Req:Mesh Fault Current

= Application concept (zFault Method) =

The purpose of zFault method is to study the effects of various faults on a power system. These studies will be performed by adding zFault capabilities to power-flow module in GridLAB-D

Performing Fault analysis on a power system with multiple swing nodes is not expected to be part of the GridLAB-D functionality at this time.

= Use Case =

Initial plans are to use this capability to perform fault studies complex urban downtown feeders - as part of the smart-cities research.

= General Requirements =

zFaullt method shall perform fault analysis to find fault current and fault voltage at a particular node for unbalanced mesh distribution systems.

Below are the required capabilities:

R1
Method will solve for fault parameters when a fault is imposed on the system

R1.1
Method will support meshed topology

R1.2
Method will support unbalanced systems

R1.3
Method will provide fault current for supported types of faults

R1.4
Method will provide indications of voltage influence for supported types of faults

R2
Method shall be part of the power-flow module
