Abstract

PURPOSE: To enable the forecast even with longer sampling time, by counting the number of pulses inputted from the watt with transmitter and operating the forecast value, from the time backed by sampling time to the time every unit time.
CONSTITUTION: The power energy used for the load 3 is measured with the watt meter with transmitter 2, the pulse proportional to the value is inputted to the counter 4 of the demand control unit 1 to output the present value W1 and it is displayed at the present value display unit 5. Further, the sampling value counter 17 stores the count value every one minute for five minutes and the average value to output it every one minute after converting it into electric energy. This output and the remaining time are operated at the multiplication circuit 26 and the forecast value WX is calculated with the addition of the present value W1 at the addition circuit 27. The difference between the forecast value WX and the objective Wb is calculated at the subtraction circuit 30, and the difference between the set value for interruption and application is calculated at the comparison circuit 35 to input it to the load control circuit 36.
