The shunt capacitors compensate the fundamental reactive power, the shunt APF eliminates the harmonics and the small amounts of load reactive power. But when they work in the same electric utility there exists resonance problem, in order to avoid resonance, the compensation character of hybrid compensation device under traditional strategies for current type nonlinear load were well studied theoretically and quantitatively by establishing mathematic model. A new current control strategy, which not only suppress line-side harmonic current and reactive power but also avoid resonance between shunt capacitors and line-side impedance, was put forwards. And a new compensator method which the APF only compensates 1/2 reactive power of each shunt capacitor was provided, due to the APF could compensate both inductive and capacitive reactive power. It lower the capacity of APF, and reduce the cost. Simulation show that the new control strategy and the new compensation method work stable, fleetly and effectively eliminates most harmonics and compensates majority reactive power.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133411807","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}

Zha","doi":"10.1109/IFEEC.2015.7361508","DOIUrl":"https://doi.org/10.1109/IFEEC.2015.7361508","url":null,"abstract":"An improved RCD snubber for solid-state circuit breaker (SSCB) is proposed in this paper in a low-voltage DC microgrid to protect SSCB against overvoltage caused by its tripping at the occurance of a DC-bus fault. Instead of relying mostly on the snubber capacitor to absorb the fault energy like commonly-used RCD snubbers, the proposed RCD snubber uses the snubber diode and an additional snubber resistor to form a separate path, which allows most of the energy to exhaust itself away from the snubber capacitor. In this way, the overvoltage across SSCB can be suppressed without increasing value and capacity of snubber capacitor, while the fault energy can also be quickly spent. Snubber process is discussed detailedly at a line-to-line fault to prove its effectiveness. Also, a design method is presented because former studies on parameter design of RCD snubber usually aim for converter appliance and cannot be directly applied on the proposed RCD snubber, which must be able to operate under fault current and thereby lays more stress in the peak value damping of overvoltage instead of quick suppression. Finally, simulations are conducted to prove its effectiveness in overvoltage suppression and fault current absorption.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124546077","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}
