Call 2 POINT_NAME2 NAME2 ITEM_NAME2 …… …… …… ……

[0081] In some embodiments, comparing the actual information of the collection point with the configuration information of the collection point includes:

[0082] Compare the forward models to find the differences in the acquisition points;

[0083] By comparing with the reverse model, the storage point differences are found.

[0084] In some embodiments, the comparison using the forward model includes:

[0085] The PLC point names in the actual information of the collection points are searched in the forward model to find the collection points with differences.

[0086] Refer to Table 1 and use the PLC point name in the actual information of the collection point as an index to quickly find the corresponding various different names in the SCADA system, thereby finding whether there are any point configuration errors and omissions.
