[0047] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine with the drawings in the present invention to further explain the method, system, computer equipment and storage medium for accessing the main station for verification of substation monitoring information based on data baseline proposed by the present invention.

[0048] Embodiment 1:

[0049] This embodiment proposes a method for verifying substation monitoring information access to a master station based on a data baseline, including the following steps:

[0050] The sender's master station system collects substation monitoring information in real time;

[0051] The sending master station system performs homologous feature extraction on the substation monitoring information collected in real time to obtain feature data of the substation monitoring information; homologous feature extraction, for example, satisfies: the substation ID, channel ID, telemetry type, point number range, reasonable value upper and lower limits, and the status is normal and belongs to the same data.

[0052] The sending master station system uniformly describes the key information in the characteristic data of the substation monitoring information according to a pre-set serialization structure to form a substation incremental signal; the key information mentioned in this embodiment includes but is not limited to the acceptance plant, communication channel, signal type and point table information; therefore, the corresponding pre-set serialization structure is a structure in the order of acceptance plant, communication channel, signal type and point table information.

[0053] The sending master station system verifies the substation incremental signal with the data baseline pre-stored in the data baseline library to obtain the verification result, which includes normal monitoring information and abnormal monitoring information;

[0054] The sending master station system pushes the substation incremental signal with the verification result that the monitoring information is normal to other receiving master station systems for verification. The specific operation is: the sending master station system pushes the substation incremental signal with the verification result that the monitoring information is normal to other master station systems through the wide area service bus, and other receiving master station systems obtain the substation incremental signal with the verification result that the monitoring information is normal through the wide area service bus.

[0055] For any receiving master station system, after receiving the substation incremental signal pushed by the sending master station system, it is verified with the data baseline pre-stored in the data baseline library to obtain the verification result; and the verification result is sent to the sending master station system.

[0056] The data baseline library mentioned in this embodiment is constructed according to the following steps:

[0057] Extract features from existing substation monitoring information to obtain feature data;

[0058] The key information of the feature data is uniformly described according to the pre-set serialization structure to form a data baseline library.

[0059] This embodiment uses a set of master station systems to complete the verification of the substation incremental signal, pushes information, and conducts consistency comparison of substation monitoring data and communication channels and sharing of verification results among multiple master station systems based on the substation incremental signal, thereby achieving the goal of one set of master station system verification and multiple systems synchronous verification, and improving the accuracy and efficiency of data verification.

[0060] Embodiment 2:

[0061] This embodiment proposes a method for verifying substation monitoring information access to a master station based on a data baseline, which mainly includes the following steps:

[0062] Step 1: Establish a data baseline library to store the data baseline of substation monitoring information; the data baseline library in this step is constructed according to the following steps:

[0063] S1_1: Utilizing the correlation and complementarity of multi-source data of substation monitoring information and based on the subspace learning method, the existing substation monitoring information is subjected to dimensionality reduction, feature extraction, data representation and classification processing, and key feature information such as acceptance plant, communication channel, signal type, point table information, etc. is projected into the middle-level redundant feature isomorphic space. The middle-level redundant feature isomorphic space refers to an intermediate level space obtained through learning, which is used to bridge multiple heterogeneous underlying feature spaces and high-level semantic shared subspaces. In this embodiment, it refers to the upper-level master station system.

[0064] S1_2: Standardize the substation monitoring information according to the acceptance plant, communication channel, signal type and point table information, that is, uniformly represent the homologous data in the substation monitoring information and add data tags. The purpose of adding data tags is to give the monitoring information a mark. When the mark is sent to the master station system, the master station system can distinguish it according to the mark and quickly identify the data source and characteristics;

[0065] S1_3: In the middle-level redundant feature isomorphic space, a baseline library of data feature sets is formed according to the data flags sent by the substation. Subsequently, based on the data baseline library, the semantic consistency between the isomorphic descriptions in the middle-level redundant feature isomorphic space is fully explored to achieve synchronous verification and automatic signature verification of homologous data, which is convenient for reference in subsequent verification.

