In below describing, in order to illustrate instead of in order to limit, propose the detail of such as particular system structure, interface, technology and so on, thoroughly to understand the present invention.But, it will be clear to one skilled in the art that and also can realize the present invention in other embodiment not having these details.In other situation, omit the detailed description to well-known device, circuit and method, in order to avoid unnecessary details hinders description of the invention.

Embodiment one

Embodiments of the invention provide a kind of electric control system, as shown in Figure 1, DC suppling equipment 02, AC power supply device 03 and battery supply set 04 that this electric control system comprises control appliance 01, is connected respectively with described control appliance 01, wherein, described battery supply set 04 is connected with described DC suppling equipment 02 or described AC power supply device 03.

Concrete, in an embodiment of the present invention, control appliance 01 obtains the power output of DC suppling equipment 02, the power output of AC power supply device 03, the power output of battery supply set 04 and the operating power of power consumption equipment respectively, here, control appliance 01 can obtain the operating power of power consumption equipment by the rated current and rated voltage detecting power consumption equipment, certainly, also can be inputted the operating power of power consumption equipment to control appliance 01 by the terminal equipment being articulated in control appliance 01 outside.

Further, control appliance 01 can, according to preset strategy, select a power supply unit to be that power consumption equipment is powered as the first power supply unit from DC suppling equipment 02, AC power supply device 03 and battery supply set 04.Wherein, this preset strategy can have multiple, following the present invention only exemplary list three kinds, should be understood that, the preset strategy similar with the present invention also should belong to protection scope of the present invention.

Such as, this preset strategy is determine the first power supply unit according to the power output of DC suppling equipment 02.Concrete, because DC suppling equipment 02 is (such as solar powered etc.) that use clean energy resource to generate electricity mostly, therefore, can power to power consumption equipment by prioritizing selection DC suppling equipment 02, now, if the power output of DC suppling equipment 02 is greater than threshold value, DC suppling equipment 02 is that power consumption equipment is powered as the first power supply unit by control appliance 01; If the power output of DC suppling equipment 02 is less than threshold value, AC power supply device 03 or battery supply set 04 are that power consumption equipment is powered as the first power supply unit by control appliance 01, in addition, when the power output of DC suppling equipment 02 is less than threshold value, and the power output of AC power supply device 03 is 0, that is, current electric control system breaks down, now, control appliance 01 is in order to emergent, can determine that battery supply set 04 is the first power supply unit, carry out powering to guarantee power consumption equipment not power down directly to power consumption equipment.

Again such as, as shown in Figure 2, this electric control system also comprises the terminal equipment 05 (such as mobile phone, computer etc.) using external communication interface to be connected with control appliance 01, control appliance 01 can the mark of the first power supply unit that sends of receiving terminal apparatus 05, and the mark of this first power supply unit can comprise at least one in the type of this first power supply unit and model.Wherein, the type of this first power supply unit can be DC suppling equipment 02, AC power supply device 03 or battery supply set 04, and the model of this first power supply unit can be the concrete model of this first power supply unit.Like this, control appliance 01 just can, according to the mark of the first power supply unit, select a power supply unit to be that power consumption equipment is powered as the first power supply unit from DC suppling equipment 02, AC power supply device 03 and battery supply set 04.

Exemplary, terminal equipment 05 directly can send the model A110 of the first power supply unit to control appliance 01, determines the first power supply unit that model is A110 to make control appliance 01 according to this model A110 from DC suppling equipment 02, AC power supply device 03 and battery supply set 04.

It should be noted that, control appliance 01 is according to preset strategy, from DC suppling equipment 02, select a power supply unit a variety of in addition as the method for the first power supply unit in AC power supply device 03 and battery supply set 04, the present invention is not restricted this, such as, first power supply unit can be that control appliance 01 is from DC suppling equipment 02, Stochastic choice in AC power supply device 03 and battery supply set 04, again such as, if DC suppling equipment 02 is solar power supply unit, so, control appliance 01 just can determine the first power supply unit according to the power output of solar power supply unit, such as, when sunlight ray reaches certain index, because the solar panels in solar power supply unit can convert solar energy into the electric energy of certain power, if now the power output of solar power supply unit is greater than the operating power of power consumption equipment, control appliance 01 determines that solar power supply unit is the first power supply unit, if when the power output of solar power supply unit is less than the operating power of power consumption equipment, control appliance 01 can determine that AC power supply device 03 is the first power supply unit.

