Induction machine test case for the 34-bus test feeder -description

This panel is the second in a series sponsored by the Distribution System Analysis Subcommittee of the Power System Analysis Computing and Economics Committee to establish reference cases for induction machine modeling for distribution system analysis of unbalanced three-phase systems. A simple 4-bus test case has previously been addressed. This test case is more strenuous and is based on the 34-bus test feeder case published by the committee. It represents the placement of two large wind generators on a relatively weak rural distribution feeder. The data for parameters added to the test case are described. The test case consists of a power flow case and a single line-to-ground fault case. Results and modeling difficulties are discussed.
