CONTROL METHOD OF SPURIOUS TRIP OF SECTIONAL BUS SWITCH AT OPERATION OF ANNULAR NETWORK IN SUBSTATION STANDBY MODE

摘要

FIELD: electricity.SUBSTANCE: method consist in fixation of current surges and in measurement of time between them. Available voltage on buses and available current in the main power source line is controlled, and if voltage on buses and current in the main source line disappears, and voltage on buses of a standby power source does not disappear, a conclusion is made on spurious trip of a sectional switch of buses of a two-transformer substation.EFFECT: enlarging functional capabilities.2 dwg