Further, the first power supply unit is determined at control appliance 01, and use the first power supply unit for after power consumption equipment powers, if the power output of the first power supply unit is less than the operating power of power consumption equipment, the second power supply unit selected by control appliance 01, and by this second power supply unit and the first power supply unit simultaneously for power consumption equipment is powered, wherein, the power output of this second power supply unit and the power output sum of the first power supply unit are more than or equal to the operating power of power consumption equipment, and this second power supply unit can be DC suppling equipment 02, a power supply unit in AC power supply device 03 and battery supply set 04 except the first power supply unit, so, second power supply unit and the first power supply unit just can simultaneously for power consumption equipment be powered, ensure to provide normal power supply for power consumption equipment.

Such as, the power output of the first power supply unit that control appliance 01 is determined is 1000W, but the operating power of power consumption equipment is 1200W, so, power output due to the first power supply unit is less than the operating power of power consumption equipment, therefore, control appliance 01 also need to determine to meet be greater than 200W the second power supply unit together with the first power supply unit for power consumption equipment is powered.

Certainly, be that power consumption equipment is powered at the first power supply unit, or, in the process that second power supply unit is powered for power consumption equipment together with the first power supply unit, may occur that the power supply unit of powering breaks down situation about cannot power, now, control appliance 01 still applicable said method power output be not 0 can determine that new power supply unit is that power consumption equipment is powered in emergency electric supply unit.

Further, before the first power supply unit determined by control appliance 01, control appliance 01 can also identify the different systems of different loads type in power consumption equipment, for the power consumption equipment of different loads type and different systems, control appliance 01 all can provide corresponding power supply to export, like this, this electric control system provided can the power consumption equipment of compatible multiple loadtype and load standard, improves the power supplying efficiency of whole system.

Concrete, if power consumption equipment is DC load, the control appliance 01 monitoring voltage of power consumption equipment and the charging current of battery supply set 04, and according to the standard of monitoring result determination DC load, rated power due to DC load is certain, therefore, before power consumption equipment reaches rated power, the voltage of power consumption equipment becomes positive correlation with the charging current of battery supply set 04; After power consumption equipment reaches rated power, the voltage of power consumption equipment becomes negative correlation with the charging current of battery supply set 04, so the magnitude of voltage corresponding to critical point of these two kinds of correlation circumstances is exactly the rated voltage of DC load, such as, the standard of this DC load can comprise 240V DC load, 336V DC load and 48V DC load etc.

If power consumption equipment is AC load, control appliance 01 instruction AC power supply device 03 loads test voltage to this AC load and tests, because the voltage of AC load and phase place change according to certain rule, therefore can by the standard of the phase place situation of change determination AC load of AC load under test voltage, the standard of this AC load can comprise 120V AC load, 220V AC load, 230V AC load, 240V AC load etc.

Or, the mark of the power consumption equipment that all right receiving terminal apparatus 05 of control appliance 01 sends, this mark comprises the type of power consumption equipment and standard, and (namely power consumption equipment is DC load or AC load, and the load standard of different loads type), like this, control appliance 01 just according to the mark of power consumption equipment, can directly determine type and the standard of power consumption equipment.

Because control appliance 01 determines loadtype and the load standard of power consumption equipment, therefore, control appliance 01 determines that the first power supply unit is power consumption equipment when powering, and corresponding supply power mode can be selected to power.Such as: if the loadtype of power consumption equipment is AC load, control appliance 01 standard according to AC load, indicates the first power supply unit to provide the alternating current needed for the standard of AC load to power consumption equipment; If the loadtype of power consumption equipment is DC load, control appliance 01 standard according to DC load, indicates the first power supply unit to provide the direct current needed for the standard of DC load to power consumption equipment.

