KSEBL Note on ITEM No. 3.11

North Trissur - Kozhikode - Mylatti 400kV line

The 400kV North Trissur (Madakkathara) – Kozhikode (Areakode) DC line was approved

in the 30th

meeting and Kozhikode (Areakode) – Mylatty - Mangalore (Udupi) DC line in

the 35th

meeting of Standing Committee on Power System Planning in Southern Region as

regional scheme under system strengthening.

In the 30th

standing committee, KSEB said that the North Trissur-Kozhikode 400 kV Quad

D/C line might be implemented with fresh RoW and in case PGCIL faces difficulty in

obtaining fresh RoW then KSEB would spare RoW of its Trissur-Kozhikode 220 kV S/C

line for constructing the North Trissur- Kozhikode 400 kV D/C line. . While taking up this

line for the construction of 400kV line, the supply to Malaparamba is to be ensured. Hence

the construction can be taken up as a multi circuit line part by part (towards south of

Malaparamba and north of Malaparamba in sequence ensuring feeding to Malaparamba on

220kV level). As soon as the Edamon – Kochi portion of the Tirunelveli – Kochi line is

completed and further with the commissioning of Pugalur – Madakkathara HVDC link and

Udupi – Areakode link, this line becomes a major tie line. As the construction is to be

carried out time bound using the RoW of the existing 220kV feeder, it is proposed that the

work may be carried out by KSEBL. PGCIL and other constituents agreed to the proposal.

As per the 35th

meeting of Standing Committee on Power System Planning in Southern

Region, Udupi – Kozhikode (Areakode) 400kV DC was approved, subject to the

observations of ESCOMs in Karnataka within a month. During the SRPC meeting on 12th

May 2015, it was clarified that the ESCOMs of Karnataka has not furnished any comments.

The matter was discussed in detail and the apprehension raised by Karnataka was regarding

the reduction of support at Hassan when the line is constructed, which may lead to

overloading in Hiriyur area. Though the system studies do not indicate any such issues, the

apprehension of Karnataka needs to be addressed. SRLDC has explained the necessity of

the UPCL Kozhikode link in the 26th

SRPC meeting from the reliability point of view.

Further, under the PoC regime transmission charges will be borne by the concerned utility

using the system. The North Trissur Kozhikode Mylatty link is also critical in relieving

congestion in S1 S2. After deliberations, KPTCL had informed that they have no objection

if the other lines to the south of Areakode and the HVDC link are in place before connecting

Udupi to Areakode. However, KSEBL is facing severe transmission constraints in the

Northern Kerala. The supply to Northern Kerala from Areakode is dependent on the 220kV

Annexure-IX

(Page1 of 2)

Areakode – Mylatty double circuit, which is LILOed at Orkattery (Vadakara), Kanhirode

and Taliparamba. Even now, during high demand period, there is no (N-1) security to the

north of Areakode even if the Mysore – Areakode 400kV line is commissioned. The issue is

regularly flagged by SRLDC and NLDC in their reports also. Hence, the line upto Mylatty

and the 400/220kV substation at Mylatty are to be completed as early as possible. The

interconnection of Udupi to Mylatty can be scheduled to match with the commissioning of

HVDC link at Madakkathara.

Obtaining a fresh RoW from Areakode to Mylatty is not easy in most of the stretches upto

Mylatty. From Mylatty, upto the Kerala border towards Udupi, fresh RoW is possible.

Further, considering the load growth of Northern Kerala, which is more than that of

Southern Kerala, many of the 110kV lines in this region needs to be upgraded. As on date,

doubling of some of the 110kV lines is in progress. Upgradation of some of the 110kV lines

to 220kV is being investigated for possible route of minimum issues on RoW. The

construction of the 400kV double circuit from Areakode to Mylatty, as part of system

strengthening approved in the 35th

Standing committee meeting, can be considered using the

RoW of existing 220kV DC provided the 220kV line is also accommodated as multi circuit.

Here also the construction has to be in steps of each stretch so that the feeding to the

existing 220kV substations is not affected. In view of the above, construction of this part of

the line will be convenient if executed by KSEB. It is apprehended that if this part of the

line is given on TBCB route, severe RoW issues may crop up resulting in the fate similar to

that of Edamon – Kochi stretch, Bangalore – Dharmapuri stretch, Yelahanka area, Mysore –

Kutta area etc. Udupi – Myaltty portion can be taken up to match with the completion of

HVDC link at Madakkathara. Since the line length is very small (about 100-120km), this

portion may be handed over to PGCIL for execution.

