摘　　要：配电系统负反馈放大电路的电流中存在大量尖峰噪声,造成电流瞬间增大,导致配电系统中的电气设备受到损毁而无法正常运行。利用传统算法进行负反馈放电电路电流中尖峰噪声过滤,无法避免由于配电系统对于电流较强的随机性导致尖峰噪声难以过滤的缺陷,从而降低了负反馈放电电路电流中尖峰噪声过滤的准确性。为此,提出一种基于校验滤波算法的负反馈放电电路电流中尖峰噪声过滤方法。详细阐述了根据检验滤波算法进行负反馈放电电路电流中尖峰噪声过滤原理,并将该原理应用到配电系统中电气设备的运行过程中。实验表明,该方法提高了负反馈放大电路电流中尖峰噪声过滤的准确性,保证了配电系统的正常运行。The power distribution system existing in the current negative feedback amplifier circuit peaknoise in great quantities, cause the current moment, causes the damage to electrical equipment in thepower distribution system to normal operation. In the use of traditional algorithm for negative feedbackdischarge circuit current peak noise filtering, is inevitable because of the power distribution system forcurrent need strong randomness defects lead to rush to filter noise, which reduces the negative feedbackin discharge circuit current peak noise filtering accuracy. For this, put forward a calibration filteralgorithm based on the feedback of discharging circuit current peak noise filtering method. According totest of filtering algorithm is presented in detail in negative feedback discharging circuit current peaknoise filtering theory, and apply this principle to the operation of electrical equipment in distributionsystems, and improve the negative feedback amplifier circuit in the current peak noise filtering accuracy,and ensure the normal operation of the power distribution system.
