101. the method comprises the following steps that a main machine of an information protection substation receives fixed value information of a protection device, wherein the main machine of the information protection substation is a remote acquisition terminal and is used for processing calling and transmission of the fixed value information;
the fixed value information is a protection fixed value, also called a protection setting value, which is a fault operation value preset in the protection device and is the core of the relay protection of the power system. Whether the protection constant value is accurate or not directly determines the rapidity and the correctness of the action of the protection device. The protection setting is generally matched with the operation mode of primary equipment of the power system, and the protection setting needs to be adjusted correspondingly when the mode is changed so as to adapt to possible fault conditions of the system.
In the embodiment of the application, the host of the information protection substation acquires the protection fixed value in the protection device operation fixed value area, the information protection substation is connected with an automation network in a transformer substation, acquires non-real-time information of the protection device and can perform fixed value acquisition on the information protection substation from the protection main station to the protection substation. Specifically, a communication state diagram of the protection device in the substation is checked in the information protection substation host through an existing automatic network in the substation, and the fact that the operation interval in the substation can normally communicate with the information protection substation host is confirmed. On the premise of ensuring normal communication, in order to realize the purpose of calling the protection fixed value through a remote command, a proper communication protocol needs to be selected, and fixed value information acquisition is carried out through the remote command specified in the communication protocol. In addition, a receiving picture of the fixed value information is established in the information substation system, and meanwhile, all operation interval names in the substation are added into the picture, so that the interval of the fixed value information needing to be collected can be selected; meanwhile, in a background program for calling the fixed value, a storage path of the fixed value information is written, and the path is separated from storage paths of other information files in the host of the information protection substation, so that other functions of the host of the information protection substation are not influenced.
102. The information protection substation host converts the fixed value information into a file type which can be checked and modified;
it should be noted that, after receiving the uploaded protection fixed value information, the protection substation needs to convert the fixed value model file uploaded by the protection device into a file type convenient for viewing and modification by using the protection substation host, and specifically, by establishing a graphical interface, the fixed value file is transferred to the graphical interface for processing, and each item in the fixed value information of the protection device is displayed as an independent entry, so that the fixed value modification is clear.
103. The information protection substation host modifies the fixed value information;
it should be noted that, the modification of the fixed value information of the protection device by the protection substation host is the fixed value modification performed by the secondary operation and inspection personnel according to the latest fixed value list issued by the setting department, and by using the fixed value management system, the secondary operation and inspection personnel can directly check the latest fixed value list and manually input the fixed value item to be modified into the collected fixed value list to complete the modification; the electronic version with the latest fixed value list can be imported into the insurance host, the changed fixed value items are automatically detected by the system, and the fixed value is automatically changed, and the method is not limited in the specific application.
104. And the information protection substation host sends the modified fixed value information to the protection device.

It should be noted that, due to the particularity of the protection constant value, the constant value information of the protection device needs to be collected again after the modification is completed, and the comparison check is performed with the last collected constant value information to ensure that the constant value information is successfully modified and is consistent with the latest constant value list. The specific comparison and inspection mode can display the comparison and inspection result in the acquired constant value information graphical interface, and the changed constant value items are marked by striking colors and fonts; a fixed value alarm window may also be established, and the changed fixed value items are directly displayed in the alarm window, which is not limited in the present application. For example, a fixed value alarm window is established, specifically, a fixed value comparison program is added in the system, a fixed value modification signal is added in the system alarm window, the fixed value comparison program automatically runs by calling the fixed value again, the fixed value is compared with the fixed value stored last time before the fixed value is stored, the changed fixed value setting item is displayed in the alarm window in the form of alarm information, and the comparison confirmation and result display of the fixed value information are completed.
