Additional Agenda notes for the 39th Meeting of Standing Committee on Power
System Planning in Western Region
1.0
Provision of 4nos of 220kV feeder bays at 750MW Rewa Ultra Mega Solar
Project (UMSP) Pooling Station – proposal by MSETCL.
1.1
Rewa Ultra Mega Solar Project (UMSP) of 750MW capacity to be constructed in
Gurh tehsil of Rewa district has already been approved by MNRE. Rewa UMSP is a
joint venture company of MP Urja Vikas Nigam Ltd (MPUVNL) and Solar Energy
Corporation of India (SECI). The following transmission system for Rewa Ultra Mega
Solar Project (RUMSP) has been agreed in the 38th SCM of WR :
1.2
a.
LILO of Vindhyachal – Jabalpur 400kV 2nd D/c line (circuit-3&4) at Rewa
Pooling Station – 59KM (2x27=54KM D/c portion + 5KM M/s portion)
b.
Establishment of 400/220kV, 3x500 MVA Pooling station at Rewa
c.
1x125 MVAr bus reactor at Rewa Pooling Station
d.
6 Nos. 220kV Line bays at Rewa Pooling station (for its interconnection with
solar park)
MPPTCL Vide letter 04 – 02/PSP – 421/2988 dated 20.11.2015 has informed that
400/220kV Satna (PGCIL) S/s is feeding power to Rewa, Satna, Sidhi and
Chhatarpur areas. The above substation is critically loaded and outage of any
element would result in loss of supply in the above areas. 400/220kV substation at
Rewa which has been proposed as a part of the evacuation system for 750MW
RUMSP (solar power which is available around 8hrs during the day time only) would
be utilized for 8hrs only and for remaining period of about 16hours the proposed
pooling station remains unutilized.For better utilization of proposed 400/220kV Rewa
pooling station and to relive loading on 400/220kV transformers at Satna (PGCIL),
MPPTCL has proposed the following transmission system:
1.3
220kV D/C line from 400/220kV Rewa Solar Pooling Station to Rewa 220kV
S/s.
220kV D/C line from 400/220kV Rewa Solar Pooling Station to Sidhi 220kV
S/s.
For termination of aforesaid 220kV lines, MPPTCL has requested for provision of
4nos of 220kV feeder bays at the proposed 400/220kV Rewa pooling station and
MPPTCL would also bear the cost of these 4nos of 220kV feeders if agreed by
PGCIL.
Members may deliberate.
2.0
Standardization of OPGW in lieu of One Earth Wire in all Transmission lines –
agenda by POWERGRID
2.1
The Power System requirement for Communication is increasing multifold due to
a. special protection scheme
39th SCMPSPWR Additional Agenda

b.
c.
d.
e.
Ever increasing data reporting to Load Dispatch Centre.
Phasor measurements based data collection and reporting.
Remote monitoring/operation of sub-station/elements.
Differential protection on Lines
The present practice of putting fiber in select lines for a stations connectivity lead
to situation where stations connectivity is held up whenever the identified OPGW
implementation held up either due to line delay, rerouting or LILO of under
construction line for example connectivity of Siratu 132 KV.
2.2
OPGW installation on existing lines is taking long time / delayed due to shut down,
ROW issues as well as capacity constraints of executing agencies.
2.3
It is proposed to include one 24 Fiber (OPGW) in all transmission lines which will
ensure availability of wideband Communication from all substations to cater
bandwidth for various power system application for which communication equipment
(SDH– STM-16) shall be provided at all upcoming substations.
2.4
POWERGRID may present the case and members may deliberate.
3.0
Provision of 2 nos of 220kV bays at Raipur (PG) substation for LILO of
Khedamara (CSPTCL) – Borjhara S/c line at 220kV Raipur (PG) substation.
3.1
In 38th Meeting of Standing Committee on Power System Planning in Western
Region held on 17.07.2015, construction of 2 nos. 220kV line bays by POWERGRID
at its Raipur 400/220kV substation was agreed for termination of LILO of Khedamara
(CSPTCL) – Borjhara S/c line of CSPTCL.
3.2
2 nos. 220kV line bays were constructed along with installation of additional 315
MVA, 400/220 kV ICT at Raipur 400/220kV substation as part of WRSS-6 (approved
in the 25th Meeting of Standing Committee on Power System Planning in Western
Region held on 30-09-2006). It is understood that CSPTCL has earmarked these
2no of 220kV line bays at Raipur for termination of 220kV D/c line from DOMA.
However, these 220kV line bays are still unutilized.
3.3
POWERGRID has requested CSPTCL to confirm whether these 2 nos. 220 kV line
bays shall be utilized by them for termination of 220 kV D/c line from DOMA
(CSPTCL) or the same can be utilized for LILO of Khedamara (CSPTCL) - Borjhara
220 kV S/c line.
CSPTCL may confirm regarding utilization of the 220 kV bays.

