Performance by design


Design standardsThe electrical design is based on the relevantIEC or NEMA standards and mechanical designon the relevant ISO standards. In marine oroffshore applications the additional designcriteria of the applicable classification societyare followed. These societies include ABS,BV, CCS, CR, DNV, GL, KR, LR, NK, RINA,and RS.

EfficiencyOur generators are designed for highefficiency, with losses minimized throughthe effective use of materials, state-of-the-artinsulation and optimization of rotors, statorsand fan designs. This benefits users like powerplant operators as high efficiency helps tosave money, cuts operating costs and meansmore electricity for the same investment.

Vibration toleranceGenerators coupled to reciprocating enginesare always exposed to engine inducedvibration, especially when the generator andengine are built on a common base frame.We use sophisticated design tools to analyzethe impacts of external torsional and linearvibrations on the generator. This work is

based on information from engine or generatorset builders about the natural frequencies or globalvibration modes – like base frame horizontal andvertical bending or torsion along the longitudinalaxis – to help ensure troublefree operation.The generators withstand linear vibration up tothe limits specified in the relevant ISO standard(typically 10 - 20 mm/s), which significantly exceedsthe vibration originating from the generator itself(max 2.8 mm/s during final testing).

Recommended protectionsThe generators are built to withstand abnormalsituations such as unbalanced load, overcurrent oroverload in accordance with the relevant IEC orNEMA standards. However, in order to avoiddamage to the generator in situations where thepermissible values are exceeded, the followingprotections are recommended:� Thermal overload in stator winding

� Network short-circuit

� Stator interwinding short-circuit

� Stator earth fault

� Overvoltage

� Unbalance load or shorted turns in same phase

� Underexcitation or loss of synchronism

� Undervoltage and intermittent loss of voltage

� Monitoring of temperature detectors

Modular construction

Modular design combined with a highdegree of standardization means shortermanufacturing times. This benefitscustomers in terms of faster lead times.

MountingAll our synchronous generators are designedfor horizontal mounting. They are supplied asintegral units, even up to the highest sizes andoutputs. They therefore require no furtherassembly on site, which means that installationtimes are substantially reduced.

The most common mounting arrangements are:IM code Description

IM1001 - two end-shield bearings, cylindrical shaftend, feet down

IM1101 - two end-shield bearings, cylindrical shaftend, raised feet

IM1205 - one end-shield bearing, flanged shaftend, feet down

IM1305 - one end-shield bearing, flanged shaftend, raised feet

IM2001 - two end-shield bearings, cylindrical shaft,flange at D-end

IM7201 - two pedestal bearings, cylindrical shaftend, feet down

IM7301 - two pedestal bearings, cylindrical shaftend, raised feet


Frame constructionThe smaller generators feature a three partmodular frame consisting of the stator housingand two end housings. The end housings areprecision machined and finally bolted or weldedto the stator housing, ensuring perfect alignmentand sufficient rigidity to withstand engineinduced vibrations. End-shield type bearingsare mounted on the end housings. The largergenerators are built in a self-supporting full frameand equipped with integral pedestal bearings.

Corrosion protectionOur generators are designed and built towithstand the applicable environmentalconditions. Screws, washers, all surfaces madeof steel, aluminum alloy, cast iron and allinsulation materials are treated in accordancewith the chosen paint system. Selection of asuitable paint system gives reliable anti-corrosionprotection even under the most severeenvironmental conditions. For moderate indoorconditions the standard finish is a two-packepoxy paint that is moisture-proof in accordancewith the relevant standards. Solvent freepaints are used wherever possible in orderto minimize environmental impacts.

ABB's R&D engineers work

closely with engine manufacturers,

using FEM and dynamic animation

techniques to determine various

vibration models, test critical

parts and verify that hazardous

mechanical resonances do not

occur in the generator.

Cooling and protection

There are three commonly used cooling arrangements:open air, air-to-water and air-to-air.


Open air coolingOpen air cooling can be used where theair in the immediate environment is relativelyclean and there is adequate air circulation.The cooling air is typically drawn in throughair filters, passed through the active parts ofthe generator, and then exhausted back to theenvironment. If the engine room ventilationsystem cannot compensate for the temperaturegradient caused by the hot air, the generatorair outlet can also be ducted to allow the airto be exhausted outdoors. Open air coolingis the most typical solution for stationaryindoor power plants.

Air-to-water closed circuit coolingThe cooling air circulates in a closed circuitthrough the active parts of the generator andthen through an air-to-water heat exchanger.This configuration passes hardly any heat tothe surrounding environment, and representsan ideal solution for situations where closedcircuit cooling is required due to installationoutdoors, installation in a hazardous area, orwhenever the quality of the surrounding air isnot otherwise suitable for direct cooling.It is also ideal for installations in engine roomswith limited ventilation, such as ships.

