Power station generator load distribution circuit - measures peak load from individual true and ractive load values

摘要

The generator load distribution control is suitable for parallel diesel generators in a power station installation. Each generator set has a true and reactive load detector with diodes to indicate the actual and peak values. A comparator compares the load value with the peak values. A comparator compared the load value with the peak and the output signal passes to a speed comparator. A control signal is used to alter the drive motor speed (12) accordingly. The reactive load regulation is carried out by comparing the reactive load with the peak value (31), the resulting signal being used to drive a controller (32). The output is amplified (33) and used to adjust the excitation current in the exciter winding of the generator.
