WebMahmoud Fawzi Dear sir Matlab do not have its inbuilt block to extract the sequence voltages from individual phases. Hence I feel the extraction of individual phase voltages must be done 1st, then the conventional formula must be applied by incorporating the 'alpha' operator and associated formulas. va+(t)= 1/3[va(t)+alpha*vb(t)+alpha^2*vc(t)] etc. Web追问. 应该是 ：. Warning: You have required continuous-time simulation of a system containing switches or. nonlinear elements. Warning: Output port 1 of 'untitled/Three-Phase V-I Measurement1' is not connected. 追答. 第一个警告意思是需要连续仿真，可能你的powergui里面选的是离散仿真吧，改成连续的看可 ...