ROP in Petition No. MP/420/2014 Page 1 of 3

CENTRAL ELECTRICITY REGULATORY COMMISSION NEW DELHI

Petition No. 420/MP/2014 Subject : Endangering grid security due to non-implementation of

contingency demand disconnection scheme for sudden loss of wind generation as per CERC order dated 22.2.2014 in Petition No. 120/MP/2011, non-availability of LVRT protection, non scheduling of wind generation as per Regulation 6.5.23 (j) of the Central Electricity Regulatory Commission (Indian Electricity Grid Code) Regulations, 2010, Regulation 5.3 regarding lack of necessary demand estimation and not providing real time SCADA data to LDC.

Date of hearing : 26.2.2015

Coram : Shri Gireesh B. Pradhan, Chairperson Shri A.K. Singhal, Member Shri A.S. Bakshi, Member Petitioner : Southern Regional Load Despatch Centre Respondents : Tamil Nadu State Load Despatch Centre

Parties present : Shri V. Suresh, SRLDC Shri Pankaj Batra, CEA Shri S. Vallinayagam, Advocate, SLDC, Tamilnadu Shri S.K.Sonee, POSOCO Record of Proceedings

The representative of Southern Regional Load Despatch Centre (SRLDC) submitted as under:

(a) Regulation B (3) of the Central Electricity Authority (Technical Standards for Connectivity to the Grid) Regulations, 2007 provides that Low Voltage Ride Through (LVRT) is compulsory for machines installed after 15.4.2014 but for existing wind power generating stations, LVRT should be mutually discussed. It does not exempt any station from installing LVRT.

(b) The issue of installing LVRT has been discussed from the time when the installed capacity of wind in Sothern Regioin was 3000 MW.

______________________________________________________________________________

ROP in Petition No. MP/420/2014 Page 2 of 3

Presently, the installed capacity is around 13,000 MW. Out of this, 9000 MW wind capacity does not have LVRT.

(c) No tangible action has been taken with regard to installation of LVRT. The responsibility of monitoring installation LVRT has not been fixed under any Regulation.

2. The representative of CEA submitted as under:

(a) At the time of framing Central Electricity Authority (Technical Standards for Connectivity to the Grid) Regulations, 2007, it was thought that installation of LVRT on existing machines will have an implication on tariff. Since, ADMS scheme has not been implemented by the States, the grid becomes vulnerable due to emergency situations such as sudden variation of load/loss of wind generation or forced outages are there etc. Therefore, availability of LVRT is very important.

(b) STU/SLDC should be responsible to monitor installation of LVRT. LVRT should fall under the Connectivity Regulations of respective State.

3. In response to the Commission’s query regarding availability of LVRT on new generators, the representative of CEA submitted that status of LVRT on new generators will be filed after checking with generators.

4. The representative of POSOCO submitted that installation of LVRT needs to be ensured at the time of “connection” of the wind generators itself. The strictness of LVRT is necessary.

5. After hearing the parties, the Commission directed to admit the petition and issue notice to the respondents. The Commission directed to issue notice to Wind Energy Association and Solar Power Association of Southern Region. 6. The Commission directed the petitioner to implead Wind Energy Association and Solar Power Association of Southern Region as party to the petition and file revised memo of parties. 7. The Commission directed the petitioner to serve copy of the petition on the respondents, Wind Energy Association and Solar Power Association of Southern Region immediately. The respondents were directed to file their replies by 27.3.2015 with an advance copy to the petitioner, who may file its rejoinder, if any, on or before17.4.2015.

______________________________________________________________________________

ROP in Petition No. MP/420/2014 Page 3 of 3

8. The Commission directed the respondents to submit on affidavit by 27.3.2015 status of LVRTs on wind generators in their respective States. 9. The petition shall be listed for hearing on 23.4.2015.

