Data integration used in new applications and control center visualization tools

Nowadays, most substations are equipped with Intelligent Electronic Devices (IEDs) performing data collection. With the advancement of measurement techniques and growing availability of information captured by newly emerged IEDs such as Phasor Measurement Units (PMUs), it is imperative to integrate the various data sources with traditional Supervisory Control and Data Acquisition (SCADA)/Energy Management System (EMS) structure. This paper explores several possible solutions for data integration and its applications in power system. Also addressed is a set of new visualization tools to be used in power system control center. It shows that the merging of Remote Terminal Unit (RTU), PMU and other substation IED data could effectively improve the ability to detect cascades, efficiently process alarms, and accurately determine the location of faults. The resulted intelligent control center visualization tools could enrich monitoring capabilities and help operators maintain adequate situational awareness.
