The invention discloses a quick query method used for power big data. The method is characterized by specifically comprising the following steps of SS1, establishing a stereoscopic index system for the power big data by utilizing a dynamic index map technology; SS2, creating indexes by utilizing a multi-conditional combination query method; and SS3, establishing a quick combination query scheme for the power big data. The method has the beneficial effects that establishment and quick combination query of multi-conditional column indexes are realized by adopting the dynamic index map technology; and a composite index is specially created for each query by establishing an index map, so that a full table is prevented from being scanned line by line and the combination query speed of the power big data is greatly increased.
