The invention discloses a power quality overall monitoring system at coastal areas and areas with high peak-valley difference. The system includes an adjustable transformer, a relay A, a relay B, a power supply module, a reference voltage module, an undervoltage detection module, an overvoltage detection module, an undervoltage protection module, an overvoltage protection module and a switch source; the input end of the adjustable transformer is connected to an alternating current input module; and the output end of the adjustable transformer is connected to the power supply module. The systemcan automatically adjust the winding number of the transformer according to the voltage fluctuation of commercial power, so that effects of stably outputting voltage can be achieved, the purpose of performing overvoltage and undervoltage protection on a circuit can be realized, the supply voltage of electric loads can be stable, and thus, the circuit has the advantages of being simple in structure, stable in output and various in function.
