Abstract： [Purposes] To improve the operational eficiency and safety of 500kV substations，an integrated automation remote control technology for 5OO kV substations is proposed.[Methods] First， system analysis and engineering verification were applied to study key technologies including communication protocols，one-key squential control，and capacitor/reactor groupcontrol; second，asemi-physical simulationplatform was constructed to test system functions and performance，folowed by verification in actual engineering applications to comprehensively evaluate its technical feasibility and operational stability.[Findings] The technology significantly enhanced the automation level of substations，reducing operation response time to 1.5 seconds，increasing equipment utilization rate to 94.7% ， improving voltage qualification rate to 98.9 % ，achieving an operation success rate of 99.8% ，and lowering operation and maintenance costs by 35% . [Conclusions] By optimizing the network architecture，improving the security protection system，and strengthening system integration，the reliabilityand safetyof substation remote control were effctively improved，providing reliable support for the intelligent operation of substations.
