High-voltage parallelly-connected capacitor complete equipment state evaluation method based on power detection

The invention provides a high-voltage parallelly-connected capacitor complete equipment state evaluation method based on power detection, and belongs to the technical field of monitoring of transformer device states. The method is characterized by comprising following steps of step 1001, starting; step 1002, obtaining bus voltage; step 1003, obtaining operation voltage of a reactor; step 1004, obtaining operation voltage of an electric power capacitor; step 1005, obtaining and decomposing current signals; step 1006, obtaining power parameters; step 1007, judging whether to be in the normal state; step 1008, continuing to operate; step 1009, judging whether to be in a noticing state; step 1010, judging whether to be in an abnormal state; step 1011, giving out a sound-light alarm; and step 1012, giving out a tripping instruction. By detecting the power parameters of states of high-voltage parallelly-connected capacitor complete equipment in operation, disadvantages of the requirement of power-off detection and
