This document outlines the operational limits of a generator, including: 1. The maximum continuous rating limits the generator's stator current, voltage, rotor current, voltage, MW output, and power factor. 2. There are five principal limitations on operation: stator current, rotor current, MW output, stability, and stator end heating. These limitations can be represented on a "capability curve" diagram. 3. The document then describes each limitation in more detail, explaining how exceeding design limits could damage the generator. It provides examples of allowable overloads and hydrogen pressures before damage may occur.
