1. A system for tracing harmonic sources based on cloud-edge-terminal collaboration, comprising:
a terminal module, being configured to collect real-time harmonic data for reflecting an actual operation situation of a power grid and transmit the collected real-time harmonic data to an edge module;
the edge module, being configured to comprise a plurality of edge computing servers of edge cloud, wherein the plurality of the edge computing servers are deployed for transformer substations and transformer districts by units, realize a hierarchical control between the plurality of the edge computing servers according to voltage levels, and transmit a tracing task of harmonic sources through hierarchical interactions between the plurality of the edge computing servers; wherein, one of the plurality of the edge computing servers receiving a request of tracing service of harmonic sources performs the tracing task of harmonic sources, and feed a tracing result of harmonic sources back to a central module; and
the central module, being configured to comprise a cloud server for controlling the system for tracing harmonic sources, wherein the cloud server receives the request of tracing service of harmonic sources initiated by a user of the system, determines one of the plurality of the edge computing servers offloaded by the request of tracing service of harmonic sources, stores a final tracing result from entire the system for tracing harmonic sources, and matches a typical harmonic source according to a disturbance source information.