So far, control appliance gets the power output of DC suppling equipment, the power output of AC power supply device, after the power output of battery supply set and the operating power of power consumption equipment, tactic from described DC suppling equipment, described AC power supply device and described battery supply set determine that the first power supply unit is that power consumption equipment is powered, when the power output of the first power supply unit is less than the operating power of power consumption equipment, namely when the power output of the first power supply unit cannot meet the operating power of power consumption equipment, control appliance determines the second power supply unit from other power supply units except the first power supply unit, and indicate the first power supply unit and the second power supply unit to power for described power consumption equipment simultaneously, like this, owing to providing multiple power supply input mode, it is that power consumption equipment is powered that control appliance just can reasonably choose at least one power supply unit according to the operating power of power consumption equipment, avoid in prior art, owing to too relying on the Alternating Current Power Supply input mode in electrical network, and the electric power system that may cause cannot ensure the problem of power consumption equipment normal power supply, make the power supply input mode in electric power system more diversified, improve the power supplying efficiency of electric power system simultaneously.

Further, as shown in Figure 3, for the internal structure schematic diagram of DC suppling equipment 02, wherein, this DC suppling equipment 02 comprises direct-flow input circuit, DC (direct current, the direct current)-DC circuit be connected with direct-flow input circuit, DC-AC (alternatecurrent exchanges) circuit be connected with DC-DC circuit.

Further, the output of DC-DC circuit can be connected with battery supply set 04, and the output of DC-DC circuit can also be connected with direct-flow electricity utilization apparatus, and the output of DC-AC circuit can be connected with AC electric equipment.

Concrete, the power supply instruction that direct-flow input circuit sends according to control appliance 01 provides direct current input current; If the loadtype of power consumption equipment is DC load, DC-DC circuit carries out copped wave to the direct current input current that described direct current input module exports, and obtains the direct current after copped wave and exports DC load to; If the loadtype of described power consumption equipment is AC load, the direct current after the copped wave that DC-AC circuit exports DC-DC circuit carries out inversion, obtains the alternating current after inversion and also exports AC load to.

Should be understood that, shown in Fig. 3 is only a kind of schematic diagram of the internal structure of DC suppling equipment 02, when power consumption equipment only includes direct-flow electricity utilization apparatus, also can DC-AC circuit in adaptive deletion Fig. 3, and the present invention does not impose any restrictions this.

Wherein, this direct-flow input circuit can comprise at least one in solar powered unit, floor heating power supply unit, natural gas power supply unit, direct current machine power supply unit and fuel cell-powered unit, wherein, fuel cell (Fuel Cell) is a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT) chemical energy be present in fuel and oxidant being converted into electric energy, just can produce direct current by sending fuel and air to fuel cell respectively.

Concrete, if direct-flow input circuit comprises solar powered unit, so this DC suppling equipment 02 can also comprise MPPT (Maximum Power Point Tracking, controller for solar), wherein, the input of described MPPT is connected with described direct-flow input circuit, and the output of described MPPT is connected with described DC-DC circuit.The full name of MPPT controller is MPPT maximum power point tracking controller for solar, it can the generating voltage of solar panels in the solar powered unit of detecting real-time, and follow the trail of the current value of ceiling voltage, to ensure that solar powered unit is with maximum power output DC power supply, effectively can solve life and the commercial power of remote districts that normal grid can not cover and tourist area, reduce the pollution to environment.

So far, the power supply instruction that DC suppling equipment 02 is sent by receiving control apparatus 01, and according to loadtype adaptive selection direct current supply pattern, for power consumption equipment provides required alternating current or direct current, so, to avoid in prior art simple when relying on the mode of Alternating Current Power Supply to power to power consumption equipment, because the interchange too relied in electrical network is powered for input, and the electric power system that may cause cannot be normally problem that power consumption equipment is powered, solve the problem that current supply power mode input mode is comparatively single, and improve the power supplying efficiency of electric power system.Meanwhile, because DC suppling equipment 02 can make full use of the environmental protection such as solar energy, reproducible clean energy resource, DC suppling equipment 02 is made to have more energy saving and the feature of environmental protection.

Further, as shown in Figure 4, for the internal structure schematic diagram of AC power supply device 03, wherein, this DC suppling equipment 02 comprises ac input circuit, the AC-DC circuit be connected respectively with ac input circuit and bypass circuit, and the DC-DC circuit be connected respectively with AC-DC circuit and DC-AC circuit.

It should be noted that, the DC-DC circuit of AC power supply device 03 and the DC-DC circuit of DC-AC circuit and DC suppling equipment 02 and DC-AC circuit can be separate, like this, AC power supply device 03 and DC suppling equipment 02 are independent of each other in running, break down once AC power supply device 03 or DC suppling equipment 02, the normal work of another power supply unit can not be affected.

