Architecture design and implementation of substation dashboard oriented to O&M center

To improve the “substation owner” control mechanism and support the conversion of substation operation and maintenance (O&M) operators to “substation owner”, in this paper, an architecture of substation dashboard oriented to O&M center is designed, which brings about integration of multiple O&M systems and collaborative operations of substations. A unified information platform is established on the base of the extended IEC61970 model. An integrated monitoring and control system is built by standardizing the three-screen interactive interface including power grid monitoring screen, equipment monitoring screen, and O&M management screen, designing the multi-dimensional and multi-layer key performance indicator (KPI) system, and developing the advanced application functions including monitoring, diagnosis, operation and coordination. The substation dashboard system designed in this paper has been piloted at the Foshan 220 kV Hongxing O&M center. It simplifies the existing dashboard system, makes information standard, unifies interfaces, and promotes collaborative operations. By providing one-stop services and centralized control for O&M of substation, it makes substation more observable, measurable, controllable and evaluable.
