What is typically required for a generator to operate effectively under an isochronous governor?

To operate effectively under an isochronous governor, strong baseline frequency control is essential. An isochronous governor is designed to maintain a constant speed and consequently a constant frequency in the generator output, regardless of changes in load. This control mechanism is crucial because the generator's speed—and hence frequency—must remain stable to ensure reliable power delivery and system integrity.

In an interconnected power system, maintaining frequency is vital for the synchronization of various elements within the grid. The isochronous governor adjusts the output to match the load automatically to keep the frequency consistent, which is significantly beneficial during varying load demands. Without strong baseline frequency control, the generator may struggle to respond adequately to fluctuations, leading to potential instability in the power system.

Other factors like frequent maintenance checks, accurate load forecasting, and high reserve capacity planning are important for overall operational efficiency and reliability, but they do not directly influence the isochronous governor's primary role of maintaining frequency stability. These aspects support the reliability of the generator's performance but do not define the essential requirement for effective operation under the given governor type.
