Analytical Modeling and Design of Capacitor Bank Considering Thermal Coupling Effect

The inevitable electrothermal coupling among capacitors in a bank will lead to nonnegligible errors the temperature as well lifetime prediction of individual capacitor. In this article, analytical thermal models with corresponding design for capacitor banks are proposed considering effect. First, measurement-based lump model and physical-model-based proposed. Then, help models, method matching is by optimizing parameters capacitors, such rated actual loading. To validate accuracy design, case studies based on nine presented.
