| Summary: | For increase of efficiency protection of busbar 110-220 kV is proposed to use an algorithms, based on the differential principle, in combination with the method of double entry. Double entry it is method of registration of economic operations accounting, by which every change of the state funds recorded in two accounts, ensuring the overall balance. By providing redundant processing of information about currents measured at the ends of the protected object, and is formed in a special matrix that implements the reliable operation of the differential protection, eliminating its excessive action when damaged the current transformers. |
