Abstract

The invention discloses a new method and device for main station and substation channel selection of a dispatching automation system, and belongs to the technical field of dispatching automation. The method is characterized by comprising the following steps: obtaining evaluation values of n main station and substation data transmission channels on m data evaluation indexes; carrying out standardization processing on the evaluation index matrix, and further determining an evaluation index weight; determining the quality of the data transmission channel of each main station and each substation; and selecting the main station and substation data transmission channel with the optimal channel quality as the finally selected main station and substation data transmission channel. According to the invention, the channel quality can be accurately and comprehensively evaluated, the channel with high data quality is preferentially adopted, the data quality between the main station and the substation is guaranteed, and the situation that normal operation of the system is threatened by decisions made according to bad data is avoided.

Description

technical field [0001] The invention relates to a new method and device for channel selection of a main substation of a dispatching automation system, belonging to the technical field of dispatching automation. Background technique [0002] The improvement of the degree of automatic control of the power system makes the operation and control of the power grid more dependent on data. Therefore, the collection and utilization of informatization data in modern society plays an important role in power operation and production, and plays an irreplaceable role in production operation and management. High-quality data is also an important guarantee for high-quality decision-making of enterprise users. In addition, in the actual operation of the power system, there are situations where channel transmission data is lost or contains erroneous data, which will have a great impact on the operation of the power grid, not only affecting the overall software performance of the system, but ...
