Punjab Islanding Scheme - Northern Regional Power Committee

6.3 Network & Simulation Studies.
To assess stability and re-validate the formation of proposed islands under
different scenario, Dynamic network simulation studies and stability analysis
would be required beforehand. The study would analyze degree of swings in
the bus voltages, line flows and relative rotor angles, etc. The studies would
also suggest any additional measures to be taken for enhancing success rate
of islanding. Line network diagram of system showing boundary of islands is
given as Annexure VI.
6.4 Regular preventive Maintenance.
In order to ensure reliability of the island, regular preventive maintenance of
control switchgears, relays & protection system and governors at each of the
generating units, as covered in the scheme, shall be carried out by the
respective agencies.
6.5 Additional Requirements:
Any additional provision to meet with the functional requirements of the
Scheme shall be incorporated during implementation stage.
6.6 Periodic Review of islanding scheme.
The islanding scheme shall be reviewed periodically, at least once a year, by
the SLDC in consultation with the utilities. Changes in system topology,
loading conditions, generation/demand growth, etc shall be reviewed and
necessary changes in the islanding scheme shall be made accordingly.
6.6 Training and mock drills
The detailed procedures/instructions shall be developed and training shall be
imparted to the System Operators at SLDC and other personnel involved at
the sub stations and generating stations. A detailed mock drills shall be
conducted regularly, at least once in a year. SLDC shall co-ordinate this
activity with the utilities.
