NEW GENERALIZED CONCEPT FOR THE DESIGN OF THYRISTOR PHASE-CONTROLLED VAR COMPENSATORS .1. STEADY-STATE PERFORMANCE

The paper presents a new generalized concept for the design of thyristor phase-controlled reactors. The generalization brings out a whole new range of possible designs from which an optimum can be selected. The most attractive features of the new designs are that they produce less harmonics and appear cost effective due to savings possible in filtering and valve equipment. The paper develops a general analysis, and presents algebraic expressions for the harmonic magnitudes which can be readily used even for the known designs.