4.1
Augmentation of Transformation Capacity at ISTS substations in WR to meet
n-1 contingency of transformer- agenda by POWERGRID
It has been observed that at many ISTS substations, n-1 transmission planning
criteria doesn’t get fulfilled in case of transformer outage. Sometimes it leads to load
restriction during peak demand to avoid overloading of transformers. List of such
substations along with recorded peak loadings is given in the table below. Further,
load flow studies have been carried out to assess the extent of loading on these

Measure to control Fault Level at pooling stations/ substations in Chhattisgarh
area
5.1
A large number of generation projects are coming up in Chhattisgarh which are
getting pooled at various substations (at 765kV level) for onward transfer of power to
other parts of the grid. This is leading to very high short circuit levels at almost all
pooling stations of Chhattisgarh viz. Raigarh (Kotra) Pool (400kV & 765kV), Raigarh
(Tamnar) Pool (400kV & 765kV), Champa Pool (400kV & 765kV), Dharamjaygarh
Pool (400kV & 765kV), Bilaspur Pool (400kV & 765kV) and Raipur Pool (400kV &
765kV). Studies have been carried out to suggest suitable measures so as to control
the fault levels of the substations in Chhattisgarh area within design values. The
issue was discussed in the last Standing Committee Meeting (SCM) wherein it was
decided that joint studies shall be done by CEA and CTU and the issue shall be
finalized in the next WR SCM.
5.2
Joint study results indicate that following measures need to be taken to control the
fault levels of the substations in the Chhattisgarh area:
a. To improve the reliability of power transfer from generating stations connected at
Raigarh Pool (Tamnar), LILO of both ckts of Jharsuguda – Dharamjaygarh765kV
1x D/c line at Raigarh (Tamnar) Pool was agreed in 36th SCM of Western Region
held on 29.08.2013.
In 17th SCM of ER held on 25.05.2015, ERPC stated that Jharsuguda –
Dharmajaygarh 765kV lines were planned for evacuation of power from Odisha
IPPs and Surplus generation in ER to WR & NR. It was also envisaged that LILO
of above line at Raigarh (Tamnar) Pool may restrict power evacuation from ER
side and would create congestion, thereby overloading in Eastern regional
networks. Also, the concerns were raised by ER constituents regarding rising
values of fault level at Jharsuguda and nearby substations after LILO of above
line at Raigarh (Tamnar) Pool. The case was studied and found that with the
proposed LILO line, fault level of a number of substations incl. Dharamjaygarh
Pool, Raigarh (Tamnar) Pool and Jharsuguda, is becoming very high. In view of
the above, it is proposed to withdraw the LILO of Jharsuguda – Dharamjaygarh
765kV D/c line at Raigarh (Tamnar) Pool. Further, in order to ensure reliable
39th SCMPSPWR – Additional Agenda
4
evacuation of power for generation projects getting pooled at Raigarh (Tamnar)
Pool, following is proposed.
Raigarh Pool (Tamnar) Pool – Dharamjaygarh 765 kV D/c Line.
b. In order to contain the fault level within designed value Champa Pool, proposal
for Series Reactors and BUS Split arrangement was discussed in the 37th WR
SCM held on 05.09.2014. After comprehensive studies, it has been observed that
fault levels at Champa Pool may be contained with Bus splitting arrangement at
both 765kV & 400kV levels even without series reactors.
c. Further, in the 30th WR SCM held on 08.07.2010, it was decided to keep following
circuits in normally open condition at a later date:
Raigarh Pool (Kotra) – Raigarh (Existing) 400 kV D/c line.
Raipur Pool– Raipur (Existing) 400kV D/c line.
These lines may be kept normally open and may be used depending on the
system condition
d. Splitting of 765kV Dharamjaygarh S/s and both 765kV & 400kV buses of Raigarh
Pool (Kotra) S/s.
e. During the studies, it was observed that the interconnection between 4x600MW
TPP and 4x250MW TPP of M/S Jindal Power Ltd, when switched ON, contributes
excessive fault current to Raigarh (Tamnar) Pool & Raipur Substations. Hence,
the same has been switched OFF in the studies. The same shall have to be
ensured by M/s Jindal Power Ltd.

