A new medium voltage drive has been developed based on the active neutral-point clamped 5-level (ANPC-5L) topology with the option of transformerless network connection. In the last decade three-level neutral-point clamped (NPC) converters have become the industry standard in MV Drives. Although the three-level NPC converter has proven itself in the toughest applications in industry, the call for...
A new medium voltage drive has been developed based on the active neutral-point clamped 5-level (ANPC-5L) topology. In the last decade three-level neutral-point clamped (NPC) converters have become the industry standard in MV Drives. This configuration has proved very successful for applications where high power and high performance requirements necessitated the use of inverter grade motors and the...
This paper describes a method to include rotor based harmonics into a fundamental dq simulation model of a redundant dual-star synchronous machine. The model has been derived to add a minimum of additional equations and to allow identification of the required parameters from existing standard machine tests.
