Overview

Randomized trial evaluates parameter measurements in thyristor components, indicating improved accuracy without disconnection.

Key Points

  • This research aims to develop a method for measuring parameters of thyristor-level components without wire disconnection.
  • Proposed a measurement method using the Broyden quasi-Newton method.
  • Established equations for DC voltage-balancing resistors, damping resistors, and damping capacitors.
  • Utilized MATLAB/Simulink for validation of results.
  • The proposed method achieved higher measurement accuracy compared to direct measurement techniques.
  • Successfully reduced errors from external-circuit shunting.
  • Maintained intact wiring of the converter valve throughout the measurement process.
