Step S1: monitoring assembly gathers the current parameters of solar control assembly output respectively by Hall current sensor group, the voltage parameter of solar control assembly output is gathered by Hall voltage transducer group, the frequency parameter of inversion assembly output AC electric energy is gathered by frequency sensor group, the first boosting parameter of the first booster circuit output is gathered by the first booster voltage testing circuit, the second boosting parameter of the second booster circuit output is gathered by the second booster voltage testing circuit, the phase parameter of the second booster circuit output AC electric energy is gathered by the second boosting phase detecting circuit, the grid-connected current parameter of grid-connected switch is gathered by grid-connected current testing circuit, the voltage parameter of utility grid is gathered by power grid voltage detection circuit, the phase parameter of utility grid is gathered by power grid phase detection circuit, control device is integrated or conversion process image data, by interconnective collection control communication interface, data after process are sent to increasing apparatus by boosting communication interface,
Step S2: the control circuit in increasing apparatus, logical circuit judge that whether the frequency parameter of current parameters that solar control assembly exports, voltage parameter that solar control assembly exports, inversion assembly output AC electric energy is normal, if all normal, control circuit exports control signal and connects input protection switch by drive circuit, in the access grid-connected power generation circuit of alternating voltage that solar battery group exports, then control circuit output drive signal the first booster circuit is started working by drive circuit; If any one parameter is abnormal, disconnects input protection switch and return step S1;
Step S3: control circuit judges that the first boosting parameter that the first booster circuit exports is whether in setting range, if then output drive signal make the second booster circuit start working by drive circuit; Then disconnect input protection circuit if not and return step S1;
Step S4: control circuit judges whether the voltage parameter of the second boosting parameter that the second booster circuit exports and utility grid is in setting range, simultaneously whether in the same way control circuit judges the phase parameter of the voltage parameter of utility grid and utility grid, if be all, control circuit output control signal also closes grid-connected switch by drive circuit the second booster circuit is electrically connected with utility grid; If any one parameter does not meet the demands, disconnect input protection circuit and return step S1;
Step S5: control circuit judges grid-connected current parameter whether in setting range, if then grid-connected switch remains closed and the boosting communication interface of control circuit by being interconnected, collection control communication interface sends feedback signal to control device, control device is set up by remote communication module and power-management centre and is long-rangely connected and carries out Long-distance Control to increasing apparatus to the grid-connected power supply of utility grid by centralized control center by power-management centre, now, the electric energy that solar battery group transforms passes through lightning protection component successively, controller for solar, inversion assembly, batch meter, the alternating current that loop exports that generates electricity by way of merging two or more grid systems is coupled to utility grid and carries out grid-connected power supply, if grid-connected current parameter is not in setting range, disconnects grid-connected switch and return step S1,
Step S6: in the process of grid-connected power supply, if control circuit judges that any one parameter that monitoring assembly gathers occurs abnormal, then exports control signal and disconnects input protection switch, grid-connected switch return step S1, stop grid-connected power supply.
