Subject: Co-Generation test on Nov 21, 1995
We have scheduled the following tests to be performed starting at mid-night
Tuesday November 21, 1995 and being completed no later than 6am on
Wednesday November 22, 1995
1. Test the system response to opening the electrical ties to
Cambridge Electric when there is a zero(0) net interchange
of power between MIT and Cambridge Electric.
2. Test the system response to opening the electrical ties to
Cambridge Electri when there is a net EXPORT of power from MIT
to Cambridge Electric.
3. Simulate the system response to opening the tie to Cambridge
Electric when there is a net IMPORT of power from Cambridge
Electric to MIT.
During this "load shed" verification, we will have our S&C
motorized disconnect switch operators in a "test" position, so
that the control circuits can be verified as functional without
actually tripping off any load.
WE WILL NOT ACTUALLY LOAD SHED - THIS WILL BE A SIMULATION ONLY.
If you have critical work/equipment, please make any
arrangements ( including backing up work) that are needed to
deal
with a slim risk of an outage.
While performing these tests, we will also verify the operation of the
under-frequency relay used to initiate load shed trip signals
when MIT is at a peak electrical generation level and there is a
loss of power from the Cambridge Electric Company.
Following the successful completion of these tests, MIT can be assured of
the gas turbine's capacity to maintain stable power with the major loss
of
supplemental power from Cambridge Electric.
These tests are best performed when we are operating close to normal
conditions. This means that we will need both MIT community , as well
as Cambridge Electric Company support during the test period to
secure critical equipment, and provide synchronizing signals.
The duration of the tests is expected to be a maximum of 4 hours, but we
are scheduling a six (6) hour time frame to provide a maximum test
envelope.
Thank you for your continued support.
