Abstract: This article systematically studies the installation process and debugging methods of key electrical equipment in power systems, focusing on four core aspects: IGBT drive system parameter configuration, high voltage equipment assembly accuracy, secondary system integration, and grounding reliability. By quantitatively analyzing the technical indicators and process control requirements during the installation phase, the decisive impact of mechanical positioning accuracy, electrical parameter stability, and medium purity on the long-term operational stability of equipment is clarified. At the level of debugging technology, a dynamic switch characteristic verification system for IGBT based on dual pulse testing is proposed, which balances switch losses and electromagnetic interference risks through gate resistance optimization selection | a multidimensional detection method for insulation status of high-voltage equipment and a secondary protection logic verification process driven by the entire transmission test are established to ensure that the fault action response time is less than 10ms. Further research reveals the closed-loop quality control logic of the entire installation and commissioning process: accurate implementation of physical layer parameters is the foundation, dynamic verification of transient working conditions is the key, and mutual calibration of multidimensional detection data is the guarantee. This system provides a quantifiable technical implementation path for improving the operational reliability of smart grid.
