With more DG units being integrated into the power system, a more recent concept, called microgrid, is developed by grouping a cluster of loads and parallel DG units in a local area. This paper addresses the issue of real and reactive power control for DG units in a low voltage (LV) microgrid during the autonomous islanding operation. The traditional method for power control in parallel DG systems is the frequency and voltage magnitude droop method, which is based on the assumption of a mainly inductive line impedance, and is subject to power control couplings when implemented in a LV microgrid, where the line resistance to reactance ratio (R/X) is high. It is also revealed in this paper that the traditional droop control can lead to stability concerns in a LV microgrid. To achieve accurate and decoupled real and reactive power control and at the same time, to improve the system stability, a virtual frequency-voltage frame control is proposed, where the original voltage and frequency frame is transformed to a virtual frame to realize a completely decoupled relationship between real and reactive power. Details of frame transformation control and small signal stability analysis are presented. Both simulation and experimental results are provided in this paper.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115331840","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}

In the process of connected DG with the power grid, harmonic/inter-harmonic is very serious problem. A new method based on modified MM filter and HHT is proposed to detect harmonic/inter-harmonic caused by the power electric elements. Researched intensively the characteristics of MM transform and MM filter, MM filter is modified aimed at the drawback of selection of structure elements and statistic deflection. HHT is perfectly self-adaptive analysis method. To the signal with harmonic/inter-harmonic, white pulse and positive & negative impulse, firstly, using modified MM filter to remove the white noise, positive & negative impulse and high times harmonic because of its low-passing characteristic, that method's key element is to choosing appropriate SE and its filter effect is better than the wavelet transform. Based on this, using EMD to get a set of IMFs for the denoised signal, the IMFs are almost the single frequency signal. At last, carrying out Hilbert transform to IMFs can get the instantaneous frequency and amplitude of every harmonic/inter-harmonic accurately.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116018754","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}

The principle of producing magnetic suspension forces for the AC-DC-3DOF-AMB is introduced. The flux path of the AC-DC-3DOF-AMB is calculated by using equivalent magnetic circuit method, the mathematics models of magnetic suspension forces are deduced, and the experimental prototype of this novel bearing is designed. The flux path and magnetic suspension forces of the rotor are verified by finite element analysis software ANSOFT. The nonlinearity of magnetic suspension forces and the coupling characteristics of movement and electromagnetic couplings around the balanceable position are calculated and analyzed by MATLAB software. The theoretical research and simulation results have shown that the mechanical structure and flux path of this AC-DC-3DOF-AMB are reasonable, and the maximum suspension magnetic forces satisfies design requirement. The magnetic suspension forces have better linearity and symmetry around the balanceable position. There are almost no movement and electromagnetic couplings among 3 degrees freedom of this magnetic bearing.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123010513","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}
