DISTRIBUTED POWER SOURCE SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a distributed power source system capable of making a power generation device appropriately operate.SOLUTION: A distributed power source system comprises: a power generation device 20 including a power generation control unit 23 and a waveform analysis unit 24; and a charge/discharge device 10 including a charge/discharge control unit 13. The power generation control unit 23 is configured so as to perform protection control on the basis of a result of analysis by the waveform analysis unit 24. The charge/discharge control unit 13 is configured so as to perform signal supply control of making a signal supply unit SP supply, by using a signal power waveform differing from a reference power waveform of power supplied from a power system 1, a state signal showing an operation state of the charge/discharge device 10 itself to an AC line 2. The waveform analysis unit 24 analyzes a power waveform on the AC line 2 to acquire the state signal as a signal power waveform supplied to the AC line 2 by signal supply control performed by the charge/discharge control unit 13 of the charge/discharge device 10. The power generation control unit 23 determines the operation state of the charge/discharge device 10 on the basis of the state signal acquired by the waveform analysis unit 24.
