Breaker logic "PARALLEL"
Parallel operation is enabled by configuring parameter ╚═▷ 3411 to "PARALLEL".
Parallel breaker logic must be selected for the following operation modes:
• islanded operation •
• Mains parallel operation
•
In the event of an engine start request the following occurs:
• The GCB is synchronized and closed •
• The generator assumes load and the adjusted real power or reactive power setpoints •
are controlled
Following the stop request the following occurs:
• The generator sheds load until real power has reached the "Unload limit" •
(parameter ╚═▷ 3125 )
• The generator power factor is controlled to "1.00" (unity) •
• The GCB is opened •
• The engine is shut down following the configured cool down period •
When a stop command is issued to the engine, soft loading (power reduction) is carried
out before opening the GCB, except an alarm of class D or F is present.
Breaker logic "INTERCHANGE"
