Modern marine vessels look to employ integrated full electric propulsion systems. This, together with the proposed increase in use of power electronic converters can offer reduced fuel consumption and maintenance plus increased operational flexibility and availability. Some of the issues concerning continuity of power, power quality and system stability are now being addressed. This paper considers...
This paper presents the initial results obtained from a newly developed FPGA based traveling wave fault recorder installed on a medium voltage (MV) distribution line. The recorder is capable of recording six input signals, simultaneously sampling at 40 mega samples per second (MSPS) and at 14 bit resolution. It uses high bandwidth 17 MHz Rogowski coils connected to the secondary of a current transformer...
This paper presents an FPGA based fault recorder capable of recording fault transient signals on MV distribution systems for both single and double ended fault location schemes. The proposed platform consists of a Xilinx Spartan-3 FPGA device; Texas Instruments 125 MSPS, 14 bit ADCs; Cypress 167 MHz 2 Mx 18 bits QDR memory; a high speed USB 2.0 link; and a GPS unit to provide accurate timestamps....
