A naval DC IPS will include multiple power generation devices, energy storage devices, and layered power converters. Power converters coupled to high-bandwidth regulators exhibit constant power load (CPL) behavior. CPLs exhibit negative non-linear impedance which reduce stability margins and limit the efficacy of linear control methods. Incorporating megawatt level pulsed loads, such as laser weapons or railguns, challenges the limits of linear control methods. A recently introduced control scheme, Adaptive Select-Matrix LQR (LQR-SM), is a flexible and adaptable centralized control approach to multi-input, multi-rate, high order systems. This paper presents a comparative study of LQR-SM controller performance in a naval medium-voltage DC shipboard electric distribution system with CPLs. The four configurations studied are a full-order adaptive LQR-SM controller, two adaptive reduced-order controllers, and a non-adaptive full order controller. The controllers are compared on the basis of quality of regulation, size of region of attraction (ROA), computation load, and stored-energy efficiency.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"67 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120811884","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}

This requires a higher medium voltage (MV)-rated power device, a semiconductor technology that enables compactness and light weight, and easily integrated into modular proven power conversion architectures. This envisioned system takes the generated 4.16–13.8 kV, 60 Hz, AC power and rectifies it to MVDC. The rectified MVDC is then isolated before being distributed throughout the ship where it is converted at diverse AC and DC loads. This can be accomplished using silicon carbide (SiC)-based power conversion topologies switching at >20 kHz, thereby eliminating heavy and bulky isolation transformers onboard and improving the IPS power density to that expected from next-generation warships. This paper presents a new approach for an IPS, based on a Common Power Electronics Building Block (CPEBB), using both 6.5 kV / 200 A SiC H-bridge in an optimized industry-standard XHP™ 3 package and a 10 kV / 240 A SiC dual in an optimized custom package. This architecture, with power dense MV converters/inverters, is enabled by the higher blocking voltage and higher switching frequency of the SiC technology. The proposed Multi-Secondary Solid-State Transformer (MSSST) is the fundamental building block which enables this high performance MVDC IPS.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"187 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123011680","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, the symmetrical components of the fault current are used in a new feeder protection method for the maritime applications. The new method is effective against the phase-phase fault and relies on evaluation of the ratio of negative-sequence to positive-sequence current to detect such faults. It is shown that the proposed ratio is a complex number and its magnitude is associated with the presence of the phase-phase fault in a radial feeder, while its argument is an indicator of the fault direction. Precisely these information are used in this paper to detect the phase-phase fault and to indicate the faulted section of the feeder. Using PSCAD, the new method is implemented in a test Medium Voltage feeder with variable generation and relatively reduced short-circuit currents, thus resembling the electric network on a ship. The simulation results demonstrate that the proposed method of protection provides an improved performance compared to the conventional OverCurrent relays in a radial feeder with variable short-circuit power.","PeriodicalId":227033,"journal":{"name":"2017 IEEE Electric Ship Technologies Symposium (ESTS)","volume":"257 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121583169","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}
