This paper presents the modeling and simulation studies for the startup of a 250 MVA pumped storage unit in pumping mode and the startup of a 65 MVA hydraulic unit as a corrective action following an uncontrolled islanding of an area due to an extreme contingency. The new synchronous machine (SM) module of EMTP-RV enables the simulation of the machine from standstill and makes it possible to use it for studies including: analysis of the disturbances generated by the operation of the static frequency convertor (SFC) during electrical startup of a pumped storage unit and simulation of system restoration following a complete collapse of a major part of an interconnection. The proposed model is validated by using field measurements from a 250 MVA pumped storage unit for the period from standstill to line operation including the synchronization of the machine to the grid. ©2009 IEEE.
