Core Functions of Excitation System (Dedicated to Power Generation Applications)
Specifically designed for excitation and voltage regulation of steam turbine generators and hydroelectric generator sets, replacing traditional excitation regulator hardware:

– Terminal voltage closed-loop control
Real-time acquisition of generator PT voltage and CT current; rapid adjustment of excitation current via PID + Power System Stabilizer (PSS) algorithms to maintain constant generator output voltage and resist grid disturbances and load fluctuations.

– Built-in complete excitation protection logic
Includes over-excitation limit, under-excitation limit, reactive power limit, V/Hz limit, loss-of-field protection, overcurrent protection, and load rejection overvoltage suppression—providing a comprehensive protection system against generator excitation faults.

– Reactive power / power factor control
Supports fixed reactive power or fixed power factor operation to meet grid interconnection dispatch requirements.

– Dual-channel redundancy compatibility
Supports dual-controller redundant hot standby configuration in the excitation system, enabling seamless failover with no interruption, meeting SIL3 safety level requirements for power stations.
