Understanding Transient Reactances

Power generation systems consist of numerous components, each playing a specific role in providing reliable power to consumers. The manufacturer specifications for these systems are intended to clearly state the values and functions of components to ensure reliable operation for a given application. However, these specifications often omit key information or may state requirements in a confusing manner. One of the best examples of this is when looking at the transient performance of gensets in situations such as starting large motor loads. Clear communication of genset performance is the key to ensuring the customer receives what they need for their specific application, but the relevant information is often buried in confusing terminology.
