[0045] See also Figure 1 , a certain embodiment of the present application provides a method for constructing relay protection operation and maintenance functions based on microservices. Figure 1 As shown, the microservice-based relay protection operation and maintenance function construction method includes steps S10 to S40. The specific steps are as follows:

[0046] S10, obtaining characteristic information corresponding to the intelligent relay protection device according to the intelligent substation SCD model;

[0047] It should be noted that the SCD model is a model that meets the specifications of the power industry's "GB / T 32890-2016 Relay Protection IEC61850 Engineering Application Model", "DL / T 860.73 Power Automation Communication Network and System Part 7-3: Basic Communication Structure-Common Data Class", "DL / T 860.73 Power Automation Communication Network and System Part 7-3: Basic Communication Structure-Compatible Logical Node Class and Data Class", "DL / T 1873-2018 Smart Substation System Configuration Description (SCD) File Technical Specifications", and "DL / T1874-2018 Smart Substation System Specification Description (SSD) Modeling Engineering Implementation Technical Specifications".

[0048] In a specific implementation, step S10 includes:

[0049] Get the manufacturer attribute of the relay protection manufacturer and the type attribute of the relay protection device under the IED tag in the SCD model, as well as the IP value of the relay protection network communication IP address and the IP-SUBNET value of the relay protection network communication subnet mask under the Address tag.

[0050] For example, in the SCD model, the model description of an IED is:

[0051] <IED desc="P_L12201A";

[0052] manufacturer = "GDNZ";

[0053] name="TEMPLATE" configVersion="V1.02" type="PSL-603UA5-N">.

[0054] The relay protection manufacturer is identified as "GDNZ" and the relay protection device model is "PSL-603UA5-N". The address model description is:

[0055] <address><P;

[0056] type="IP">172.20.20.1 <P;

[0057] type="IP-SUBNET">255.255.0.0 <P;

[0058] type="IP-GATEWAY">255.255.0.0 < / address> .

[0059] The relay protection network communication IP address is "172.20.20.1", and the relay protection network communication subnet mask is "255.255.0.0".

[0060] S20: Call the communication microservice application of the intelligent relay protection device according to the characteristic information. In a specific implementation, step S20 includes sub-steps S201 and S202. Figure 2 Specifically, the contents of each sub-step are as follows:

[0061] S201. Construct a communication microservice location identifier by using the manufacturer attribute of the relay protection manufacturer and the type attribute of the relay protection device model.

[0062] According to the relay protection manufacturer identification manufacturer attribute and the relay protection device model type attribute in the feature information in step S10, "relay protection manufacturer identification manufacturer attribute_relay protection device model type attribute_COM" is used to form a communication microservice positioning identifier.

[0063] S202: Match the communication microservice location identifier with the first character string of the intelligent relay protection device, and when the match is successful, call the registered communication microservice application.

[0064] According to the communication microservice positioning identifier in step S201, the communication microservice program pre-developed by the corresponding relay protection manufacturer, deployed in the system and registered in the service bus is called through the identifier string matching method.

[0065] In a specific embodiment, after executing step S20, the method further includes:

[0066] A communication connection with the protected device is established based on the relay protection network communication IP address IP value, the relay protection network communication subnet mask IP-SUBNET value and the communication microservice application in the characteristic information.

[0067] To help understanding, in a specific implementation, step S20 and the step of establishing a communication connection with the protected device are specifically described:

[0068] A) Based on the relay protection manufacturer identifier "GDNZ" and the relay protection device model "PSL-603UA5-N", the string "GDNZ_PSL-603UA5-N_COM" is composed as the location identifier of the communication microservice;

[0069] B) Normal operation in the plug-and-play system for relay protection operation and maintenance functions based on microservices The communication microservice program pre-developed by the corresponding relay protection manufacturer and deployed in the system has been registered in the system;

[0070] C) Compare the location identifier of the communication microservice with the microservice registration information in the system, and prioritize finding the communication microservice whose registration information and location identifier are consistent. If it cannot be found, search for the communication microservice whose registration information and the combination of the vendor identifier + COM ("GDNZ_COM") in the location identifier are consistent.

[0071] D) After locating the communication microservice, the communication microservice establishes a communication connection with the intelligent relay protection device using the relay protection network communication IP address "172.20.20.1" and the relay protection network communication subnet mask "255.255.0.0". The protocol used in the communication connection can be customized by the manufacturer of the intelligent relay protection device.

[0072] S30, based on the communication microservice application, generating a business model instance of the intelligent relay protection device according to the business model of the intelligent relay protection device and the fixed value data of the fixed value area;

[0073] It should be noted that, in this step, the fixed value data in the fixed value area is a model that describes all the fixed value data in all the fixed value areas of the intelligent relay protection.

[0074] Furthermore, the business model includes a secondary circuit link status patrol business model, a voltage and current circuit patrol business model, an input quantity patrol business model, a soft pressure plate status patrol business model, a fixed value patrol business model, a version verification business model, a longitudinal channel patrol business model, a device self-inspection patrol business model, a timing status patrol business model, a protection action diagnosis business model, a protection function patrol business model and a recording file channel information patrol business model.

