The invention relates to the technical field of power line communications, and provides a photovoltaic system monitoring method based on power line carrier communication. The method comprises the following steps: monitoring the running state of a plurality of photovoltaic modules, adjusting the output of the plurality of photovoltaic modules according to the running state of the plurality of photovoltaic modules, and improving the overall generating capacity of a photovoltaic system; storing running state information of the plurality of photovoltaic modules, diagnosing the running state information of the plurality of photovoltaic modules, and obtaining fault information; and performing remote control on the photovoltaic system according to the fault information, so as to control the on-off of the plurality of photovoltaic modules. The method can monitor the running state of each photovoltaic module, and timely and accurately find out which photovoltaic module has problems, so that the safety of the whole photovoltaic system is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of power line communication, in particular to a photovoltaic system monitoring method based on power line carrier communication. Background technique [0002] Power line communication technology appeared in the early 1920s. It is a means to use the existing low-voltage distribution network as a transmission medium to realize data transmission and information exchange. The existing communication monitoring system of the photovoltaic power station is relatively independent from the power transmission system, and additional communication lines need to be set up, which increases the cost. The existing technology can only monitor the operation of a string (20 pieces) of photovoltaic modules, but cannot monitor the operation status of each photovoltaic module. If the system fails, it can only locate the faulty string group, and cannot find out which one in a timely and accurate manner. There is a problem with th...
