Synchronous Machine Modelling Using Simscape

Cummins Generator Technologies (CGT, established 1904) designs, manufactures, and validates alternators under the renowned brands of STAMFORD and AvK. Based in Stamford, Lincolnshire, UK, CGT has branch manufacturing plants in Romania, India, and China. With a nominal 7.5 to 11,200kVA range, CGT alternators are suitable for a variety of applications.

In the modern business environment, to achieve product reliability and commercial growth, a company must be able to accurately simulate and analyze machine performance across multiple varied, realistic conditions in a low-cost and time-efficient manner. MathWorks products offer an integrated simulation environment for Model-Based Design. Simscape™, Simulink^®, and MATLAB^® provide the blocks, tools, and algorithms for efficiently designing and testing physical and control systems.

In this talk, Peenki describes how using Simscape products to develop multidomain synchronous machine models allowed CGT engineers to shorten the alternator design cycle. The models, calibrated using validated field data, allowed CGT to accurately and efficiently predict the transient response for the synchronous machines over a range of alternator fault conditions.
