The secure and reliable operation of natural gas compressor is very important because natural gas transmission pipeline project increases continuously.The accuracy of dynamic safety assessment is not high using traditional security monitoring method because target weight does not have the adaptive ability with the condition changing.An adaptive deployment mechanism of index weighting and an integrated assessment model based on 3-D time perspective were proposed using game theory.Taking gas-turbine/compressor of a gas booster station as instance,the assessment analysis was done using the method.The results show that the safety states are tracked and predicted dynamicly based on the proposed methods,which is conducive to improve the accuracy of assessment in dynamic environment.The fault symptoms are restrained.The validity of the method was proved by field test.
