HERE IS AN EXAMPLE OF HOW VARIABLE SPEED CAN EFFECT SYSTEMOPERATION.WHILE GOING TO WORK, YOUR HIGHEST SPEED WAS 55MPH. WOULD YOU

ACCELERATE TO 55MPH, AND SET YOUR CRUISE CONTROL? THEN CONTROLYOUR ACTUAL SPEED BY APPLYING VARYING AMOUNTS OF BRAKE PRESSURE?

OUR CARS ARE A FORM OF VARIABLE SPEED DRIVE. THE THROTTLE (ORCRUISE CONTROL) DETERMINES THE SPEED OF THE CAR

.

CRUISE CONTROL) DETERMINES THE SPEED OF THE CAR. THIS IS NOT HOW WE OPERATE PUMPS AND FANS. WE TURN ON AN ELECTRICMOTOR AT SAY 1750 RPM, AND THEN GOVERN THE FLOW THROUGH THE PIPESOR DUCTS BY OPENING AND CLOSING VALVES OR DAMPERS.CAN YOU IMAGINE THE WEAR AND TEAR ON YOUR VEHICLE, THE FUEL

MILEAGE, AND NOT TO MENTION HOW STRONG YOUR LEG WOULD GET?

THERE ARE OCCASIONS WHEN YOU MIGHT WANT TO PERMANENTLYCHANGE THE AMOUNT OF FLUID OR AIR YOU'RE PUMPING. THERE AREFOUR WAYS YOU COULD DO THIS:

REGULATE THE DISCHARGE OF THE PUMP. CHANGE THE SPEED OF THE PUMP. CHANGE THE DIAMETER OF THE IMPELLER. PURCHASE A NEW PUMP

ENERGY SAVINGS

.

OF THE FOUR METHODS THE MIDDLE TWO ARE THE ONLY SENSIBLEONES. IN THE FOLLOWING PARAGRAPHS WE'LL LEARN WHAT HAPPENSWHEN WE CHANGE THE PUMP SPEED, AND AS YOU WOULD GUESS, OTHER CHARACTERISTICS OF THE PUMP ARE GOING TO CHANGEALONG WITH SPEED.

EXAMPLE:IF YOU WANTED TO REDUCE THE SPEED OF A PUMP TO 50%NEW SPEED/OLD SPEED = 1750/3500 = 0.5THE CAPACITY, OR AMOUNT OF FLUID YOU'RE PUMPING, VARIES DIRECTLYWITH THIS NUMBER.EX: 100 GPM X 0.5 = 50 GPM

THE HORSEPOWER REQUIRED CHANGES BY THE CUBE OF THE NUMBER

ENERGY SAVINGS

.

THE HORSEPOWER REQUIRED CHANGES BY THE CUBE OF THE NUMBER.EX : A 72 HORSEPOWER MOTOR WAS REQUIRED TO DRIVE THE PUMP AT 3500 RPM.. HOW MUCH IS REQUIRED NOW THAT YOU ARE GOING TO 1750 RPM? EXAMPLE: 72 X 0.125 (0.5)*(0.5)*(0.5) = 9 HORSEPOWER IS NOWREQUIRED.

I = E/(R+2pFL)

THEREFORE,

FOR I TO REMAIN CONSTANT, IF F IS LOWERED,E MUST ALSO BE LOWERED.

CURRENT IN A MOTOR IS EQUAL TO I=E/(R+XL)

AS THE FREQUENCY TO A MOTOR IS DECREASED, XL DECREASES.BECAUSE XL DECREASES, E MUST DECREASE PROPORTIONALLY TO KEEP I THE SAME

IN CASE OF LV VOLTAGE:

THE 24-PULSE TRANSFORMER DRIVE HAS A SLIGHTLY BETTER CANCELLATION OFINPUT HARMONICS THAN THE18-PULSE ONE. THE 18-PULSE METHOD IS RECOGNIZEDBY THE INDUSTRY AND CONSULTING ENGINEERS THOUGH AS A VIABLE SOLUTION FORHARMONIC MITIGATION AND MEETING IEEE519 GUIDELINES.

INITIAL COSTS FOR THE 24-PULSE DRIVE WILL BE HIGHER (ESTIMATED TO 30% HIGHER THAN THE 18-PULSE VSD COST WITH ISOLATION TRANSFORMER)

.

ALSO, THE FOOTPRINT FOR THE 24-PULSE WILL BE LARGER (ESTIMATED FROM10 TO15% BIGGER)

EMI / RFI

ELECTROMAGNETIC INTERFERENCE (OR EMI, ALSO CALLED RADIO FREQUENCYINTERFERENCE OR RFI) IS A DISTURBANCE THAT AFFECTS AN ELECTRICAL CIRCUITDUE TO EITHER ELECTROMAGNETIC CONDUCTION OR ELECTROMAGNETICRADIATION EMITTED FROM AN EXTERNAL SOURCE.

RFI IS A SUBSET OF ELECTRICAL NOISE ON THE EMI SPECTRUM.

