对于差动继电器方程,该错误“在程序中无法从sym转换为逻辑”是我的问题。 谢谢
syms IS1 K1 IS2 K2 Idiff Ibias ;
Ibias=1.5 ;
Idiff=3 ;
if Ibias < IS2
Idiff > (K1*Ibias+IS1) %then trip
elseif Ibias >= IS2
Idiff >= (K2*Ibias)-(K2-K1)*IS2 +IS1 %then trip
end
%IS1: The basic differential current setting
%K1: The lower percentage bias setting
%IS2: The bias current threshold setting
%K2: The higher percentage bias setting
