摘要： PROBLEM TO BE SOLVED: To prevent a rail electric potential from rising even if an AT territory is lengthened in an AT electric current feeding system. SOLUTION: Low resistance grounding is carried out at a CPW point where a protective line and the impedance bond neutral point are connected to each other between the point (AT point) where an automatic transformer (AT) is installed and another AT point. As a result, when an electric train reaches the center between AT points, the maximum potential itself generated in the rail at the position is reduced to approximately one fourth compared with that in the case where any measures such as CPW and grounding are not taken.

摘要： PURPOSE:To supply stable power and further to attain smooth switching from existing line specification to new Shinkansen line specification by providing a tap, switching trolley wire voltage to the new Shinkansen line specification and to the existing line specification, in an autotransformer of 1:n system. CONSTITUTION:In the case of running an existing line electric rolling stock 6 on a rail 5 of existing line specification, power supply voltage of 55kV is supplied as the existing line specification from a substation 1 accross a trolley wire 2 and a feeder wire 3. A switching tap 7 of an autotransformer 4 is left as switched to a side of an existing line specification contact B. In the case of switching to new Shinkansen line specification, the power supply voltage of the substation 1 is switched to 63kV, and the switching tap 7 is switched to a new Shinkansen line specification contact A. Even before and after switching by the switching tap 7, since voltage between rail/feeder is fixed to switch only trolley wire voltage matched with the existing line/new Shinkansen line, changing the power supply voltage from the substation is only required by a voltage difference 8kV between the existing line specification and the new Shinkansen line specification.

摘要： PROBLEM TO BE SOLVED: To realize a vector relay for a feeder capable of extracting fundamental wave current, second and third higher harmonics and the like by a combination of digital filters without using Fourier transformation, and attaining reduction in computing load and error. SOLUTION: The feeder currents in a railway AC feeder circuit are taken as samples at shorter intervals than those of rated frequency thereof and the sample data are stored. The data are computed and stored so that they permit the detection of a change in the magnitude and phase of the feeder current in the data obtained by subtracting the feeder current data of n-cycle before that of system frequency from the present feeder current data stored in a sample holding means. A fundamental wave component is taken out from differential current data by combining digital filters, thereby conducting computation for eliminating other low harmonic components. The amplitude is determined by amplitude computation based on the differential fundamental wave data, and evaluated in comparison with a predetermined value as protective operation.
