Abstract:  In order to improve the efficiency of temperature control and deployment，a new optimization algorithm
for the operation and maintenance of integrated power warehouse is proposed． Based on the solution of space
dividing original idea，design solution space segmentation processing mechanism，application solution space
segmentation processing mechanism，the current comprehensive utility tunnel power operations，the different
voltage grade evaluation，the current utility tunnel power storehouse magnetic field，electromagnetic field data
capture are calculated，the natural convection into simultaneous solving differential equation，energy equation is
solved simultaneously to calculate the conduction data of the current power operation and maintenance of the pipe
gallery． Finally rely on the solution space division，the above to calculate the magnetic field calculation of power
storehouse data and the analysis of convective parameters，delimit the molecular space respectively，clear number
and individual number space，the optimal solution is obtained and the operation and maintenance upgrade is
realized． Experimental data show that the local maximum temperature has been reduced by nearly 27%，and the
absolute temperature has been reduced by 32%．

Key words: pipe gallery power warehouse, operation and maintenance operations, energy equation
