The invention discloses a
transformer area switch physical
topology identification method based on
power grid total
data acquisition. The method comprises the following steps: step 1,
data acquisition; step 2, data initialization: taking an electric quantity curve as data generated by
initial topology; step 3,
data sorting; step 4, grouping of direct connection branches; step 5,
branch topology generation and
verification; step 6, determination of a superior-subordinate relationship of the direct connection points; and step 7, re-
verification of the physical topological relation. Compared with a scheme of generating a disturbance
signal and a scheme of adopting a low-
current pulse signal in the market, the identification method has the following advantages: the
power consumption is low, and the risk of equipment burning caused by untimely heat dissipation is avoided; data carried by the equipment is adopted for analysis, and the scheme cost is low; no
harmonic wave is injected into the
power grid, no interference is generated on equipment of the
power grid, timing starting is not needed, and efficiency is high.
