The invention discloses a QRNN-based reasonable range
estimation method for low-
voltage transformer area
line loss rate in the technical field of
line loss rates. The method aims to solve the technical problem that in the prior art, the
line loss rate evaluation basis cannot reflect the difference of a
transformer area in structure, power supply range and load level, and comprises the steps of collecting
transformer area operation data based on an existing power utilization
management system, and screening out transformer area line
loss rate influence factors;
correlation analysis is carried out on the line
loss rate of the transformer area, and line
loss rate key factors influencing the line loss rate are extracted; calculating a reasonable range of the line loss rate of the low-
voltage transformer area based on a neural network
quantile regression model; and according to the calculated reasonable range of the line loss rate of the specific transformer area, diagnosing whether the transformer area is an abnormal transformer area, and adjusting the transformer area.
Key factors influencing the line loss rate are extracted on the basis of actual operation data of an existing power utilization
information system, an existing marketing
system, an existing PMS
system and the like, the reasonable range of the line loss rate can be given for a specific transformer area, and a reliable basis is provided for diagnosing a transformer area with abnormal line loss.
