Embodiment Construction

[0030] The present invention is described in detail below in conjunction with accompanying drawing and embodiment:

[0031] Such as figure 1 Shown, the storage and transmission method of broadband measurement data, its steps are: comprise

[0032] Step 1 Obtain the required broadband measurement data from the substation, and quickly cache, process, extract, and store the broadband measurement data in computer 1;

[0033] Step 2: Processing the extracted broadband measurement data, that is, encrypting the stored broadband measurement data;

[0034] Encryption of broadband measurement data includes:

[0035] After the broadband data is stored, the data will pass through the encryption module, which includes a data formatting and framing module, a data security module, a data security monitoring module, and a data docking transmission module. When the broadband data passes through the data formatting and framing module , the format of the data frame is uniformly divided into f...

Abstract

The invention discloses a method for storing and transmitting broadband measurement data, which comprises the following steps of: quickly caching the broadband measurement data, establishing an association relationship among various types of data, encrypting the stored data, and finally transmitting the broadband data to a master station. In order to facilitate storage and transmission of unified broadband measurement data, in the storage process, framing all data according to a unified file format in the broadband measurement method, after security encryption, transmitting the framed data to a PMU concentrator according to a unified transmission protocol, and uniformly transmitting the data to a master station by the concentrator.

Description

technical field [0001] The invention belongs to the field of electric power automation, in particular to a method for storing and transmitting broadband measurement data. Background technique [0002] As the penetration rate of power electronic methods in power systems is getting higher and higher, and the broadband characteristics of electrical quantities are becoming more and more significant, new requirements are put forward for the monitoring frequency band range and response speed of power system signals. A fast broadband measurement method has been proposed to realize The fast storage and high-precision transmission of broadband data can greatly improve the storage and extraction of data, and finally transmit the broadband data efficiently. [0003] The data obtained by the current broadband measurement method is becoming more and more difficult. It is impossible to store and extract the broadband data while measuring the data, and it is impossible to ensure the safe t...
