摘要： In a solar power generation system having an inverter, if a smoothing capacitor in the inverter degrades, the operation of the inverter is interrupted, and a loss in the amount of power generation occurs inevitably. To prevent this loss, a degradation determination section (211) and output suppressing section (212) are provided in an inverter (2). If the degradation determination section (211) determines a degradation in capacitor (24), the operation of the inverter (2) is continued while suppressing the output current of the inverter (2) by the output suppressing section (212). In addition, a warning section (213) warns the user about the degradation in capacitor (24). With this arrangement, a solar power generation system capable of detecting a degradation in smoothing capacitor in the inverter (2) and appropriately operating the inverter (2) can be provided.

摘要： In a power supply system for converting the output of a DC power supply having an earth capacitance to AC power, an input voltage from an input-voltage detector and an intermediate voltage from an intermediate-voltage detector are input to an input-ripple controller. The latter calculates the difference between ripple voltages of the two voltages. The input-ripple controller adjusts the size of a ripple command value, which indicates the ripple current that is to be input to a converter circuit, so as to null the difference between the ripple voltages. Furthermore, using a ripple reference waveform having a DC level, the input-ripple controller generates a ripple current waveform so as to null the average value of a full-wave rectified waveform synchronized to the output of an inverter circuit, and outputs the generated ripple current waveform to an output calculator. The output calculator adds the DC current command from the input-voltage controller and the ripple current waveform from the input ripple controller to thereby generate an output current waveform, which is output to a converter circuit driver.

摘要： In a solar power generation apparatus using a solar battery having a relatively large ground capacitor and a power conditioner having a non-insulated input and output, a customer's ground fault interrupter may perform unwanted interruption due to a ground fault outside the customer's premises. To prevent this, when a ground fault is detected by a detector capable of detecting a ground fault within a shorter time than the customer's ground fault interrupter, the gate of inverter of the power conditioner is blocked, a switch is changed to an open state, and the input voltage of inverter is held at a voltage value higher than the peak value of the alternate current voltage of a power system until at least the switch changes to the open state.

摘要： Along with the expansion of the application range of solar power generation systems, connection to a single-phase 100-V system is required. To most easily meet this requirement, a non-insulated inverter with a single-phase two-wire 100-V output is used. It is preferable to use an inverter with a single-phase two-wire 200-V output, i.e., a most popular commercially available inverter. For this purpose, a power supplied from a solar battery is converted into a single-phase three-wire 200-V AC power form by the inverter. The output from the inverter with non-insulated inputs and outputs is supplied to a system through a transformer arranged to connect the line of the single-phase three-wire 200-V AC power to a single-phase two-wire 100-V system with one line grounded. To make a ground fault sensor incorporated in the inverter function, the median potential line of the single-phase three-wire 200-V AC power is connected to the ground line of the system.

摘要： When a ground fault occurs in some solar battery string, this solar battery string may be disconnected and operation of a solar power generation system may be continued. If the open-circuit voltage of the solar battery string is high, a safety problem arises. If the open-circuit voltage is decreased, the conversion efficiency decreases. Therefore, an intermediate switch is provided midway along the solar battery string. When a ground fault occurs, this solar battery string where the ground fault has occurred is divided into substrings.

摘要： The temperature of a bypass diode of a solar cell module is measured by a temperature detector from the exterior of the solar cell module, and the results of temperature detection of each bypass diode are mutually compared to detect the presence or absence of failure in the solar cell module. Also at least one solar cell in the solar cell module is covered with a light shielding plate, then a current flowing in the bypass diode bypassing to the covered solar cell is detected, and a failed solar cell module is detected from the result of the current detection. Also the solar cell module is provided with a temperature detector capable of detecting the temperature of the bypass diode and the temperature of an internal portion of the solar cell module other than the bypass diode. In this way, it is possible to detect a failure in the solar cell module easily and precisely, and also to detect short circuit failure in the solar cell.
