1. real-time unfixed point interpolation computing method is switched in a kind of step-length, it is characterised in that methods described comprises the steps:

  • A, first step-length point-like state value of electro-magnetic transient is calculated, find there is switch motion in step-length;

    B, interpolated value calculating is carried out to switch motion point state value;

    C, next step-length point-like state value is calculated from the switch motion point;

    D, from current step point extrapolated value to it is next calculating synchronizing point long;

    In the step B, the state value x based on previous step1With current step point-like state value x2, during to the switch motion point k1The state value x at quarterk1Carry out interpolated value calculating, the xk1Represented with following 1. formulas:
