The invention provides a voltage stability monitoring method. The voltage stability monitoring method comprises the following steps: collecting the voltage of each to-be-monitored circuit regularly; judging whether the acquired voltages meet the corresponding voltage threshold ranges or not in real time; for each voltage which is judged not to meet the corresponding voltage threshold range, performing voltage instability alarm on the corresponding to-be-monitored circuit, and storing the voltage instability alarm and the circuit identification number of the corresponding to-be-monitored circuit into a first database; for each voltage which is judged to meet the corresponding voltage threshold range, storing the circuit identification number of the voltage and the circuit identification number of the corresponding to-be-monitored circuit in a second database; and periodically uploading the data stored in the first database and the second database to a remote monitoring platform, and emptying the first database