THE DISTURBANCE MAY INTERRUPT, OBSTRUCT, OR OTHERWISE DEGRADE ORLIMIT THE EFFECTIVE PERFORMANCE OF THE CIRCUIT

.

LIMIT THE EFFECTIVE PERFORMANCE OF THE CIRCUIT.

EMI CAN BE INTENTIONALLY USED FOR RADIO JAMMING, AS IN SOME FORMS OFELECTRONIC WARFARE, OR CAN OCCUR UNINTENTIONALLY, AS A RESULT OFSPURIOUS EMISSIONS FOR EXAMPLE THROUGH INTERMODULATION PRODUCTS, AND THE LIKE. IT FREQUENTLY AFFECTS THE RECEPTION OF AM RADIO IN URBANAREAS. IT CAN ALSO AFFECT CELL PHONE, FM RADIO AND TELEVISIONRECEPTION, ALTHOUGH TO A LESSER EXTENT.

VFD - EMI / RFI

VFD GENERATES RFI IN THE RANGE OF 0.5MHZ TO 1.7MHZ AND EMI IN THERANGE OF 1.7MHZ TO 30MHZ.

THE HIGH FREQUENCY GENERATION IS CAUSED BY THE HIGH CARRIERFREQUENCIES OF THE PULSE-WIDTH MODULATION, THE ASSOCIATED SHORT RISETIMES OF THE IGBT OUTPUT DEVICES, AND THE REFLECTED WAVES FROM THEMOTOR TERMINALS.

EMI IS ALSO PRODUCED BY THE HARMONICS WHICH ARE GENERATED BY THE

.

EMI IS ALSO PRODUCED BY THE HARMONICS WHICH ARE GENERATED BY THECARRIER FREQUENCIES, RISE TIMES AND REFLECTED WAVES.

VFD - EMI / RFI

THE EMI/RFI WILL TRAVEL TO THE MOTOR ALONG THE MOTOR LEADS AND WILLBE TRANSMITTED TO GROUND VIA THE CAPACITIVE EFFECT BETWEEN THE MOTORWINDINGS AND THE MOTOR FRAME, THE CAPACITIVE EFFECT BETWEEN THE LINECONDUCTORS AND BOND WIRE, AND THE CAPACITIVE EFFECT BETWEEN THE LINECONDUCTORS AND CONDUIT. THE EMI/RFI WILL THEN SEEK A RETURN PATH TOTHE SOURCE, THAT IS, TO THE INPUT OF THE VFD.

THE RETURN PATH TO THE INPUT POWER TERMINALS OF THE VFD WILL BE FROMTHE GROUND GRID THROUGH THE GROUNDED NEUTRAL OF THE WYE SECONDARY

.

THE GROUND GRID THROUGH THE GROUNDED NEUTRAL OF THE WYE SECONDARYOF THE UPSTREAM POWER DISTRIBUTION TRANSFORMER AND THROUGH THATTRANSFORMER’S LOAD LINES.

VFD - EMI / RFI – SOLUTION - 1

AN EMI/RFI FILTER AT THE DRIVE INPUT TERMINALS WILL PROVIDE A RETURN PATHFOR NOISE THAT WILL EFFECTIVELY REDUCE THE DISTANCE OF NOISE TRAVEL ALONGTHE GROUND GRID AND KEEP THE NOISE AWAY FROM THE UPSTREAM TRANSFORMERAND INCOMING POWER LINES.

.

VFD - EMI / RFI - SOLUTION - 2

A DRIVE ISOLATION TRANSFORMER WITH A SOLIDLY GROUNDED NEUTRAL WILL ALSOPROVIDE A RETURN PATH THAT WILL KEEP THE NOISE AWAY FROM THE UPSTREAMTRANSFORMER AND INCOMING POWER LINES.

.

VFD - EMI / RFI - SOLUTION - 3

BOTH A LOAD REACTOR OR A DV/DT FILTER WILL REDUCE THE HIGH RATE OF CHANGEOF OUTPUT VOLTAGE WHICH IS CAUSED BY THE RAPID SWITCHING OF THE IGBT DEVICES.

THE REDUCTION OF THE RATE OF CHANGE OF VOLTAGE WILL REDUCE THECAPACITIVE EFFECTS WHICH CAUSE EMI/RFI. THUS, A LOAD REACTOR OR DV/DTFILTER WIRED DIRECTLY TO THE OUTPUT TERMINALS OF A VFD WILL REDUCE BOTHCOMMON MODE NOISE AND DIFFERENTIAL NOISE

.

COMMON MODE NOISE AND DIFFERENTIAL NOISE.

IN ADDITION TO REDUCING THE RATE OF CHANGE OF OUTPUT VOLTAGE, THEFILTERING OF THE HIGH CARRIER FREQUENCIES VIA A DV/DT FILTER WILL ALSO YIELDA REDUCTION OF THE IMPEDANCE MIS-MATCH AT THE MOTOR TERMINALS AND, CONSEQUENTLY, A REDUCTION IN THE REFLECTED WAVE. A DV/DT FILTER CONSISTSOF A LOAD REACTOR WITH A PARALLEL CAPACITOR.

