PHOTOVOLTAIC SYSTEM ASSOCIATED WITH POWER LINE AND CONTROL METHOD THEREOF

摘要

A solar light generating system is provided to construct a solar light generating system having a kW value at low cost by remarkably increasing kW value even if the rated capacity of a solar cell module is lowered. A plurality of solar cell arrangements are constructed in a solar cell module(110). A DC/DC converter(120) boosts DC power outputted from the solar cell module. A power adjust module(130) charges DC power outputted from the DC/DC converter. A DC/AC converter(140) converts the DC power outputted from the DC/DC converter or the power adjust module into AC power and supplies the converted AC power to a system. A control module(150) stores data with respect to a time interval of predetermined peak power consumption, controlling each construction. The control module charges the power adjust module with the DC power outputted from the DC/DC converter except at a time interval of predetermined peak power consumption and discharges the DC power charged in the power adjust module to the system through the DC/AC converter. The control module can include a DC/DC converter module control part for generating a first PWM control signal for controlling the DC/DC converter, a power adjust module control part for controlling the charge/discharge function of the power adjust module, a DC/AC converter module control part for generating a second PWM control signal for controlling the DC/AC converter, and a control data storage part for storing control-related data including data with respect to the time interval of the peak power consumption.
