Abstract:

从波动量法的基本理论入手,研究波动量比值符号的概率统计特征,通过理论分析提出当谐波源受到多种随机因素影响时波动量比值的实部和虚部的概率密度服从广义柯西分布,并选取PearsonVII公式对此进行描述。然后,给出利用概率统计和非线性曲线拟合估计谐波阻抗的具体方法及步骤。进而分析影响波动量法误差的各种因素,推导理论误差表达式并提出修正误差的措施。与各类依赖判据进行数据过滤的方法相比,概率法的数据处理过程更为简便,具有较好的通用性、可靠性及抗干扰性,同时,概率法能更全面地分析波动量比值的概率统计特征,避免数据的误处理。蒙特卡洛仿真及实例应用分析验证了所提方法的有效性和实用性。
