The fault was of resistive nature, was sensed from Hassan end in Zone-2 reach.

The DR from UPCL indicates resistive high current prior to operation of Zone-1

in C Phase. This is seen as development of Zero sequence voltage and current

prior to Zone -1 operation.

The operation of single phase Z1 from UPCL end was correct followed by

Sir,Sub: TANTRANSCO - PCSC Recommendations - Issue to be included in

Agenda for 52nd PCSC meeting - Requested - Reg.

*** * ***During the review of the tripp ing of 400kV Alamathy-S.V.Chatram Line-1 & 2

on 29.03.2015 at 15:29 hrs., PCSC Forum recommended to swap the Distance

Protection relays between two stations so that Main-1 and Main-2 will be of different

make at each Sub-station.

With reference to the above, the following issue may please be included in

the agenda for 52nd PCSC meeting:

1. In the Sub-stations with established Sub-station Automation System (SAS),

the integration of another make relay in SAS attracts additional expenditu re

which is many times the panel cost. It requires wiring modifications &

updation and the technical hitches are also to be attended.

2. Hence, it is requested that the forum may recommend to drop the protection

audit remarks and to continue with the present arrangement for the existing

Substations. However, different make Distance Protection relays will be

provided in the upcoming 230kV and above level Sub-stations.

Some notes regarding implementing Ramakrishna commission report based

settings in 220KV feeders.

(JAYARAJAN.C.N. EXECUTIVE ENGINEER, KERALA STATE ELECTRICITY BOARD)

1. Reverse Zone delay:

Case: In 220KV feeder relays, the delay is recommended as 0.5 seconds.

Issue: For long lines following short lines, the zone 2 delay is selected as 0.5 seconds. Often the

delay of zone 2 has to be increased from 0.35 seconds to 0.5 seconds especially in the case of

double circuits followed by short line. It has been observed that the lines like 220KV Sabarigiri-

Edamon which is passing through thick forests, trips in zone 2 (or zone 3) due to high resistance

faults. Resistive reach of reverse zone is selected as resistive reach of Zone 3. In such cases, reverse

zone in other feeders may operate before the tripping of faulty feeder.

Solution: a. Increase the resistive reach of zone 2 of protected feeder equal to zone 3 to get

maximum resistive reach.

b. Set Reverse zone time delay = zone 2 delay + breaker tripping time + relay reset time+

safety margin.

Recommended: It is safer to select delay of Zone 3 delay plus breaker tripping

time plus relay reset time = Zone 3 delay plus 200 ms. It may be noted that reverse zone is intended

to protect as back up to bus bar protection only and not for feeder protecton.

2. Power Swing Blocking and Load encroachment inhibit:

Case: Setting of Power swing blocking is based on minmum source impedance and initial swing

frequency as 1.5Hz.

Issue: a.The setting of power swing blocking in REL 670 is very difficult and different from other

relays. There is no common approach.

b. Selection of initial frequency as 1.5 Hz has not been verified by system studies.

c. The setting of Load Encroachment Inhibit feature in REL 670 relay is influenced by

setting of power swing blocking. Often load encroachment inhibit feature is extended to zone 2

reach. Load encroachment occurs in feeders with heavy overload which may increase sag of lines

leading to arcing to ground reulting high resistance fault. But Load encroachment inhibit feature

will block operation of the distance relay at this time even though there is a good chance for

occurrence of such fault. Directional earth fault protection has to take care of it.

Solution: a. Detailed discussion is required exclusively in setting of Power Swing Blocking and

Load encroachment inhibit.

b. Common approach in all relays is to be developed in the setting of Power swing

blocking and load encroachment inhibit.

c. Studies are to be carried out and values of initial and following power swing frequencies are to be

identified by system adminstrators.

3. Zone 3 delay:

Case: Zone 3 delay in 220KV feeders are suggested as 800ms.

Issue: Often zone 2 delay of distance relay in any of feeders from adjacent station may be 0.5

seconds. If the breaker of that feeder from adjacent station fails to operate for a fault in zone 2

reach, LBB protection of that particular breaker has to act before zone 3 operation of lines from

Annexure- V

Page 1 of 3

remote ends. Present zone 3 delay is not having sufficient margin with zone 2 of 0.5 seconds and

LBB delay of 0.2 seconds.

Solution: Increase Zone 3 delay has to be increased to at least 1 second in order to ensure security.

4. Grading of Zone 3 delay with protectons of transformer and its downstream side in the adjacent

station:

Case: Zone 3 delay of relay in a feeder has to be coordinated with protections in transformer and its

downstream side in adjacent station.

