Minutes of the Meeting of Protection System Analysis Group - 16 (PSAG-16) held

on 18th July, 2016 at 220/110 kV Ambewadi SS of KPTCL

Introduction

The Protection System Analysis Group (PSAG-16) meeting was held on 18th July, 2016 at

Ambewadi Substation of KPTCL. Shri. Harish K. Nayak, Executive Engineer (El), TL & SS Division,

welcomed the members and participants and briefed regarding the Grid Disturbance (GD) that

occurred at Ambewadi on 24.06.2016. The list of participants is enclosed at Annexure-I.

Ambewadi on 220 kV side has six grid-connected feeders including two inter-state lines, [viz.,

220 kV Ambewadi-Nagjhari lines – 1&2, 220 kV Ambewadi-Narendra lines – 1&2, and 220 kV

Ambewadi-Ponda-1 (Xeldem) line, Ambewadi-Ponda-2 (Ponda) line] and 2x100 MVA, 220/110

kV Transformers. On 110 kV side, it has total four feeders, out of which two are connected to

Supa generating station, another feeder connected to Haliyal SS and the other to Kawalwad SS.

It has been observed that even though the substation has been designed for double-bus with

bus-coupler switching scheme, as bus-CVT of one bus is not in healthy condition, the other bus

only is being used by keeping the bus-coupler breaker out of service. Thus, functionally

substation is on Single Bus Operation. The Single Line Diagram and Connectivity Diagram of

Ambewadi SS are enclosed at Annexure-II.

The following issues were deliberated in the meeting:

A. Analysis of the Grid Disturbance that occurred at 220kV Ambewadi SS on 24.06.2016

A.1 Pre-fault Scenario:

There was no generation at Nagjhari PH and Supa PH.

220kV Ambewadi-Ponda line 2 was idle-charged from Ambewadi end.

220kV Ambewadi-Ponda line 1 (Xeldem) was feeding radial loads.

220/110kV Ambewadi ICT-I & II were feeding radial loads (110kV Ambewadi-Kawalwad &

110kV Haliyal-Kawalwad were in open condition).

Auto-reclosure (A/R) scheme was enabled only in 220kV Ambewadi-Ponda line-2 on

23.06.2016 at Ambewadi end. .

A.2 Sequence of occurrence of faults:

A.2.1 Y-B fault in Ambewadi-Ponda line-2 at 20:23 hrs:

R

Y

B

Line tripped (in 3-ph) at 20:23 Hrs on Y-B fault due to DPR, Z1 operation (3000 A; 64 km

from Ambewadi end). From DR, fault was observed to be cleared in-time in about 60ms.

Ambewadi Ponda

Minutes of the PSAG-16 Meeting held on 18.07.2016 at Ambewadi SS Page 2

KPTCL informed that the fault occurred due to Y-ph Jumper cutting (on Ponda side) and

falling on B-phase conductor causing arc between the broken conductor edges. The said

incident was stated to have happened at Location No. 176 in Goa area.

A.2.2 B-E fault in Ambewadi-Ponda line-2 at 20:44 hrs:

R

Y

B

Subsequently, line was attempted to be test-charged at 20:44 hrs but tripped (in B-ph) on

B-E fault due to DPR, Z1 (A/R) operation. Fault was observed to be cleared in-time in

about 100 msec. KPTCL informed that the falling of Y-ph conductor on to B-ph conductor

had caused the B-E fault. It was noted that SOTF protection which was supposed to

operate and give 3-ph trip under these conditions had not operated. Due to this, A/R

operated to open the line in faulty phase (B-ph). It was also noted that SOTF had been

enabled with a comparatively high-setting of I(op) > 3A for Ponda-2 line. For all others

lines it had been kept in disabled condition.

After the dead-time of 1 sec, line tried for auto-reclosure, but remained unsuccessful due

to problem in A/R output contacts of the distance relay. It was noted that Pole

Discrepancy Relay which was supposed to operate under these circumstances remained

ineffective due to the problem B-ph auxiliary switch of the circuit breaker (CB). KPTCL

informed that this was subsequently set-right. It was later found out by the station staff

that the breaker’s close-contact of A/R of Ponda-2 got wedged/ welded during the incident.

