Scan pattern instruction（S1）, then whether the intensity of sunshine for judging sunshine recorder 311 ... measured by 3N1 do not change（S2）,
In the case of having sunshine change, then the I-V curve end of scan（S6）.In the case of there is no sunshine change in S2, judge whether
There is no system exception（S3）, in the case where there is system exception, then the I-V curve end of scan（S6）.There is no system different in S3
In the case of often, then I-V curve scanning is performed（S4）, and judge the value of the scanning whether more than limits value（S5）.In S5
In more than the limits value in the case of, then the I-V curve end of scan（S6）.Situation more than limits value is not in S6
Under, S2 is returned to, judges whether no sunshine change.In addition, in S6, scanning voltage Vref_scan or sweep current Iref_
In the case that scan is not in the limits value Vdc_limit or more than Idc_limit of setting, then continue I-V curve scanning, at place
In the case of limits value Vdc_limit or more than Idc_limit, then the I-V curve end of scan.
I-V curve scanning is similarly carried out as shown in Figure 15 with Figure 14.If during I-V curve is scanned
Sunshine is changed, then I-V curve scanning stops.Figure 15 be when each group is to carry out I-V curve scanning,
In 2N selected the step of is added in power governor 21 ... between Figure 14 S1 and S2., can be freely in the selection
Select odd number, even number, the tandem converter of solar cell (PV) component side（string converter）Deng.Except above-mentioned
The step of beyond, it is all identical with Figure 14, therefore identical label is added to same section, and the description thereof will be omitted.
Figure 18 is used for the actuation time for illustrating to perform above-mentioned I-V curve scanning in the time of one day.In Figure 18, PCS
Actuation time refers to the time that PCS is acted in the time of one day.I-V curve scanning periodic time referred in PCS actuation times
In regularly carry out time of I-V curve scanning.Intensity of sunshine>Setting intensity of sunshine and I-V curve scanning, which perform triggering, is
Refer to, in the case that intensity of sunshine is more than the intensity of sunshine of setting in above-mentioned periodic time, output I-V curve scanning, which is performed, touches
Hair, and in the case where intensity of sunshine is less than the intensity of sunshine of setting, I-V curve scanning is not exported and performs triggering.By to this
Figure 18 thought is extended, it is additional using external data as function information such as reading weather forecast of reference function,
Describe so as to carry out the efficient curve for determining to determine schedule.
