An automatic checking method for a pressure plate of a 500 kV intelligent substation

Abstract

The invention relates to an automatic checking method for a pressure plate of a 500 kV intelligent substation. The concrete realization mode of the method comprises the following steps: setting control words for control according to different throw-back modes and vacancy elimination principles; developping the standard platen name database according to the relevant specifications of the State GridCorporation of China; analyzing the SCD file provided by the substation system integrator; calculating the similarity between the name of the platen in the standard library and the name of the platenin the SCD; performing manual selection and standardization of a small number of platens that are not automatically standardized or that do not match the standardization correctly; automatically generating the corresponding fault isolation strategy; setting the alarm level; actively reading the size of relevant parameters; according to the change of relevant parameter value, it is judged whetherthe primary equipment is in normal operation or power failure. when the power failure occurs, the program automatically adopts the corresponding power failure maintenance strategy. When it is in normal power-on state, it is judged whether the secondary maintenance pressure plate is in normal operation or not. to the method can achieve the automatic check of the platen state, to ensure the correctness of the platen throwing back the purpose.

Description

technical field [0001] The invention relates to the technical field of operation, maintenance and overhaul of secondary equipment in a 500kV intelligent substation, in particular to an automatic calibration method for a pressure plate of a 500kV intelligent substation. Background technique [0002] With the advancement of the modernization process, the progress of human civilization, the development of industry and agriculture, the demand for energy is increasing, and the demand for power resources far exceeds other energy sources. As the direct output mechanism of electric energy, the substation is directly related to the production of human industry and agriculture, and the safety management of the substation operation is more related to the safety of life and property of the masses, so it must be paid great attention by people. [0003] In the design of the current substation, there are usually various protection devices, and the protection pressure plate, also called the...

Problems solved by technology

Although many automated systems can monitor the real-time status and changes of these information, they cannot judge whether the changes are correct

Moreover, due to the inconsistency of the names of the pressure plates in different substations, the inactivated equipment and the different pressure plates when the defects are eliminated, it is impossible to use a set of general systems and methods to realize the automatic calibration of the pressure plates