Certainly, DC-DC circuit and the DC-AC circuit of the DC-DC circuit of AC power supply device 03 and DC-AC circuit and DC suppling equipment 02 also can be overlapping, that is, AC power supply device 03 and DC suppling equipment 02 can use DC-DC circuit and DC-AC circuit jointly, to reduce the complexity of electric control system.

Concrete, the power supply instruction that ac input circuit sends according to control appliance 01 provides industrial-frequency alternating current; Now, whether control appliance 01 can detect this industrial-frequency alternating current normal, whether the civil power namely in current electric grid is normal, if industrial-frequency alternating current meets the loading demand (voltage of such as industrial-frequency alternating current and phase place size meet voltage needed for power consumption equipment and phase place size) of power consumption equipment, bypass circuit is then direct flows to power consumption equipment by the industrial-frequency alternating current that described ac input circuit exports, to complete the power supply process to power consumption equipment.Wherein, bypass circuit can switch to industrial-frequency alternating current (civil power) on a loop, supply electric power is continued to load equipment by bypass circuit, and when civil power does not meet the loading demand of power consumption equipment, switch on another loop and use AC-DC circuit, DC-DC circuit and DC-AC circuit normally to work on another loop.

Accordingly, if industrial-frequency alternating current does not meet the loading demand of power consumption equipment, directly cannot utilize the civil power in electrical network, now, AC-DC circuit carries out rectification to the industrial-frequency alternating current that ac input circuit exports, and obtains the direct current after rectification; If the loadtype of described power consumption equipment is DC load, DC-DC circuit then carries out copped wave to the direct current after the rectification of AC-DC circuit output, obtains the direct current after copped wave and also exports direct-flow electricity utilization apparatus to; If the loadtype of described power consumption equipment is AC load, DC-AC circuit then carries out inversion to the direct current after the rectification of AC-DC circuit output, obtains the alternating current after inversion and also exports AC electric equipment to.

Should be understood that, shown in Fig. 4 is only a kind of schematic diagram of the internal structure of AC power supply device 03, when power consumption equipment only includes AC electric equipment, and also can DC-DC circuit in adaptive deletion Fig. 4; When power consumption equipment only includes direct-flow electricity utilization apparatus, also can DC-AC circuit in adaptive deletion Fig. 4; Certainly, also can bypass circuit in adaptive deletion Fig. 4, still can realize the power supply process to AC electric equipment, the present invention does not impose any restrictions this.

Wherein, ac input circuit comprises single phase power supply unit and three phase supply unit, concrete, if the operating power of power consumption equipment is less than predetermined threshold value, the power supply instruction that single phase power supply unit then sends according to control appliance 01 provides single phase industrial frequence alternating current; If the operating power of power consumption equipment is greater than predetermined threshold value, the power supply instruction that three phase supply unit then sends according to control appliance 01 provides three-phase main-frequency alternating current.

Further, this three phase supply unit can be divided into again three-phase to have zero line power supply unit and three-phase without zero line power supply unit, because three-phase alternating-current supply is identical by three frequencies, amplitude is equal, phase place successively mutual deviation 120 ° interchange electromotive force composition power supply, its supply power mode can be three live wires and a zero line, also can be three live wires, some power consumption equipments do not need connecting to neutral line, and some power consumption equipments need connecting to neutral line, therefore, when the output of electric control system mount be the power consumption equipment of three-phase without zero line time, three-phase can be used to power without zero line power supply unit, when the output of electric control system mount be three-phase have a power consumption equipment of zero line time, three-phase can be used to have zero line power supply unit to power, in addition, in the engineering of powering there being the power consumption equipment of zero line to three-phase, whether the zero line that control appliance 01 can also detect power consumption equipment in real time disconnects.Once disconnect, control appliance 01 generates warning message so that maintenance personal keeps in repair the zero line disconnected in time.

So far, the power supply instruction that AC power supply device 03 is sent by receiving control apparatus 01, and according to loadtype adaptive selection Alternating Current Power Supply pattern, for power consumption equipment provides required alternating current or direct current, meanwhile, because control appliance 01 is according to the operating power of power consumption equipment, for AC power supply device 03 reasonably selects single phase power supply or three phase supply, avoid the wasting of resources, substantially increase the power supplying efficiency of electric control system.

