Method for analyzing influence of photovoltaic access on electric energy quality and related device

The invention discloses a method and related device for analyzing the influence of photovoltaic access on electric energy quality, and the method comprises the steps: firstly, carrying out the correlation interaction of marketing database information, metering database information and production database information at regular intervals, thereby achieving the data synchronization; screening photovoltaic users with unqualified voltage quality caused by photovoltaic access, photovoltaic users with unqualified power factors caused by photovoltaic access and photovoltaic users with unbalanced distribution transformer three phases caused by photovoltaic access from the meter code information; and finally, according to the photovoltaic users, generating a report and a list indicating that the public power distribution and transformation electric energy quality is disqualified due to distributed access. Compared with the prior art, multi-dimensional analysis of voltage quality disqualification, power factor disquali
