Embodiment
Fig. 1 illustrates a reduced graph of an inside plant with connection box, wherein there is a PV system.
The current lead of an energy supply network 1 is sent an inside plant 3 at intraventricular delivery point 2 (being shown as a dotted line in the drawings) place.This inside plant comprises a current drain counter 4, and this current drain counter is arranged in a panel box as overcurrent insures with the safety apparatus do not shown at this usually together with failure current protection switch device.In the framework of inside plant, panel box is usually also referred to as proof box.
In an illustrated embodiment, not only this energy supply network 1 also has this inside plant to be all embodied as three-phase, has a neutral conductor N and three phase conductor L1, L2, L3.For succinct reason, an extra earth conductor is not shown at this.Within this inside plant, there is multiple customer, be exemplarily shown as three single-phase customers 5 at this.
In addition, also there is the part of a PV system as this inside plant 3, this PV system comprises a PV generator 6 and an inverter be attached thereto 7.PV generator 6 such as can have multiple PV module being arranged in roof.Inverter 7 be usually arranged in this panel box vicinity or in fact in this panel box.Inverter 7 connects with these conductors of inside plant 3 with output interface equally.In an illustrated embodiment, inverter 7 is designed to single-phase and connects with this phase conductor L2 and this neutral conductor N at this.It is, however, also possible that the design of a kind of three-phase of inverter 7.
Inverter 7 is therefore different from when being suitable for the PV system of carrying out storing, and is not that the storage counter by separating is connected with this energy supply network 1.In shown design, therefore this PV system is adapted for the electric energy producing and directly consumed by customer 5.Storage in this energy supply network 1 is not set, and especially can also suppresses pointedly.
In order to stop PV system to provide the more electric current consumed than the customer 5 connected with phase conductor L2, being provided with a control device 8 and adjusting for the power of inverter 7.When needed, control device 8 adjusts the power of inverter 7, makes inverter 7 not reoffer the more electric current of customer 5 actual consumption that comparison is answered.Can propose at this, the power provided by PV generator 6 carries out throttling by being changed on the direction of its open-circuit voltage or on the direction of its short-circuit voltage PV generator 6 working point.Alternatively or extraly can also propose, the excessive power of PV generator 6 transmits in an energy storage device arrangement, such as, in a battery storage device (not showing in FIG) by inverter 7.In addition, when---mode manually or automatically to control---connects other customer pointedly when PV generator 6 side too much provides available electrical power, the actual consumption to electric power is improved thus.Not depending on that the power sent by PV generator 6 reduces is to be undertaken by the change of the working point of PV generator 6 or by the current delivery by PV generator 6 is this or be switched on or switched off extra electric consumption device and produced and mate between required power to reservoir now, control device 8 ensure that, this customer 5 or the electric current needed for these customers 5 are transmitted in the conductor of inside plant 3 by inverter 7.For this purpose, arrange a measurement mechanism 10, electric current at least on phase L2 and optionally on phase L1 and L3, that flow from counter 4 to inside plant 3 measured by this measurement mechanism.At this, not only determine that the size of the electric current flowed also determines its direction.Direction is interpreted as the direction in the flowing of inverter place net power.
The acquisition of flow of power is carried out must be able to be multiplied with magnitude of voltage by the voltage measurement parallel with current measurement and electric current the most under normal circumstances.By the parallel mensuration to these two values that carry out, that depend on the time, impliedly also take into account the relative phase again between electric current and voltage.But it is also contemplated that the method for simplification.Such as the size of voltage can be regarded as constant in fact, because the voltage fluctuation in energy supply network is typically less than +/-10%.So measure size of current (amplitude or effective value) and be with this arc in phase about this electric current or deflect the information of 180 ° mutually just enough.Being categorized as these two phase places is the directions being finally enough to determine this flow of power.In order to effectively get rid of storage in each case, meaningfully, a value in the lower end of adopted voltage range (voltage in this energy supply network typically fluctuates within the scope of this) is adopted.
The adjustment of PV system can be carried out as follows, namely for each in these phase conductors L1, L2, L3, forbids the flow of power from this inside plant 3 to the direction of this energy supply network 1.This corresponds to a relatively harsh requirement, that is, no matter observe which phase conductor L1, L2, L3, all get rid of the flow of power on this energy supply network 1 direction for this phase conductor L1, L2, L3 always.But, be alternative in this, also likely adjust this PV system, make on the direction of this energy supply network 1, get rid of net power flowing.In the case, such as, when a flow of power at least when being compensated, can carry out the flow of power on a phase conductor L1 on the direction of this energy supply network 1 by from the flow of power of this energy supply network 1 on the direction of this inside plant 3 in correspondingly other phase conductor (at this: L2, L3).Ensure that in this way, at least amounted to by all phase conductor L1, L2, L3 and on the direction of this energy supply network 1, do not carry out flow of power and therefore eliminate the net power flowing on the direction of this energy supply network 1.According to the requirement of Virtual network operator, this storage or may be also admissible by certain amount for certain time span.
Although illustrate the three-phase embodiment that has three phase conductors L1, L2, L3 in FIG, the utility model is not limited to the connection of this indoor interface to the only three-phase of this energy supply network 1.So also can be the connection of the L1-Ln of the phase conductor with other numbers arbitrary, wherein n provides the number of phase conductor.Especially for there is limited electric consumption device 5 number or buildings for the limited power receiving ability from open energy supply network 1, the electrical interface of buildings also may only by a phase conductor L1 (except neutral conductor N).
