INTRODUCTION

The UM30-SV relay provides all of the voltage andfrequency-related functions necessary for the protectionof a feeder or rotating equipment. Three digital inputs areavailable to provide selective blocking of variousfunctions. Five output relays are provided, of which fourare programmable. All settings, measurements, andprogramming of the relay are possible through its frontpanel controls, or by means of a computer connected tothe relays RS485 communications port. The functionsprovided by the UM30-SV are:

Vector Jump element which detects the step changein frequency that occurs when a generator and localload is suddenly disconnected, or islanded, from therest of the power system.

Two frequency levels each programmable to beunder (81), or over and under (81)definite time frequency elements.

Two definite time voltage elements each configurableas either under (27), over (59), or over and under (27and 59) elements.

One positive (direct) sequence voltage levelconfigurable as either an under (27pos), over

(59pos), or under and over (27pos + 59 pos). One negative sequence overvoltage element

(59neg).

Two zero sequence overvoltage levels (59zero) withindication of the faulted phase.

Overexcitation (24).protection provided by a low setinverse time and high set definite time elements.

Three blocking inputs to control operation of thevarious protective elements.

Separate pickup functions are also provided for allelements which may be used to operate output relays toin order to implement various control, blocking, logic, or

SCADA functions.

APPLICATIONS

The UM30SV is ideally suited for use on utility systemsfor the detection of generator islanding through the use ofa vector jump, or vector surge, element.

The UM30SV may also be used as a general purposevoltage and frequency relay. Because of the manyfunctions included in the UM30SV, it can easily be usedin many protection schemes including:

Frequency based load shedding for industrial or co-gen environments where the need to shed internalplant load, or to break ties to the supply utility, isrequired in order to protect local generation or criticalprocesses.

Automatic sectionalizing or deadline throw-over,

Generator or motor bus under and overvoltageconditions.

Single phasing of motors.

Grounding of one phase on a delta or ungroundedsystem.

Additionally the two levels of overexcitation (V/Hz)combined with the voltage functions make the UM30SVsuitable as part of a generator protection package.

Although the UM30SV is intended as a three phase relay,it may be used as a single phase relay with only the A-phase input connected. Certain functions will not beoperable in this mode, specifically the vector jump

element in three phase mode, and the positive, negative,and zero sequence voltage elements.

VECTOR JUMP FUNCTION

In the case of a generator operating in parallel with adistribution network, when the network is suddenlydisconnected, the generator becomes islanded and isleft to supply the all of the remaining connected load,including the share of load formerly supplied by thenetwork.

The UM30SV relay includes an element designed todetect the disturbance produced by the sudden variationof the load at the terminals of a generator. This

disturbance results in a proportional variation of theangular displacement between the generatorselectromotive force E and the voltage at its terminals orpoint of relaying, V. See Figures 1 and 2.

The resulting of the angle h is referred to as aVector Jump or vector surge. If the circuit breakerconnecting the islanded generator to the rest of thenetwork is automatically reclosed, it is possible that thevoltage displacement between the generators bus andthe network can be too large for safe paralleling of thegenerators.

Rapid detection of this condition provides the opportunity

to: Trip the generators circuit breaker or the utility tie

breaker before the reclosing of the tie utilitys breakeroccurs thus avoiding possible serious damages tothe generator itself.

Tripping of non-critical local load in order to matchthe generators output to supply critical processes inan industrial environment.

The relay can detect a Vector Jump adjustable from 2 to30 giving out a trip signal in less than 3 cycles. SeeFigure 3. The UM30SV uses a moving average of the last

5 cycles periods as a comparison value in order toreduce spurious operations.

The detection of the disturbance can be made in either 1-phase or 3-phase modes.

In the 1-phase mode tripping takes place as soon as

a measured exceeding the set level is detected

on one of the three phase voltages. In the 3-phase mode tripping takes place only if the a

value of above the set level is detected on all thethree phases at the same time.

Single-phase mode is more sensitive than three phasemode to detecting Vector Jump conditions, however it isalso more sensitive to spurious disturbances.

An undervoltage element blocks the Vector Jumpfunction if the voltage drops below an adjustable levelthreshold, Vb.

A contact input operated by a normally open auxiliarycontact (52a) of a Circuit Breaker blocks the Vector Jump

functions when the Circuit Breaker is open as well as for5 seconds after closing the breaker.

