Problems solved by technology
[0003] However, the current method of identifying whether a three-phase three-wire meter has a voltage loss fault will be interfered by factors such as load and data transmission quality. There are a large number of errors or useless measurement data in the collected measurement data, which may easily cause the monitoring platform to fail Misjudgment of three-phase three-wire meter equipment, resulting in failure to repair three-phase three-wire meter equipment in time, resulting in losses for power companies or users

The application relates to an under-voltage fault monitoring method and apparatus based on a three-phase three-wire meter device. The method comprises the following steps that: various metering data re obtained; abnormal metering data are filtered from the metering data; initial under-voltage determination is carried out on the filtered metering data; when the initial under-voltage determination results indicates an under-voltage state, a maximum current value of a primary side of an under-voltage phase is obtained; when the maximum current value of the primary side of the under-voltage phaseis greater than a first value, a secondary side voltage of the under-voltage phase within preset time is obtained; and when the secondary side voltages of the under-voltage phase are lower than a second value within the preset time, under-voltage fault occurrence at a three-phase three-wire meter device is determined. With the method provided by the invention, the accuracy of identification of theunder-voltage fault at a three-phase three-wire meter device is improved effectively.
Description
technical field [0001] The present application relates to the technical field of power system monitoring, in particular to a method, device, computer equipment and storage medium for monitoring a voltage loss fault based on three-phase three-wire meter equipment. Background technique [0002] In the process of power system monitoring, three-phase three-wire meter equipment can provide a large amount of metering data for three-phase three-wire circuit monitoring, and provide data support for the monitoring process. Therefore, the normal operation of three-phase three-wire meter equipment is particularly important. When the three-phase three-wire meter equipment has a voltage loss fault, it is necessary to quickly determine which three-phase three-wire meter equipment has a voltage loss fault, so that the three-phase three-wire meter equipment can be repaired in time to ensure normal operation. [0003] However, the current method of identifying whether a three-phase three-wi...
