Abstract
Provided is a household electricity storage-and-use system with timing control. A timer controls three power supply lines in a time-sharing mode. Direct current electricity generated by a solar power generation assembly is divided into two branches which are connected with the timer in a point mode. One branch of the electricity is converted through a photovoltaic inverter into alternating current electricity which can be directly used by household appliance units, namely the branch of the electricity is converted into electric energy which is of the same specification with mains supply units. The other branch of the electricity is directly connected with the timer, and then is connected with a storage battery through a control box. A third power supply line is directly and electrically connected with the timer, and is used for directly providing electricity for the household appliance units or charging the storage battery. The timer is connected with the control box. The control box is connected with household appliances. A principle that mains supply is used in a matched mode on the basis of using a solar cleaning energy source, and electricity of the mains supply when in a low ebb of electricity use is preferentially used is adopted, and finally the function is achieved through the timer, the control box and the storage battery, and energy sources and electricity expense are saved to the maximum.
Description
Technical field
The present invention relates to a kind of time-controlled family storage using electricity system, be mainly used in the household electricity system, the domestic consumer of new energy and mains supply is installed especially simultaneously.
Background technology
Along with the situation of energy scarcity is more and more serious, some regional supply of electric power at present is difficult to be guaranteed, this kind situation during the broiling summer and the zone that affects cold winter larger, the phenomenon of power cuts to limit consumption often appears in some large size cities at this moment.Meanwhile, the technology of solar power generation assembly generating is quite ripe, and during some domestic consumer, solar energy and electrical network are powered simultaneously.
Accordingly, present some areas and begin to take the market-oriented control measures of tou power price to guide people's electrical energy saving, for example, the electricity consumption time of one day is divided into three sections, electricity price is floated in day part, 7 o'clock to 11 o'clock every day and 17 o'clock to 21 o'clock are " during the peak ", and 11 o'clock to 17 o'clock is " at ordinary times ", and its time is " during paddy ".The purpose of doing like this is to encourage people at " during paddy " multiplex electricity.But due to the custom of people's consumption habit and habits and customs, this kind mode role is less, has increased on the contrary the electric cost of a lot of families.
Summary of the invention
problem for the prior art existence, the invention provides a kind of time-controlled family storage using electricity system, mainly to use at emphasis on the basis of solar energy clean energy resource, be used in conjunction with mains supply and also more preferably use the electrical network low power consumption time electric weight be principle, finally pass through timer, control cabinet and storage battery are completed this function, realize the timing controlled of family's storage electricity consumption, the intelligent degree of the present invention is high, stable, can save to greatest extent electric cost for the user, realized simultaneously taking full advantage of of solar energy, energy savings, environmental benefit is obvious, it can the intelligent timesharing of completing household electricity store up electricity consumption, prepreerence use solar energy, electric energy when secondly preferentially using the mains supply low ebb, can save to greatest extent the energy and electric cost.
to achieve these goals, the technical solution used in the present invention is: a kind of time-controlled family storage using electricity system, comprise mains supply unit and Household Appliance unit, native system also comprises the solar power generation assembly, photovoltaic DC-to-AC converter, timer, watch-dog, control cabinet, storage battery, inverter, wherein, three tunnel supply lines are controlled in the timer timesharing: the direct current that the solar power generation assembly sends is divided into two-way and is connected with timer point, the photovoltaic DC-to-AC converter of leading up to be converted into can be directly for the alternating current of household electrical appliance unit, namely be converted into the electric energy with mains supply unit same size, another road directly is electrically connected to timer, is connected with storage battery by control cabinet again, Third Road supply line directly is electrically connected to timer, and it is directly for the power supply of household electrical appliance unit or be charge in batteries, and timer is connected with control cabinet, and control cabinet is connected with household electrical appliance.
