Turbine and machinery control systems govern speed, load, protection, and sequencing for rotating equipment such as steam and gas turbines, compressors, and large drives. The architecture typically combines dedicated control processors, I/O and signal conditioning, overspeed and protection modules, trip solenoids or relays, and supervisory interfaces communicating to plant control networks. Technical characteristics emphasize fast response, high-integrity protection paths, redundancy where required, vibration and condition inputs, and robust diagnostics to support safe operation. Functional capability includes startup and shutdown sequences, governor control, load sharing, permissives and interlocks, trip logic, and integration to DCS or SCADA displays.
