Study On Evaluation Of Heat Consumer Comprehensive Reliability

Based on the previous theoretical studies of the heat customer reliability analysis,this paper do further research on the scope of application,calculation method and influencing factor of the indicator of heat customer comprehensive reliability,in order to realize the evaluation of the heat customer reliability and get feasible ways to improve the heat customer reliability.Depending on the degree of failure and accident,the heat customer reliability can divide into two grade.The four specific expression form of the indicator of heat customer comprehensive reliability apply to the reliability evaluation of heat customer of different grades respectively.On the basis of the basic calculation method of the indicator,the calculation method of the indicator of heat customer comprehensive reliability of indirect connection system,taken fault condition of the components of the primary and secondary network into account,hav e been derived.And the indicator of heat customer comprehensive reliability which can reflect all heat customer reliability in the whole heating system have been proposed.Under the fault condition,the fault flow which the heat customer can get directly influence the heat customer reliability.This paper study the fault hydraulic regime of the uncontrollable system and controllable system respectively and its influence to the controllability.Through analysis,homogeneous flow can ensure the heat customer reliability.But the fault flow which the heat customer can get should be checking when we design the controllable system.By having done a secondary development to the analysis procedure of the heat supply reliability based on Auto CAD,the calculation of the indicator of heat customer comprehensive reliability in the visual interface have been realized.And the procedure realize three basic function for analyzing pipe network and provide convenient tools for the following study.At last,the indicator of heat customer comprehensive reliability of a real heat supply system has been calculated and the influence factors of the indicator of heat customer comprehensive reliability have been analyzed combining with the example.And methods of improving the two grade heat customer reliability have been gotten.
