Abstract
The invention discloses a flexible drive system for grid data evaluation. The flexible drive system for the grid data evaluation includes a manual drive mode and an automatic drive mode, wherein the automatic drive mode comprises a timing drive mode and an event drive mode, and the above modes are integrated together to form a flexible drive mode. The grid data evaluation mainly includes four function modules: a switch estimation, a topology estimation, a state estimation and a parameter estimation. The manual mode is operated by a user manually through a terminal to trigger a data evaluation function module, i.e. the user determines start and stop of data evaluation; the timing drive mode periodically triggers the data evaluation function module when time of a timer clock is up; therefore, the start and stop of the data evaluation are periodic, and a period can be adjusted; the event drive model employs an occurrence of an event to trigger the data evaluation function module; this event is generally a change of data or a start of a functional module in a grid, and at the moment, the start and stop of the data evaluation is random to an extent.
