The application integration of the power system is a necessary means for reducing workload, improving power quality and improving economic benefits of power enterprises, but the power enterprises are basically subjected to bar-block segmentation by depending on business departments in the informatization process, the application systems are mutually independent and highly autonomous, so that the problems of power grid modeling and inconsistent data names are serious, and the information matching is a problem which is urgently required to be solved by the application integration.
The problems are embodied as follows: in order to meet the requirements of various applications, a large amount of work needs to be carried out to verify whether the information is matched or not in the engineering debugging stage of the intelligent station. Similar to the work of monitoring information scheduling joint debugging of an intelligent station, verification of programmed operation in the station and the like, the work can be carried out manually one by one at present, a large amount of manpower and time are consumed, and the project progress is greatly influenced.
Disclosure of Invention
The invention aims to overcome the defects in the prior art, and provides an intelligent searching and matching method for the operation ticket information of the intelligent substation based on deep learning, which realizes automatic operation to replace the conventional manual operation mode and provides technical support for the work in actual engineering production and debugging.
In order to solve the technical problems, the invention adopts the technical scheme that: the intelligent searching and matching method for the operation ticket information of the intelligent substation based on deep learning comprises the following steps:
s1, extracting the operation object information in the operation ticket by using a keyword extraction technology;
s2, establishing a double-layer neural network model for intelligently searching and matching the operation ticket information;
and S3, extracting the DO object matched with the operation ticket information from the SCD file by utilizing similarity calculation and sorting.
In addition to the above technical solution, in step S1, the keyword extraction technique uses a word formation segmentation method based on a BP neural network model and uses a recurrent neural network model to identify the operation object in the operation ticket according to the segmentation result.
As a supplement to the above technical solution, in step S1, the word segmentation is performed by the word formation word segmentation method based on the BP neural network model, and the process is as follows:
selecting K characters before and after each character of the operation ticket, and inputting 2 x K +1 characters together with the character; selecting the vector dimension of each word as L, and inputting the dimension L (2X K +1) of the neural network model; adopting three layers of BP neural networks, wherein an input layer is provided with L (2 x K +1) neurons, a hidden layer is provided with L neurons, an output layer is provided with 4 neurons, the lexeme of each neuron corresponding to a character is respectively the probability of S, B, M and E, and the probability of S, B, M and E is respectively corresponding to the character to form a word, a word head, a word middle and a word tail; and selecting the word position with the highest probability from the output word position probability values as the word position category of the word.
In order to utilize the context information of each character of the operation ticket, the invention adopts a BP neural network in a knowledge-based word segmentation method to segment words. The method has good memory capacity of the context information of each word of the operation ticket and has good fault-tolerant effect; meanwhile, the method adopts a nonlinear parallel processing method, and can automatically process and learn the obtained knowledge and information in word segmentation, thereby solving the speed problem caused by more operation order information.
As a supplement to the above technical solution, in step S1, the recognition of the operation object in the operation ticket is realized by using the recurrent neural network model according to the word segmentation result, and the process is as follows:
sequentially converting the obtained word segmentation sequence into word vectors, and selecting the vector dimension of a word as M; setting a word number N with enough length, and filling the space behind the insufficient word number N, wherein the input of the cyclic neural network model is a vector of M x N and corresponds to an input layer of the cyclic neural network model; the second layer is a double LSTM (Long Short Term Memory Network); the output layer outputs 2-dimensional classification conditions, the output classification results are 0 and 1, whether the word is an operation object or not is represented, 0 represents no, and 1 represents yes.
In order to solve the problems of time sequence sensitivity of each word in the operation order and uncertain content length of the operation order, the invention adopts a Recurrent Neural Network (RNN) model.
In addition to the above technical solution, in step S2, the rule adopted for searching for matching is: judging whether the groups of the two pieces of information are the same or not, and if the groups of the two pieces of information are different, determining that the two pieces of information are not matched; and if the two pieces of information belong to the same group, judging whether the specific equipment information of the two pieces of information is the same or not, and giving a final matching result.
Since the general format of the line or device information in the operation ticket is "interval + specific device information". The degree of similarity between information of devices at the same interval is obviously high compared with different intervals. Thus, the present invention abstracts the intervals into groups.
In step S2, based on the search matching rule, a two-layer neural network model is used, and the first layer area is divided into an inner item and an outer item: the outside group is '0' and the inside group is '1'; the second layer distinguishes the matching term: the intra-group mismatch is '0' and the intra-group match is '1'; and the output of the model is the result of whether the operation order information is matched with the DO object in the SCD file.
As a supplement to the above technical solution, the double-layer neural network has four structures according to the difference of the neural network adopted in each layer, which are: BP _1, BP _2, the first, second layer which represents the model adopts BP model; BP _1 and LSTM _2, which represent that the first layer of the model adopts a BP model and the second layer adopts an LSTM model; LSTM _1 and BP _2, which represent that the first layer of the model adopts an LSTM model and the second layer adopts a BP model; LSTM _1 and LSTM _2 represent that the first and second layers of the model both adopt LSTM models.
As a supplement to the above technical solution, in step S3, according to the probabilities that the output result of the neural network in step S2 is '0' and '1', it is determined whether the operation order information matches all DO objects in the SCD file in a traversal manner; the probability of '1' is the similarity or the matching degree, and the size of the probability represents the matching degree of the operation ticket information and the SCD information, so that the DO object in the SCD file with the maximum matching degree is selected as the best matching result of a certain operation ticket information.
Compared with the prior art, the invention has the beneficial effects that:
(1) chinese word segmentation is realized by using a BP neural network.
(2) And the operation ticket keyword extraction is completed by utilizing the recurrent neural network.
(3) And the searching and matching of the operation order information are realized by utilizing a double-layer deep learning model (namely, a double-layer neural network model).
