Abstract:In order to solve the problem that the existing regional power grid in Guiyang centralized monitoring system parameter maintenance tools are inefficient, high error rate, and can meet the ergonomic requirements of massive parameter maintenance in the integrated operation mode of power grid dispatching and supervisory control for the specialty of power grid dispatching automation, the paper is based on the intelligent system for integrated grid operation (OS2) standard of China Southern Power Grid Corporation, and combined with the characteristics of warning information description of the integrated system of power grid regulation and control in Guiyang. By structuring the description of alarm information and extracting effective keywords from it, a description specification of digital and analog quantities for computer intelligent recognition is compiled. Based on this specification, an intelligent guide library tool is exploited, which can automatically fill in the parameters threshold of original point list and import the parameter library efficiently and correctly.It solves the problem of low efficiency and high error rate of parameter inputting caused by excessive manual operation, and then compares the efficiency of the original parameter maintenance tool with that of the intelligent guided library tool through the experiment of equal parameter guided library processing, verifies the practicability of the specification, and prospects the further improvement of the intelligent guided library tool.