Air-to-air closed circuit coolingThe cooling air circulates in a closed circuitthrough the active parts of the generatorand through an air-to-air heat exchanger.This solution is generally used in situationswhere a closed circuit cooling system– such as air-to-water cooling – is requiredbut water is not readily available. This coolingarrangement requires an additional shaftmounted or electric fan to ensure sufficientair flow through the cooler.

ProtectionThe enclosures feature protection inclasses IP21, IP22, IP23, (drip proof),or IP44, IP54, IP55 and IP56 (totally enclosed),or equivalent NEMA protection classes.Generators are also available for hazardousareas in accordance with IEC/ATEX orNEC definitions.

Windings

Stator winding and insulation classesLow voltage windings up to 690 V are madeof random wound enameled copper wire.All materials used including the vacuumpressure impregnation resin exceed thermalclass H (180°C) requirements. Class Htemperature rise is standard, with Class For B rise also available.

Medium and high voltage windings up to15 000 V are made of form wound rectangularcopper wire insulated with multiple layers ofglass-fiber reinforced mica-tape. A variable

number of layers of insulating tape can beapplied to the copper coil depending on thedielectric barrier defined by the voltage output.All materials used including the vacuum pressureimpregnation resin exceed thermal class F(155°C) requirements. Class F temperature riseis standard, with Class B rise also available.After insertion into the corresponding slots,the coils are firmly held in place by means ofsoft wedges and surge ropes at the coil headsprior to vacuum pressure impregnation.The completed process assures long andtrouble free service.

Form wound coils are used

for medium or high voltage

stators. High voltage coils

include a semiconducting layer

to decrease the electrical field

at the slot surface.


Rotor and exciter windingsRotor and exciter windings are made tomatch the insulation class of the stator.This ensures high reliability and a long servicelife even with asymmetric loads andexceptional conditions.

The rotor windings are made of pre-formedenameled rectangular copper wire.Proper supports between adjacent windings

are used to ensure stability up to the ratedoverspeed. The windings are vacuum pressureimpregnated.

Exciter windings are made of enamelledcopper wire. Proper glass fiber supports areused in the exciter rotor to ensure stabilityup to the rated overspeed. The windings arealso vacuum pressure impregnated.

The automated manufacturing process

uses ABB robots and is located in an

environmentally controlled area, ensuring

that each medium or high voltage coil is

produced with uniform and consistent

quality for the highest reliability.

Insulation


MCI insulation systemABB uses the MICADUR® Compact Industry(MCI) insulation system, which is based on thevacuum pressure impregnation (VPI) method.The vacuum pressure impregnation and curingof the completely wound and connected statorwinding with a specially formulated epoxy resinensures a sealed and homogenous insulationsystem, resulting in low dielectric strength,excellent heat transfer and elimination ofhazardous internal partial discharges.

ABB has been using the MCI system for morethan 25 years. In that time it has been used ontens of thousands of our larger machines, whichare operating successfully all over the world.No primary insulation failures due to thermalageing have been experienced. Thermal lifetimetests performed on the MCI system also showthat its endurance substantially exceeds IECand IEEE requirements.

MCI insulated windings require very littlemaintenance. Usually it is sufficient to ensurethat the cooling ability of the winding is notreduced by the ingress of moisture or dirt duringperiods when the generator is not operating.


The VPI process features:

� High vacuum cycle – removing air andmoisture from the voids and pores ofthe insulation.

� Highly stable epoxy resin – ensuringsuperior protection under the most difficultenvironmental conditions (against lubricants,diesel oil, moisture, common solvents,chemically aggressive gases, abrasive dust,tropical climate etc.).

� High pressure cycle – forcing the resininto even the smallest pores.

� Oven curing - after the VPI process hasbeen completed, stators and rotors are curedin an oven at high temperature. This producesvery strong and stable insulation, exhibitinghigh mechanical and electrical strength.This is especially important in order to resistinadvertent high stresses from out-of-phasesynchronization, transients and short circuits.

Even the largest wound stators and rotorsare impregnated as complete units. This ensuresthat both the insulation and the mechanicalproperties of the windings are excellent – whichmeans that they can withstand prime moverinduced vibrations and the mechanical stressescaused by transients such as short circuits.

Stator

Frames up to size 1120 are of modular type.The stator core is welded into a cylinder, afterwhich the end-modules with feet are weldedor bolted to the stator core. The bearings areflange-mounted on the end-shields.

For larger generators, full frames incorporatingboth the stator core housing and feet, are used.The bearings are mounted on pedestals integratedwith the frame, allowing installation of thegenerator as a fully assembled single unit.

The stator core itself is built of stacked, high-grade,

low-loss laminated electric sheet steel, insulated on

both sides with a heat-resistant inorganic coating.

Radial cooling ducts ensure uniform and effective

cooling of the stator.

The stator frame forms a rigid steel structure thathas been designed to withstand vibrations inducedby the prime mover.


