Multi-tense full-path topology analysis system and method

The invention discloses a multi-tense full-path topology analysis system and a multi-tense full-path topology analysis method. The multi-tense full-path topology analysis system comprises: a storage module pre-stores historical switch states and historical power consumption data on each physical node associated with historical moments; the analysis module analyzes the historical power consumption data on each physical node to obtain historical topological data; the topology construction module constructs a topology model according to the historical topology data, and the topology model generates a historical topology network according to the historical topology data; the optimization module adjusts each historical switch state in the historical topology network to obtain simulated historical power consumption data, and calculates each simulated historical power consumption data and real historical power consumption data at the next moment to obtain a total historical deviation value; and an improved simulated
