Embodiment Construction

[0044] The present invention will be further described below in conjunction with the drawings and embodiments.

[0045] Such as Figure 1-Figure 7 As shown, an active security defense method for wind farms based on automated decision-making includes the following steps:

[0046] Step 1: Use knowledge automation technology to establish a wind farm active safety defense decision demand table.

[0047] Decision Requirments Diagram (DRD) is a key technology in the field of knowledge automation. The diagram represents the structure of the decision process that needs to be made as a structure with business knowledge and data support domains, which is composed of decisions or sub-decisions The internet.

[0048] Such as figure 2 As shown, the specific steps are as follows:

[0049] 1-1) Determine the decision points, knowledge domains and data domains of wind farm active safety defense decision-making needs through the decision-making requirement analysis seminar (DRAW). This decision-makin...

Abstract

This invention discloses an active security defending method of a wind farm based on automated decision. The method comprises the steps of establishing a wind farm control instruction white list detection filter mechanism to acquire a theoretical white list filter detection result type; establishing a probability interval of a running situation evaluation of the wind farm; acquiring a security rule list; entering a detection mode of the white list detection filter mechanism to acquire an actual white list filter detection result; calculating a probability for sending various operating instruction behaviors by an operator under current running situation of the wind farm; and substituting the actual white list filter detection result and the probability interval into the security rule list to acquire a decision result. Through combing the situation awareness technology with the white list detection filter mechanism, suggestions are provided for the running security decision of the wind farm; the completeness of the information security defending method of the wind farm can be improved; the security concerns of wind farm owners for incorporating data into internet can be eliminated; and the development of wind power big data can be effectively promoted.

Description

Technical field [0001] The invention relates to the field of wind power, in particular to an active safety defense method for wind farms based on automated decision-making. Background technique [0002] With the development of smart grid technology and the continuous improvement of wind power operation and maintenance service levels, it has become a trend to transmit wind farm operation data to a remote monitoring center in real time via the Internet to achieve large-scale cluster monitoring and intelligent operation management with refined scheduling. However, power system accidents caused by malicious cyber attacks such as the "Stuxnet Incident" and "Ukraine Power Outage Incident" have also made wind farm owners deeply concerned about the safety of monitoring the intranet and Internet connection. Therefore, in view of its own characteristics in the power system field, it is particularly urgent to study the energy Internet information security protection technology under the bac...
