Research on Error Prevention Technology of Secondary Security Measures Based on Substation Intelligent Operating System
The secondary system of the intelligent substation replaces the wired communication of the traditional substation with network communication,which greatly improves the information sharing of the substation,but also brings the problems of complex operation of the secondary security measures and difficulty to ensure the reliability.Based on the concept and basic principle of secondary safety measures in intelligent substations,the reasons for low reliability of secondary safety measures are analyzed.According to the actual work experi-ence,three solutions are given,i.e.,pre-check,online error prevention and automatic generation of secondary security measures.Combined with the difficulties of engineering application,the future development direction of secondary safety measures is given.
