Embodiment Construction

[0059] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0060] A distribution network operation evaluation method based on data interception and spark, such as figure 1 shown, including the following steps:

[0061] Step 1, capture the terminal communication message, and obtain the mirror message through the mirror port of the switch;

[0062] In this embodiment, the specific method of step 1 is: obtain the message from the collection terminal, and forward the mirrored message to the message processing server by setting a mirror port for the collection switch.

[0063] Step 2, analyze the mirror message of step 1, filter the message of 101,104 agreement, and store the message to HDFS;

[0064] like figure 2 As shown, the specific steps of said step 2 include:

[0065] (1) Obtain the message, and implement circular capture to the message in the image based on the libpcap packet capture library, thereb...

Abstract

The invention relates to a distribution network operation evaluation method and system based on data interception and spark, and that the method comprises the following steps: 1, capturing a terminalcommunication message, and obtaining a mirror image message through a mirror image port of a switch; Step 2, analyzing the mirror image message in the step 1, filtering the message with the protocol of 101 and 104, and storing the message in an HDFS; Step 3, obtaining a message from the HDFS, analyzing the message on a spark platform, obtaining parameters in the message, analyzing and processing the parameters, and calculating a quantitative evaluation result of a key operation index for evaluating the operation condition of the distribution network according to the parameters so as to evaluate the operation condition of the distribution network; And step 4, displaying the obtained evaluation result through a web page. The key evaluation index of distribution network operation can be calculated in real time, the distribution network operation state is evaluated, and the automation level of the distribution network is improved.

Description

technical field [0001] The invention belongs to the technical field of power system automation, and relates to a distribution network key operation index evaluation method and system, in particular to a distribution network operation evaluation method and system based on data interception and spark. Background technique [0002] At present, the existing technology to obtain distribution network data cannot guarantee the real-time and authenticity of the data. At the same time, there is a performance bottleneck when processing massive data, and it is impossible to calculate the key indicators of the distribution network operation in real time. evaluation indicators. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and propose a distribution network operation evaluation method and system based on data interception and spark with reasonable design, low cost, high reliability and strong real-time performa...
