A
system for reducing
tripping frequency of a power distribution line comprises a province dispatching data-side sub-
system, a
power grid operation and maintenance sub-
system and a
fiber transmissionline, wherein the
fiber transmission line is used for connecting the province dispatching data-side sub-system and a
power grid operation and maintenance sub-system, the province dispatching data-sidesub-system comprises a province dispatching data network, an acquisition
server, a first data
server, a first switchboard and a first photoelectric converter, the
power grid operation and maintenancesub-system comprises a second photoelectric converter, an entity fireproof wall, a communication
server, a second data server, a second switchboard and a working
station, and an output end of the first photoelectric converter is connected with an input end of the second photoelectric converter via the
fiber transmission line. A reliable and safe fault
information control platform is formed by fully utilizing an existing network passage of a province power company and fault information of a province
database; and by the system, the functions of fault information classified counting, comparisonanalysis, fault positioning, protection configuration setting and operation and maintenance suggestion can be provided according to fault
tripping information and fault
processing information.
