Abstract
The invention provides a multi-module active electric power filter system and method of transmitting the loading information of the same, with which the active electric power filter modules on different load paths can operate individually, and an information transmission method is employed to achieve a parallel processing means of making the active electric power filters on different load paths compensate for each other, so as to eliminate the drawback of only compensating a single load path set in the conventional skill, increase the system utilization rate, and decrease the influence between load paths. Further, in the invention, the signal communication among all the active electric power filters on the same electric power network is performed with a communicating means that does not require for additional connection signal wire. Therefore, it is able to avoid connecting control wires among the active electric power filters, which causes the problem of having additional wiring and cost of wiring.
