Generator Protection System And Method For Phasor Estimation And Frequency Tracking During Frequency Ramping

View page
US Patent:
58324135, Nov 3, 1998
Filed:
Sep 29, 1997
Appl. No.:
8/939514
Inventors:
Joseph P. Benco - Germansville PA
Frederick P. Perfect - Mohnton PA
David G. Hart - Raleigh NC
James D. Stoupis - Raleigh NC
Assignee:
ABB Power T&D Company Inc. - Raleigh NC
International Classification:
G01R 2310
G01R 2316
US Classification:
702 77
Abstract:
A method for estimating phasors and tracking the frequency of a signal during frequency ramping is provided. The method uses a variable N-point DFT periodically to compute one or more phasors based on data acquired from one or more sampled signals. The period between DFT computations is a predetermined number of sample periods. After each DFT computation, the change in phasor angle between the current phasor estimate and the most previous phasor estimate is determined and used to estimate the instantaneous frequency of the signal. The current instantaneous frequency estimate and the most previous instantaneous frequency estimate are averaged to compute an average cycle frequency. In addition, a number of discrete frequencies and corresponding DFT windows based on a fixed sampling rate and a predetermined fundamental frequency of the signal are defined and used in estimating the instantaneous frequency. Once the average cycle frequency is determined the DFT window is adjusted by setting it equal to the DFT window corresponding to the discrete frequency closest to the average cycle frequency. A generator protection system analyzing voltage and current signals output from a generator is also provided.

Process For Aluminothermic Production Of Chromium And Chromium Alloys Low In Nitrogen

View page
US Patent:
43314759, May 25, 1982
Filed:
Jul 28, 1980
Appl. No.:
6/172545
Inventors:
Frederick H. Perfect - Wyomissing PA
Assignee:
Reading Alloys, Inc. - Robesonia PA
International Classification:
C21B 1502
US Classification:
420428
Abstract:
A process is provided for the aluminothermic production of low nitrogen containing chromium and chromium alloys, said chromium alloys comprising about 80% chromium, about 20% nickel and less than 0. 005% nitrogen, said alloys being especially desirable for use as master alloys in production of super alloys where levels of nitrogen imparted by chromium alloying elements are critical.

US Patent:
39829243, Sep 28, 1976
Filed:
Aug 6, 1973
Appl. No.:
5/385631
Inventors:
Frederick H. Perfect - Wyomissing PA
Assignee:
Reading Alloys, Inc. - Robesonia PA
International Classification:
B22F 900
C21C 700
C22B 4700
C22C 104
US Classification:
75 5BA
Abstract:
Carbide addition agents comprising (a) from about 20 to about 60 atomic percent of carbon, (b) from about 25 to about 60 atomic percent of at least one metal selected from the group consisting of vanadium and columbium, and (c) from about 10 to about 40 atomic percent of at least one metal selected from the group consisting of iron and manganese, are useful alloy addition agents for steel.