Annexure –XVII (SRTS-II- PPT on AMR)

<12 Pages>

POPULATION OF SEMS

• NO OF SEMS > 900 (EXPECTED TO INCREASE BEYOND 1000 IN ONE YEAR)

• NO OF LOCATIONS > 150

• NO OF MAKES: AT PRESENT AROUND 4 MAKES (SML, L&T, WALLABY, ELSTER) OF METERS OF DIFFERENT

SERIES ARE INSTALLED AT DIFFERENT LOCATIONS OF SR

CURRENT METHOD OF RELAY OF DATA TO RLDC

• DATA FROM EACH METER IS DOWNLOADED IN TO A HAND HELD DEVICE (DCD) THROUGH THE OPTICAL

PORT

• THE DATA IS FURTHER DOWNLOADED ON TO THE LOCAL PC USING MANUFACTURER PROPRIETARY

SOFTWARE.

• THIS DATA IS THEN TRANSMITTED TO SRLDC AS EMAIL ATTACHMENT

• SRPC APPROVED IMPLEMENTATION OF THE AMR SCHEME BY POWERGRID IN THE 24TH MEETING HELD ON

15-03-2014 AT CHENNAI.

• IT WAS ALSO AGREED THAT POWERGRID COULD FIRM UP APPROPRIATE TECHNOLOGY FOR

IMPLEMENTATION, BASED ON THE EXPERIENCE IN OTHER REGIONS/UTILITIES

• ACCORDINGLY THE SYSTEMS BEING IMPLEMENTED IN NORTHERN REGION AND EASTERN REGION WERE

STUDIED

• ALSO NECESSARY INPUTS AND FEEDBACK WAS TAKEN FROM THE IMPLEMENTING AGENCIES (M/S

KALKITECH & M/S TCS)

PROPOSED AMR IN SR

• THE AMR PROPOSED FOR SR IS ALSO ON THE SIMILAR LINES OF THE SCHEME THAT IS IMPLEMENTED IN NR

& ER WITH FEW MODIFICATIONS

• THE MAJOR ENHANCEMENT SOUGHT IN THE SCHEME IS TO HAVE A BETTER COMMUNICATION CHANNEL

MAJOR COMPONENTS OF AMR

• DATA CONCENTRATOR UNIT (DCU) – TO BE INSTALLED AT EACH LOCATION

• COMMUNICATION CHANNEL

• CENTRAL DATA COLLECTION SYSTEM – TO BE ESTABLISHED AT RLDC

PROPOSED HIRARCHY OF AMR IN SR

ARCHITECTURE OF

THE PROPOSED AMR

SCHEME IN SR

AMR IN SR

• ESTIMATED COST OF IMPLEMENTATION IS AROUND RS. 4.0-4.5 CRORE

• SYSTEM TO COVER AMC OF 4 YEARS AFTER THE EXPIRY OF WARRANTY OF ONE YEAR

• MAJOR ENDEAVOUR IS TO USE THE BANDWIDTH FROM THE EXISTING FIBER OPTIC NETWORK WHEREVER

POSSIBLE

• EXISTING BROADBAND CONNECTIVITY, IF AVAILABLE, TO INTERNET CAN ALSO BE USED FOR AMR

• GPRS WILL BE THE LAST OPTION WHERE BOTH FIBER/BROADBAND IS NOT AVAILABLE

AMR IN SR

• AS AGREED IN THE 24TH SRPC MEETING, COORDINATION, OPERATION & MAINTENANCE SUBSEQUENTLY

AFTER THE INSTALLATION OF AMR INFRASTRUCTURE TO BE LOOKED AFTER BY THE RESPECTIVE UTILITY

• RECURRING COMMUNICATIONS EXPENDITURE, IF ANY (GPRS CHARGES) ARE TO BE BORNE BY THE OWNER

OF PREMISES WHERE THE INFRASTRUCTURE IS INSTALLED.

AMR IN SR

• DETAILED TECHNICAL SPECS AND SCOPE AND EXECUTION GUIDELINES ALONG WITH THE ESTIMATE ARE

UNDER PREPARATION AND SAME SHALL BE FORWARDED TO BENIFICIARIES AND SRLDC.

• AFTER THE RECEPT OF CONCURRENCE OF STAKEHOLEDERS, NECESSARY ACTION FOR TENDERING AND

AWARD SHALL BE TAKEN UP.

COOPERATION FROM ALL THE STAKEHOLDERS IS HIGHLY SOLICITED
