- the power can be leveled and the reflow furnaces R2 and R3 can be started.
- the mounting line power control apparatus 100 when the demand power of the first mounting line exceeds the target value in the first period, the target value of the demand power of the second mounting line is set.
- the power consumption of the mounting board production apparatus included in the second mounting line is reduced so as not to exceed the target value after the reduction.
- the power reduction devices are determined in order of the second priority, and the operation of the equipment included in the determined power reduction device is performed.
- the power consumption is reduced by stopping the operation. As a result, the power used can be reduced in order from the mounting board production apparatus with the lowest priority.
- the power consumption of the power reduction device is increased in the second period. Therefore, the operation of the power reduction device that was scheduled to be performed in the first period can be performed in the second period without exceeding the target value.
- the demand value target power of the second mounting line is reduced. If the first period is included in the discount time zone, the demand power of the second mounting line is reduced. Do not reduce the target value. That is, in the time zone other than the discount time zone, a large amount of power is used in the factory, so the target value of demand power for the second mounting line is reduced. Moreover, in the discount time zone in which the power used in the factory is reduced, the target value of demand power for the second mounting line is not reduced. Thereby, the use mode of electric power can be switched for every time slot
- the target value of demand power of the first mounting line when the target value of demand power of the first mounting line is reduced, the target value of demand power of the mounting line different from the first mounting line is increased.
- the mounting line power control apparatus 100 according to the present invention has been described using the above embodiment, but the present invention is not limited to this.
- the priority acquisition unit 120 acquires the first priority and the second priority, and the power usage change unit 140 determines the power reduction device from the first priority and the second priority. It was decided to reduce the power used by the power reduction device. However, the priority acquisition unit 120 does not have to acquire the second priority, and the power usage changing unit 140 determines the power reduction device only from the first priority and reduces the power usage of the power reduction device. May be.
- the target value changing unit 130 determines whether or not the first period is included in the discount time zone, and based on the determination result, the demand value in the first period of the second mounting line. The target value of power was reduced. However, the target value changing unit 130 may reduce the target value of demand power in the first period of the second mounting line regardless of whether or not the first period is included in the discount time zone.
- the target value changing unit 130 determines the demand power in the first period of the third mounting line when the target value of the demand power in the first period of the first mounting line is reduced. The target value was increased. However, the target value changing unit 130 does not increase the target value of demand power in the first period of the third mounting line even if the target value of demand power in the first period of the first mounting line is reduced. May be.
- the target value changing unit 130 determines whether or not the demand power exceeds the target value for each mounting line.
- the target value changing unit 130 may repeat the feedback of the measurement error of the power consumption of each device to correct the demand power so that the determination is accurately performed.
- the target value changing unit 130 sets the second amount of demand power for the second mounting line so that the amount of decrease decreases to the same value as the amount of increase in demand power for the first mounting line. We decided to reduce the target value of demand power on the mounting line.
- the amount of decrease in the target value of demand power in the second mounting line is not limited, and may be larger or smaller than the amount of increase in demand power in the first mounting line.
- the target value changing unit 130 causes the third mounting line so that the increase amount of the demand power target value becomes the same value as the decrease amount of the demand power of the first mounting line.
- the target value of demand power on the mounting line was increased.
- the increase amount of the target value of the demand power of the third mounting line is not limited, and may be larger or smaller than the decrease amount of the demand power of the first mounting line.
- the used power changing unit 140 changes the starting time of the reflow furnace 600 to reduce the used power so that the demand power does not exceed the target value.
- the used power changing unit 140 may change the starting time of the motor to reduce the used power so that the demand power does not exceed the target value. In this case, by shifting the start and stop of the motor between the mounting lines, the start power of the motor and the regenerative power by the motor can be offset, and the power used can be reduced.
- the present invention can be realized not only as such a mounting line power control apparatus 100 but also as a mounting line power control method having a characteristic process performed by a processing unit included in the mounting line power control apparatus 100 as a step. Can also be realized. Further, it can be realized as a program or an integrated circuit for causing a computer to execute characteristic processing included in the mounting line power control method. Needless to say, such a program can be distributed via a recording medium such as a CD-ROM and a transmission medium such as the Internet.
- the present invention may be adapted to increase / decrease in the target value of demand power of the entire mounting line when there is a change in the power consumption of other large load fluctuation facilities in the factory other than the mounting line.
- the present invention can be applied to a mounting line power control apparatus that controls power consumption of a plurality of mounting lines, and in particular, a mounting line power control apparatus that can efficiently suppress an increase in power usage in the plurality of mounting lines as a whole. Applicable to etc.
