The invention discloses a multi-adaptive black-start apparatus. The apparatus supports IEC61850,
MODBUS, 104, and IEC61970 communication protocols, and solves the problem that systems under different protocols among different power plants in
black start cannot be interconnected. The apparatus comprises a main control board, a communication board, an AD board, an input board, an output board and a man-
machine interface. Under a normal condition,
power grid data is read from an
SCADA system; when a power
plant system is in failure, the apparatus obtains the
power grid data from the AD board; the output board controls the
relay, so that the problem of black-start failure caused by other
system faults is solved; the main control board is the logic
processing center; the communication board is the core of the apparatus and
external communication; the AD board is the hardware core for obtaining the
power grid data of the system; the input board monitors the opening / closing states of the
relay; the output board controls the opening / closing states of the
relay; by adoption of the apparatus, the self-starting of the power
plant under a condition of being disconnected from the power grid can be realized; and in addition, the apparatus can adapt multiple communication protocols and multiple onsite conditions, so that the economical efficiency, rapidness and stability of the power
plant black start are improved.
