Power Needs

The target of this paper is to evaluate influence of increased bus voltage of power converter on motor insulation system. This is required for the evaluation of motors for 800 V DC bus based servo-amplifiers. Increase of DC bus voltage is a logical consequence of higher power needs for servo-drive systems.

Generating System

Design method of main circuit parameter based on theoretical calculation and engineering practice is developed for permanent magnetic direct-drive wind power generating system with dual PWM converter topology. DC bus voltage, DC bus filter capacitor, rating value of power electronic devices and gird-side LCL filter parameters are calculated for an experimental wind power generating system. Hardware platform is built using calculated parameters, and the experimental results show that the design method is viable and expected design goal is achieved.
