What is Paralleling ??
- Make two or more small gensets work together and act like one BIG genset.
- Power available is the sum of all the machines in the system.
Generator sets can be paralleled to other generator sets or the utility. To operate in parallel, both units must match phase sequence, voltage, frequency, manage neutral currents, operate with the same frequency directional rotation and produce almost exact sine waves. Only after these conditions are met can the units be connected together by a breaker.
Why Parallel Gensets ??
- More Reliability
- More Performance
- Cost Effectiveness
Don't Parallel when :
- Existing gensets not compatible with new.
- Loads can't be split and controlled.
- Gensets are very small (under 300kW)