Synchronous Transfer

.

The W7/HX7 drive has integral standard drive control intelligence to accelerate a connected motor to the exact power line frequency and connect this motor to the utility source smoothly with virtually no current or torque disturbance.

Synchronous Transfer ability offers a user several important operational benefits:

(1) A single drive can be used to accelerate multiple motors to synchronous line speed, minimizing drive investment.

(2) A single drive can be shared by a group of motors, with one or more of the motors being run on the VFD while other motors are running at fixed speed. This allows optimizing process control, and maximizing energy


.

p p g p g gyutilization.

(3) When the process requires full -speed operation, a connected motor can be returned directly to the utility, maximizing energy efficiency by eliminating any losses introduced by drive operation.

(4) Multiple motors can be "soft started" sequentially, minimizing power line surges and impact.

Synchronous Transfer Sequence of Operation

•Output inductor L0 is included to eliminate instantaneous inverter over currents and output difficulties during the instant of the closed - transition between the inverter and the power line. The size of the inductor is selected dependent upon the total impedance of the utility source in comparison to the connected motor load.

.


•The drive control monitors current flowing into the motor through the newly-established bypass utility power feed through contactor M11

•When the drive control determines that proper levels of utility line current are flowing into the connected motor, the synchronizing process is considered

•The inverter power switch gating circuits are blocked, and the inverter output stops.

Synchronous Capture Sequence of Operation

•Consider that the motor is connected to the utility line through contactor M11, and is turning its connected load at a speed equivalent to its nameplate RPM.

•A contact is received from the user requesting the motor to be desynchronized / Captured.

T300MVi

MEDIUM VOLTAGE DRIVES


Built in Harmonic Reduction, without Filtering or Concern for Long Lead LengthsDue to a specially designed transformer and rectifier scheme that provides phase shift cancellation capabilities, previous issues concerning harmonic injections into bus fed equipment are no longer a concern. Instead, the T300MVi medium voltgage drive simply looks like a linear load on the incoming AC line. It also exceeds IEEE 519 requirements without the addition of any harmonic filters.Other benefits:• Topology provides isolation from ground faults and line surges.• Design obtains a higher displacement power factor (0.96) than running the motor across the line. • Motor torque ripple is negligible due to extremely small harmonic current contents reducing the need for damping

devices, e.g., couplings, flywheels.• Reduces the possibility of drive-induced torsional vibration in the driven equipment.

Diagram represents standard product offering T300MVi medium voltage drive1000-2000 HP, 4160 V Input. This product was specially designed to have one of the smallest footprints offered by any manufacturer.

Stable Speed Control without a Speed Sensing Device• Provides V/Hz or vector control performance without a

motor mounted digital or analog sensor.• Controls industrial processes utilizing an internal, high

speed algorithm.• Capable of closed loop vector control for super high

performance applications.

Continuous Operation During Momentary Power Failures• Operates with a 30% undervoltage condition (trip time

based on drive overload).• Five-cycle ride through during complete outages.• Contains automatic ride through control.• Allows restarting into a rotating load upon restoration of

AC line power following a total power loss.

IGBT Technology: Tried and TrueOver the years IGBT, technology has proven to be the most reliable and best performing means of speed control in low voltage drives. Toshiba has not only mastered this technology, we continue to excel at it. It is with this in mind that the T300MVi drive is designed using both diodes and IGBTs in the main power circuit. Through extensive experience we are able to offer a control circuit topology providing higher performance than our competition, using fewer parts. What does this mean to our customers? Plain and simple; fewer parts means lower maintenance. This philosophy is integrated into our modular vertical design to provide both power module interchangeability and smaller footprints than the competitors.

Some other advantages of IGBT technology:

• Inherent short circuit and ground fault immunity at the output• Lower gating power requirements• Small snubber circuitry required

Multi-Level PWM Output Closely Simulates True Sinewave The T300MVi drive employs several layers of switching devices to provide a smooth output wave shape to the motor. The multi-step output closely simulates sine waveshape, virtually eliminating motor failures due to insulation stress and long lead length issues.

The T300MVi driveʼs topology allows retrofitting to existing medium voltage motors without upgrading motor insulation.It also:• Eliminates the need for an output transformer, reducing cost and size• Allows the use of standard bearings without grounding or isolation means• Operates the motor at design rating (maximum) Enables easy retrofit

All T300MVi drives use a three power module design for reduced MTTR. The special racking mechanism extends from the drive and allows module inspection. In addition, the drive doesn’t contain fans, contactors, or large electrolytic capacitors.

Toshiba guarantees the T300MVi product line will meet

or exceed IEEE-519 standards as advertised at input to the drive.

Thus, the drive appears to be a linear load to the power system.

The design eliminates the need for costly and time-consuming

harmonic analysis.
