3. Out-of-Step (78) Relay Setting Philosophy - the application follows the approach outlined in GE technical

reference GER-3179, Out-of-Step Protection for Generators. This approach utilizes two impedance relays (OUTER

unit and INNER unit) to track the impedance locus of the generator during an out-of-step swing. The objective is to

detect that the generator is going out of step and initiate separation from the system during the first swing.

Traditionally, a 120° separation has been considered the criterion to define an out-of-step condition. The INNER unit

is set at the points at which the generator and system are 120° and 240° apart. The OUTER unit is set to avoid

tripping on stable swings, and to initiate separation when the generator voltage approaches 300° with respect to the

system. This assures that the maximum voltage angle across the breaker at the time that it opens will be 60° or less.

The impedance locus of most out-of-step swings passes through the generator step-up (GSU) transformer, or the

generator itself (relatively closer to the line-side terminals). For this reason, GER-3179 suggests that with the relay

applied at the generator terminals and polarized to look toward the system, the reverse reach into the machine should

be two to three times the generator transient reactance (X'dv). The forward reach into the system should extend well

past the high-voltage terminals of the GSU, and forward reach settings typically fall in the range of one to two times

the GSU leakage impedance.

Critical clearing time is defined as the maximal fault duration for which the generator remains transiently stable during

power swings. Two dynamic simulations were conducted: HV 3-Phase fault and generator bus fault. Time intervals at

60, 120, 240 and 300 degrees between generator and system are calculated to insure a loss-of-synchronism

condition exists. Analysis conducted using unit specifications and below pre-fault conditions. Simulation assumes all

units on line, all line in service. Note the Y-axis is the rotor angle.

protection for the generator and should be set as sensitive as possible, yet

not trip for CT errors that can occur during an external fault. Slope 1 and

pickup of 10% and 0.1 per unit respectively are recommended for this

application. Break 1 should be set marginally above the machine rating.

Break 2 should be set lower than the saturation curve kneepoint and coordinate

with the maximum generator fault current contribution.

Relay Setting Philosophy: During loss of excitation, these relay functions will

detect vars. from the system into the generator. The offset of X’DV / 2 is to

avoid misoperations during system faults. The 40-1 circle is set at 1.0 per unit

ohms (on generator base) in order to detect short circuited fields at full and

moderate load, while not tripping for stable swings or regulator undershoot.

The 40-2 circle is set at XDV with a time delayof 0.6 seconds to provide tripping

for short circuited fields at no load or open circuit field, while not tripping for

stable swings. This function should be blocked for VTFF.Convert X’DV and XDV from per unit on gen. MVA and kV bases to relay ohms:

CT Ratio (CTR): 15,000 / 1 = 15,000 :1

PT Ratio (PTR): 15,000 / 110 = 136.36 :1


Relay Setting Philosophy: Gas turbines require 10 - 50% of rated power

to motor depending on design. 32-STG1 pickup settings should be 7% of

rating. 32-STG2 will be disabled. This function should be blocked for VTFF.

This function is blocked during startup.

gas turbines set for instantaneous breaker trip at 94% speed and alarm at 108%

Stator Ground Fault 3RD Harmonic Undervoltage Function (ANSI Device 27TN)

A) Generator Data


B) Relay Data

27TN Relay Ranges: 0 - 3.0 per unit Volts pickup range



Relay Setting Philosophy: The 27TN function is set during commissioning to

cover the last several percent of the stator closest to the neutral. The 27TN

pickup setting must be based upon the minimum measured 3RD harmonic

voltage appearing across the resistor (NGR) in the neutral grounding transformer.This voltage can be internally monitored using the data accumulated in the

DATA LOGGER. DATA LOGGER has been programmed to capture this data and

the 27TN function has temporary settings for 3rd harmonic voltage measurement.

The following procedure should be used to set the the 27TN function:

1 Obtain the minimum 3rd harmonic voltage across the NGR by methods

described above during generator load testing.

