To this end, international standards define precise methods to test if the dimensions are within the established tolerances, indicating whether they meet the required specification. The standards describe these methods using gauges that technicians can use to manually verify the dimensions of the product. In some cases, these methods provide different results from automated procedures, as they are based on different principles. To eliminate these discrepancies, this work proposes a novel automated method that emulates manual testing using virtual gauges. The proposed approach is based on an iterative procedure that aligns virtual gauges with the measured product shape, preventing one shape from penetrating another. This is achieved by assigning different weights to point correspondences according to their position. The result perfectly emulates the manual procedure, substituting the long and tedious manual procedure with a fast and robust automated alternative. Moreover, the proposed method can be applied to any dimensions with any type of gauge. Extensive tests with synthetic and manufactured rails corroborate the success of this approach.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134369404","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 event of failure of a breaker, adjacent breakers need to be called in to isolate the fault. Typically, a breaker-failure protection (BFP) function is integrated within commercial relays to monitor such situations. However, these functions are prone to mal-operation because of subsidence in current transformers (CTs) resulting from faults with significant decaying DC component. To this end, a reliable reset algorithm for the BFP function is presented in this paper. After measuring the decaying DC component within a one-cycle moving window, the proposed algorithm accurately distinguishes between the alternating pattern of fault current and exponential decaying pattern in subsidence current. Its performance remains unaffected during change in fault current level, decaying dc component, CT saturation and level of subsidence. Results from simulation as well as laboratory setup indicate that the proposed algorithm is able to prevent the mal-operation of an existing BFP scheme in the conventional relay with safety margin in the range of 20-40%. A comparative evaluation with available techniques testifies its superiority.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133353798","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}

Less attention has been paid to the use of WPT for electrical power distribution. An isolated WPT link with a high voltage-transfer-ratio can enable distribution of medium voltage directly to the application voltage at the point of use. The WPT link safely isolates the medium voltage input and steps it down to application voltages without exposing the equipment and end users to the dangers of medium voltages eliminating hazardous arc-flash energy. This concept provides safe medium voltage distribution inside data centers, replacing low voltage distribution with its large bus bars and cables bringing voltages larger than 1kV directly to the rack. The benefits of this power distribution scheme are summarized. A high efficiency proof of concept is developed to convert 1kV DC input to 48V DC output while transferring up to 10kW. The WPT transformer is developed with a planar magnetics structure. A U-shape ferrite configuration is proposed to improve mutual coupling by providing a low magnetic reluctance coupling path for the magnetic flux. The power transfer efficiency and loss distribution are analyzed.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125607037","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 capability to island from the grid during disturbances and continue supplying the loads locally helps improve the reliability and resilience of the network. This concept can also be extended to water micronets that, upon need, can disconnect from the main water distribution network and utilize locally available water resources. The scheme can be implemented both for rural communities where the centralized municipal water distribution network is not available due to geographical or cost limitations, as well as for small-scale communities whose water network is temporarily out-of-service as a result of natural or manmade disasters such as earthquakes, water contamination, flooding, etc. This paper proposes a framework and a solution for co-optimization of energy and water networks for a neighborhood of residential units, with the goal of maximizing sustainability, i.e. utilizing local energy and water resources as much as possible. It is assumed that distributed energy resources along with demand response are employed to meet energy demands, while a wastewater treatment plant (WWTP) built in the community is used to treat and recycle wastewater. The objective of this paper is to demonstrate mathematically how a self-contained community can schedule available energy and water resources optimally so that both energy and water demands are met with minimal external support. The problem is modeled as a multi-objective mixed-integer optimization model. A case study is presented as proof of concept.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124426821","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}

They can be aggregated and controlled autonomously, i.e. without the need for communication. A Space Heating (SH) load is a typical TCL with a heat storing capability that is a great demand response (DR) resource —a fast response option at low cost. In this paper, an autonomous DR control scheme is proposed to alleviate voltage violations of the local distribution system by managing SH loads. The proposed scheme attempts to set the SH operating point intelligently based on local measurements only. The proposed scheme bases its decisions on the voltage at the premise and the premise's voltage-to-power sensitivity (measured locally). By deploying machine learning, the proposed control scheme ensures that multiple SH loads, located at different nodes on the distribution system, contribute in a fair manner to mitigate voltage violations in the system without the need for communication. This controller also ensures an acceptable comfort level for the end-users. Simulation results verify the efficacy of the proposed control scheme in revamping voltage profile while maintaining fairness among and comfort of end-users.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127679398","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 concept of allowable power exchange interval (APEI) is introduced in the coordination of the integrated networks so that the transmission network can receive reserve capacity support from connected ADNs, which further exploits the flexibility in ADNs. Meanwhile, the risk of accommodating wind power has also been considered in the optimization to make a trade-off between the operational risk and costs and a tradeoff between the transmission network and ADNs. Besides, the alternating direction method of multipliers (ADMM) is adopted to decompose the centralized robust coordinated dispatch model for the integrated transmission network and ADNs into several dispatch sub-models. To efficiently release the computational burden, a new affine policy is adopted to transform the resulting nonlinear sub-models into linear optimization sub-problems that can be optimized effectively and globally with off-the-shelf solvers. The effectiveness and efficiency of the proposed robust decentralized approach was validated using two test systems.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"207 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121185731","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}

Nevertheless, when subjected to variations in its supply voltage, such device produces considerable luminosity changes, as shown in this present case-study, in which periodic variations of approximately 5% in the voltage, resulting from the driving of a flying shear of a hot rolling mill, cause variations of illuminance in the workplane superior to 10%. The hassle from such event, reported by workers, motivated the realization of this study, in which two solutions were proposed to solve the problem, which are the use of (i) electronic ballasts and (ii) LED lamps, being the latter chosen to be employed in a field test due to its technical-economic superiority. For the development of the work reported in this paper, it was initially made a detailed characterization of the functioning of the equipment responsible for causing the undesired voltage variations, as well as of the current lighting system. Local measurements were made for the illuminance and voltage profile, along with laboratory tests to characterize the HPS lamps performance. Taking into account acquisition, installation, operation and maintenance costs, along with lighting requirements, a comprehensive technical-economic analysis was performed to find the best solution for the real problem addressed in this paper.","PeriodicalId":115239,"journal":{"name":"2020 IEEE Industry Applications Society Annual Meeting","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128938343","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}
