Inrush current requirements analysis for FAA facility power systems FAA设施电力系统的涌流需求分析

{"title":"Inrush current requirements analysis for FAA facility power systems","authors":"Y.C. Hubbel, C. Sweetra","doi":"10.1109/IAS.1993.299231","DOIUrl":"https://doi.org/10.1109/IAS.1993.299231","url":null,"abstract":"Martin Marietta Corporation was tasked to perform an analysis of developing a new inrush current requirement which will be cost-effective and technically acceptable for facility power system stability and which can be met by adequately designed electrical/electronic equipment. This analysis of an allowable inrush current is based on the characteristics of the facility branch circuit breakers which provide power to subsystems on the critical bus. A recommendation is made and an inrush current requirements curve is developed to replace the existing limits stated in FAA Order 6950.2c and FAA G 2100e. The curve identifies a range of inrush limits to be imposed by comparing the amount of inrush a system is allowed to produce versus the length of time a system should be required to return to within 110% of the normal steady-state condition. Requirements developed from the curve are based on individual system measurements (shorter duration requirements) as well as facility circuit breaker characteristics (longer duration requirements). Systems falling between these limits may not exceed the requirement identified at the curve. As a result, a significant FAA cost avoidance can be realized when special soft-start devices are not needed for all equipment, thus allowing greater use of commercial-off-the-shelf equipment.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407278","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 effectiveness of the device has been verified on weeds like Poa annua L., which has always been a problem on golf courses. The electrical resistance of weeds has been found to drop drastically as a result of electrical discharge through them. Ground potential distribution has been studied as a safety check. All the results obtained indicate that this device is very safe for the operator. The device is about to go into commercial production.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"153 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125900296","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 single-gap circuit is effective for generating moderate peak voltages, but is limited by a multiple sparking phenomenon. A double-gap circuit can achieve equal peak voltages with every spark, but with a reduced number of pulses, compared to the single gap. Both configurations have an upper voltage imposed by the changing impedance of the reactor as voltage and frequency are varied. The pulse characteristics are reported for both types of circuits, along with some spectroscopic analyses. The general performance of the reactors for destruction of some compounds with both circuits is also reported. The single-gap supply is shown to provide a wider range of operating parameters than the double-gap supply but it is much more difficult to characterize the pulses, particularly their frequency, than with the double-gap supply.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127062496","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 inverter is one of the components of an uninterruptible power supply system providing up to four hours standby for interlocking and track-side equipment. The small light-weight inverter incorporates an ultrasonic AC link, thus facilitating the use of a ferrite transformer for input-output isolation purposes and resulting in the practical implementation of the modularity principle, ZVS (zero voltage switching) is achieved by good circuit layout and controlled transformer capacitance. A novel integrated sensor in the transformer is used for flux balancing purposes and the associated airgap contributes to the ZVS process. Enhanced modulation depth is realized for inductive loads by allowing a large-frequency AC ripple on the DC bus.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"385 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130138415","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 system, an adaptive rotor flux observer of a full-order type is used not only to construct the direct field oriented controller but also to identify the stator and rotor resistances of the servo motor. The rotor flux observer is used to reduce the sensitivity of a deadbeat controller to parameter sensitivity. The fundamental characteristics of this system are discussed on the basis of experimental and simulation results. The induction servo motor drive system employing this method is used to improve the efficiency of an induction servo motor without sacrificing dynamic performance.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131093040","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 potential variation is analyzed with the focus on the current flowing out of or into the neutral point of the DC link. The theoretical minimum capacity of the DC link capacitors is discussed for its application to both a vector-controlled induction motor system of 2.2 kW and a SVC system of 10 MVA, 6.6 kV, 60 Hz. It is shown that the proposed control scheme makes it possible to suppress the neutral-point potential variation within a few percent, so that the total capacity of the DC link capacitors in the NPC-VSI is almost the same as that in the conventional voltage source inverter.<<ETX>>","PeriodicalId":345027,"journal":{"name":"Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121286202","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 number of RWPM strategies have been reported, and a beneficial impact on acoustic noise and vibration has been unamiously agreed upon.
