In light of massive information and heavy task of equipment overhaul，and heavy reliance on manpower and strong subjectivity in overhaul operation mode，grid overhaul scheduling combined with operation mode selection are comprehensively analyzed.The design and development of an intelligent overhaul and safety check management system for 110 kV distribution network are presented. By using TWaver and computer advanced technology，a complete set of modeling，management and evaluation system is formed，and the aim of grid data visualization，grid on-line monitoring and early warning is achieved.Based on genetic clustering algorithm，the overhaul scheduling intelligent compiling and operation mode assisted analysis of grid equipment are completed.The effectiveness of the system is demonstrated by introducing its system functions and application example.
