Problems solved by technology

The fixed value setting is applicable to various load levels. Therefore, it is necessary to repeatedly adjust and try to obtain the cut-off amount under each load level of the tidal current file and the stability file. The fixed value setting adjustment workload is very heavy, and manual adjustment speed and accuracy cannot meet more urgent needs

Abstract

The invention discloses a constant value setting method, device, equipment and storage medium of a power system. The initial power flow file is divided into different parts according to the load point information of the initial power flow file, and the different parts contain different information of the power flow file, which can It is convenient to adjust different information of the trend file, and re-merge the different parts of the initial trend file after adjustment to obtain a new trend file; according to the initial trend file and the new trend file, adjust the initial stable file to obtain a new stable file. The new power flow file and the new stability file are used to calculate the stability of the power system, obtain the stability calculation results, generate the fixed value setting scheme of the power system, and adjust the power system according to the generated fixed value setting scheme, which can maintain the stability of the power system. The method can quickly generate required calculation files, greatly speed up the setting speed, and improve the setting quality.

Description

technical field [0001] The invention relates to the technical field of power system constant value setting, in particular to a power system constant value setting method, device, equipment and storage medium. Background technique [0002] In recent years, with the interconnection of the power system, the scale of the power system is increasing, and the possible stability problems are also increasing. It is necessary to use the stability control technology to ensure the stable operation of the system. The key to realizing this technology is the stability control device. [0003] The stability control device can act to cut off the abnormal load or abnormal unit under the abnormal condition of the power system to ensure the stability of the system, and has the advantages of strong pertinence and high reliability. However, the process of the stability control device to maintain the stability of the system depends on the constant value tuning, which requires the use of simulation...
