The injection of unique high frequency voltage signals into a non-torque producing third sequence circuit of the machine provides current information for the estimation of the rotor angle and speed without generating any high frequency torque ripple. The fundamental voltage component impressed on the motor by the converter, with the estimated rotor angle and rotor speed are used for the speed control of the motor drive under minimum stator copper loss operation. In order to computer simulate the complete controlled drive, including both the fundamental and high frequency components a full order model of the motor is utilized. The control and estimation strategies proposed have been implemented on a 2 hp, 36 slots, 4-pole concentrated stator wound interior permanent magnet motor drive. Some simulation based on a full order coupled machine model and experimental results validate the proposed vector control scheme for operation at both low and high speed operations.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"1 1","pages":"853-859"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89881659","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, monitoring of the journal bearing condition in the field mainly relies on analysis of proximity probe or accelerometer signals. However, not all motors with journal bearings are equipped with such mechanical sensors due to cost or environmental restrictions. In this paper, the feasibility of applying motor current signature analysis (MCSA) for remote monitoring of mechanical instabilities in journal bearings produced by oil whirl and bearing clearance problems, is evaluated. In addition, a small-scale journal bearing test setup that can be implemented in low voltage motors for testing journal bearing faults under controlled conditions, is presented. An experimental study on a sealless fuel pump motor operating in the field, and on the custom-built journal bearing motor test setup shows that MCSA is capable of providing remote monitoring of journal bearing oil whirl and increased clearance for potentially preventing motor failure. The results of vibration analysis are also presented for comparative evaluation.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"1 1","pages":"300-307"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78583748","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}

A lot of effort has been dedicated to investigating the power stage control of VSG, but the waveform quality of VSG is not fully discussed. This paper analyses a VSG with an inner voltage loop to attenuate waveform distortion influenced by dead-time effect. And main parts of the voltage loop are voltage regulator and active damping of the LCL filter. Generally speaking, the voltage regulator attenuates the influence of dead-time effect, and the active damping suppresses the resonance peak caused by the LCL filter and makes it easier to stabilize the whole system. Based on the proportional-resonant (PR) compensator together with capacitor-current-feedback active damping which is widely used for their effectiveness and simple implementations, a step-by-step design method of the controller parameters for voltage loop is proposed. By carefully dealing with the interaction between the voltage regulator and active damping, the satisfactory regions of the controller parameters for meeting the system specifications are obtained, from which the controller parameters can be easily picked out. Simulation results verify the effectiveness of inner voltage loop.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"9 1","pages":"3760-3765"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75163495","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}

Li","doi":"10.1109/ECCE.2015.7310252","DOIUrl":"https://doi.org/10.1109/ECCE.2015.7310252","url":null,"abstract":"To satisfy the requirement of operating DG units in both grid-tied and islanding microgrids, relatively large shunt capacitors are often selected for the output LCL filters of power converters. This modification can bring a few challenges, such as harmonic distortions and steady-state tracking errors, to the line current regulation during power converter grid-tied operation. In addition, the line current control problems can be more severe when the model-based one-step deadbeat current control scheme is used to reduce the computational load of DG unit controller and to enhance the dynamic current response. To overcome these limitations, a resonance dampened control method is developed utilizing the concept of the recently proposed weighted average current control with two current measurements. First, the weighted average current is accurately controlled via a modified deadbeat control scheme based on a virtual filter plant. To reduce the line current tracking errors caused by weighted average current approximation, a simple feed-forward term using existing grid voltage measurement is added to the line current reference of the proposed deadbeat control. Simulated and experimental results validate the effectiveness of the proposed method.","PeriodicalId":6654,"journal":{"name":"2015 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"18 1","pages":"4194-4201"},"PeriodicalIF":0.0,"publicationDate":"2015-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75336794","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}
