Generator Products 4-Pole Synchronous Gas and Steam Turbine Applications Our range of 4-pole generators provide a reliable product which is based on a modular construction concept utilizing the latest design and manufacturing techniques. All generators include Vacuum Pressure Impregnation (VPI) insulation systems (for both the stator and rotor components) and a unique vent stator technology for maximum heat dissipation. Stators are either mounted in a box-frame with end-shield mounted bearings or in a base frame with pedestal bearings. Up to 20 MW a laminated rotor is used. Above 20 MW...

Generator Products Reciprocating Engine Driven (Delta) Diesel and Gas Reciprocating Engine Applications Wind Turbine Applications This design has the stator mounted into a base-frame with pedestal bearings to support the rotor. These are used in many applications from Prime and Emergency Power to Marine Power. Although these machines employ the same insulation systems as other generators, they tend to be more specifically designed for the application or project. The speed can range from 17 to 1800 RPM depending on the generator type required. The speed range for these machines is very wide....

Rotors Laminated Pole Laminated cruciform assembly Wire-on-Edge field windings Coils wound directly on poles Cooling vee-block designs Advanced ventilation and fan designs This rotor has a laminated cruciform assembly and a wire-on-edge field winding. Each pole face has a set of damper bars brazed to a copper segment at each end, and coil support bars to prevent the ends of the coils from moving in service. After winding and vacuum pressure impregnation treatment, the rotor assembly is shrunk on to the shaft to ensure a positive fit. The heating process is computer controlled with a number of...

Rotors Integral Tip Solid Pole The pole tips or shoes on this rotor are machined from the single rotor forging. All other features are the same as the bolted tip rotor. Solid poles hold a strip-on-edge field winding. These types of rotors are used in special 60 Hz applications or otherwise specified by customers requiring maximum durability. Cylindrical Wound This rotor is used in applications where a distributed winding is required. The rotor body is made from laminations with slots to take the windings. The windings are placed into slot-liners when inserted and wedged in at the surface,...

Stators Two Layer Lap Winding Low-loss lamination grade No core-pack welding Individual slot wedging Thermal vent technology Global VPI with rotate cure The stator core assembly consists of varnished laminations of cold-rolled low-loss silicon steel, clamped between compression plates. The laminations are supplied in the finally annealed condition, and are insulated to reduce eddy current losses. The core is built around a central mandrel, to enhance the bore profile. There are radial ventilation ducts at intervals along the core length, formed by spacers welded to laminations, with similar...

Vacuum Pressure Impregnation (VPI) Void free insulation is vital for the life of medium and high voltage insulation systems. The stator is heated in an oven to dry out any moisture. Then it is placed into a pressure vessel where the lid is vacuum sealed. Then resin, at varying temperature, is pumped into the chamber to fill all voids on the stator. After a period of time, dry air is pumped into the top of the vessel creating a “pressure blanket” over the resin, “pushing” it into all remaining voids. The pressure is then released and the stator is placed in an oven for the resin to cure. The...

Analysis Tools Finite Element Modern analysis tools such as finite elements make predictions regarding performance more accurate. Before integrating the generator with an engine, we calculate all the natural frequencies of the machine in order to avoid exciting them. Through a particularly advanced mathematical simulation we can calculate the effects of an explosion in a terminal box due to an electrical fault. This allows us to optimize the integrity of the terminal box during a very rare fault condition. Fluid Dynamics We analyze our generator designs to improve their ability to not run...

Training & Service Generator Controls Global Service Capability The GEPC RVD Mk III system uses a Programmable Logic Controller (PLC) to perform all the control functions and fire a power stack for the excitation. These are generally part of a “turnkey” type system where many other controls functions are being supplied by GE. These systems are most common in large, utility-type generators. GE’s full global service network delivers fast initial response and follow-up on all warranty and service issues including: Controls Training GE can supply comprehensive training in controlling generators...
