This paper studies the segmented thyristor controlled reactors ST CR used to control the inductive reactive power with zero harmonic content in the developed current. This paper explains how to use STCR to produce inductive reactive power with discrete steps of operation from zero to full reactive power rating of the inductor. Paper studies several topologies used as STCR and illustrates the specifications...
This paper provides new topologies for thyristor controlled reactors (TCR) used for static VAR compensators (SVC). This paper explains the need for these new topologies by providing the harmonic analysis of each type. The conventional TCR, two parallel TCR, two tapped inductors TCR and three tapped inductors TCR are explained and evaluated to be impeded in the SVC system. The design of each type is...
This paper provides optimal design of new topologies of the thyristor controlled reactors TCR used in static VAR compensators systems SVC with zero harmonic content. The paper discusses the principle of operation of the new topologies which depends on thyristor switched reactors TSR. The objective function and its constrains to get optimal design of such topologies are suggested to get proper reactive...
This paper provides new thyristor controlled reactor (TCR) used for static VAR compensator (SVC). The concept of this modified thyristor controlled reactor MTCR depends on modifying the waveform of the developed current by adding auxiliary circuit. The auxiliary circuit consists of back-to-back thyristors, inductor and capacitor. The developed current be the MTCR has less harmonic content. This paper...
This paper presents the design of static VAR compensator (SVC) for 27.5 kV West Siberian Railway system. The SVC is designed to adjust the voltage profile and power grid performance between two supplying stations. The design of SVC power components depends on adjusting the system voltage profile and increasing railway power grid efficiency. The design of such SVC includes the determination of SVC...
Linear generators have been proposed as a proper power take-off system for direct-drive wave energy conversion. Coupled directly to a reciprocating wave energy device, it was proposed that linear generators could replace hydraulic and pneumatic systems. Here we established the design and performance evaluation of a permanent magnet linear generator that implements Halbach array arrangement. The designed...
