(1) INTEL industry specific microprocessor, imported PLC and 2 controls with 32 bits compose to the embedded double microcomputer excitation system. Two sets of microcomputer work on-line as hot reserve each other. If the one goes wrong, the system transmits to the other one automatically without any interruption. The interval is less than 200us.
(2) Add analog channel in support. Analog channel separates from main control channel, adjust by the way of excitation current closed-loop control. It shall be run into operation，when there're something wrong with main control channel.
(3) Have the whole model of voltage control, current control, reactive control and power factor control, which can satisfy various operation mode demands with different power stations.
Voltage control: maintain invariableness of terminal voltage
Current control: maintain invariableness of excitation current
Reactive control: feedback reactive power and invariable reactive operation
Power factor control: maintain invariableness of power factor
(4) Apply to several complicated control ways, which have excitation system performance reach the excellence
PID (Proportional, Integral, Differential)
PSS (Power System Stabilizer)
LOEC (Linear Optimal Excitation Control)
NOEC (Nonlinear Optimal Excitation Control)
(5) Provide intact output interface, in order to connect with all control equipments in power station.
Routine interface: provide standard output and input interface as power system rule.
Communication interface: including communicates ways of RS232 and RS485. It can communicate with intelligent devices of intergraded automation of power station directly.
(6) Interactive operation interface ( fool type) and intuitionistic HMI