Measure to control fault level at Wardha Substation
6.1
Fault levels at several substations in Chhattisgarh area were brought under control
through suitable splitting arrangements as discussed at item no. 5 without the need
39th SCMPSPWR – Additional Agenda

of installation of series reactors. Even after splitting the above buses in Chhattisgarh,
fault level at Wardha Substation remains very high. It was observed that short circuit
level of 765kV Wardha bus reaches about 46 kA and that at 400kV bus reaches
about 78 kA in 2018-19 condition.
The single line diagram of Wardha substation is given below:

At 400kV Wardha bus, major fault current contributories are –
6.2
Warora Pool D/c line – 16kA
Warora (MSETCL) S/c line – 7.7kA
Koradi II (MSETCL) S/c line – 9.6kA
Mauda TPP D/c line – 5.6kA
765/400kV ICTs – 26kA
It is clear that Warora Pool contributes the most at Wardha 400kV bus. In view of the
above, the option of bypassing Mauda TPP – Wardha 400kV D/c line at Wardha bus
and connecting it with Wardha – Warora Pool 400kV D/c (Quad) line so as to form
Mauda TPP – Warora Pool 400kV D/c (Quad) line was explored. Further, it is
observed that the interconnection with MSETCL system contributes about 17.6kA at
400kV Wardha bus. Further, addition of 3x660MW generation at Koradi TPP II would
exaggerate the problem. From power flow point of view, these interconnections are
not very significant after development of state transmission system from Koradi TPP
II. In view of above, the following re-arrangement is proposed at Wardha Substation:
(i)
Bypassing Mauda TPP – Wardha 400kV D/c line at Wardha bus and connecting
it with Wardha – Warora Pool 400kV D/c (Quad) line so as to form Mauda TPP

It may be noted here that design rating of Wardha substation is 40kA (3 phase) for
both 400kV and 765kV levels. With the proposed re-arrangement, fault levels
reduced from 78kA to 44kA at 400kV level and from 46 to 40kA at 765kV level.
Additional measures to contain the fault levels below 40kA needs to be further
worked out.
Members may deliberate.

Measures to control High fault levels observed in Vindhyachal complex
7.1
Fault levels in Vindhyachal complex have reached beyond the design limits. As
reported by WRTS II, in a fault on Vindhyachal - Korba 400kV line#2 on 11.10.15 at
a distance of 0.3km from Vindhyachal STPS, fault current fed from Vindhyachal was
around 47.4kA. There was a similar fault on the same line on 06.10.14 and the fault
current that was fed from Vindhyachal STPS was around 40kA. Such high fault
currents are detrimental to switchyard equipment’s. Failures of CT connectors,
isolator contacts, etc have already been reported during such faults.
7.2
Short circuit studies indicate following fault levels at Vindhyachal Complex:

From the above table, it is evident that all the substations in Vindhyachal complex
incl. Vindhyachal STPS and Sasan UMPP are exposed to very high fault currents.
Here, it may be noted that following was agreed in previous standing committee
meetings of Western Region:
1. LILO of Vindhyachal STPS – Jabalpur 400kV S/c line at Sasan UMPP has been
agreed to be delinked at Sasan UMPP in order to reduce SC levels in Sasan
UMPP and Vindhyachal STPS (agreed in 29th WR SCM held on 10.09.2009)
2. Vindhyachal STPS I,II, III – Vindhyachal STPS IV,V interconnection was agreed
as an interim arrangement till the commissioning of Vindhyachal STPS IV
Transmission System (agreed in the 33rd WR SCM held on 21.10.2011)
7.3
After considering the above agreed schemes in short circuit studies, fault levels are
seen to reduce considerably. The revised fault currents are tabulated below:

Since, Vindhyachal STPS IV Transmission system has already been commissioned,
the 400kV interconnection between Vindhyachal STPS I, II, III and Vindhyachal IV, V
of NTPC Ltd shall have to be opened.
Accordingly, Sasan Power Ltd. and NTPC Ltd. may update the status of opening of
the following elements in their respective switchyards:
1. LILO of one ckt of Vindhyachal STPS – Jabalpur 400kV D/c line at Sasan UMPP.
2. Vindhyachal STPS I,II,III – Vindhyachal STPS IV,V 400kV interconnection
Members may deliberate.
