पररचय / Introduction
Important Grid Elements of North Eastern Regional Grid
Important Grid Elements of North Eastern Regional Grid has been issued in compliance with
IEGC 5.2 (c)
1. The criterion that has been adopted for including a transmission line in this list is as follows:
a) All 400 kV & 220 kV AC Transmission Lines
c) All 132 kV AC Transmission lines belonging to POWERGRID & Generating Stations
d) All 132 kV & 66 kV AC Transmission line from the territory of one State Control Area to
other State Control Areas (Tie Lines)
e) All 132 kV Lines affecting system security or forming part of Islanding Scheme or
reduction of generation
f) All Inter Regional Transmission Lines
g) All Trans National Transmission Lines
2. The transmission lines in the above context means a grid element from bus-bar to busbar and
includes all equipment such as associated circuit breakers, Line reactors, Isolators, CVT’s ,
CT’s etc.
3. The criteria that has been adopted for including a generating unit is as follows:
a) All Units owned by central & state sectors connected to the NER Grid
4. Outage or the intention to take under outage, of any major component/sub-system, which
would reduce security/ redundancy level of the above element, shall be precisely intimated to
NERLDC along with the likely time and status regarding revival.
5. Any 400 kV bus, 220 kV bus and 132 kV Main Bus shutdown at Sub-Stations needs the
approval of NERLDC.
6. In respect of 400 kV Sub-Station/ Power Station Switchyard having breaker and a half
switching scheme, outage within the substation (say main or tie circuit breaker) not affecting
power flow on any line/ICT can be availed by the constituents under intimation to NERLDC.
However, while availing such shutdowns or carrying out switching operations it must be
ensured by the substation that at least two Dias are complete even after such outage from the
view point of network reliability. Any outage not fulfilling the above condition needs the
approval of NERLDC.
7. Shutdown of any important bus-coupler bays needs prior approval of NERLDC. For example,
Bus coupler bay of 132 kV Gohpur substation of AEGCL.
8. Hot line maintenance of any lines among List of important elements of NER needs prior
approval from NERLDC.
7
9. For switching operation of any element under List of Important Grid Elements, Operating Code Number will be taken from NERLDC. Validity of
operation code number required for opening & closing of any element under List of Important Grid Elements will be 20 (twenty) minutes and beyond that
period fresh operation code number for switching operation of the element is to be obtained from NERLDC.
