However, such motors are prone to generation of bearing current which causes bearing wear through electrical discharge machining (EDM). Present methods for diagnosing bearing current are based on vibration spectrum analysis, monitoring the waveform of the shaft voltage or monitoring the current flowing through the carbon brush placed between the shaft and the motor frame. These techniques, requires mandatory site inspection and special arrangement for data collection. As a result, these methods are not feasible in all industrial cases. Therefore, development of an alternate non contact and non intrusive technique is required to easily detect the presence of bearing current. This paper proposes a method to effectively detect the presence of bearing current using motor current signals only. These signals could be easily collected from the motor control panel itself. The proposed method does not require any site inspection or additional fittings, which makes it applicable for every industrial scenario.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123558230","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 probable key for enhancing the electric power system operations is BESS with a high point of wind penetration in the electric grid. In energy mix scenario, high penetrations of wind generation have intermittency and volatility issues. To handle these issues, an ISO performs SCUC to ensure system security and reliability. Integration of synergies BESS can balance and mitigate the intermittency issue of wind power generation. In this paper, SCUC model is simulated in GAMS software using mixed integer programming (MIP) with BESS. Results are compared for the BESS combined power system scheduling with and without energy storage is observed for dissimilar stage of wind power generation. In sequence to demonstrate that efficiency of the proposed model, it is implemented on a transmission system of eight buses.

The proposed topology can produce a 19-level output waveform with fewer count parts. It consists of two bridges with individual low-frequency transformers. The bridges can generate quasi-square waveform and pulse width modulated (PWM) waveform independently and energized the two transformers whose secondary terminals are cascaded to attain the maximum number of levels in the output voltage waveform. Presence of the transformer in the configuration mainly provides the inbuilt isolation between the supply and load, higher order harmonics are filtered out due to the leakage inductance of the transformers and ratings of the power electronic switches are reduced since the transformers are boosted up the voltages. As per switching concerns, this paper presents the most common LS-SPWM technique with a new carrier to improves the fundamental magnitude and shifts the dominant harmonics into three times of the traditional strategy for the same modulation indices. The detailed loss analysis of the converter is also presented. The performance of the proposed topology is validated with MATLAB-Simulink software.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128786286","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 this paper, a Non-Dominant Sorted Genetic Algorithm II (NSGA II) based multi-objective approach is developed for optimal deployment of DG to maximize voltage profile improvement, reliability, economic and environmental benefit. To address the issue of intermittence of renewable DG, Battery Storage System (BSS) is also used in the system. A new formula is proposed to evaluate the failure rate of the distribution line. Reliability indices such as Expected Energy not served (EENS) is used to assess the reliability of the network by the incorporation of DG. New and logical formulas such as Network voltage profile improvement index (NVPII), Benefit Cost Ratio (BCR), and Environmental Benefit Index (EBI) are formulated to assess the overall performance of the device The proposed method is tested on 33-bus radial system for time variant practical load models. The proposed technique when compared with other multi-objective algorithms shows good applicability and superior performance. This analysis facilitates the planning engineers to choose an optimal approach for the overall benefit of the system.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"169 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122801204","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}

Few works are also available in literature about vibration analysis of inter-turn fault motors. In vibration monitoring authors have majorly focused on the fundamental rotational and supply harmonics hardly up to four. It is not ideal to judge whether the rise in vibration amplitudes at these harmonics are due to electrical faults such as voltage unbalance, air gap eccentricity, bowed rotor, inter-turn faults or due to mechanical faults such as misalignment, looseness, weak base etc. So, there is a need for further studies in vibration analysis of motors under inter-turn fault. Experimental investigations have been performed to study the effect of inter-turn fault on rotor slot harmonic amplitudes. From the experiments, it is clear that inter-turn fault also results in increase of vibration amplitudes at rotor slot harmonics.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130360613","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}