This was also confirmed by measuring resistance (which was around 25 ohms) across those

contacts.

Now, after some time, control room personnel observed smoke in Ponda-2 distance Relay,

and immediately switched off the Main DC supply for Ponda-2 line relay panels to prevent

undue damage.

Considering the above sequence of events, and the past history of Ambewadi SS, the

possible reason for smoke and subsequent damage to Ponda-2 distance relay could be

attributed to sudden rise in earth potential of the distance relay panel due to wedging of

A/R contacts facilitated by the poor condition of the existing earth-mat (this issue was

elaborated in various reports as mentioned under Item No. B).

It may be noted that at the time of switching off of DC-supply, B-ph pole was in open

condition, and the other two phase poles (R & Y) of CB were in closed condition.

A.2.3 B-G fault in Ambewadi-Ponda line-2 at 20:57 hrs:

R

Y

B

Ambewadi Ponda

Now, in order to open the R & Y ph breaker limbs of Ponda-2, the operator had restored

the DC supply at around 20:57 hrs after removing the protection DC fuses in the panel to

avoid further damage.

Immediately, Closing-Pulse from the A/R got extended resulting in closing of B-ph pole.

However, as Close-contact of A/R was already in wedged-condition, this extension of

closing pulse could be attributed to momentary arc formation across the wedged close-

contacts of A/R.

Since DC protection fuses for the relays had already been removed, the back-up

protections at Ambewadi end could not operate during the incident; as a result the fault

was kept feeding from the other lines connected to Ambewadi from the remote ends.

The duration of fault feeding was observed to be around 5.2 sec.

A.3 Reasons for Delayed Fault Clearance:

It was noted that Ambewadi –Ponda (Xeldem) line-1 and 110 kV system were radially fed

from Ambewadi. Further, there was no generation at Supa HEP. Therefore, the only

available sources to feed the fault current were 220kV Ambewadi-Nagjhari and 220kV

Ambewadi- Narendra lines.

However, due to the low magnitude of the fault current involved (around 600 – 800 A),

the fault could not sensed by the remote end distance relays on Narendra and Nagjheri

bound lines. As such, fault was continued to be fed from all the four lines till the back-up

protection at respective ends came into action to trip the lines.

KPTCL informed that 220kV Narendra lines 1& 2 fed the fault for about 5 sec before finally

being tripped on DEF/DOC protection. The fault currents and dip in voltages were

observed to be very less . [However, it may be noted that in Narendra end DR furnished

for both the lines 1 & 2, time-scale was restricted to one second only. Also no EL was

furnished.]

As per DR & EL of Nagjhari line-1 end, the fault was observed to be fed for about 5sec.

In this regard, the Relay settings adopted for all lines connected to Ambewadi SS, and

Nagjheri – Ambewadi lines at Nagjhari PH, and Narendra-Ambewadi lines at Narendra SS

as provided by KPTCL are enclosed at Annexure-V.

B. Status Review of Renovation & Upgradation (R&U) works of Ambewadi SS

220/ 110 kV Ambewadi substation of KPTCL is an inter-regional substation located on the north-

western periphery of Karnataka. The criticality of the substation can be gauged from the fact

that not only does it form an important outlet for evacuation of power from 220 Nagjheri Ph,

but also constitutes the vital link in supplying power to the tune of (100 MW) to the state of Goa

located in the western region. Given its significance, the substation was audited by SRPC team

way back in 2012, which recommended certain actionable measures covering all protection

aspects including reviewing earthing of all equipments, for implementation. Similarly, there was

an internal-audit of the substation conducted by KPTCL in April, 2014 with regard to

strengthening of earth-mat (report enclosed at Annexure–III), which clearly spelt out the need

to go for replacement (for deteriorated conductors) / strengthening of the existing earth-mat

Minutes of the PSAG-16 Meeting held on 18.07.2016 at Ambewadi SS Page 4

immediately to avoid further failure of the equipments & interruptions of power supply to the

consumers. Then in April, 2015, a field visit of the substation was undertaken by CEA team to

ascertain the problems in the transmission lines feeding Goa from Karnataka in Southern Region,

which gave certain protection-specific recommendations to be implemented at Ambewadi SS to

improve export capacity of 220 kV Ambewadi-Ponda lines. (Compliance report of the same as

furnished by KPTCL is given at Annexure–IV). Apart from these, there were also

recommendations specific to Ambewadi SS given by the Protection Coordination Sub-Committee

(PCSC) of SRPC w.r.t. providing bus-bar protection, LBB protection, double-bus operation, and

auto-reclosure on all lines emanating from Ambewadi.

