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).
