ON-GRID SOLAR POWER GENERATION AND STREET LIGHTING SYSTEM CONTROL METHOD

摘要

PURPOSE: A method for controlling a grid connecting type sunlight generation and streetlight system is provided to allow the output of a solar cell module to access to commercial power after matching a phase and a voltage, thereby supplying stable power. CONSTITUTION: A distribution box(100) supplies a plurality of streetlight power sources. A main controller(101) generates an output control signal for turning on or off a streetlight by using the output of a timer(102) and a GPS module(103). A dimming controller(300) turns on or off an LED lamp(301) of the streetlight with goal illumination. A sensing unit(408) senses a voltage, a current and a zero crossing signal of a streetlight power line(104). A microcontroller(400) controls a boosting circuit(401). The microcontroller controls a radio wave rectification output unit(402). A PLC module(200) transmits control data and operation state data to the streetlight power line.
