Problems solved by technology

Since there is a safety isolation device between the safety area III and the safety area II, the relay protection setting data cannot be directly transmitted from the safety area III to the online checking system of the relay protection setting in the safety area II
At present, the existing technology mainly re-enters the relay protection setting data in the safety area II, or manually copies the relay protection setting data of the safety area III to the safety area II, which is not only inefficient, but also cannot guarantee the relay protection setting The value online checking system checks the relay protection fixed value data in time, thus affecting the timeliness of relay protection

Embodiment 1

[0027] This embodiment provides a method for processing relay protection fixed value data, see figure 1 , the method includes:

[0028] Step 101, acquire the first relay protection fixed value data from the fixed value database located in the safe zone III at a preset period.

[0029] The first fixed value data of relay protection is data that needs to be acquired and checked, and is stored in the fixed value database located in the safe area III. The first relay protection fixed value data can be obtained regularly by configuring the export program, and the process of obtaining the first relay protection fixed value data by the export program according to the preset cycle is as follows:

[0030] Configure the export program in the safety zone III; set the export program, including setting the time period, then the export program will regularly obtain the first relay protection fixed value data from the fixed value database according to the set cycle, and will obtain the firs...

Embodiment 2

[0048] This embodiment provides a method for processing relay protection fixed value data in combination with specific configurations, see figure 2 , the method includes:

[0049] Step 201, configure the export program on the server storing the fixed value protection data in the safety zone III.

[0050] Step 202, the export program obtains the first relay protection fixed value data at a preset period, and stores it locally.

[0051] The obtained first relay protection fixed-value data includes principle-level data and device-level data. The principle-level data is fixed-value data for a certain grid element using a certain protection principle, and is not limited to a certain manufacturer, a certain Model of the device, with universal adaptability. Principle-level data includes line principle-level data and transformer principle-level data, among which, line principle-level data includes phase-to-phase distance I, II, and III sections, grounding distance I, II, and III se...

Embodiment 3

[0067] refer to image 3 , gives a system structure diagram of relay protection fixed value data processing according to the third embodiment of the present invention.

[0068] The system of relay protection fixed value data processing of the present invention comprises:

[0069] The derivation module 310 is used to obtain the first relay protection setting value data from the setting value database located in the safe zone III according to the preset period, and store it in the preset position;

[0070] The uploading module 320 is used to call a command to upload the first relay protection fixed value data derived by the deriving module to the transmission server in the safe III area;

[0071] The transmission server 330 is configured to encapsulate the received first relay protection fixed value data to generate second relay protection fixed value data, and send the second relay protection fixed value data to the reverse isolation device;

[0072] The reverse isolation dev...

Abstract

The invention discloses a method and system for processing relay protection definite value data. The method comprises the steps that first relay protection definite value data are obtained from a definite value database located in a safety area III according to the preset period; an instruction is called to upload the first relay protection definite value data to a transmission sensor in the safety area III; the transmission sensor packages the received first relay protection definite value data to generate second relay protection definite value data, and transmits the second relay protection definite value data to a reverse isolation device; the reverse isolation device verifies the received second relay protection definite value data, if verification fails, the follow-up steps stop executing, and if verification is successful, the second relay protection definite value data are pushed to a checking server in a safety area II. Compared with the prior art, the method for processing the relay protection definite value data solves the problem that time delay is caused due to manual copying and transfer of the relay protection definite value data, and timeliness of checking and updating of the relay protection definite value data is improved.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for processing relay protection fixed value data. Background technique [0002] The relay protection device is one of the most important secondary equipment in the power system. It is the guarantee for the safe operation of the power system and plays a key role in preventing the occurrence and expansion of accidents. Therefore, it is necessary to do a good job in the setting calculation of the power grid relay protection setting Work is an important condition to ensure the safe operation of the power grid. In order to meet the requirements of the four characteristics (reliability, selectivity, rapidity, and sensitivity) put forward by the power grid for relay protection, and to give full play to the effectiveness of relay protection, it is necessary to choose a reasonable value for relay protection. [0003] At present, the relay protection fixed value is...