[0075] As a specific implementation method, generating a business model instance of an intelligent relay protection device includes:

[0076] If it is a fixed value patrol business model, match the reference of the fixed value data of the fixed value area with the reference in the fixed value patrol business model, automatically configure the reference value attribute in the fixed value patrol business model, and generate the corresponding business model instance;

[0077] If it is other business models, it is directly used as the corresponding business model instance.

[0078] To help understanding, in a specific embodiment, the communication microservice is used to call the fixed value patrol business model and all fixed value area data inside the relay protection device as an example for explanation. By establishing a communication connection with the intelligent relay protection device, the communication microservice can call the fixed value patrol business model of the intelligent relay protection device and the data model of all fixed value areas of the intelligent relay protection. According to the reference mapping relationship between the fixed value patrol business model and the data model of the fixed value area, the data of the fixed value area is used as the reference value instance in the fixed value patrol business model to complete the instantiation of the fixed value patrol business model. The reference is composed of "ldInst+$+prefix+lnClass+lnInst+$+FC+$+doName+$+daName" in the SCD model, for example "PROT / LLN0$SE$DPFCStr$setMag$f".

[0079] S40. Call the operation and maintenance microservice according to the characteristic information, load the business model instance, and build an intelligent relay protection operation and maintenance function.

[0080] It should be noted that in this step, the operation and maintenance microservices include:

[0081] Secondary circuit link status patrol microservice, voltage and current circuit patrol microservice, input quantity patrol microservice, soft pressure plate status patrol microservice, set value patrol microservice, version verification microservice, longitudinal channel patrol microservice, device self-inspection patrol microservice, timing status patrol microservice, protection action diagnosis microservice, protection function patrol microservice and recording file channel information patrol microservice.

[0082] In a specific embodiment, step S40 includes sub-steps S401-S403, such as Figure 3 Specifically, the contents of each sub-step are as follows:

[0083] S401. Construct an operation and maintenance microservice location identifier according to the manufacturer attribute of the relay protection manufacturer and the type attribute of the relay protection device in the characteristic information.

[0084] In this step, according to the relay protection manufacturer identification manufacturer attribute and the relay protection device model type attribute in the feature information, the microservice location identifier is composed using "relay protection manufacturer identification manufacturer attribute_relay protection device model type attribute_operation and maintenance microservice label". The operation and maintenance microservice label is specifically shown in Table 1:

[0085] Table 1 Operation and maintenance microservice labels

[0087] S402: Match the operation and maintenance microservice location identifier with the second character string of the intelligent relay protection device, and when the match is successful, call the registered operation and maintenance microservice application.

[0088] According to the microservice positioning identifier described in step 4.1), the operation and maintenance microservice program pre-developed by the corresponding relay protection manufacturer, deployed in the system and registered in the service bus is called through the identifier string matching method.

[0089] S403: Use the operation and maintenance microservice application to load the business model instance and build an intelligent relay protection operation and maintenance function.

[0090] To help understand, in a specific implementation, the setting patrol microservice is used as an example. According to the relay protection manufacturer logo "GDNZ" and the relay protection device model "PSL-603UA5-N", and the setting patrol microservice label "SettingPatrol", the composition

[0091] The string "GDNZ_PSL-603UA5-N_SettingPatrol" is used as the location identifier of the setting patrol microservice;

[0092] In the plug-and-play system built based on microservices relay protection operation and maintenance functions, the fixed value inspection microservice program pre-developed by the corresponding relay protection manufacturer and deployed in the system is normally run. This communication microservice program has completed registration in the system;

[0093] By comparing the location identifier of the setting patrol microservice with the microservice registration information in the system, the setting patrol microservice with the registration information and location identifier that are consistent is preferentially found. If it cannot be found, the setting patrol microservice with the same string of the combination of the manufacturer identifier + the operation and maintenance microservice label ("GDNZ_SettingPatrol") in the registration information and the location identifier is searched;

[0094] After finding the corresponding fixed value patrol microservice, this service loads the fixed value patrol business instance model generated in step S30, thus completing the construction of the fixed value patrol business function, and the fixed value patrol microservice performs the fixed value patrol normally.

[0095] To summarize, the microservice-based relay protection operation and maintenance function construction method provided in the embodiment of the present application utilizes the manufacturer identification, device model, IP address, and subnet mask therein to locate the communication microservices and operation and maintenance microservices corresponding to the relay protection device that have been deployed in the system, and establish a communication connection with the relay protection, thereby realizing the calling and business model instantiation of the corresponding relay protection operation and maintenance business model and the set value area data, and realizing the construction of the relay protection operation and maintenance function by loading the instantiated business model through the operation and maintenance microservice, realizing the plug-and-play of the intelligent relay protection operation and maintenance function, and being able to support the rapid and automatic configuration and rapid deployment of relay protection in the construction of digital substations, meeting the requirements of shortening power outage time in modern construction.
