2.1.1.1 General
This turbine is a single flow extraction condensing type. Steam initially enters the steam inlet flange near the end of the high-pressure section and flows through the turbine stages toward the generator end of the unit. After passing through the turbine stages, the steam is exhausted to condenser. The exhaust hood is keyed to the foundation plates at a point near its center of the exhaust hood to prevent axial motion. The turbine expands axially from this point. The front standard is free to slide axially but the standard and hood are guided to prevent transverse movement.
2.1.1.11 Control Valve (CV) of Main Steam
Steam, after passing through the MSV, is admitted through the CV to the high-pressure turbine. CV controls the amount of steam passing to the turbine. It is opened and closed by actuator and is controlled by Digital Electro-Hydraulic Control (D-EHC) system through turbine hydraulic system.
2.1.2 Technical Specification of Steam Turbine & Aux
Type: Single Casing Single Flow impulse type condensing turbine Rated Output: 188,000 kW at Generator terminal
Speed: 3,000 rpm
Rotation: CCW (Viewed from front of Turbine) Last Stage Bucket Active Length: 42" (Nominal) Allowable Cycle Change: 48,5 - 50,5 Hz
2.1.5.1 Condensate System
Type: Horizontal Surface Cooling, with divided waterbox, Two-Pass Type
2.2.1.1 Generator General
The generator consists of the stator, rotor, cover, bearing, air-to-water cooler. The stationary armature is attached to and supported by generator base. The rotor is supported by the bearings. Air-to-water coolers are mounted above the stator. The cooling system is competely enclosed to prevent entrance of dust and moisture.

2.2.1.2 Extraction System
The brushless generating system consists of main generator, rotating AC Exciter, Rotating Rectifier (R-RF), Direct Coupled PMG (Permanent Magnetic Generator) and AVR (Automatic Voltage Regulator). Main components of hte AVR are the digital automatic controller, AVR Amplifier, three phase thyristor rectifier and U-ISO Isolation Unit.
