BEGIN NEW DATA CASE
C BENCHMARK DC-34
C Test of U.M. operating as a 3-phase synchronous machine. Data is in
C per unit. Although there is a phasor solution, manual initial conditions
C in fact define all state variables, so the answers would be identical if
C the negative (-1.0) starting times of the sources (T-start of cols. 61-70)
C were erased (made blank --- or zero). For automatic initialization of
C the same problem, see the second subcase (not normally executed). For a
C case of automatic initialization using data in physical units, see DCNEW-2

BEGIN NEW DATA CASE
BLANK { Note this extra blank will terminate execution, to avoid 2nd subcase
C 2nd of 2 data subcases is a modification of the first that illustrates
C correction of a U.M. bug by Yin Yuexin as explained in his September,
C 1990, article in EMTP News. Automatic initialization of this data case
C gave the wrong answers (although it did run) prior to correction of the
C UTPF around 23 October 1990. Now, answers are close (most variables
C differ by about 1% on the final time step). Printout of the final phasor
C solution has deliberately been omitted, so those wanting to verify this
C computation can observe only the total network loss (see comments below).
