TACS enhancements for the Electromagnetic Transient Program [PDF]
Conference Proceedings Power Industry Computer Application Conference, 1993 Transient analysis of control systems (TACS) of the electromagnetic transient program (EMTP) has been enhanced in many ways. There are major changes in methods of ordering components to minimize the introduction of time step and history term errors. Initialization algorithms have been greatly enhanced to allow multiple frequency initialization.
