Abstract
- An approach for controlled reclosing of transmission lines with shunt reactive compensation is proposed here to reduce switching surge overvoltages. It consists of applying Karrenbauer's transformation as a matrix operator for the analysis of voltage signals required to control switching operations. The procedure also determines the arc extinction time for single and double-phase-to-ground faults which may avoid unsuccessful reclosing. A device to control the line reclosing was implemented and evaluated through real-time simulations. An offline version was implemented for parametric and sensitivity analysis through the Electromagnetic Transients Program using actual parameters from the Brazilian Power System Grid. Several field oscillographic data, obtained from Brazilian power transmission lines with different transposition schemes, were used to validate the proposed approach, and the results attest its efficiency.
