Title: Method for controlling a static converter in an hvdc power transmission system and a converter with control means for carrying out the method
IPC: H02M7/757
Filed: 1985-08-15
Abstract: A method for controlling a converter in an HVDC power transmission system and a converter with appropriate control means for carrying out said method. The current regulator influences the control angle of the converter in dependence on the difference (I0-Id- DELTA I) between, on the one hand, the measured current (Id) and, on the other hand, the current order signal (I0) decreased by a current margin value ( DELTA I), controlling the converter with a control angle which is dependent on the one hand, on a proportional component being linear proportional to said difference and, on the other hand, on an integral component corresponding to the time integral of said difference. The current regulator has a proportional regulator part (PR) and an integrating regulator part (INT1). The output signal of the integrating regulator part is limited in the upward direction to a value corresponding to a maximum value of the control angle of the converter. The output signals from the integrating and the proportional regulator part are added to form the output signal of the current regulator. The limiting value of the integrating regulator part is calculated by a calculating circuit as a function of the current order and the ideal direct voltage of the converter. The calculation is made by determining the control angle at which, at a load current equal to the current order, the extinction angle becomes equal to the smallest permissible turnoff angle. From this angle there is then subtracted the output of the proportional unit at a current equal to the current order, and the result constitutes the limiting value for the integrating regulator part.

IPC: A61M5/165
Filed: 1986-07-31
Abstract: The cap and connector assembly (31, 16) portion of the 
unit protects an administration kit (11, 13, 15) from contami­
nation during the priming of the kit. A first portion of the cap 
(31) serves to close off the material flow route through the 
connector (16), but the first portion can be removed by 
tearing it away from the second portion at a weak area (33), 
thereby opening the material flow route and allowing the 
administration kit to be primed. As the system is primed, the 
second portion of the cap (31) protects the outer surface of 
the connector (16) from contamination by material flow. 
After the administration set has been primed, the second 
portion of the cap (31) is removed, thereby exposing the 
outer walls of the connector (16) for mating with a com­
plementary connector (27). The housing of the filter assem­
bly (36) of the unit includes three ports for material flow. 
First and second ports (36a, 36b) are adjacently positioned 
on one side of the housing (36) so as to cooperate to recir­
culate the material without the material passing through the 
filter material within the housing. The third port (36c) is 
located on the housing (36) such that material flow between 
the third port (36c) and either the first or second port (36a, b) 
requires the material to flow through the filter material (47).

The equivalent ratio of acid groups to alkylene oxide groups is from 1:0.8 to 1:1.7. The catalysts are reaction products of alkoxides with at least 3 C-atoms with ammonia, piperidine, piperazine and/or C2-C6 aliphatic, polyamines, preferably diamines in which all of the NH-functional groups have been alkoxylated. The resultant oligoester may then be reacted with a polyisocyanate optionally in the presence of known additives, such as blowing agents and catalysts.
