In underground earthing and protection environment, CMV is associated with potentially undetectable fault currents, due to their diversion away from the protection circuit. An ideal solution to these problems would be such a VSD that creates minimum or zero CMV and removes the alternative paths for the fault currents. Previous study performed by the authors has suggested that, amongst the existing drive topologies used by the industry, a 2-level Inverter with Active Front End (AFE) would be ideally suited for CMV elimination. This paper develops a control strategy for the VSD based on AFE Inverter such that it eliminates CMV, minimises EMI and optimizes harmonic distortion at the drive input and output sides. To validate the proposed strategy, a laboratory prototype VSD has been developed and the test environment has been set up to represent an underground mining electrical system. Experiments have confirmed that the prototype VSD generates practically no CMV, thus eliminating the EMI problem. Under an earth fault, the fault current flows into the designated protection circuit, thus providing the required electrical safety of the proposed VSD.","PeriodicalId":376719,"journal":{"name":"2019 IEEE Industry Applications Society Annual Meeting","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685658","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}

Another form of dynamic load model is the transfer function based load model. Although both types of dynamic load models are well accepted, there is no comparison done regarding their performance, and no evaluation on the influence of voltage and frequency dependency terms on the overall model accuracy for transfer function based load models. In this paper, a transfer function based load model is developed analytically using a composite load model. Dynamic responses of the developed transfer function based load model and the original composite load model are compared subjected to various voltage and frequency disturbances. The transfer function based load model is a function of both voltage and frequency, three levels of simplifications are made to the full model in order to evaluate the corresponding accuracy. It is found the reduced model with both the 1storder voltage $Delta mathrm{V}$ term and 1storder frequency Δf term has the smallest error among the three reduced models.","PeriodicalId":376719,"journal":{"name":"2019 IEEE Industry Applications Society Annual Meeting","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114181361","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 particle collection and pressure drop performance tests of the lab scale EME having single channel geometry with a collection area of 0.5 m2 were conducted at various gas velocities and applied voltages, and also compared to those with the Chevron type mist eliminator. The pilot scale EME designed from the lab scale with collection area (4.6 m2) was tested at a fixed velocity of 4 m/s with and without the Chevron type ME, and its long term performance was evaluated for approximate 400 minutes. Mists smaller than $mathbf{10} mu mathbf{m}$ including CaCO3 were generated and an optical particle counter and EPA test method 5 were used to measure particle collection efficiency and emission concentration. Experimental results showed that collection efficiency of the lab scale EME at 4 m/s was approximately 3 times higher than that with the Chevron type, while pressure drop was only 8% of it. Particle emission from the pilot scale EME with multiple channels was 2 mg/m3 and decreased to 1.4 mg/m3 when it combined with the Chevron. Even though the initial particle collection efficiency of the pilot scale EME, 71.2%, was decreased to 60.5%, the efficiency was recovered almost to the initial state after 10 min water cleaning with 43.5 L/min.","PeriodicalId":376719,"journal":{"name":"2019 IEEE Industry Applications Society Annual Meeting","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127006046","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}

Solid rotor cage induction motors (SRCIMs) are perfect nominees to such applications, owing to their high reliability. However, the restrictions over ferromagnetic materials and manufacturing process overwhelm the SRCIM design. The motor is required to have low power losses in stator core and the solid rotor. Furthermore, low number of rotor slots is demanded in order to facilitate welding process in rotor side. Those two objectives are contradicting in design stage. This study investigates the losses characteristics of high-speed SRCIM considering the behavior of different ferromagnetic materials, and the complexity of welding process of solid rotors. With a 160-kW and 3000-kW SRCIMs, the influences of stator ferromagnetic material, rotor conductivity, slot combination and air-gap length on power loss characteristics are comprehensively analyzed. Based on the aforementioned analysis, an optimal design criterion for SRCIM is proposed to decline the eddy current losses and decrease the complexity of welding process in the SRCIM's rotor. To verify this criterion, a 160-kW SRCIM prototype is designed and manufactured. Experimental validation is performed and the effectiveness of the proposed design procedure is verified.","PeriodicalId":376719,"journal":{"name":"2019 IEEE Industry Applications Society Annual Meeting","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125936359","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}
