A 500kv intelligent substation pressure plate automatic calibration method

Abstract

The invention relates to an automatic checking method for a pressure plate of a 500kV intelligent substation. The specific implementation methods of this method include: setting control words for control according to different input and withdrawal methods and defect elimination principles; formulating a standard pressure plate name library according to the relevant specifications of the State Grid Corporation; analyzing the SCD file provided by the substation system integrator; calculating the standard library The similarity between the name of the pressure plate in the SCD and the name of the pressure plate in the parsed SCD; standardize the manual selection of a small number of pressure plates that cannot be automatically standardized or the standardization is not matched; automatically generate the corresponding fault isolation strategy; set the level for the alarm; read actively Relevant parameter size; according to the change of relevant parameter values, it is judged whether the primary equipment is in normal operation or power outage, the program automatically adopts the corresponding power outage maintenance strategy when the power is off, and then judges the state of the secondary maintenance pressure plate when it is in the normal power on state. In this way, the purpose of automatically checking the state of the pressing plate to ensure the correctness of the pressing plate’s throwing and withdrawing is realized.

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 checking method for a pressure plate of a 500kV intelligent substation. Background technique [0002] With the advancement of modernization, the progress of human civilization, and the development of industry and agriculture, human demand for energy is increasing, and the demand for power resources far exceeds other energy sources. As a direct output mechanism of electric energy, substation is directly related to the production of human industry and agriculture, and the safety management of substation operation is more related to the life and property safety of the masses, so people must pay great attention to it. [0003] In the current design of substations, protection devices with various functions are usually equipped, and the protection pressure plate, also called the protection...

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