In a step 102, after control appliance gets the operating power of the power output of DC suppling equipment, the power output of AC power supply device, the power output of battery supply set and power consumption equipment, control appliance can, according to preset strategy, select a power supply unit to be that power consumption equipment is powered as the first power supply unit from DC suppling equipment, AC power supply device and battery supply set.

Concrete, when the first power supply unit is DC suppling equipment, control appliance then sends power supply instruction to DC suppling equipment, to make DC suppling equipment to use at least one generation current in solar powered unit, floor heating power supply unit, natural gas power supply unit, direct current machine power supply unit and fuel cell-powered unit according to power supply instruction, and DC-DC conversion and/or DC-AC conversion are carried out to power to power consumption equipment to the electric current produced.

When the first power supply unit is AC power supply device, control appliance then sends power supply instruction to AC power supply device, to make AC power supply device use single phase power supply unit or three phase supply unit generation current according to power supply instruction, and AC-DC conversion and/or DC-AC conversion are carried out to power to power consumption equipment to the electric current produced.

When the first power supply unit is battery supply set, control appliance then sends power supply instruction to battery supply set, uses the electric energy self stored to power to power consumption equipment to make battery supply set according to power supply instruction.

After execution of step 102, control appliance needs the power output detecting this first power supply unit whether to be less than the operating power of power consumption equipment, namely whether the power output of the first power supply unit meets the need for electricity of power consumption equipment, if the power output of the first power supply unit is more than or equal to the operating power of power consumption equipment, then illustrate that the power output of the first power supply unit can meet the need for electricity of power consumption equipment, therefore continuation use first power supply unit is powered to power consumption equipment; If the power output of the first power supply unit is less than the operating power of power consumption equipment, then illustrate that the power output of the first power supply unit can not meet the need for electricity of power consumption equipment, now, control appliance can perform step 103.

In step 103, if the power output of the first power supply unit is less than the operating power of power consumption equipment, the second power supply unit then selected by control appliance, and can simultaneously for power consumption equipment is powered by this second power supply unit and the first power supply unit, wherein, the power output of this second power supply unit and the power output sum of the first power supply unit are more than or equal to the operating power of power consumption equipment, and, this second power supply unit is DC suppling equipment, a power supply unit in AC power supply device and battery supply set except the first power supply unit, like this, second power supply unit and the first power supply unit can simultaneously for power consumption equipment be powered, to meet the need for electricity of power consumption equipment.

Exemplary, the first power supply unit that control appliance is determined is DC suppling equipment, the power output of this DC suppling equipment is 4000W, but the operating power of power consumption equipment is 5000W, so, power output due to the first power supply unit is less than the operating power of power consumption equipment, therefore, control appliance then need determine in AC power supply device and battery supply set that power output is greater than the power supply unit of 1000W as the second power supply unit, such as, the power output of AC power supply device is 2000W, the power output of battery supply set is 800W, so, control appliance then determines that AC power supply device is the second power supply unit, and with the first power supply unit simultaneously for power consumption equipment is powered, certainly, if the power output of AC power supply device and battery supply set is all large and 2000W, control appliance then can determine that AC power supply device or battery supply set are the second power supply unit at random.

In addition, see Fig. 1 or Fig. 2, because battery supply set is connected with DC suppling equipment or AC power supply device, therefore, control appliance can send charging instruction to DC suppling equipment or AC power supply device, battery supply set is charged according to charging instruction to make DC suppling equipment or AC power supply device, so, once DC suppling equipment or AC power supply device break down, when cannot power to power consumption equipment, control appliance can be powered directly to power consumption equipment by pilot cell power supply unit, to guarantee power consumption equipment not power-off.

204, the power supply instruction that battery supply set sends according to control appliance is powered to power consumption equipment.

If 205 electric control systems do not break down, whether the power output that control appliance then detects solar power supply unit is greater than threshold value.

If the power output of 206 solar power supply units is greater than threshold value, control appliance then determines that solar power supply unit is the first power supply unit, and sends power supply instruction according to the load standard of power consumption equipment to this solar power supply unit.

If 207a power consumption equipment is AC load, solar power supply unit then provides the alternating current of required load standard to power consumption equipment according to power supply instruction.

If 207b power consumption equipment is DC load, solar power supply unit then provides the direct current of required load standard to power consumption equipment according to power supply instruction.

