+C BENCHMARK DC-38
+C ZnO simulation similar to DC-37, only here a 3-phase network is used.
+C The same arrester having characteristic i = 2500 * ( v / V-ref ) ** 26
+C is used, only here the coefficient has been cut in four (to COEF =625)
+C so that the column multiplier COL = 4.0 can be used: 4 * 625 = 2500.
+C Also, the usual, recommended (and more accurate) exponential modeling
+C (Type-92 nonlinear R(i) requested by "5555.") is only used for two of
+C the three phases. In order to illustrate the piecewise-linear alter-
+C native (requested by "4444."), such less-accurate modeling (for the
+C highly-nonlinear ZnO, anyway) has been placed in the 3rd phase ("c").
+C There are a total of 11 subcases.

+BEGIN NEW DATA CASE
+C 4th of 11 subcases is unrelated to the preceding, although it does use
+C a Type-91 TACS-defined R(t) as the preceding subcase does. But the
+C subject is quite different as should be explained in the April, 2003,
+C newsletter: corona modeling by TACS control of series R-L-C branches.
+C 27 December 2002, combine 3 separate, disconnected demonstrations of
+C TACS CONTROL of series R-L-C branches. The 3 disconnected subnetworks are:
+C 1) Series R-L with L fixed; R is ramped to a limiting value;
+C 2) Series R-L with R fixed; L is ramped to a limiting value;
+C 3) Series R-C with R fixed; C is is stepped (cut in half);
+C In each case, unit current at radian frequency 1.0 will be forced through
+C the branch, and voltage will be measured. There are 3 disconnected
+C networks, and there will be 3 screen plots to demonstrate reasonableness
+C of the answers.

+C First comes the R-L test where R is varied and L is held fixed. We have
+C 3 signals of interest: a) old Type-91 model; b) new TACS CONTROL;
+C and c) limiting value (for large times, this agrees with a and b):
+ TYP91 COMP 1000. { Inductance of 1 Henry is fixed half
+91COMP TACS OHMS { TACS-defined R(t) is the variable half
+ COMP 1.E+7 { Leakage path avoids floating subnetwork
+ RAMPR 0.5 1000. { New modeling begins with R-L branch
+ TACS CONTROL OHMS { TACS signal "OHMS" will define R of series R-L
+C A TOLERANCE= tag could be added to any TACS CONTROL card such as
+C the preceding if the tolerance EPSRLC for the application of parameter
+C changes should be different from EPSILN of the miscellaneous data card.
+C Location is arbitrary, so typically will be to the right of column 44
+C (end of the 3rd of 3 TACS names). For example, TOLERANCE=1.E-5 will
+C serve to define EPSRLC = 1.E-5 In that case, any relative parameter
+C change in excess of this value will order re-triangularization whereas
+C any smaller change will not. For this data, there would be no change,
+C however, since all changes are large. dT is artificially large.
+C The phasor solution of the Type-91 branch is wrong because Type-91 content
+C is ignored prior the the dT loop. Using SSONLY of STARTUP, we can add
+C a branch that will correct this problem. The following branch will be
+C present only during the phasor solution; it will draw the current that
+C really should be going through the Type-91 branch. This will avoid a very
+C high voltage spike (e.g., 1.E7) at time zero. It also demonstrates that
+C use of SSONLY is compatible with TACS CONTROL of a series R-L-C:
+ COMP NAME PHASOR 0.5 { Branch that will be erased as dT loop begins
+ LIMIT 6.5 1000.
+C Next comes R-L test where L is varied and R is held fixed. We have 2
+C signals of interest: a) assumptote (for large T): b) new TACS CONTROL:
+ ASSYM 0.5 2000. { Assymptote (where variation will end)
+ RAMPL 0.5 500. { Branch to be varied begins at 1/2 Henry
+ TACS CONTROL HENRY { TACS signal will define L of series R-L
+C Finally (3rd of 3), we have an R-C test where R fixed and C is is stepped
+C to correspond exactly to electric network switching (breaker opening). The
+C answer seems believable; it agrees by eyeball with switching.

+BEGIN NEW DATA CASE
+C 5th of 11 subcases illustrates a practical (although oversimplied)
+C application of the preceding. Data comes from Orlando Hevia of UTN
+C in Santa Fe, Argentina, as originally named TACSCAPA.DAT Data is
+C being added to this test case on 30 December 2002. Whereas the first
+C such example from Mr. Hevia involved 200 cascaded line sections, this
+C more manageable illustration involves just 2. TACS is used to vary the
+C shunt capacitance of the line as an approximation to corona. Note that
+C comment cards below are machine-produced (Mr. Hevia seems to have a
+C separate program to create such cascaded data automatically). Numerical
+C burden of the simulation has been reduced by a factor of 20 without much
+C loss to the plot or extrema. A factor of 2 was gained by shortening
+C the simulation from 20 to 10 usec, and a factor of 10 was gained by
+C increasing the time step from the original 5 nanoseconds (5.E-9 sec).
+C The surge (lightning) is fast, so very high frequencies are involved.
+C Note Mr. Hevia's use of JMARTI frequency-dependent line modeling.
+C Warning. 7 September 2003, the answer changes substantially following
+C the correction of an error in OVER12 (introduce new variable N7).

+C Using 1.E-3, this is reduced slightly to 148. This is the effect of not

+C of the 159 changes. Using 1.E-2, the "No. times" drops to 29; and using

+C arresters separately. With this branch present, the 6 N.L. elements all
+C are in the same subnetwork, so 6 N.L. equations in 6 unknowns are solved
+C by Newton's method at each time step. Without the branch, there will be

+C Without: Size 21-30: 9 0 12 3 -9999 9 -9999 ...
