Abstract

PURPOSE: To eliminate the influence of disturbance such as noise, chattering, etc., by measuring an interval time of a measuring pulse, and excluding a pulse with a time interval being shorter than a prescribed tie, from counting.
CONSTITUTION: Each pulse interval time of a measuring pulse from a pulse detector or a watthour meter, namely, time t1Wtn required from a rise of the pulse to a rise of the next pulse is measured. Each time of this time t1Wtn is compared with a reference time, and in case it is longer than the reference time, it is counted as a normal pulse, and in case it is shorter than the reference time, it is handled as a continuous pulse as a pulse 3', and counted s one pulse as a whole. Next, a numerical operation is executed from an elapsed time and a counting value, a result of the operation and a target value of the demand power are compared, and the demand power is monitored and controlled so that the demand power is included in the targeted value.
