業務用電力の消費量ＷＨｒが計測される。By the way, in the case of a consumer equipped with two types of equipment like this, as shown in Figure 2, the distribution line (1) from the substation etc.
A transformer (2) is connected to the transformer (2), and a first power demand facility (3) consisting of a plurality of commercial loads and a second power demand facility consisting of a plurality of industrial loads are connected to the transformer (2). (41 is connected to the transformer (21's primary distribution line (1)
) is installed on the integrated power meter 15) to measure the total power received (total power purchased amount) WHs, and the integrated power meter 15) installed in the first power demand facility (other integrated power installed in the branch road on the 31 side The meter (6) measures the consumption amount WHr of commercial power in the first power demand facility (3).

。However, since the unit price of commercial electricity is higher than that of industrial electricity, for example, the consumer shown in Figure 2 is equipped with private power generation means to receive commercial electricity with a high unit price. Although it is desired to reduce the amount of electricity purchased by the first power demand facility (3), no suitable method has been considered so far.
そこで、本発明では、自家発電手段による自家にするこ
とを目的としている。Therefore, the present invention aims to create a private power generation system using private power generation means.
つぎに、上記目的を達成するための手段を、実施例に対

的手段を講じている。That is, in the present invention, there are two types of equipment (1), a first power demand facility (31) that receives commercial power with a high power unit price, and a second power demand facility (4), that receives power for industrial use with a low power unit price. 3) A synchronous generator (7) as a private power generation means is installed in a consumer equipped with (3) and (4), and the power consumption of the first power demand equipment (3) and the equipment (3) are measured. The output end of the generator (7) is connected to the distribution line between the electricity meter (6) and the power generated by the generator (7) is preferentially supplied to the first power demand facility +31. We are taking technical measures to do so.

) and the power meter (6).
By connecting the output end of the power generator (7), the power generated by the generator (7) is not integrated by the integrating power meter (6), and the first power source receives commercial power with a high unit price. The demand facility (3) is preferentially supplied, and the amount of electricity purchased by the first power demand facility (3) 9 is reduced.
つぎに、本発明を、その１実施例を示した第１図ととも
