Features
SCAUT comprises different features which optimize your compressor train performance:
Compressor Control
- Anti-surge control designed to cover even the most complex tasks such as variable molecular weight, fast closing discharge valves or increasing suction temperature during recycling
- Performance control acting on mass flow, suction- or discharge-pressure including limiting functions such as discharge pressure or motor-current
- Load-sharing controller for parallel trains
Integrated Steam Turbine Control
- Speed governors integrated into the SIMATIC S7 PLCe
- Safeguarding functions, such as excessive temperature or minimum flow protection
- Additional control of e.g. extraction pressure or inlet pressure
- Automatic ramp-up to minimum governor speed according to predefined start-up curves including the avoidance of up to two critical speed bands
Flexible Modular Redundancy
As sensors and actuators are the weakest parts of an instrument loop, any redundancy concept should start with the appropriate number of field devices. (Typical fault rate split for a loop (according to TÜV): Sensor 35% - PLC 15% - Actuator 50%)The Siemens SCAUT system is designed to match the PLC and field device redundancy in order to:
- Minimize costs
- Maximize availability
Safety-integrated system
Up to SIL3 certified loops according to IEC 61508 for safety-related functions
