摘　　要：伴随信息化程度不断提高,隐蔽攻击将对风机变桨距控制系统构成威胁。为此,设计了一种防御结构。将攻击信号对被控对象的影响反馈给控制器,由控制器实时调节控制输出信号,进而防御隐蔽攻击。分别在有攻击和无攻击场景下分析了采用防御结构后系统的稳定性。仿真结果显示,在隐蔽攻击时间段内,采用防御结构后,风机输出功率与设定值的平均误差为0.004 MW;在无攻击时间段内,风机输出功率与原系统保持一致。该结果说明,防御结构有效。With the development of informatization degree,covert attack will be a threat to the variable pitch control system of wind turbines.To this end,this paper designs a defensive structure.The impact of attack signals on the controlled object is fed back to the controller,which adjusts the control output signal in real time to prevent the covert attack.The stability of the system after adopting the defense structure is analysed in both attack and no-attack scenarios.The simulation results show that after adopting the defense structure,the average error between the wind turbine output power and the set value is 0.004 MW in the period of covert attack,and the wind turbine output power is consistent with the original system in the period of no attack.The results show that the defense structure is effective.
