Any two or more systems that has parameter(such as
frequence,phase etc.) transfer function of time dependance,
when coupled to achieve output or input simultaneously
called synchronisation contrary to same phenomena when
parameters have no time dependance called paralleling.
Synchronization (in the context of electrical engineering)
is the process of attaining exact co-ordination(Relative
should be zero) between two or more, similar time varying
quantitites.The quantities involved must has same rate of
change.Synchronization is a global concept(exists through
out the system).
Paralleling is the process of placing more than one systems
aganist same condition to achieve common goal.In some cases
(parallel operation of alternators,parallel operation of
transformers etc.)synchronizion is must for paralleling
where as in some cases(Paralleling loads across a supply
etc.) in is not must for loads to be synchronized.
Paralleling is a local concept(Prevaling at few places and
these places are independent with each other)
synchronization means conecting the machinecs (Generators.
Transformers etc.,)with the existing large network(
grid ).parallel means concting the machinecs (Generators.
Transformers etc.,)with another machines in a small network.
Synchronization is the process of connecting alternator to
the grid system or aiternators which are already connected
after it is syncronised to the grid system then it is said
to be working parrlel with another alternators
Parallel:- in this process you dont have concentrate on
equality of Voltage, freq & phase angle. its a simple
method of devidation, so its easly to devide load on one or
Synchronisation:- in this process you have must be
conentrate on above parameters because its become direct
affect on source. it can be happen one or more equipments.
which should be done before loading the m/cs.
Transmission line design. Say, I have a 1MVA generator and
2 transformers that will have the same load. What would be
the proper rating of the trasformers? Is it safe to say,
that I will simply divide the total rating of the generator?
