RecordNotesoftheSubGroup(Wind) PCSCMeetingheldon08.07.2014 Page8

Enercon and Gamesa Make WEGs, Grid Monitoring System (Multi Function

Relay) is available in the above 3 WEGs. Out of the installed capacity of

7344.905 MW, the capacity with LVRT sensing and tripping (delay and

immediate) was 4,345 MW. For balance capacity of 2,999.905 MW of various

other make WEGs, LVRT setting or sensing is not available. Letter dated 11th

July.2013 of C-WET regarding LVRT provisions is also enclosed as Annexure-IV.

After the Meeting on 7th June 2013, the issue regarding provision of LVRT

features had been taken up with the NCES/Wind Developers.

KPTCL

The machines were not having LVRT features. There were no reported

incidents of wind generation pulling out even up to 400- 450 ms. ( Z2 fault )

provided grid support was available. It had been reported that the units were

pulling out in case grid support was lost on account of any reason.

It has been reported by wind developers that the cost impact of providing

LVRT features was around Rs.50-60 lakh per MW . There was some

apprehension regarding recovery of this cost since tariff had already been

finalized by the SERC.

Recommendations

Report on action taken /status on the recommendations of the Special

Meeting (Wind) held on 07th June 2013 to be communicated by TN (Annexure-

V).

Incidents of pulling out of wind generation to be analyzed by NCES,

TANGEDCO/TANTRANSCO/TN SLDC in consultation with Wind


Developers/OEMs to find the root cause with regard to units which had pulled

out and also which remained on grid. Settings adopted in the units was

needed to be studied and recommended settings communicated to all the

WEGs for necessary implementation. Summarized report in this regard to be

kindly submitted to SRLDC/SRPC by 21st July.2014 (before ensuing TCC/SRPC

Meetings). This should include status of availability of LVRT features, settings

adopted, whether settings adopted are meeting technical regulatory

requirements.

Since this is impacting grid security, the STU/SLDC to approach SERC for

ensuring LVRT feature on the existing machines. Action taken in this regard to

be submitted to SRLDC/SRPC by 21s t July 2014 (before TCC/SRPC Meetings).

It needed to be ensured that new units being commissioned are meeting CEA

(Technical Standards to the Connectivity to the Grid) Regulations 2007 and

Amendment Regulation 2013.

Data Acquisition System/Real Time Data Availability to SLDCs/SRLDC as

envisaged in IEGC needed to be ensured by the WEGs. States to take

appropriate action in this regard.

TN to study line loading/voltage profile in wind intensive area (Udumalpet,

Thirunelveli, etc.) and initiate appropriate action for generation backing

down/load management as per grid requirement. Action plan needed to be

implemented in the field is required to be finalized and communicated to the

field within a month.

TN to expedite the wind evacuation system which is under execution.


Dynamic reactive power compensation i.e. SVC/ STATCOM requirements at