2 Program the G60 3RD HARM NTRL UV PICKUP setting to be one half of the

min. observed 3rd harmonic voltage across the NGR in per unit on 240V base.

This setting may be entered in steps of 0.001 puV

3 Program the G60 27TN time delay setting to 5 seconds.4 Program the G60 27TN MIN POWER pickup setting for the lower per-unit

power level in which the measured 3RD harmonic voltage falls

below 0.2 volts. Set for 0 if minimum does not fall below 0.2V.

5 Program the DGP 27TN MAX POWER pickup setting for the higher per-unit

power level in which the measured 3RD harmonic voltage falls

below 0.2 volts. Set for 0 if minimum does not fall below 0.2V.

6 Enable the 3RD HARM NTRL UV function.

This function will be blocked during startup.

Relay Ranges: Percent Differential: 0.05 to 1.00 * 5A in 0.01 steps

Slope 1: 15-100%, Slope 2: 50-100%, Break 1: 1.0-2.0, Break 2: 2.0-30.0

Winding F1 Phase CT Ratio: 15,000 / 1 Generator Neutral CTs

Winding M1 Phase CT Ratio: 15,000 / 1 UAT High Side CTs

Winding M5 Phase CT Ratio: 600 / 1 GSU HV Side CTs

Winding M5 Ntrl CT Ratio: 600 / 1 GSU HV Side Neutral CTs

C) Differential Protection (87U) Settings Calculations

Setting Philosophy: 87U function uses internally compensated values of current.

Differential current setting (IDIFF ) = IF1 + IM1 + IM5. Differential instantaneous function

will operate for faults within the differential zone. The differential function will be

blocked using the average adaptive 2nd harmonic inrush inhibit function as well as

the 5th harmonic overexcitation inhibit function. The reference winding will be F1.

Reference Winding and Magnitude Compensation Calculations

IF1 = (MVAT) / (3 * LV) = 13,086 A Imargin = CTF1/IF1 = 1.146

IM5 = (MVAT - MVAUAT) / (3*HV) = 352.2 A Imargin = CTM5/IM5 = 1.704

IM1 = (MVAUAT) / (3 * LV) = 1,347.1 A Imargin = CTM1/IM1 = 11.135

Magnitude Compensation F1= [CTF1 x kV(LV)] / [CTF1 x kV(LV)] = 1.00 = MCF1

Magnitude Compensation M5= [CTM5 x kV(HV)] / [CTF1 x kV(LV)] = 1.33 = MCM5

Magnitude Compensation M1= [CTM1 x kV(LV)] / [CTF1 x kV(LV)] = 1.00 = MCM1

Expected Currents Through Each Winding During Normal Operation

IF1 = (MVAGEN) / (3 * LV) = 12,432 A, = 0.829 x CTF1= 1.00 pu

IM5 = (MVAGEN - MVAUAT) / (3 * HV) = 332.5 A, = 0.554 x CTM5= -0.89 pu

IM1 = (MVAUAT) / (3 * LV) = 1,347 A, = 0.090 x CTM1= -0.11 pu

IDIFF = IF1 + IM1 + IM5 = 0.000 pu ==> use 0.3pu pickup for % Diff

Expected Currents Through Each Winding During Startup Operation

IF1 = Max LCI current = 1,500 A, = 0.100 pu

IDIFF = IF1 + IM1 + IM5 = 0.100 pu ==> use >0.1pu pickup for % Diff

D) HV Winding Restricted Ground Fault (87GT) Settings Calculations

Setting Philosophy: 87GT protection provides sensitive ground fault detection for low-

magnitude fault currents, primarily those close to the neutral point of a Wye-connected

winding. The transformer differential (87U), with differential current pickup of 0.2 per unit,will not detect HV winding earth faults with magnitudes less than 4500 A. 87GT ground

differential current, IG + IN + IA + IB + IC, is measured from the HV phase and ground CTs.
