why generation of syncronized generator increases when
frequency of grid is less then 50Hz & generation decreases
when grid frequency goes up from 50 Hz, as comparision with
set value entered in govering panel?

Answer Posted / vasanth

The Line Frequency is influenced by the Grid as that is
Infinite source. Since it is in Synchronized Pattern the
generator is influenced by the GRID. Due to the effect of
speed control Governor in the generator which fails to hold
the speed on its own due to other source which is
influencing, raises the fuel flow ,Flex raises and generator
take the additional load from the Grid. This is How the Load
is distributed across the sources .

A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
