This team Yu2021Annual for the high -voltage DC system inIEEE Transactions on Power SystemsJournal (SCIOne District) Published a paperFrequency inject Based HVDC Atfense Control Via Squeeze-Excity Double CNN(High -voltage DC compression incentive dual based on frequency -based injectioncnnoffensive and defensive control).

High -pressure DC(HVDC)The system has independent controllability and fast power adjustment capabilities，It can provide a variety of auxiliary services except for conventional large -capacity transmission，is a promising technology。But，WithPMUDatafdias (FALSE DATA Inject Attack)Increase of attack，Once the data collected by the high -voltage DC system is attacked，The high -voltage DC system may cause an error response，threatening the operation of the system。How to ensure aPMUThe security of the high -voltage DC auxiliary business m88 sports bettingm88 live casino gamescontrol of the high -voltage DC auxiliary business has become a problem that is urgent to solve。To reduce risk，This paper proposes a based onfdiasThe high -voltage DC attack defense control of the detection method。First，Proposed dual -convolutional neural networks based on squeezing incentives(SE-DCNN)，Fast recognition of attack frequency type based on time domain and frequency domain signals; fdiasThe duration of the local group is detected. Then, useSE-DCNNResults，Reorganized high -voltage DC auxiliary service control framework，Proposed a high -voltage DC attack defense M88 games apkcontrol，to inhibit various types offdiasThe potential effect on the auxiliary service of the high -voltage DC system。Different experimental results indicate，The proposed method can be significantly reducedfdiafrequency deviation and oscillation.
