Abstract: To further improve the performance of de-icing equipment, this paper develops a system that combines functions of DC de-icing with dynamic reactive power compensation based on STATCOM. The system utilizes the topological structure of a double chained mode STATCOM, the dynamic reactive current tracking technique, and the neutral point skewing technique, to create the functions of reactive power support and DC de-icing. This paper first introduces the system structure, which is followed by a detailed discussion on the system control strategy. The output power characteristic of the system is then analyzed under different operational conditions to evaluate the system functional performance. In addition, an EMITDC/PSCAD based simulation model is developed to test the control strategy. Finally, a prototype machine with 12 MW rating of the de-icing capacity combined with a STATCOM is developed and used to conduct experiments to verify the feasibility of the system design proposed in this paper.

Key words: DC de-icing, reactive power compensation, STATCOM, neutral point skewing