Keeping above in view, inspection of the switchyard and control room was carried out by the

PSAG team to get a first-hand view of the status of the R & U works of Ambewadi SS. The

major observations of the PSAG team were as follows:

Lush-green vegetation (grass) was observed in the entire yard.

Circuit breakers did not seem to be properly maintained and found rusted.

The faulty distance relay of Ponda-2 line was sent to manufacturer for repair, and was

replaced by a spare relay.

CVTs of Bus II had not been commissioned yet; only Bus I (Single bus) was in operation.

Bus-I CVT was being used for protection of all lines.

A/R was not provided for Narendra and Nagjheri bound lines. For Ponda-2 line, A/R,

though provided, was kept out of service after the above grid occurrence. As regards

Ponda-1 (Xeldem) line, KPTCL informed that A/R, which was already commissioned, would

be kept into service soon.

PLCC was available on all lines except Ponda and Xeldem lines. For double circuit line

inter-circuit coupling had been provided. However, only one channel had been provided

for both Protection and Speech.

Auxiliary AC supply change-over was being effected in manual mode.

For 220 V protection DC supply, only one charger was available for two battery sets and

the two battery sets were connected to the same DC load Bus. For 48 V communication

DC supply, only one battery set was available with one charger.

It was generally observed that works relating to complying with the protection audit

recommendations given by SRPC team in 2012 w.r.t. providing Bus bar and LBB

protections, GPS, DG set, Main-II line protection, Redundant DC supply, etc. are yet to

take-off.

When enquired about the same, KPTCL informed that works relating to implementing above

recommendations had been covered under the scope of Renovation & Upgradation (R&U)

works, whose contract was originally awarded to M/s Easun Reyrolle. However, as they could

not complete the works as per contractual agreement, their contract had been terminated, and

a fresh contract for the R&U works had now been awarded to M/s Alstom in December, 2015.

KPTCL also informed that the total contract for R&U works cover 23 stations of KPTCL including

Ambewadi, and M/s Alstom was conducting sub-station wise survey to finalize the purchase of

materials.

C. Recommendations:

Reasons for SOTF non-operation during the second fault to be investigated, and if

required, its settings shall be suitably revised for correct operation.

The settings of back-up protections (O/C & E/F relays) at Narendra and Nagjheri ends on

the Ambewadi – Narendra and Ambewadi – Nagjheri lines for a typical fault on 220 kV

lines emanating from Ambewadi shall be suitably revised so that they operate with

minimum possible time allowed by their respective I-t (current-time) characteristics. For

this, the use of IDMT characteristics may be explored to be in the fitness of the things.

To go for immediate replacement (for deteriorated conductors) / strengthening of the

existing earth-mat on war-footing basis to avoid further failure of the equipments &

interruptions of power supply to the consumers as brought out in the KPTCL report dated

19.04.2014.

The R&U works covering LBB protection, Busbar protection, GPS provisision, Main-II

protection to be completed without further delay in the time-lines stipulated by Hon’ble

CERC.

Both the buses (Bus I & Bus II) to be made operational with bus-coupler in service.

Auto-reclose feature to be provided for all 220 kV feeders emanating from Ambewadi SS.

Line CVT’s to be provided in all three phases for all 220 kV lines

Two sets of battery-banks and chargers to be provided for both protection (220 V) and

communication (48 V) applications.

Redundancy in PLCC communication to be provided by providing two channels for both

protection and speech for each circuit.

All breakers and substation equipment to be properly maintained. CB replacement works

may be undertaken wherever required.

Care to be taken to maintain proper upkeep of substation by regularly undertaking cutting

of weeds, grass & unwanted vegetation growth, esp. in the switchyard area.
