The purposes of the proposed control strategy are to correct voltage imbalance of the DC link capacitors, to keep the input power factor at near unity, and to achieve adjustable-speed drive. The five-level rectifier is controlled by the instantaneous-value-compared current control method using multi-band hysteresis comparators. On the other hand, the five-level inverter is controlled by the space vector pulse-width modulation method. The validity of the control strategy is verified by experiments using a 3.7 kW induction motor.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

Simulation of shaft vibrations due to interaction between turbine-generator train and power electronic converters at the Visund oil platform Visund石油平台汽轮发电机组与电力电子变流器相互作用下的轴振动仿真

Initially, these problems were believed to have a pure mechanical nature. The generator shaft was therefore modified to increase its inherent damping, but this only partly solved the problem. The focus was eventually directed to possible sources for the problems within the electrical power grid, especially two 7 MW variable speed drives (VSD) that serve as compressor drives. These drives are designed as current source converters (CSC), which feed synchronous motors. In order to clarify whether the vibration problems were caused by interaction between the VSDs and the generator train it was decided to carry out a detailed analysis using the simulation tool PSCAD/EMTDC. The simulated system includes a fully detailed model of the two 7 MW compressor drives and the turbine-generator train, as well as other relevant parts of the electrical system. The simulation results show that the VSDs can cause excessive vibration levels by two different phenomena: interharmonics and negative damping. It is verified that the redesigned shaft gives a lower vibration level, and that the resulting vibration level becomes reduced in the presence of passive electrical loads. The results and the simulation model are subject to further analysis in order to find permanent corrective actions to the problems, e.g. by means of dedicated power electronic devices.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

In the proposed converter, the power factor and line current distortion are improved by using the third winding of the energy-storage reactor of buck-boost converter, and the high power efficiency is achieved by the soft-switching operations of the main power switch and output rectifier diode. As a result, it is clarified that the proposed circuit satisfies the IEC 61000-3-2 Class-D against changes of load. The maximum power factor is 0.83, minimum THD is 68% and maximum power efficiency is 92% at rated condition. Furthermore, it is revealed that the superior dynamic characteristics can be obtained under this circuit condition, and that the most suitable circuit parameters are obtained in both steady-state and dynamic characteristics.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

When the wheels of the train slip on the rails, the torque is decreased to avoid the continuous slipping. The reason is that the tractive coefficient between the wheels and the rails has a peak at a certain slip velocity. But this adhesive phenomenon is not clearly examined or analyzed. Thus we have developed a new adhesion test equipment. In this paper, we measured the tractive force with this equipment, and clarified the adhesive phenomenon. Then we proposed a new tractive force control and verified the effectiveness of the proposed control scheme.","PeriodicalId":320424,"journal":{"name":"Proceedings of the Power Conversion Conference-Osaka 2002 (Cat.

The main drawbacks of SRMs are large torque ripple and acoustic noise. The torque ripple can be reduced by the stator current waveform shaping.
