SOLAR PHOTOVOLTAIC POWER GENERATION SYSTEM EQUIPPED WITH NATURAL DISASTER DETECTION AND POWER SUPPLY PATH BLOCKING FUNCTION

摘要

Disclosed is a photovoltaic system with functions for detecting an outbreak of natural disasters and blocking a supply path of generated electricity. According to the present invention, the photovoltaic system comprises: a photovoltaic apparatus including a solar cell module, a support structure supporting the solar cell module, and a first vibration sensor installed in at least one of the solar cell module and the support structure; a connection panel receiving and transferring generated electricity outputted from the solar cell module to an electricity conversion apparatus and including a second vibration sensor and a blocking switch blocking the supply path of the generated electricity; and a control unit using vibration information detected in the first and second vibration sensors to control the blocking switch to be turned on and off. Moreover, the control unit detects a case that vibration is simultaneously generated in the first and second vibration sensors which are spaced apart each other to detect an outbreak of natural disasters, and generates a control signal for changing the blocking switch into an on-state when the first and second vibration sensors detect vibration exceeding a first reference magnitude.
