Reactive daily curve bad data recognition and correction method

The invention provides a reactive daily curve bad data recognition and correction method. The method can be applied to reactive power bad data recognition and correction of a power grid; the data can be used as important basis for formulating an operating way of an electric power system; by performing recognition and correction on reactive power historical data, the reactive power of the power grid can be predicted accurately, energy-saving dispatching working efficiency can be improved, calculation precision of day-ahead power generation can be remarkably improved, and safety and accuracy of a power generation plan can be effectively ensured; and therefore, the reactive daily curve bad data recognition and correction method is of great practical significance and high application prospect.
