Title: Harmonic Composition of the Currents of Power Windings in 500 KV Thyristor Controlled Shunt Reactor with Split Valveside Windings

Abstract

The design and current spectrum of a thyristor valve controlled shunt reactor (TCSR) with split valveside windings are described. The dependence of the amplitudes of higher-order harmonics of the power winding current on the TCSR operating regime are presented for this TCSR design.

  • Harmonic analysis based on Kirchhoff laws requires the knowledge of the spectral information of the injected currents. In practical operation of controlled converters, these current harmonics depend on the actual operating point given by the emf and the dc mean current according to the requirements of the dc load. This specification means a more difficult predetermination in the case of a rippled dc current due to the unknown control and overlap angles. To simplify harmonic power flow studies, the results of systematic evaluations are outlined graphically depending on the dominant parameters operating point and circuit reactances.
  • The main objective of this paper is to report on a newly developed three phase Thyristor Controlled Reactor (TCR) model which is based on the use of harmonic switching vectors and discrete convolutions. This model is amenable to direct frequency domain operations and provides a fast and reliable means for assessing 6- and 12-pulse TCR plant performance at harmonic frequencies. The use of alternate time domain and frequency domain representations is avoided as well as the use of FFTs. In this approach, each single phase unit of the TCR is modelled as a voltage-dependent harmonic Norton equivalent where all themore » harmonics and cross-couplings between harmonics are explicitly shown. This model is suitable for direct incorporation into the harmonic domain frame of reference where all the busbars, phases, harmonics and cross-couplings between harmonics are combined together for a unified iterative solution through a Newton-Raphson technique exhibiting quadratic convergence.« less
  • A detailed analysis was carried out of a fixed capacitor thyristor-controlled reactor type compensator, for dynamic power factor correction and terminal voltage stabilization of a thyristor phase-controlled inductive load. An equation for the firing angle of the reactor and Fourier coefficient equations of the load current, supply current and compensator current were derived and compared for typical circuits. Variation with load thyristor firing angle of the rms values of these currents, the firing angle of the compensator thyristor, the power factor and other quantities were tabulated and plotted as graphs. The magnitudes of different harmonic components of the three currentsmore » were also determined. It was discovered that, for load phase angles of less than 45 degrees, the load susceptance must be such that the lagging reactive component of the fundamental component of the load current at most load thyristor firing angles.« less
  • Thyristor controlled phase shifters can be applied to power systems to re-distribute line power flows. A method is presented in this paper to determine the optimal number of phase shifters and their locations in the network to minimize line real power losses for a power system in steady state operating conditions. Phase shifters also provide series compensation to augment stability. They primarily change damping torques of machines to improve the machine's dynamic behavior. From the electrical distance point of view, the phase shifter at a machine terminal gives the greatest change of electrical distance between that machine and the disturbancemore » point. Therefore the best location of a phase shifter for a machine is at its terminals. Comparisons are made to show that the phase shifter can significantly increase damping as compared with machines having no regulation and machines having exciter-augmented stability.« less
