The direct current voltage of the direct current electric equipment is two groups of standard direct current voltages which are unified with the output voltage of the direct current wiring board, one group of standard direct current voltages is 110V high direct current voltage, the other group of standard direct current voltages is 48V low direct current voltage, the special distribution line adopts a three-wire distribution system, and the three wires refer to a common direct current zero line, a high voltage direct current positive line and a low voltage direct current positive line.

For some special kinds of electric appliance systems, only AC electric appliances can be purchased due to less market demand, and the problem is solved by indirectly adopting an intermediate conversion electric appliance with DC to AC of 220V.

The cost of general electric appliances of the whole set of direct current electric system for the buildings can be reduced by half, and the power consumption can be reduced by half. That is, an electrical device within a building system that uses 400kw of ac power is only 200 kw of ac power relative to a dc power supply.

If the direct-current green energy of the whole building is adopted for power supply, the investment of green energy conversion equipment is directly reduced by half, and the complete power supply can be realized by basically 250 kilowatt full-power green energy equipment by considering 80% of load rate; if an alternating current mode is adopted, the direct current green energy is converted into the alternating current mode, 20% of converted direct current to alternating current link loss and 80% of load rate are considered, and 560 kilowatt full-power green equipment investment is basically needed to realize complete power supply.

More importantly, the power consumption of the building system is that the power plant transmits to the building distribution transformer through a high-voltage line, generally 5 alternating current transformers and line losses are needed, the lowest loss of the transmission line and the transformer is calculated for 10% of each transformer, at least 50% of building load power is lost, a 400 kilowatt building alternating current power consumption system needs a 500 kilowatt distribution transformer, and the power generation power occupied by the power plant is at least: 400KW +500KW × 10% × 5 =650KW, and the electric energy required by the power plant is 812.5KW when the power plant calculates with 80% of load.

If a direct current power utilization system connected with a mains supply power grid is adopted, a high-voltage automatic switch is connected in series at the rear side of a high-voltage manual switch of a building distribution transformer, the high-voltage automatic switch is controlled by remote dispatching, and the high-voltage automatic switch is directly and automatically cut off in a power utilization peak device of the power grid, all electric energy adopts a mode of real-time wind-solar complementary green electric energy, green electric storage of a second storage battery and load power following direct current diesel generator emergency power supplement, wherein the real-time wind-solar complementary green electric energy is generated by a solar battery module and a roof full-environment applicable fan system, the green electric storage of the second storage battery is stored by an electric storage module, and the direct current diesel generator emergency power supplement is generated for a diesel generator.

In the power utilization peak machine of the power grid, commercial power rectification is adopted to charge the second power storage system, and the first time of the charging time of the energy storage peak regulation storage battery pack is the electric energy of green energy in the low-peak power utilization period at night, namely the electric energy converted from wind energy; the second time is the external power failure condition, the main inverter and the standby inverter cannot be connected to the grid for power transmission, and all green electric energy is used for charging the storage battery; the third time is that the voltage of an external power grid is low, green conversion energy is redundant under the condition that only a main inverter is allowed to work alone, the voltage of a storage battery assembly of the direct-current electric equipment after direct-current voltage stabilization is increased to a safety protection threshold value, and an energy storage peak-shaving storage battery is automatically started to charge; and the fourth time is the need of considering the peak regulation of the power grid in the daytime, when the green energy generated at other times is predicted not to be enough to fill the energy storage peak regulation storage battery pack, the central machine room plans and arranges, and the rectifier is used for rectifying the low-peak power of the commercial power in the daytime to fill the storage battery so as to be converted and transmitted to the power grid by the inverter when the power consumption in the daytime is high.

The time of energy storage peak regulation and discharge is converted electric energy in the peak period of electricity utilization in daytime, and the specific time can be finished according to the combined scheduling of a remote central machine room so as to meet the peak supplementing requirement in the required time period.

When the voltage of the power grid is low, the voltage is output by a main inverter of a voltage stabilization output type, the voltage of the power grid is normal, the voltage is output by a standby inverter of a common type, and when the converted green energy is sufficient, the main inverter and the standby inverter can simultaneously carry out peak regulation output.

Considering the probability that the electricity consumption of the building system direct current electrical equipment has electricity consumption time, the lowest layout scheme of the green energy of the roof green wind-solar complementary peak shaving power station of the 200 kilowatt building direct current electrical equipment system is as follows: 100 kilowatt photovoltaic, 100 kilowatt roof wind power, 500 ampere-hour energy storage lithium battery system and 50 kilowatt load power follow a direct-current diesel generator.

For the cost of generating electricity by adopting a diesel generator, the general electricity consumption cost is 1.6 yuan per degree, but in a roof peak shaving system, if diesel is completely adopted for generating electricity in the peak period of a power grid, 1 hour of electricity consumption of a 250 kilowatt direct current electric appliance needs to consume diesel oil cost: 250 × 1.6=400 yuan.

After diesel oil is used for generating electricity, the high-voltage automatic switch is switched off, and compared with the electric energy of 650 degrees of a saved power plant, the high-voltage automatic switch can provide 400 degrees of electric energy for users at other places of a power grid, and the total benefit of diesel oil generation is as follows: other users 400+ building direct current users 250 degrees =650 degrees of electricity, which is equivalent to the comprehensive electricity consumption cost of diesel oil: 0.6 yuan/degree.

The scheme of the dc power system connected to the utility grid proposed in this embodiment can be generalized to 10 ten thousand 200 kw dc power stations, and the maximum peak shaving power created by the system is: 650kw × 10 ten thousand =6500 ten thousand kw, creating a tremendous value.
