SECTION 55ELECTRICITY (SUPPLY) ACT, 1948

AMENDED 1998

2) The Regional Load Despatch Centre shall give the apex body to ensure integrated operation of the power system in the concerned region.

3) The Regional Load Despatch Centre may give such directions and exercise such supervision and control as may be required for ensuring integrated grid operation and for achieving the maximum economy and efficiency in the operation of the power system in that state

oror - Outage of one pole of HVDC Bipole line, or- Outage of one pole of HVDC Bipole line, or - Outage of 765 kV S/C line.- Outage of 765 kV S/C line.

a ) All Regional constituents shall endeavor to

operate their respective power systems and

Power Stations in synchronism with each

other at all times, such that the entire system

within a Region operates as one synchronised

system.

IEGC-Chapter - 6 Clause - 6.2

System Security Aspects:

b) No part of the grid shall be deliberately isolated from the rest of the

Regional Grid, except

(I) under an emergency, and conditions in which such isolation would

prevent a total grid collapse and/or enable early restoration of power

supply

(II) when serious damage to a costly equipment is imminent and such

isolation would prevent it

(III) when such isolation is specifically instructed by RLDC. Complete

synchronisation of grid shall be restored as soon as the conditions again

permit it. The restoration process shall be supervised by RLDC, as per

operating procedures separately formulated.

IEGC-Chapter - 6 Clause - 6.2

System Security Aspects:

IEGC Chapter - 6 Clause - 6.2

C ) No important element of the Regional grid shall be

deliberately opened or removed from service at any time, except

when specifically instructed by RLDC or with specific and prior

clearance of RLDC. The list of such important grid elements on

which the above stipulations apply shall be prepared by the

RLDC in consultation with the constituents, and be available at

RLDC/SLDCs. In case of opening/ removal of any important

element of the grid under an emergency situation, the same shall

be communicated to RLDC at the earliest possible time after the

event.