Issue and solutions:

(See the brief note given below regarding issues with Zone 3 reach.)

Zone 3 settings: Issues and suggestions – A brief note

Zone 3 settings are provided not for the protection of the feeder on which the relay is provided.

Zone 3 protection is supposed to act as back up to the protection provided in the feeders from

adjacent station.

However, in practice, it seen that it is very difficult to set Zone3 values. And it has been experienced

in India and aborad that Zone 3 protection has acted for heavy over loads during disturbed system

conditions which again worsened and collapsed the system.

Some examples:

a. On 30th

, July, 2012, the tripping of 400KV Bina-Gwalior 1 with Zone 3 indications led to

serious collapses. Actually, there was no fault in any of the line from adjacent station. However, it

was reported that system voltages were reduced and currents were increased due to overloading.

Similar incident was repeated on next day.

b. On 2nd

,July, 1996, the tripping of Mill Creek -Antellope of WSCC (Wersten North America) line

tripped undesirably on Zone 3 leading to cascaded tripping in many areas in Canada, Mexico,

California, Arizona etc. affecting two million people.

In such cases as above, the reason for maloperation of Zone 3 is due to stressed overloading and

stressed voltage conditions.

Therefore following points need attention:

1. Zone 3 operation makes maloperation than real operation.

2. The chances of operation of Zone 3 is very less except in the cases of high resistance fault

conditons which would otherwise would be sensed by directional earth fault (DEF) protection.

3. For avoiding maloperation load encroachment, Load Encroachment Inhibit feature may be

enabled for those ones having that feature. However, in relays like ABB's REL 670, it completely

blocks operation of distance protection even if high resistance earth faults may be developed as part

of severe overloading and due to conductor sagging. Operation of Directional earth fault becomes

critical then.

4. Extending reach of Zone 3 covering transformer impedance worsen security again. Following

points are to be noted in this case:

a. An earth fault on the downstream side is sometimes cleared by directional earth fault relay in the

feeder on the downstream side of the transformer in case of line faults or by transformer earth fault

Annexure- V

Page 2 of 3

relay. However, the time of operation inversely depends upon the magnitude of current which may

vary according to the resistance of earth fault path, source impedance etc. If Zone 3 is extended

upto downstream side, it is very difficult to grade with IDMT characterstics of earth fault relays in

feeders in downstream side and in transformer protection panels.

b. For solid fault in the downstream side of transformer, there will be significant infeed from

upstream side to the fault. This will under reach Zone 3 reach leading to non operation of Zone 3

protection. This shows that further delaying of Zone 3 in the name of coordinating with downstream

side earth fault or phase fault protection is of no use.

5. It is not practical to provide multipliers as much high as to compensate under reaching effect due

to heavy infeed in the case of Zone3. Because, the fault and system conditions are varying and this

may lead to expansion of Zone reach during low fault levels threating system security.

6. For 220KV and above systems, two redundant distance protections are used. Zone 2 protection is

set as 120 percent or 150 percent of the impedance of the protected line for ensuring 100 percent

feeder protection. Besides this, LBB protection will be in service in every such substations, which

trips all feeders and trasformers connected to the bus in case of breaker failure. Therefore, there is

practically no chance for Zone 3 protection to act for any fault in any of the lines from adjacent

station.

Considering the above facts, following steps can be taken as optimum solution:

1. Restrict Zone 3 protection reach upto longest line end from adjacent station. The equation: Zone

3 = 1.2* (impedance of protected line + impedance of longest line from adjacent station) is

acceptable. The multiplier 1.2 can be increased if only there is heavy infeed through out in service

duration.

2. Enable Directional overcurrent protection inside the distance protection and set the same in such

way to coordinate the same with transformer overcurrent protection in the adjacent station.

Similarly, set the pick up value of directional earth fault relay in the protected line to sense the

lowest earth fault current in the downstream side of the transformer. It may please be noted that

these protections are supposed only to ensure tripping and fault isolation in the extreme cases.

3. Set time delay of Zone 3 to 1 second or in extreme cases to 1.5 seconds. In KSEB, back up

impedance setting of generators are set at 2.5 seconds to act as back up to all protections in the

downstream side. Therefore, Zone 3 delay can not be increased too much which may lead to

generator tripping.

Presently KSEB is following the procedure similar to the above suggestion to a good extent.

This is forwarded for favour of information and further necessary action. Please note that these are

only suggestions to be discussed and to be corrected and modified, if necessary.
