应用介绍

这是用matlab和PWRWRLD分别进行了暂态仿真，有阻尼仿真

XL_km=0.367; % ohm/km at 60 Hz
RL_km= 0.1*XL_km; % Resistance in ohm/km

KV_LL= 345; MVA_Base=100; % common 3-phase base
Z_Base=KV_LL^2/MVA_Base; % common base

% YBUS Creation
Z13_ohm=(RL_km+j*XL_km)*200; B13_Micro_Mho=4.5*200; % Line 1-3 is 200 km long
Z12_ohm=(RL_km+j*XL_km)*150; B12_Micro_Mho=4.5*150; % Line 1-2 is 150 km long
Z23_ohm=(RL_km+j*XL_km)*150; B23_Micro_Mho=4.5*150; % Line 2-3 is 150 km long
Z13=Z13_ohm/Z_Base; Z12=Z12_ohm/Z_Base; Z23=Z23_ohm/Z_Base; % line impedances in per unit

Y(1,1)=1/Z12 + 1/Z13; Y(1,2)=-1/Z12; Y(1,3)=-1/Z13;
Y(2,1)=-1/Z12; Y(2,2)=1/Z12 + 1/Z23; Y(2,3)=-1/Z23;
Y(3,1)=-1/Z13; Y(3,2)=-1/Z23; Y(3,3)=1/Z13 + 1/Z23;
G(1,1)=real(Y(1,1)); B(1,1)=imag(Y(1,1)); G(1,2)=real(Y(1,2)); B(1,2)=imag(Y(1,2)); G(1,3)=real(Y(1,3)); B(1,3)=imag(Y(1,3));
