With the rapid development of smart grid technology, substation comprehensive automation technology has made significant improvements. However, the intelligent operation function of monitoring and operation and maintenance is still not perfect, such as the reversing operation process is still
The multi-circuit coupling transmission mode is an inevitable trend of power grid construction, mainly with partially coupled multi-circuit lines. Affected by the local coupling between lines, the existing fault location methods have large errors. To this end, fault analysis and fault location
In hydraulic cylinder systems, oil pollution results in wear and leakage of hydraulic cylinder components. In accordance with the actual working conditions of a certain type of hydraulic cylinder, the technology of fluid–solid thermal coupling and multiphase flow analysis is applied to analyze
