The Quality of Service（QoS）of the power dispatching data network has a significant influence on power system production management and scheduling operation.The QoS model can be presented to evaluate the operational status of the power dispatching data network.It can also measure the satisfaction of the power dispatching data network QoS requirements for grid operation.Based on the analysis of multiple QoS related concepts

we consider the interaction of multi-QoS indicators.Considering the characteristics of power dispatching data network users and power service

we build a generalized QoS model

which is user-centered and business-oriented.In the integrated QoS model

the user’s view will be integrated and the QoS of the power dispatching data network will be described with multiple viewpoints.The proposed QoS model can provide new service quality dimension for the power dispatching data network.
