摘　　要：传统的全厂单元机组周界监控方法无法全面分析监控各次谐波阻抗参数,导致监控结果有较大波动,扰动抑制能力也偏弱,为此设计了一种基于MIS模型的全厂单元机组周界监控系统。构建约束参数模型,利用MIS模型参数融合方法结合无源滤波器检测方法,实现联合特征分布集融合滤波检测处理。采用二次调频参数控制方法,分析各次谐波阻抗参数。引入MIS模型,识别全厂单元机组周界的参数,利用谐波电流参数分布结果完成全厂单元机组周界监控系统设计。仿真结果表明,采用该方法设计的监控系统输出稳定性较好,扰动抑制能力较强,提高了全厂单元机组周界监控的智能化水平。The traditional whole-plant unit perimeter monitoring method can not comprehensively analyze the monitoring harmonic impedance parameters,lead to large fluctuations in monitoring results and weak disturbance suppression ability.Therefore,a perimeter monitoring system based on MIS model for whole plant units is designed.The constrained parameter model is constructed,and the MIS model parameter fusion method combined with the passive filter detection method is used to realize the joint feature distribution set fusion filter detection processing.The harmonic impedance parameters are analyzed by using the control method of secondary frequency modulation parameters.The MIS model is introduced to identify the parameters of the whole plant unit perimeter,and the monitoring design of the whole plant unit perimeter is completed by using the distribution results of harmonic current parameters.The simulation results show that the output stability of the monitoring system designed by this method is good,the disturbance suppression ability is strong,and the intelligence level of the whole plant unit perimeter monitoring is improved.
