A power grid start-up operation ticket generation device and method based on natural language processing

Abstract

The invention discloses a power network start-up operation ticket generating device and method based on natural language processing. The device comprises: a Chinese word segmentation and part-of-speech tagging module, which is used for extracting sentence structure of instruction sentence in input start-up scheme through word segmentation and part-of-speech tagging combined with a power network dictionary. A named entity recognition and relationship extraction module, which is used for identifying the operating equipment and the equipment state of the extracted instruction statement through the named entity, further analyzing the instruction statement according to the result of the part-of-speech tagging, establishing the attribute relationship between the operating equipment entity and the equipment state, and establishing the entity relationship of different instruction statements; The start-up scheme generation module is used for obtaining the key information of the start-up operation order statement according to the relevant prior knowledge and rules in the power network field, and generating a standard start-up operation order. The invention can reduce the employment cost of an enterprise and the influence of human error on the start-up operation order compilation, thereby ensuring the safe and stable operation of the power network.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a device and method for generating an operation ticket for power grid start-up based on natural language processing. Background technique [0002] The operation ticket is a paper record that must be completed before the operation of the electrical equipment. It requires the operator to fill in the operation steps step by step according to the task requirements, combined with the on-site equipment and equipment operation conditions, and then implement it according to the operation ticket. It is an important technical measure to ensure the safe production of electric power. [0003] The operation ticket system is one of the important measures to ensure the safe operation of the power grid. Under the background of the current smart grid construction, the current operation ticket system has begun to gradually become automated and intelligent. [0004] For some b...

AI Technical Summary

Problems solved by technology

[0006] 1. The instruction sentences in the startup plan are relatively colloquial and non-standard

[0007] 2. Lack of standard names and initial states of grid equipment

[0008] 3. Part of the instruction format in the startup plan may be irregular or even wrong (human error)

[0009] Faced with these problems, even for experienced power grid dispatchers, it is still quite cumbersome to issue a start-up operation ticket, and due to the complexity of the instruction sentences of the start-up operation ticket, human errors are very likely to occur in the process of writing the operation ticket , thus further affecting the safe operation of the power grid

[0010] Aiming at the problem of automatic generation of start-up operation tickets by the start-up plan, due to the complexity of the problem and limited by the development of technology, the current main technical means is to rely on professional grid dispatchers to manually write the start-up operation tickets. Low efficiency, waste of labor costs, and secondly, it is difficult to avoid human error, which affects the safe operation of the power grid. Therefore, it is necessary to propose a technical means to solve the above problems