Rotor

ShaftThe rotor comprises a shaft, a hub for largermachines, and salient poles. The shaft ismanufactured of forged or rolled steel andmachined to exact specifications. Rotors forframe sizes 1250 and greater are normallyequipped with a separate hub which isshrink-fitted onto the shaft. The shaft endsare normally cylindrical or flanged.

PolesThe poles are normally manufactured from2 mm laminated steel sheet. The sheets arepressed together with inserted steel barswhich are welded to the end plates.The pole structure is integrated or the poles

State-of-the-art rotor technology provides higher

efficiency and improved reliability.

The characteristics of the rotor play a crucialpart in achieving the best possible levels ofelectrical and mechanical performance.As a result, ABB continues its developmentwork to optimize rotor designs.

are secured to the shaft or hub by bolts fromabove or below, or by means of dovetails.The poles are fitted with a copper or brassdamper winding.

All rotor assemblies are vacuum pressureimpregnated (VPI) as complete units forexcellent insulation and mechanical strength.After impregnation, the complete rotor assemblyis dynamically balanced on two planes.

Excitation and regulation systems

All ABB synchronous generators have brushless excitationcontrolled by state-of-the-art automatic voltage regulators.The generators are self-excited, and do not require anyexternal source of excitation power.


Terminal BoxesThe integrated terminal box is locatedon top as standard and can be designedto allow cable entry from either the rightor left side.

For models up to AMG1120 the standardmethod of cable entry is from below,for AMG1250 or larger, from the side.Optionally, separate terminal boxes mountedon the side of the generator are available,featuring busbars outside the generatorframe and allowing connections fromany specified direction.

For auxiliary and instrument cablesseparate auxiliary terminal boxes maybe supplied as required.

Typical main components:1. Brushless exciter

� Rotor with three phase armature windingand rotating full-wave diode bridge rectifierfeeding main rotor field windings withDC current

� Stator with DC winding. The current tothe stator is supplied by AVR

� Complete exciter is mounted insidegenerator frame with easy access throughremovable inspection covers.

2. Automatic voltage regulator (AVR)Both analog and digital AVRs are available,type used depending on level of performanceand variety of functions required. AVR is eithermounted directly inside generator terminal box(small generators) or supplied on a mountingplate designed for installation inside generatingset control panel (large generators).Typical features of AVRs (depending ontype of AVR selected):� Voltage regulation in island mode with

droop-type reactive load sharing


Analog and digital AVRs are available for a perfect match with the application requirements.

� Auxiliary winding in stator, or� PMG (permanent magnet generator) mounted

outboard of the NDE bearing

4. Current transformer for actual value

measurement

� Used for reactive load control in eitherdroop or power factor control modes

Bearings

The choice of bearing arrangement and type isbased on factors such as load carrying capacity,speed of rotation, type of prime mover coupling,and client choice. Operating conditions such asambient temperature, air cleanliness, vibrations,shock and inclination (marine and offshoreplatforms) affecting the bearing are also takeninto account.

Antifriction bearings(standard for AMG 400-630)The bearing assembly is of the deep-grooveball type. The DE bearing is blocked while theNDE bearing is directly prestressed on the shaft.

Under normal operating conditions (lubrication,alignment, vibration, temperature andenvironment) and without undue externalload, the bearings are designed for a lifeexpectancy in excess of 50 000 hours.

A grease nipple is provided to ease periodicalchanging of the grease in the bearing assembly.Excess grease is ejected into a container that iseasily accessible for cleaning.

NDE bearings are insulated to prevent shaftcurrent circulation.


Flange sleeve bearings(standard for AMG 710-1120,optional for AMG400 to 630)Sleeve bearings are flange-mounted on theend-shield. Sleeve bearings withstand a highlevel of vibration. They offer excellent qualityand performance, as well as first-classreliability when driven by engines:� Because the bearing shells are seated in the

housing, the bearing assembly is highly suitable

for static as well as radial and axial dynamic loads.

� Excellent heat transfer through the contact

surface of the shells makes them especially

suitable for high speed applications.

� They are of the split type and easy to maintain.

Provided that the operating conditions arecarefully followed, their life expectancy ispractically infinite.

To prevent bearing damage from circulatingcurrents, all NDE bearing housings areelectrically insulated by means of nonconducting PTFE film.

The bearings are typically self-lubricated byoil ring. The lubricating oil is picked up by the oilring and transferred directly to the shaft.In the case of high ambient temperature or

inclined operating position (marineapplications) an external cooling circuit forthe oil may be necessary, unless the oilcomes direct from the engine cooled lubeoil system.

Integral pedestal sleeve bearings(standard for AMG1250-2500)These bearings have the same fundamentalfeatures as flange sleeve bearings, except thatthey are mounted on a pedestal that is integratedinto the stator frame. Generators with integralpedestal bearings are as easy to mount andalign as generators with flange mounted bearings.The generators are delivered ready assembledand require no further assemblyon site.

The air gap between the stator and rotor isalso factory set and does not need any furtheradjustment during coupling with the primemover.