It should be noted that, the DC suppling equipment related in embodiments of the invention is described for solar power supply unit, should be understood that, the DC suppling equipment of other types also adaptively can be applicable to the method that the embodiment of the present invention provides, and the present invention does not impose any restrictions this.

In step 201, the method for the operating power of control appliance acquisition power consumption equipment see previous embodiment one, can repeat no more herein.

In step 202., the method for the load standard of control appliance determination power consumption equipment has multiple, specifically see previous embodiment one and embodiment two, can repeat no more herein.

If step 203 is to 212, embodiments of the invention provide a kind of feasible control appliance and determine that the first power supply unit and the second power supply unit are the concrete grammar that power consumption equipment is powered, should be understood that, control appliance determines that the first power supply unit and the second power supply unit are that the method that power consumption equipment is powered is a variety of in addition, and the present invention is not restricted this.

Concrete, in step 203, whether control appliance can have electric current to export by the output detecting each power supply unit, judges whether current electric control system breaks down, if do not have electric current to export, then electric control system breaks down, and so, can perform step 203 to 204, if there is electric current to export, then electric control system does not break down, and accordingly, can perform step 205 to 212.

Wherein, if electric control system breaks down, that is the power output of solar power supply unit and the power output of AC power supply device are 0, so, control appliance is now in order to ensure power consumption equipment not power down, determine that battery supply set is the first power supply unit, and send power supply instruction to battery supply set, power to power consumption equipment to make battery supply set.

In step 204, be the first power supply unit at control appliance determination battery supply set, and to battery supply set send power supply instruction after, the power supply that battery supply set sends according to control appliance indicates the voltage and current providing suitable standard to power consumption equipment, to meet the watt level needed for power consumption equipment.

Concrete, owing to storing electric energy in battery supply set, therefore, when electric control system breaks down, battery supply set can power to ensure power consumption equipment not power down directly to power consumption equipment.When power consumption equipment is DC load, due to battery supply set output is exactly direct current, therefore battery supply set can directly for DC load be powered, when power consumption equipment is AC load, due to battery supply set output is direct current, therefore, the direct current that battery supply set exports need be carried out DC-AC conversion in DC-AC circuit, obtain the alternating current needed for AC load.

In addition, see Fig. 1 or Fig. 2, because the output of battery supply set with solar power supply unit or AC power supply device is connected, therefore, control appliance can send charging instruction to solar power supply unit or AC power supply device, battery supply set is charged according to charging instruction to make solar power supply unit or AC power supply device, so, once solar power supply unit or AC power supply device break down, when cannot power to power consumption equipment, control appliance can be powered directly to power consumption equipment by pilot cell power supply unit, to guarantee power consumption equipment not power-off.

In step 205, if electric control system does not break down, control appliance then prioritizing selection solar power supply unit is that the first power supply unit is powered to power consumption equipment, now, control appliance needs whether be greater than threshold value according to the power output of solar power supply unit, judges whether to use solar power supply unit to power for power consumption equipment.

And the power output of solar power supply unit depends on current weather conditions, when sunlight ray reaches certain index, because the solar panels in solar power supply unit can convert solar energy into the electric energy of certain power, therefore, if now the power output of solar power supply unit is greater than threshold value, then perform step 206 to 209.Accordingly, if now the power output of solar power supply unit is less than threshold value, then perform step 210 to 212.

In step 206, if the power output of solar power supply unit is greater than threshold value, control appliance then determines that solar power supply unit is the first power supply unit, and send power supply instruction according to the load standard of power consumption equipment to solar power supply unit, power to power consumption equipment according to power supply instruction to make solar power supply unit.

Wherein, contain the load standard of power consumption equipment in this power supply instruction, power according to the load standard of power consumption equipment to make solar power supply unit.

In step 207a, if power consumption equipment is AC load, and the load standard having determined power consumption equipment in step 202. (such as, 220V AC load or 380V AC load etc.), so, solar power supply unit is after receiving the power supply instruction to this AC load, from the solar powered unit solar power supply unit, direct current is exported according to power supply instruction, copped wave is carried out again by the direct current of output input DC-DC circuit, obtain the direct current after copped wave, now, solar power supply unit carries out inversion by the direct current input DC-AC circuit after copped wave again, obtain the alternating current after inversion, finally, solar power supply unit exports the alternating current after inversion to this AC load, complete the power supply process to this AC load.