[0066] Step 2: Build a wide-area distributed message transmission framework. Under this wide-area distributed message transmission framework, by formulating multi-channel data access, message subscription, parallel transmission methods and strategies, the substation monitoring information and interactive instructions can be pushed and the results shared between the dispatching system and the centralized control system. Figure 2 As shown, in the wide-area distributed message transmission framework, information push and result sharing are performed between the centralized control system and the dispatching system. The specific operations include:

[0067] S2_1: The centralized control system and the dispatching system obtain the channel network, point table information and request commands of the opposite system through the wide area service bus, so as to realize the connection between the centralized control system and the dispatching system;

[0068] S2_2: The centralized control system sends a request command to the dispatching system. After receiving the request from the local system, the centralized control system transmission service forwards it to the dispatching system transmission service through the wide area service bus;

[0069] S2_3: After receiving the request, the dispatching system returns a confirmation result. The centralized control system determines whether the request is successful or failed by judging the returned result.

[0070] S2_4: After receiving the substation data message, the dispatching system pushes the substation telemetry and telesignaling change data to the opposite side centralized control system according to the protobuf general message structure, so as to realize the information interaction between the dispatching system and the centralized control system.

[0071] Step 3: By improving the model mapping rules, a unique mapping relationship between the device ID in the dispatching system and the device ID in the centralized control system is established; specifically, first read the device information under the same plant station of the centralized control system and the dispatching system, which includes but is not limited to the leading point number of the device and the Chinese name of the device, and then calculate the matching degree of the device information of the centralized control system and the device information of the dispatching system based on the similarity algorithm according to the leading point number of the device and the Chinese name of the device, and sort them from high to low according to the matching degree. The device information with a low matching degree is manually confirmed, and finally the device ID mapping of the centralized control system and the dispatching system is completed;

[0072] Step 4: The centralized control system collects substation monitoring information in real time or regularly. Specifically, the centralized control system connects to the substation through a separate communication channel, receives forwarding messages and obtains source tags. Information collection is the key link for substation monitoring information to access the master station system. According to the pre-established collection tasks, the corresponding collection parameters are configured to collect substation monitoring information regularly or in real time. The substation monitoring information includes telemetry data, telesignaling status, etc. The collected substation monitoring information is preprocessed. The preprocessing content includes deviation processing, missing filling, invalid filtering, etc. The preprocessing steps include data cleaning, data conversion, data aggregation, etc. The centralized control system identifies the collected data (communication channel, signal type, point table information of the substation) according to the homologous characteristics of the substation monitoring information in the same communication channel to obtain feature data. A substation will send data to the master station system through multiple channels, and the data of each channel may be different, so it is necessary to distinguish according to each channel. Finally, the key information of the feature data is uniformly described in detail through the serialization structure to form substation incremental information, which provides data support for the subsequent multi-target master station synchronization acceptance.

[0073] In this step, corresponding collection parameters including but not limited to collection frequency, collection depth and filtering conditions are configured to ensure that the collected data can meet the requirements of system access and reduce unnecessary data redundancy and interference information as much as possible.

[0074] Step 5: The centralized control system compares the substation incremental information with the data baseline in the data baseline library to determine whether the collected data is within the normal range. If the collected data exceeds the normal range, an abnormal alarm is issued and the abnormal data item, abnormal time, abnormal cause and other information are recorded.

[0075] Step 6: After the centralized control system completes the access acceptance of the substation incremental information, it pushes it to the dispatching system based on the wide-area distributed message transmission framework to complete the cross-domain sharing of the verification results of the same source signal and the same channel of the same substation. The dispatching system subscribes to the synchronization message of the verification result of the centralized control system and performs data deserialization and parsing operations to obtain the integrity description of the substation incremental information, and conducts comparison and verification based on the substation incremental information to confirm the consistency of the substation incremental signal and communication channel for sharing the acceptance results, thereby achieving the goal of one system acceptance and multiple system synchronous verification.

[0076] Step 7: Obtain the verification results from the centralized control system and the dispatching system, and generate a joint test report in a fixed format. The report content includes abnormal data items, abnormal time, abnormal causes and other information, and is displayed through the interface for user viewing and management.
