Parallel Operation Of Compound Generators

The parallel operation of compound machines is similar to shunt generators. Differential compounding would produce a drooping external characteristics and satisfactory parallel operation is made easy. But most of the generators are used in the cumulatively compounded mode. In such cases the external characteristics will be nearly at making the parallel operation more difficult. By employing equalizer connection for the series windings this problem can be mitigated. Fig. 40 shows the connection diagram for parallel operation of two compound generators.