In step 207b, if power consumption equipment is DC load, and the load standard having determined power consumption equipment in step 202. (such as, 220V DC load or 48V DC load etc.), so, solar power supply unit is after receiving the power supply instruction to this DC load, from the solar powered unit solar power supply unit, direct current is exported according to power supply instruction, and carry out copped wave by the direct current of output input DC-DC circuit, export the direct current after copped wave to this DC load, complete the power supply process to this DC load.

Exemplary, if power consumption equipment is 240V DC load, solar power supply unit then provides 240V direct current according to direct current supply instruction to power consumption equipment; If the DC load type of power consumption equipment is 336V DC load, solar power supply unit then provides 336V direct current according to direct current supply instruction to power consumption equipment; If the DC load type of power consumption equipment is 48V DC load, solar power supply unit then provides 48V direct current according to direct current supply instruction to power consumption equipment.

Optionally, in step 206b and 206c, the output of solar powered unit can also be connected with the input of controller for solar, the output of controller for solar can be connected with the input of DC-DC circuit, like this, solar power supply unit is after receiving the power supply instruction to this DC load, from the solar powered unit solar power supply unit, direct current is exported according to power supply instruction, and the direct current exported is inputted in controller for solar, make solar powered unit with maximum power output DC power supply, and then carry out copped wave by the direct current input DC-DC circuit of controller for solar output, because controller for solar can the piezoelectric voltage of solar panels in the solar powered unit of detecting real-time, and follow the trail of ceiling voltage current value, therefore, controller for solar can make solar powered unit with maximum power output DC power supply, to ensure the maximal efficiency of solar power supply unit, effectively can solve life and the commercial power of the remote districts that normal grid can not cover, and reduce environmental pollution.

In a step 208, if the power output of solar power supply unit is less than the operating power of power consumption equipment, control appliance then determines the second power supply unit from AC power supply device and battery supply set, and sends power supply instruction according to the load standard of power consumption equipment to this second power supply unit.

Wherein, control appliance determines that the method for the second power supply unit can see embodiment one and embodiment two, so place repeats no more.

In step 209, after the second power supply unit determined by control appliance, send power supply instruction to this second power supply unit, the second power supply unit provides the electric current of required load standard to power consumption equipment according to solar power supply unit transmission power supply instruction.

Concrete, if the second power supply unit is AC power supply device, and power consumption equipment is when being AC load, AC power supply device is after receiving the power supply instruction to this AC load, according to power supply instruction output AC electric current from the AC input cell AC power supply device, rectification is carried out again by the alternating current of output input AC-DC circuit, obtain the direct current after rectification, inversion is carried out again by the direct current input DC-AC circuit after rectification, obtain the alternating current after inversion, finally, AC power supply device exports the alternating current after inversion to this AC load, finally complete the power supply process to this AC load.

Equally, if the second power supply unit is AC power supply device, and power consumption equipment is DC load, so, AC power supply device is after receiving the power supply instruction to this DC load, according to power supply instruction output AC electric current from the AC input cell AC power supply device, rectification is carried out again by the alternating current of output input AC-DC circuit, obtain the direct current after rectification, copped wave is carried out again by the direct current input DC-DC circuit after rectification, obtain the direct current after copped wave, finally, AC power supply device exports the direct current after copped wave to this DC load, finally complete the power supply process to this DC load.

Similar, if the second power supply unit is battery supply set, and power consumption equipment is when being AC load, battery supply set is after receiving the power supply instruction to this AC load, and the electric current exported due to battery supply set is direct current, therefore, need the direct current to battery supply set exports to carry out inversion in DC-AC circuit, obtain the alternating current after inversion, finally, export the alternating current after inversion to this AC load, finally complete the power supply process to this AC load.

If the second power supply unit is battery supply set, and power consumption equipment is when being DC load, battery supply set is after receiving the power supply instruction to this DC load, the electric current exported due to battery supply set is direct current, therefore, battery supply set can export direct current directly to DC load and complete power supply process to this DC load.Certainly, because the standard of DC load may be different from the standard that battery supply set exports, therefore, need the direct current to battery supply set exports to carry out copped wave in DC-DC circuit, obtain the direct current of the standard that to conform to power consumption equipment.

