Including A phase changed power parameter "+20W ", B phase changed power parameter "+10W " and C phase changed power parameter " -15W ", first
Changed power direction is matched, obtaining single-phase power running parameter is "+22W " and A phase changed power parameter "+20W " and B
Phase changed power parameter "+10W " matches, and further threshold decision is carried out to changed power numerical value, if changed power threshold value is
" 5W ", then numerical difference of the single-phase power running parameter between "+22W " and A phase changed power parameter "+20W " is " 2W ", single-phase
Numerical difference of the changed power parameter between "+22W " and B phase changed power parameter "+10W " is " 12W ", and " 12W " is greater than " 2W ",
