Abstract

PROBLEM TO BE SOLVED: To reduce interruption due to excess of the capacity of a distribution breaker by deciding whether new electric equipment can be added to distribution lines, and controlling the breaker based on the result of the decision. SOLUTION: A distribution controller means 9a is fed with a contract power demand from a contract power demand input means 4, and then with power consumption of the entire system from a wattmeter 5a. The entered power consumption of the entire system is compared with the contract power demand to decide to what extent leeway is allowed. Further, whether electric equipment 1d can be added is decided by an addition deciding means 8. When addition is decided as being possible, the electric equipment 1d is enabled. When addition is decided as being impossible, the electric equipment 1d is not supplied with power and is disabled, and control is exercised to change the combination of distribution breakers 3.

[0003] In addition, electric equipment has various unique functions, and when the power supply system is shut down, including a momentary power failure, the customized state of the functions may be reset and reset. In such a case, a setting manual is required, and the setting before shutting down is left only to a personal storage medium, which takes time.

Further, the electric equipment used is increasing year by year, and the electric power used is steadily increasing year by year, and there is a problem that it is necessary to save power. There is a demand for minimizing standby power and minimizing power during operation of electrical equipment.

[0012] In addition, there is a problem that running, stopping, and further changing the setting of electric equipment are accompanied not only by improvement of comfort but also by lack of additional functions such as remote operation and collective operation with the improvement of living standards. There is a demand for improved operability using a communication medium or the like.

FIG. 2 shows a control flowchart of the power distribution control means 9a.

As shown in FIG.
As for a, the contract power, that is, the maximum allowable consumption is input by the contract power input means 4. Next, the power consumption of the entire system is input by the wattmeter 5a. Further, it is determined how much the input power consumption of the entire system has a margin as compared with the contract power. Furthermore, the power consumption of the distribution line to which the electric device 1d is to be added is detected from the wattmeter 5e. The amount of power that can be added is calculated from the power consumption of the distribution line and the suppliable power of the distribution line. Further, the addition determining means 8 determines whether the addition of the electric device 1d is possible. If the addition is possible, the electric device 1d can be used. However, if the addition is not possible, the added electric device 1d is not supplied with power and becomes unusable.

Next, the contract power input means 4 will be described with reference to FIG.

As shown in the figure, the contract power input means 4

And a dip switch recognizing means 4c. The dip switch recognizing means 4c reads and recognizes a manually set pattern of the dip switches 4a and 4b.

Next, the additional judging means 8 will be described with reference to FIGS.

The available maximum power is compared with the power consumption of the entire system before the addition, and the supply power that can be added, that is, a margin is calculated. Next, the supply power before addition of the distribution line to be added is compared with the suppliable power of the distribution line to be added to calculate the supply power that can be added to the distribution line. The calculated possible additional power of the entire system, the possible additional power of the distribution line, and the power consumption of any of the additional electrical devices 1a to 1d are compared to determine whether the addition is possible.

If it is not possible to add any of the electric devices 1a to 1d only by changing the setting of any of the electric devices 1a to 1d having a low priority, the setting state of any of the electric devices 1a to 1d having a low priority is changed. The setting is stored in the setting storage means 12, and the power is cut off. Any of the power distribution switches 3a to 3j that are in an unused state due to the power interruption is connected to any of the additional electric devices 1a to 1d. Further, at the time of power recovery, the setting transmitting means 13 transmits the setting state of any of the electric devices 1a to 1d whose power has been cut off, and the setting state also returns.