Can find out, the power supply instruction that solar power supply unit is sent by receiving control apparatus, AC power supply device or battery supply set is coordinated to provide required alternating current or direct current for power consumption equipment, so, to avoid in prior art simple when relying on the mode of Alternating Current Power Supply to power to power consumption equipment, owing to relying on merely the Alternating Current Power Supply input mode in electrical network, and the electric power system that may cause cannot be just normally problem that power consumption equipment is powered, current power supply input style can be widened, and improve the power supplying efficiency of electric power system.Meanwhile, because solar power supply unit can make full use of the environmental protection such as solar energy, reproducible clean energy resource, make solar power supply unit according to having energy saving and the feature of environmental protection.

In step 210, if the power output of solar power supply unit is less than threshold value, control appliance then determines that AC power supply device is the first power supply unit.

In step 211, after control appliance determination AC power supply device is the first power supply unit, whether first control appliance detects current industrial-frequency alternating current normal, and whether the civil power namely in current electric grid is normal.Concrete, control appliance can obtain the harmonic value of civil power in electrical network and magnitude of voltage judges whether current civil power meets the need for electricity of power consumption equipment, if current industrial-frequency alternating current meets the loading demand of power consumption equipment, the voltage of namely current industrial-frequency alternating current conforms to (that is civil power is normal) with harmonic wave with the voltage of power consumption equipment with harmonic wave, so, industrial-frequency alternating current in electrical network directly can be flowed to power consumption equipment by bypass circuit by control appliance, to complete the power supply process to power consumption equipment.

Certainly, because the civil power in electrical network is alternating current, therefore, if power consumption equipment is DC load, so, also need in AC-DC circuit, to carry out rectification to the industrial-frequency alternating current in electrical network, direct current after rectification is flowed to power consumption equipment, to complete the power supply process to power consumption equipment.

In the step 212, if current industrial-frequency alternating current does not meet the loading demand of power consumption equipment, control appliance then sends power supply instruction, to make AC power supply device according to the operating power of power consumption equipment for power consumption equipment carries out single phase power supply or three phase supply to AC power supply device.

Concrete, if current industrial-frequency alternating current does not meet the loading demand of power consumption equipment, according to the operating power of power consumption equipment, control appliance can judge whether the operating power of power consumption equipment arrives the preset threshold value of three phase supply further, if the operating power of power consumption equipment is less than the preset threshold value of three phase supply, namely single phase power supply is used can to meet the operating power of power consumption equipment, so, AC power supply device uses single phase power supply unit to provide electricity consumption for power consumption equipment.Wherein, if power consumption equipment is AC load, so, the alternating current that single phase power supply unit exports is inputed to AC-DC circuit and carries out rectification by AC power supply device, again the direct current input DC-AC circuit after rectification is carried out inversion, obtain the alternating current after inversion, finally, export the alternating current after inversion to this AC load, finally complete the power supply process to this AC load; If power consumption equipment is DC load, so, the alternating current that single phase power supply unit exports is inputed to AC-DC circuit and carries out rectification by AC power supply device, again the direct current input DC-DC circuit after rectification is carried out copped wave, finally, export the direct current after copped wave to this DC load, finally complete the power supply process to this DC load.

Accordingly, if the operating power of power consumption equipment is greater than the preset threshold value of three phase supply, namely need to use three phase supply just can meet the operating power of power consumption equipment, so, AC power supply device uses three phase supply unit to provide electricity consumption for power consumption equipment.Wherein, if power consumption equipment is AC load, so, the alternating current that three phase supply unit exports is inputed to AC-DC circuit and carries out rectification by AC power supply device, again the direct current input DC-AC circuit after rectification is carried out inversion, obtain the alternating current after inversion, finally, export the alternating current after inversion to this AC load, finally complete the power supply process to this AC load; If power consumption equipment is DC load, so, the alternating current that three phase supply unit exports is inputed to AC-DC circuit and carries out rectification by AC power supply device, again the direct current input DC-DC circuit after rectification is carried out copped wave, finally, export the direct current after copped wave to this DC load, finally complete the power supply process to this DC load.

Can find out, AC power supply device and control appliance cooperatively interact, for power consumption equipment provides required alternating current or direct current, simultaneously, because control appliance is according to the operating power of power consumption equipment, for AC power supply device reasonably selects single phase power supply or three phase supply, avoid the wasting of resources, substantially increase the power supplying efficiency of electric control system.
