1 ICS-GT INTEGRATED CONTROL SYSTEM FOR GAS TURBINE

2 ICS Gas Turbine Complete Control ICS-GT control system is an plc-based, integrated solution for gas turbine control and protection. The ICS-GT control system setup ranges from one to three sections according to the complexity of system. The choice of the right setup is performed during the very first steps of the proposal simply filling up a form. The presence of ancillary subsystems such as Fire&Gas or vibration monitor racks is contemplated as well. Control Panel Set up Three macro setup can be configured: Core: one section performing the gas turbine control and protection; Aux: two sections, Core plus a section dedicated to auxiliaries controls, centrifugal compressor control or generator synchronization; Plant: three sections, Aux plus a section dedicated to plant controls; Core configuration A single 800mm width section is dedicated to the Turbine control core. The Turbine section contains: One PLC rack for the Simplex Configuration, ore Two CPU racks for the Duplex Configuration; All the I/O cards are directly on the rack in order to maximize the signals update; Redundant power supplier for the 24 Vdc; Front keypad for the system configuration; Relay, fuses, switches, horn; Description The control system can be configured as Simplex Or Duplex. Simplex means a single CPU governing the system, duplex means two CPUs: one actually controlling the system (Master), the other one ready to replace the Master on the fly in case of fault (Slave). The Duplex configuration increase the availability of the system: when one CPU is not available (for any reason, for example during a SW upgrade) the other one carries the system.

3 Intrinsically Safe barriers for those signal of the control core classified as EEx-I The control panel provides a keypad mounted in the front door to display and to set the configuration parameters and to monitor the main signals. Aux configuration A 800mm width section is placed next to the above described Core configuration base section. This section is present in case of: Auxiliary systems such as lube oil pumps, fan cooler, acoustic enclosure fans, emergency lube oil pump, the crank system; Anti surge, load sharing, performance control in case of mechanical drive gas turbine; Synchronization in case of generator drive gas turbine; Fire & Gas system; Vibration Monitor System; Over speed protection; Additional sections can be added in order to fulfill customer s requirements. Plant configuration A 800mm width section is placed next to the above described Aux configuration. This section is present in case of: Plant control loops, such as a co-generation plant; The control panel provides a keypad mounted in the front door to display and to set the configuration parameters and to monitor the main signals.
