电流检测
请教高手:为什么在电流检测3-2 变换用电压测量模块输出作为三相电压作为 3-2 输入电压出错? 计算机给出下面信息提示:<BR>Error evaluating 'InitFcn' callback of Voltage Measurement block (mask) 'V3'. Error using ==> e:/matlab6p5/toolbox/powersys/powersys/private/psbsort (psberror)<BR>Connection error!<BR> 出现这样一来问题该怎么处理?<BR> 谢谢了!<BR>回复：（电力仿真）电流检测

<P>非常感谢给我解了围.</P>求助
用simulink建模用到了电压测量模块，但在运行时出现了这样的错误Error evaluating 'InitFcn' callback of Voltage Measurement block (mask) 'Voltage Measurement'. Error using ==> svd
NaN or Inf prevents convergence
有谁见过这样的错误？知道什么原因或是怎样解决？
有人说是使用环境错误，但还是不太明白
