DC Voltage Measurement and Control for Cascaded STATCOM
摘要
Abstract
A practical method of measuring DC capacitor voltages for individual inverter units was proposed based on the principle of phase-shifted carrier modulation method. This method can reduce substantially the number of voltage transformers required in the conventional voltage measuring method, simplify the system structure, and enhance the system stability. Furthermore, this paper presented a control method of balancing the DC voltages. The simulation was performed on a Simulink model of ±50 Mvar static synchronous compensator (STATCOM) and a DSP-based ±1.5 kvar STATCOM prototype was built. The simulation and experimental results verify the correctness and the feasibility of the proposed DC voltage measurement and control method.关键词
