Title: Method of fast super decoupled loadflow computation for electrical power system
Inventor: PATEL SURESHCHANDRA B
IPC: H04N5/30
Filed: 1993-11-09
Abstract: SUPER DECOUPLED LOADFLOW METODS      ABSTRACT          The complete patent specification involves the invention  of six  super decoupled loadflow methods.  The Fast Super  Decoupled Loadflow   (FSDL)  method  and  two  variants  Transformed   Fast Decoupled Loadflow (TFDLXB and TFDLBX) methods are known ones and included  are  their novel versions  (NFSDL,  NTFDLXB,  NTFDLBX). These  are the best versions of many simple variants with  almost similar performance.  These methods specifically involved the use of the following invented technics in the prior art method.   1.   Gain  matrices of all the six methods are different and they can  be  determined  as  described  in  the   specification. Obviously  the gain matrices of P.THETA.-subproblem can be defined unsymmetrical.   2.    In  all the six methods,  rotation angles are restricted to the maximum  value   of  -36   degrees   from   nonlinearity considerations.   3.   Slack-start for any decoupled loadflow method for efficiency 4.    Modification of real power mismatches at PV-nodes according to  relations  (12) and (15) of the specifications  for  the methods FSDL, TFDLXB, TFDLBX.   5.   Computation  of angle correction and updating  for  PV-nodes along with the voltage magnitude corrections at PQ-nodes for NFSDL, NTFDLXB and NTFDLBX methods. In the back-substitution part  of  the solution of this  subproblem  involving  angle corrections at PV-nodes and voltage magnitude corrections at PQ-nodes,  skip  factor  elements corresponding to rows  and columns of PV-nodes in the calculation of voltage  magnitude corrections.      The specification deals only with unadjusted super decoupled loadflow solution methods and does not describe any applications. However  the  computer algorithms can be  appropriately  modified for  adjustments  and/or applications such as  state  estimation, contingency analysis etc.      Also described and claimed is the  invention of two  compact storage  schemes  for  gain matrices ofthe FSDL  method  and  two efficient  procedures for node type switching implementations  in the FSDL method.

Title: Process for the Compensation of Changes of the Light Source Wavelength in a Closed Loop Fibre-Optic Sagnac Interferometer for Measuring a Rate of Rotation
Inventor: KEMMLER MANFRED
IPC: G01C19/72
Filed: 1993-12-30
Abstract: In the process, according to the invention, for the compensation of changes of the wavelength of the light source of a fibre-optic gyro having a closed reset control loop, use is made of the finding that the voltage range which is required for a phase shift of 2.pi. in a phase modulator (4) is dependent upon the light source wavelength. Since the voltage required for the 2.pi. phase shift is regulated, according to the invention the voltage value which is thus available can be utilized for the compensation of a change of the light source wavelength or of the scale factor. Moreover, in order to achieve a precise compensation it is necessary to take into consideration the temperature of the phase modulator (4).
