Figure 4 - Microgrid Operation - Single Wire Method
Field Wiring:
The “power supply and digital control signals will go from “Islanding Assist Box ” to one Stabiliti and then
connection to subsequent Stabiliti will be daisy chained from this Stabiliti. CCS must control both the
“Islanding Assist Box” and the GIC to achieve the same operation as performed by CE+T supplied Islanding
Switchgear (as described in the previous section). It is customer’s responsibility to design appropriate
wiring and control algorithm to achieve the same. The figure above serves as a guide to achieve required
field wiring.
Note : Regarding the “Islanding Assist Box”, CE+T can provide design documentation but will not be able
to have one built for the customer. It will be customer’s responsibility to build one as per provided
documentation. It is also customer responsibility to design the CCS to control the “Islanding Assist Box”.