The value of as a function of the power variation of

the generator (P) as it passes from the normal situationto an islanded situation may be approximated as:

= (0.3 0.4) P

Where the 0.3 multiple is generally more applicable tolarge generators, and the 0.4 multiple to smallgenerators.

The use of a computer based transients analysis

program to accurately determine the setting isrecommended to avoid spurious trips.

OVEREXCITATION

The UM30SV uses a two level over-excitation elementwhere the low set level follows an inverse timecharacteristic, and the high set element is definite time.See Figure 4.

HANDLING

As with any piece of electronic equipment, care should betaken when handling the relay, particularly in regards toelectrostatic discharge as the damage may not beimmediately obvious. All Edisonrelays are immune toelectrostatic discharge when left in their protective case.

However, when the relay is removed from its case, thefollowing practices should be observed.

Touch the case to ensure that your body and therelay are at the same potential.

Whenever possible, handle the exposed relay by thefront panel, the rear connector, or by the edges of theprinted circuit boards. Avoid touching the individualelectronic components or the embedded traces onthe circuit boards.

If you must hand the exposed (i.e., drawn-out) relayto another person, make sure you are both at thesame electrical potential.

When setting the drawn-out relay down, make surethe surface is either anti-static in nature or is at thesame electrical potential as your body.

Relays should always be placed in storage in theirprotective cases. If storage of the drawn-out relayoutside of its protective case is required, then theexposed relay should be placed in a suitable antistatic plastic or foam container.

INSTALLATION

Edison M Series relays are shipped either in single ordouble width cases, or in standard 19 3RU rack mount

enclosures capable of housing up to four M Seriesrelays. The double case mounting is similar to the singlecase, but requires a 235 x 142mm panel opening. The19 rack mount case is a standard 3RU high 19 cabinet.See catalog section 150-00 for cabinet dimensions.

To remove the relay from its case, refer to Figure 5. The

relay may be removed from its protective case by turningwith a flat bladed screwdriver the locking screws and on the front panel latches so that the slot on the screwis parallel to the ground. The latches may then be pulledfrom the inside edge to release the relay. Carefully pull onthe latches to remove the relay from the housing.

To re-install the relay in its case, align the printed circuitboards with the guides in the relay case and slide therelay in most of the way. For single and double cases,make sure the locking arm on the back of each of thelatches lines up with the locking pins in the case. Thenpush the latches in, seating the relay. Turn the screws onthe latches until the slot is perpendicular to the ground.

ELECTRICAL CONNECTIONS

Power is supplied via terminals 12 and 13, with commonat terminal 44. Chassis ground is made via the externalscrew provided on the case. All Series M relays areavailable with one of two autoranging power supplies.Descriptions of the input voltage ranges are given inTable 1. The input supply voltage is noted on the relaycase. In the event the relay is fitted with the incorrectpower supply, the power supply boards are easily fieldreplaceable. See Bulletin S150-99-1 for instructions andpart numbers.

All electrical connections, including the RS485connections, are made on the back of the relay. SeeFigure 6. All the terminals will accept up to a No. 6 studsize spade connector (or any type of lug up to 0.25wide), 12 AWG wire (4 mm), or FASTON connectors.

Electrical connections must be made in accordance withthe relays wiring diagram found in Figure 7. Thenumbers next to the circles along the edge of thefunctional block diagram of the relay indicate the terminalnumbers corresponding to the terminal numbers on the

back of the relay as shown in Figure 6. The VT inputsmust provide the relay with phase-to-ground voltages perthe phase rotation shown.

OUTPUT RELAYS

Output relays 1 through 4 are user programmable tooperate in conjunction with the tripping of any protectiveelement or elements. Relay 1 (R1) consists of twoisolated SPST (one From A and one Form B) terminalsas being either normally open or normally closed. The

other three output relays, R2, R3, and R4, all have FormC (i.e., SPDT) contact arrangements.

Output relay 5 is normally energized (shown de-energized) and operates only upon power supply failureor on an internal relay fault.

BLOCKING INPUTS

The UM30-SV has three inputs, which perform blockingfunctions. The open circuit voltage across the terminalsof these inputs is 15 VDC. The internal resistance is 2.2 k

. When the external resistance across these terminals

is less than 2.0k, they are considered to be shorted.See Programming the Relay for more information on thefunction of these inputs.
