.REMOTE MONITORING SYSTEM FOR SOLAR CELL PROBLEM

摘要

The present invention relates to a fault diagnosis remote monitoring monitoring system for a solar panel The present invention relates to a connecting panel for a solar cell power generating apparatus, and more particularly, to a connecting panel for a photovoltaic power generating apparatus in which heat generation of a diode is minimized, A monitoring system capable of remotely detecting and monitoring a failure state of the corresponding small group, To a connecting board for a photovoltaic power generation apparatus in which heat generation of a diode is minimized to improve efficiency The composition is as follows Solar panel modules connected in series are divided into at least two solar panel subgroups. The instantaneous power is measured to measure the instantaneous power, and the instantaneous solar radiation amount is measured by providing a solar radiation amount measuring device at a close proximity of a small group to be a solar radiation reference value, and the measured instantaneous power value between the subgroups of the respective solar battery plates A microprocessor for judging an unbalanced state by comparing the measured instantaneous irradiance reference value with the measured instantaneous power value of the individual solar panel subgroup and judging the operation state and deterioration of the solar panel module of the corresponding solar panel subgroup, And communication means for transmitting the determination of the operating state and deterioration state of the small battery group and the data to the mobile communication terminal of the remote location user 4, a plurality of solar panels S1, a plurality of input terminals S2, a plurality of fuses S3, and a breaker (hereinafter referred to as a breaker , A plurality of diodes S4 and an output terminal S5 for collecting power output from the plurality of diodes into one, A plurality of bypass circuits (100) for bypassing the power input from the plurality of fuses (S3) to the plurality of diodes (S4) and outputting the power to one output terminal (S5) The plurality of bypass circuits (100) are opened and closed in accordance with a control signal of the controller (130) A plurality of detour switches 110, A measurement unit 120 connected to the measurement unit 12 to determine the state of the circuit 200 and to control the opening and closing of the bypass switch 110, Let's When a plurality of bypass switches 110 for opening and closing the plurality of bypass circuits 100 are turned on If abnormally low power is generated in any one of the groups in the course of normally generating power equally in each of the plurality of groups, the circuit 200 is measured through the measurement unit 120 When the measured value deviates from the preset voltage (power) range, it is judged that a reverse current flows in the circuit direction in which the high power normally produced flows abnormally The reverse current is cut off by the diode by turning off the bypass switch 110 connected to the low-power circuit 200 and when the measured power value through the measuring unit 120 during the monitoring is within a preset voltage range , It is determined that the power generation is normal and the bypass switch 110 is turned on to output power to the output terminal S5 via the bypass circuit 100.
