IEEE (1992/2005) DC1A Model<br /></p><p><br /></p><p>This model is used to represent field-controlled dc<br /></p><p>commutator exciters with continuously acting voltage regulators (especially the direct-acting rheostatic,<br /></p><p>rotating amplifier, and magnetic amplifier types). Because this model has been widely implemented by the<br /></p><p>industry, it is sometimes used to represent other types of systems when detailed data for them are not<br /></p><p>available or when a simplified model is required.<br /></p>
