The invention discloses an intelligent research and judgment and power
recovery method and
system based on a low-
voltage power distribution network, and relates to the technical field of intelligent
power grid and
power system automation, and the method comprises the steps: collecting
monitoring data, carrying out
information fusion check based on geography and
power management, dynamically generating a topological file, and constructing a hierarchical visual
power grid model. Analyzing the states of a
circuit breaker and protection equipment, calculating main and
backup protection deviation, analyzing electrical quantity change in combination with
wavelet transform and
singular value decomposition, and identifying a fault section; a whole-network
sensing system is constructed, three-
phase imbalance and zero-sequence current are monitored in real time, and rapid power restoration and active research and judgment are carried out by combining a dichotomy and an intelligent switch optimization power restoration strategy. According to the intelligent research and judgment and power
recovery method based on the low-
voltage power distribution network, the reliability and safety of the power distribution network are improved by constructing an environment
monitoring system, the accuracy of
fault analysis of a low-
voltage transformer area is improved through topology accurate checking and intelligent fusion, and the
fault analysis accuracy of the low-voltage
transformer area is improved through a dichotomy fault isolation and intelligent power
recovery strategy. The fault recovery efficiency is improved, and better effects are achieved in the aspects of safety, accuracy and efficiency.
