| Abstract: | According to the extreme value principle,the minimum condition of theerror in an automatic low frequency decreasing loads equipment will be derived in this paper.Then through solving simuItaneous equations which contain total decreasing loads power inthe equipment and individual grades turn off powers,an optimum recovering frequencycould be evaluated,and then optimum individual grades turn off powers.On this condition,the result will be optimum, or the selectivity of the equipment should be optimum. |
