电力系统拓扑分析、孤岛数,关联矩阵法
说明: 电力系统拓扑分析、孤岛数,关联矩阵法把主接线的节点和母线的每一进出线连接点作为拓扑图的节 点,把开关元件作为拓扑图的支路,建立节点.支路关联矩阵表示电网的基本拓 扑结构。然后定义矩阵“与.或’’乘法运算,利用连通性的传递性质实现对电力 网络结构的辨识。(In the incidence matrix method, the node of the main connection and the connection point of each incoming and outgoing line of the bus are taken as the node of the topology diagram, and the switching element is taken as the branch of the topology diagram to establish the node.The branch correlation matrix represents the basic topology structure of the power grid)

最大似然
说明: 两种不同的假设:
H1 : 0 xn A fn wn ( ) cos(2 ) ( ) = ++ π θ n=1,2,…,N,f0 为规一化频率
H0 : xn wn () () = n=1,2,…,N
其中 w[n]是均值为 0,方差为 2 σ n 的高斯白噪声,A 已知,样本间相互
独立,信号与噪声相互独立; 相位θ 是随机变量,它服从均匀分布
1 0 2 ( ) 20 p
θ π θ π ?? ≤ ≤ = ??? 其它
1)改变输入信噪比(改变 A 或噪声方差均可),给定虚警概率,画出
输入信噪比与检测概率之间的理论曲线。(注意:理论检测曲线与样本
数有关) 2)改变样本数,用 Monte-Carlo 实验方法得出 PF=0.001 时输入信噪比
与检测概率之间关系曲线(至少三条),并得出结论。 3)改变 M-C 实验次数,样本数不变,用 Monte-Carlo 实验方法得出 PF =0.001 时输入信噪比与检测概率之间关系曲线(至少三条),并得出
结论(Draw the theoretical curve between input SNR and detection probability)
