REQUIREMENTS OR PARALLELING D.C. GENERATORS
The following are the principal types of situations where paralleling of D.C. generators is required
Paralleing shunt generators of the same or varying sizes.
Paralleling compound generators of the same or varying sizes.
There are certain requirements that must be met for successful electrical paralleling in all different situations. A parallel circuit is defined as one in which the same voltage exists across each unit as the paralleling point.
This is absolutely required by Kirchhoff s voltage law.
The following three conditions may be met if the generated voltages of the individual generators are not all the same, and they are paralleled :
The above three situations are in entire agreement with Kirchhoff s current law, as any parallel circuit must be.
The following are the requirements or conditions of paralleling D.C. generators :
Note. Whenever generators are in parallel their +ve and ve terminals are respectively connected to the + ve and ve sides of the bus-bars. These bus-bars are heavy thick copper bars and they acts as + ve and ve terminals for the whole power station.
