Static and dynamic load distribution refers to how power needs are allocated. Static distribution uses predetermined rules, while dynamic distribution adjusts based on real-time conditions. Static methods are predictable but can be inflexible, while dynamic methods are more adaptable, but can be more complex.
In essence, the choice between static and dynamic load distribution depends on the specific needs of the application or system. If the workload is predictable and consistent, static methods may suffice. However, if the workload is dynamic and unpredictable, dynamic methods are generally preferred for optimal performance and resource utilization.
A fundamental function of Power Management Systems (PMS) is automatic load sharing, which is typically achieved via the speed control of the diesel engines for active power, and via voltage control of AVR for reactive power.
Different power sources may share load in a symmetrical or asymmetrical way, SYMAP® devices provide both.
Load sharing can be performed by SYMAP® devices, which continuously send setpoint values to the speed controllers of the connected diesel generators, and to AVR for voltage control.
We support both main load sharing philosophies:
- droop control – engine speed decreases proportionally to load
- isochronous control – speed remains constant under varying load conditions
If the engine controllers do not support active power control, SYMAP® can assume this function through high-speed communication, enabling fully automatic load management across all paralleled generators.
