Transformer substation monitoring information control and check method

Abstract

The invention relates to the technical field of power grid dispatching, in particular to a transformer substation monitoring information control and check method, which comprises the following steps:A) inputting equipment information; B) establishing a software version application reference table and an association table; C) as the working data carries equipment information, and if the software version number is not input, refusing the working data, and giving an alarm; D) if the software version numbers are inconsistent, entering a step F; E) if both the parameter configuration table numberand the point table number are consistent, receiving the working data, otherwise, refusing the working data and giving an alarm; F) notifying telecontrol equipment to upload the latest table, comparing the latest table with the current table and the historical table, and if the comparison is passed, receiving the working data; and G) comparing the working data with the previous working data, if the format characteristics are consistent, receiving the working data, otherwise, establishing analogue simulation, and if the format characteristics are passed, receiving the working data, otherwise, rejecting the working data and giving an alarm, The transformer substation monitoring information control and check method has the beneficial effect that the correctness of each piece of working data can be ensured.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching automation, in particular to a control and verification method for substation monitoring information. Background technique [0002] With the rapid development of the power grid, the number of substations connected to the dispatching automation master station system is increasing, and the substations with voltage levels of 110kV and 35kV are gradually included in the scope of regulation, resulting in an increasing workload of operation and maintenance of substations. Ensuring the stable and reliable operation of substation automation equipment communication is related to power grid dispatching, as well as the correct analysis and judgment of the operating conditions of the power grid by monitoring and operating personnel, and the normal operation of functions such as state estimation, power flow scheduling, and static security analysis. The task is related to the security of the enti...

But its disadvantages are: 1. The information verification form is fixed. With the update of the device, the information verification form needs to be manually made. As a result, when the device is updated and upgraded, the manual needs to update the form on the device side and the dispatching master server. , reducing work efficiency, and allowing multiple humans to interact with the dispatching master station will reduce the data security of the dispatching master station; 2. The scheme uses periodic inspections of substations, and data errors that occur between two inspections cannot be found. low security
