Excitation System & capability curve of synchronous generatorMANOJ KUMAR MAHARANA
Excitation systems perform control and protective functions essential to the satisfactory performance of the power system.
The amount of continuous reactive power a generator can supply is restricted by various limits. In the over-excitation region limits are imposed by rotor heating or amount of field current and second is the stator current. In the under excitation region the limits are imposed by load angle. So in steady state the generator should always operate within this region and the loci of the various limiters are called the capability curve of the generator.

In just a few short years from now
the UK demand for electricity will be
uncomfortably close to the combined
generating power of both home and
imported power. There has been
significant investment in renewables
and wind in particular for the ‘green’
imperative and this has improved
where in 2017 a reported 52% of
demand was supplied from
renewable sources.
Some renewable sources are more
reliable than others and
furthermore, the gas and coal power
stations are being decommissioned to
align with emissions legislations from
Brussels, and any nuclear alternatives
will take years to come on line.
Consequently, there is an
understandable requirement for
embedded or distributed power
generation sources to secure supplies
and to export (Either partly, wholly,
or as part of a smart supply) to keep
the country running through all power
cycles. All of this means that relatively
small generators, diesel or gas;
reciprocating or turbine, are connected
to the grid and are increasing in their
percentage contribution.
The grid, as we know it now, is
fixed in volts and frequency and fairly
immovable. The grid of the future with
increasing wind power input and lighter
generators (say 30kW to 5mW) will
be less so and subjected to volts and
frequency excursions exceeding what
we see now.

This document describes an intermediate frequency induction melting cooker technology that uses two electric cooker bodies powered by a single intermediate frequency electrical source. The system includes electric cookers rated at 5-6 tons capacity that can reach 1750°C, a 3500KVA transformer that reduces voltage from 10KV to 750V, and an intermediate frequency electrical source rated at 3000KW and 250Hz. The scheme allows one cooker to melt material while the other remains on standby.
Power factor is the ratio of active power to apparent power. Low power factors are caused by inductive loads and non-linear loads which result in inefficient energy use and overloading of electrical equipment. Automatic power factor correction (APFC) systems automatically switch capacitor banks to maintain a target power factor under varying loads without manual intervention. Proper selection of capacitors, switching equipment, and harmonic filters is required when implementing APFC to prevent overloading and resonance issues.

ERPC, KOLKATA 2
3. Prior to DSM regulation, CERC(UI Charges and Related matters)
Regulation’2009 was in place.
In the mean time Two Major Grid disturbance occurred back to back
on 30th July’2012 and 31st July’2012 with blackout of NR, ER & NER
regions of India.
Load of around 48000 MW affected by the grid disturbance.
Largest power outage in the history by number of people affected.
GoI appointed a Enquiry committee under the chairmanship of
chairman CEA to study the cause of failure and submit report within
15 days.
ERPC, KOLKATA 3
4. Committee submitted its report on 16.08.2012 to GoI with causes of
failures and suggestions to prevent future grid failures.
Reasons for failure:
Weak inter regional corridor due to multiple outage.
Huge over drawl by NR utilities(UP, Haryana, Rajasthan & Punjab
etc.) and huge under drawl by WR utilities(MP, Maharashtra, Gujrat
etc..)
Inadequate response by SLDCs to the instructions of RLDCs.
ERPC, KOLKATA 4
5. Suggestions:
Frequency band needs to be further tightened close to 50 Hz.
A review of UI mechanism should be carried out in view of its impact on
recent grid disturbances.
Frequency control through UI may be phased out in a time bound manner.
Generation reserves/Ancillary services may be used for frequency control.
POSOCO file a petition before CERC for review of UI mechanism while
considering Enquiry Committee suggestions. After detail examination of the
proposal by staffs of commission, CERC issued draft CERC(DSM & Related
matters) regulation’2013 for public and same was implemented w.e.f.
17.02.2014.
ERPC, KOLKATA 5
7. Came into force on 17.02.2014
To maintain grid discipline and grid security.
Major provisions:
• Frequency band (50.05-49.85 Hz)
• ACP linked Deviation Rate Vector.
• Volume limit for buyer/seller.
• Cap Rate for all Generators.
• Addl. DC for sustained unidirectional deviation.
ERPC, KOLKATA 7
8. Frequency band is 50.05 Hz to 49.85 Hz.
Charges for deviation for each 0.01 Hz step is changing everyday.
Deviation price vector linked to Daily Average Area Clearing
Price(ACP) in Day Ahead Market of Power Exchange.
Charges for deviation below 49.85 Hz is fixed at 800p/u, for freq
50.05 Hz and above charges for deviation is 0 p/u.
Charges for deviation at 50.00 Hz will be Daily Average Area
Clearing Price(ACP) discovered at DAM (Max ceiling being 800 p/u).
The Day-ahead market price of the Power Exchange having a
market share of 80% or more in energy terms on a daily basis shall
be taken into consideration for linking to the DSM price vector.
DSM rate vector will have a dynamic slope determined by joining
the identified price points at 50 Hz(daily avg. ACP),frequency below
49.85 (800p/u) and 50.05 Hz (0p/u) on daily basis.
