A large portion of these nonlinear loads inject harmonic currents into the distribution system, which in consequence produce harmonic voltage distortion. This paper proposes a power electronics based system that besides the reduction of voltage harmonic distortion converts harmonic energy that would normally be wasted in additional losses in feeders, transformers and motors (harmonic energy wastage) into useful energy. It is possible to denominate this system a harmonic energy recycler. The proposed system is a shunt active power filter (SAPF) driven by the voltage detection control strategy (VSAPF) and implemented with a highly efficient voltage source converter (VSC). This paper makes a theoretical power analysis of the VSAPF and covers the design of a highly efficient system that makes the harmonic recycler device feasible. Furthermore the functionality of the proposed system is validated by simulation.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123186896","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}

This is due to their high reliability and fault-tolerance capabilities. A substantial amount of research and development is carried out to design and test these machines. One of the necessary tests is the full-load test, where the machine's thermal design is verified. Normally, this test requires another machine, with the same power rating or higher, to be mechanically coupled to the tested machine, while the converters are connected in the back-to-back configuration. This paper introduces a novel technique of implementing the regenerative test for six-phase induction machines with symmetrical or asymmetrical winding configuration. The proposed approach is capable of validating the thermal design of the machine without the need for coupling another machine as a load. The scheme utilises indirect rotor-field oriented control (IRFOC) to achieve the full-load test. The rated active power is flowing in closed loop from one winding set to another. The only power used during the test is to cover the losses in the machine and the converter. The proposed control scheme is novel since it utilises the y-component from the vector space decomposition (VSD) subspace, instead of implementing the multiple vector control (multi-stator, MS) approach for each winding sets. The proposed scheme is validated through the simulation results.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123257358","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}

Signals generated there enter into the controller and act as feedforward signals that are evaluated inside of a cost function with other predictions. Measured position is used as a feedback and the speed and load torque are estimated by Kalman filter. The control is formulated in the dq coordinate frame. Simulation results show that the performance of the proposed position controller is significantly improved by using the proposed feedforward terms in the cost function when comparing to the cost function without these terms.

The parallel connection offers better emulation precision due to the increased number of available voltage levels and the higher apparent switching frequency. The concept to emulate the transient inductance and the inner voltage of an AC machine is introduced and analyzed in a single phase model using interleaved modulation in the parallel arms, and level shifted carriers for the upper and lower side of the arms. The static and dynamic precision of the emulation is influenced by the current balancing applied for distributing the power evenly on the parallel arms. A compromise is required to keep both the emulation and balancing error at low level.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703636","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}

Therefore, this study proposes a realistic analytical model to investigate the behavior of the stand-alone DFIG, through simulations. The study examines the validity of several existing analytical models of DFIG and focuses on one in particular, which is derived from the stator and rotor voltage equations in the separate (natural) reference frame. This model is built using Matlab/Simulink conventional building blocks and simulated to explore the behaviors of a stand-alone DFIG in transient and steady-state, under no-load and linear/non-linear load conditions. To verify the accuracy of the proposed model, it is compared with two different pre-built DFIG models in Simulink and in Plecs. The comparative simulations, carried out simultaneously under the same conditions, verify the validity of the proposed analytical model. As the advantages, the proposed model is easy to build, runs faster compared to pre-built Simulink model and is also convenient for analyses of stand-alone DFIGs for real operational conditions.","PeriodicalId":251046,"journal":{"name":"2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127370474","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}
