Title: Current compensation method and device for power system protection
Inventor: WANG JIANPING
IPC: H02H3/28
Filed: 2001-07-11
Abstract: The present invention relates to a method for current compensation of a protection system for protecting a zone in a power system, which zone comprises a number of transmission lines connected to power sources and a number of transmission lines connected to a number of loads where the power sources and the loads are arranged outside the zone and a number of current transformers (CT) arranged to the transmission lines, wherein the method comprises the steps of continuously measuring all the incoming currents (I<SUB>in</SUB>) to the zone, continuously measuring all the outgoing currents (I<SUB>out</SUB>) from the zone, continuously calculating the differential current (I<SUB>d</SUB>) according to I<SUB>d</SUB>=I<SUB>in</SUB>-I<SUB>out</SUB>, continuously calculating q=I<SUB>out</SUB>/I<SUB>in</SUB>, continuously comparing q with set values and continuously comparing I<SUB>out </SUB>with a set value Set1. The invention is characterised by setting I<SUB>out</SUB>=I<SUB>in</SUB>=I<SUB>comp </SUB>at the instant when q changes and I<SUB>out </SUB>exceeds the value set1, which is an indication of the occurrence of a fault external to the protection zone due to saturation of the CT of the faulted outgoing transmission line, and using the value I<SUB>comp </SUB>in the protection system in order to prevent tripping of the protection system. The present invention also relates to a device and a computer program product for performing the method.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE               IMPLANTABLE SYSTEM AND METHOD               FOR AUGMENTING PENILE ERECTION        ABSTRACT OF THE DISCLOSURE     A method and system for augmenting penile erection in a human male is disclosed.  An inflatable cuff is placed circumferentially around the corpora cavernosa,  the deep dorsal vein, and the cavernous veins, adjacent to the hilum of  a  penis.    Selective  compression  of  the  cuff  will function  to  restrict  venous  drainage to augment penile erection. The  cuff  is  adapted  to have  opposite  ends thereof  attached  together  and  at  least  one  inflatable vesicle is formed on the inner side of the cuff.  A pump, including  an  attendant  control  system,  is  sized  for implantation in  a  scrotum  whereby  the  pump  can  be selectively squeezed to inflate and fluid pressurize the vesicle to compress the cuff around the penis.  A control circuit, connected between the cuff and the pump, functions to automatically deflate the cuff after a predetermined period of time has elapsed.
