To timely master the real-time operation status of the smart grid dispatch and control system(D5000 system)

a hierarchical priority health evaluation method based on the integration of multifarious business and hardware is proposed according to its characteristics such as multifarious business

complex business hierarchy

business tightly coupled with the hardware

and the special way of working. Firstly

based on the business hierarchy of dispatch control system and the priority layered principle

a D5000 directional index system framework is established; Secondly

by taking the supervisory control and data acquisition(SCADA)core application as an example

a D5000 system hierarchical evaluation index system for fusing business health

hardware health and master-slaves architecture is built; Then

by using the analytic hierarchy process(AHP)and drawing on expert experience

the weights of indices and evaluation standards are determined; Finally

the weighted average method and the parallel system health degree method are used to implement the comprehensive evaluation of the D5000 system. On the basis of the real-time field data

the results of a case in point show that the proposed evaluation index system and related method are easy to implement and the real-time operation status of the D5000 system can be accurately reflected in an all-round way.
