Residential household meter voltage misalignment monitoring method for HPLC transformer area

The invention discloses a residental household meter voltage misalignment monitoring method for an HPLC transformer area. The method comprises the following steps: acquiring power supply data of a transformer area to be monitored; selecting a calculation time point of the transformer area general table; calculating a reference voltage value of each phase of the transformer area to be monitored; calculating the voltage range of each phase of the transformer area to be monitored; and determining the voltage misalignment state of each residential meter in the transformer area to be monitored. According to the residential household meter voltage misalignment monitoring method for the HPLC transformer area, data can be conveniently collected through HPLC communication in the transformer area adopting HPLC communication, on-site verification is not needed, whether residential household meter voltage measurement is misaligned or not can be judged only by analyzing and collecting background data of a system, and the
