A voltage profile study was performed for the power distribution system of the Salem Nuclear Generating Station to determine the cause of an apparent misoperation of undervoltage relays. A dynamic model of the distribution system was developed for simulation of the bus transfer and from the generator's auxiliary transformer to the station power transformer. The work in validating the computer dynamic simulation model by a test is presented. It is shown that the PTI Salem Electric Model and PSS/E software package are able to predict the static voltages at the 460 V and 230 V buses within a difference of 1.6% of the measured values. In addition, the model-predicted transient condition comparison test and computer simulation results validate the ability of the model to predict static and transient voltage levels. An inquiry throughout the nuclear power industry indicated that the described validation program represents the most detailed and accurate method of validating the accuracy of the electrical power analysis software
