Switching table and hysteresis controller in traditional DTC is replaced by flux linkage estimator and SVPWM modulation module. For the problems of complex control and harmonic interference when elevator's regenerative braking energy feed back to the grid, a method of storing renewable energy by super capacitor is proposed in this paper. Because the power changes in a large range in the process of charging and discharging, the super capacitor is accessed to the DC bus by a bi-directional DC/DC converter. The converter can achieve the function of limiting the inductor current and maintaining the DC bus voltage constant. A small signal model is established in the paper. The control strategy of double-loop control, outer voltage loop and inner current loop, can effectively control the super capacitor's charging and discharging process. Simulation results show that the method can not only solve the problems when energy feedback to the grid, realize the purpose of elevator drive's energy saving, but also effectively reduce the fluctuation of flux linkage and torque, and improve the control performance of motor.","PeriodicalId":288978,"journal":{"name":"2011 4th International Conference on Power Electronics Systems and Applications","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132217537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are disadvantages of the traditional SPWM current tracking control algorithm because the output current of the inverter is interfered by the network voltage. The improved SPWM current tracking control algorithm adds the feed forward loop of the network voltage to the original closed loop control system, which could effectively suppress the interference of the network voltage and guarantee the quality of the grid-connected current. In this paper, the advantages and disadvantages of several kinds of grid-connected current tracking control algorithms are compared. And the mathematical model of the closed loop control system is built. Then the paper analyzes the network voltage feed forward control algorithm. Simulation experiments are done based on the improved algorithm.
