Power grid is a power energy transmission network based on all kinds of power grid equipment

in order toensure the safety

reliability and continuity of power supply

under the conditions of full and intensive resource allo-cation

power grid equipments daily maintenance gradually developed into state maintenance. That is

according tothe equipment state indicators and state evaluation presentation

determine the equipment state

and develop target-ed maintenance strategies. However

as the grid scale increases exponentially

the number of power grid equipmentincreases exponentially

there are many untested

unmeasured and unevaluated power grid equipment in the cur-rent state maintenance mode

whose state is uncontrollable;there are also tested

measured and evaluated powergrid equipment

which still have faults. Therefore

by running large data analysis equipment state inspection equip-ment foundation means effectiveness

innovation evaluation index

set up mathematical model

quantitative calcula-tion of feasibility and optimization of key state quantities

to study the feasibility of cancel routine test power

the powergrid equipment differentiation state maintenance of new pattern research

put forward a more efficient way of statemaintenance.
