The project developed an outdoor full-voltage, full-current long-term performance evaluation platform, proposed a long-term performance assessment method for electronic transformers, analyzed the impact of key components and key parameters of electronic transformers on its reliability, and studied active electronic systems. Main failure modes and fault self-diagnosis methods of transformer laser energy supply module; monitoring and analysis of the changing trend of measurement error of various electronic transformers within one year; and the interaction between electronic current and voltage transformers were studied.
Through the implementation of the project, it effectively discovered and solved multiple hidden defects in the operation of electronic transformers, improved the reliability of application of electronic transformers, and supported the construction of a new generation of smart substations to expand demonstration projects.
